From takeoff to landing, all aircraft require some sort of electrical power for important functions such as navigation, intercoms, COM and NAV radios, and more. With in-flight entertainment and increasingly modernized systems, this need for electricity is ever more present. To get power, aircraft often use electric power generation through generators and alternators. Both of these systems produce power for the aircraft but differ in method, as well as have various benefits and drawbacks when compared to each other.

The aircraft generator works through a stationary magnet and a rotating electromagnet that spins within the magnetic field, producing an electrical current for use. Generators are simple and produce power by mechanical motion. For generators to start producing ample power for charging the aircraft battery, however, the engine RPM usually needs to exceed 1200. Generators also have the drawback of being very heavy and require maintenance such as cleaning and greasing often.

Aircraft Alternators, on the other hand, are becoming widely used on more modern aircraft, which require more power from the start of the flight, as well as with changing systems. Alternators utilize rotating magnetic fields in a stationary coil to produce electricity. Alternators have the benefit of being able to produce at full output while the engine remains at low RPM. They also have the benefit of being very light as compared to standard generators, due to not having a heavy internal magnet. With their higher idling power generation and light weight, alternators are useful for many aircraft.

While alternators generally are seen as more favorable compared to generators for many aircraft, there are still some benefits of the generator that can outweigh those of the alternator. For one, generators do not require the extra circuitry that alternators do to convert alternating currents to direct currents. They are also not sensitive to problems that alternators face, such as reversed polarity and errant electrical spikes. Lastly, generators have the ability to produce power even when the battery is dead.

Despite their differences, the generator and alternator are both very viable aircraft electric power generation options for providing electricity during successful and smooth flights. Both have their various benefits and drawbacks that make them fairly equal contenders to each other depending on the type of aircraft and their needs. Alternators prove useful for modern aircraft and those that need power from the very start of the flight. Generators, on the other hand, are simplistic, reliable, and have less sensitivities to possible outside forces.

The aircraft electrical system is a network of components that transmit, distribute, and store electrical energy. Most modern aircraft have a 28 volt direct current electrical system, which typically consists of a battery, the master switch, alternator, an ammeter and a loadmeter,. Through the electrical system, the aircraft’s taxi lights, landing lights, radio equipment, interior cabin lights and other equipment are supplied with power. For a detailed look at some of the important components and the roles they play, read below:

Aircraft Electric Alternators

The alternator’s job is to supply energy to the electrical system, while also maintaining enough charge in the battery. There is typically sufficient energy stored in the battery that will start the engine and a small amount available for use as an emergency backup in case the alternator or generator die. You can use either the alternator or generator to produce an energy supply, but some mechanics prefer the alternator because of its advantages. They generate enough of a current to operate the entire electrical system by producing alternating current  (AC) and converting it to direct current (DC). With this advantage, the aircraft alternator can generate a much more consistent electrical supply throughout different engine speeds.

Voltage Regulator

The voltage regulator is responsible for stabilizing the generator or alternator electrical output of the battery. It does this by controlling the rate of charge and making sure that voltage output is higher than the battery voltage. For instance, the difference in voltage that results from a 28 volt generator feeding a 14 volt battery would be able to keep the battery charged.

Ammeter

Ammeters are used to monitor the well being of the aircraft electrical system. Designed like a dial, with a zero point in the center and negative or positive to each side the ammeter shows if the alternator or generator is making enough power and can also indicate if the battery is receiving enough charge. When the indicator is leaning to the right positive side, that shows the charging rate of the battery. If it is on the left, then that means there is more energy being pulled from the battery than is being replaced. Any extreme indication on either side, means that either the alternator/generator is malfunctioning (minus deflection) or the regulator is malfunctioning (positive deflection).

In aviation, each piece of machinery has an important role. Parts need to be tough and dependable to put up with the rigors of air travel. However, no matter how well-crafted a piece is, it will eventually deteriorate. Connectors are fundamental to the successful operation of an aircraft. They are found in the airframe, cabin interior, navigation tools, and a variety of other important areas. Here are a few ways connectors fail and measures you can take to prevent it.

The first and most obvious reason why connectors fail is natural wear and tear. The strain put on contacts while they are constantly being connected and disconnected slowly but surely erodes the surface, weakening the connection. Corrosion will also occur over time as connectors are exposed to water, dust, dirt or other damaging particles.

Another factor that can cause connectors to fail is exposure to extreme temperatures, whether high or low. Certain connectors types are made to withstand these temperatures, but inappropriately rated connectors will inevitably fail under the stress of exposure. Failure in these instances is typically the result of the connector’s insulation malfunctioning thus causing electric conductivity to drastically increase. The increases in conductivity will only raise the already heightened temperature, resulting in corrosion. Extreme cold is generally not as detrimental to connectors as extreme heat, but it is still wise to employ designs fit for low-temperature environments whenever possible. Long-term exposure to low temperatures can cause tin-plated connectors to malfunction as well as weakening plastic components of the connector.

Just as connectors not prepared for extreme temperatures are ineffective, connectors not prepared for exposure to moisture will suffer the same fate. For instance, if a standard connector is used in place of an IP68-rated connector, water will present problems. IP68 connectors are sealed and completely waterproof. Using too small a connector can also be detrimental to its function. If a connector is not the appropriate size it will be less efficient, thereby forcing it to work much harder and reducing the part’s lifespan.

The most preventable issue some connectors face is faulty design or installation. Because of the wear and tear that connectors invariably experience, secure installation is key to the tool’s function. Without a strong connection, the mating components and cables can suffer damage. It is important to always buy the proper connector for the task and take care in installing correctly. At ASAP Buying, we have a variety of high-quality connectors as well as many other NSN and military parts. To learn more about our vast inventory, contact us at 509-449-770 or sales@asapbuying.com.

Atmospheric density is a serious concern for weather, guiding wind patterns and rainfall, but it can also seriously affect flight conditions. Takeoff, climbing, and landing performances and parameters all change depending on atmospheric density, and failing to recognize these changes can lead to serious accidents. Thus, let’s take a look at what exactly density altitude using density indicator , and how it affects performance.

According to the Federal Aviation Administration’s Pilot’s Handbook of Aeronautical Knowledge, density altitude is the pressure altitude corrected for variations from standard temperatures. When conditions are within standard parameters, the pressure altitude and the density altitude are the same. But when nonstandard conditions are present, such as high altitudes, high humidity, and high temperatures, air density increases, and the density altitude increases. Effectively, this can make an aircraft flying at 3,000 feet behave as though it were flying at 6,000 feet.

Why is this important? Because high density altitude means lower air pressure, which has a detrimental impact on aircraft performance. Less air pressure means less lift on the wings, and poorer propeller efficiency, which reduces thrust. High density altitude also decreases the engine’s power output, which means slower flight speeds. If it isn’t accounted for, increased density altitude can also cause major problems during takeoff and landing, where having enough thrust to operate the aircraft is critical. Hot and humid weather can easily make a routine procedure far more dangerous and difficult than it should be.

Pilots need to be careful during preflight planning on hot and humid days, and adjust for increased density altitude to avoid accidents during takeoff and landing. At airports with higher elevations, such as in mountainous regions, the high altitude combined with hot temperatures can make flight dangerous. Even at lower altitudes, hot and humid conditions need to be accounted for, as they cause increased takeoff distances, reduced rates of climb, and increased landing roll distance.

Finally, when flying in high density altitude conditions, try to keep the aircraft’s weight below 90 percent of the maximum gross weight of the aircraft. Don’t fill the fuel tanks to the top, and watch your cargo load. This may require flying shorter legs and making extra fuel stops, so keep in mind how your aircraft performs and be willing to be flexible on things like departure time and weight.

Unlike car drivers, pilots don’t wait for the change oil light to pop up on the dashboard before they change the engine oil. On average, aircraft oil is changed after every 10 hours of flight time. When the time comes, there are a few key steps that should be followed so as not to cause damage to the engine.

First and foremost, the maximum and minimum levels of the oil tank should be identified. When you fill up any type of vestibule, you want to make sure you don’t overfill the tank and cause a leak. On the other hand, you should make sure to fill the tank pass the minimum level to ensure that the system has enough oil in it to not cause internal damage to the system through system overheat or friction.

The location and timing of the oil change are important factors to consider. Prior to performing the oil change, you should monitor the oil levels over an extended time. In doing so, you can accurately gauge the oil levels and detect any abnormalities such as a leak. When you decide to carry out the oil change, the aircraft should be parked on a stable, even surface. If the aircraft is parked on a downward or upward slope, the oil level in the tank will be difficult to gauge and may lead you to mistakenly overfill or underfill the tank.

Although it may seem tempting to complete the maintenance as quickly as possible, it is important to wait 15-30 minutes after engine shut down before opening up the fuel tank. Not only is this a safety precaution, but it is also an accuracy measure. Hot oil has a larger volume than cold oil; therefore, it may trick you to believe the engine oil tank is fuller than it actually is. Again, this often leads to incorrect measuring and potential problems down the road (or tarmac in this case).

As is the principle for most maintenance procedures, consistency is key. Just as you can choose whether to fill up your car tank completely, halfway, or by the dollar amount at the gas station, you can choose how much oil to pour into your aircraft. If possible, you should try to refill the tank to the same amount each time. This simply helps to maintain accuracy and keep an eye out for any oil inconsistencies.

The final element to consider when changing your oil is the type of oil you plan on using. Manufacturers usually specify the type of oil that they use in the factory. While it is advised to use this oil, it is possible to find an alternative. Prior research should be carried out to determine whether different oils can be mixed or not. In certain cases, you may need to drain the original oil before adding the new oil. Engine oil filling devices such as funnels or fluid servicing carts are advisable so to avoid messy and possibly expensive spillages.

Many instruments exist for monitoring navigation and outside atmospheric conditions on aircraft. However, it’s just as vital to monitor the interior conditions of the aircraft, so aircraft mount numerous sensors to monitor their critical systems.

Liquids are a major component of an aircraft’s healthy operation. Oil, hydraulics, and fuel all need to be closely monitored and replaced as needed. To ensure that the aircraft has enough of these liquids, liquid level sensors are placed in the thermowells, reservoirs, tanks, sumps, and gearboxes. These sensors connect to the interface and display units in the cockpit to relay information like oil levels, fuel reserves, and others.

For some parts of an aircraft, operating temperatures must be closely monitored. The engines, for instance, are vulnerable to suffering cracks and failures if they run too hot, or too cold, or change temperatures too quickly. Therefore, temperature sensors are placed throughout the engine, such as in every cylinder. This allows the pilot to check if they are running too hot or too cold if something goes wrong during flight.

Flow sensors are often used in tandem with liquid level sensors. Flow sensors, as their name implies, monitor the flow rates of liquid, typically either fuel or oil. Mounted within the thermowell, they may also contain an electronics unit that connects to a digital exhaust gas sensor. They are typically installed in a pipe that carries liquid for which flow rate is being measured and can inform the pilot if flow is blocked or interrupted.

Pressure sensors are used to measure pressure that is either above or below a pre-set figure at that sensing location. These sensors are usually found in ducts, pipes, tanks, sumps, reservoirs, and even gearboxes in aircraft. Like other sensors, they monitor how well the aircraft is functioning, as de-pressurization or over-pressurization can cause serious stress damage to an aircraft’s fuselage or components.

One of the greatest innovations that aviation technology has made in modernizing all-weather capabilities is deicing equipment. Aircraft that do not operate in regions that freeze over can still face ice build-up as a potential issue, due to the altitude at which they operate. Ice forming along wings, aircraft propellers, and control surfaces can severely impact an airplane’s handling characteristics and performance, making deicing equipment an integral part of maintaining an aircraft’s safety.      

These measures come in two different forms.  The first are anti-icing systems, which describe all the equipment that is used before icing can occur, such as before takeoff or before flying into inclement weather.  The second are deicing systems, which are used after ice has begun to build.     

Anti-icing systems typically involve heat from one source or another. Keeping critical areas like control surfaces, adaptor pitot tubes, propellers, and windshields warm prevents water from freezing. This heat typically comes from one of two sources, the most common being the aircraft’s engines. Known as bleed air, this air is typically used in turbine aircraft to keep engine components warm and safe, or sent via ducts in the aircraft to other areas like the leading edges of wings and windshields.  Carburetor heat on piston aircraft operates on a similar principle. The downside of bleed-air systems is that they introduce excessive noise and rob the engine of power. 

An alternative method for heating critical surfaces is to use electricity, much like a toaster or hot plate, by applying an electric current to a closed circuit.  This method is typically applied to propellers, drains, and pitot-static systems. However, these systems must be activated before ice begins to accumulate, as there is no guarantee that they will get hot enough to melt away thick ice. 

Deicing systems focus on removing ice after it is already present.  Deicing comes in the form of spraying the aircraft down with an antifreeze solution similar to what is used in automobiles, a mixture of ethylene glycol and water. Because glycol has a much lower freezing point than water, it can be heated and applied to melt away ice and prevent it from forming again. This process occurs before takeoff on commercial jets. In addition, some planes carry dispensers that can apply deicing fluid where necessary. The limitation of these so-called “weeping wings,” of course, is that there is a limited supply of the fluid they can carry.  Additionally, just like the antifreeze you put in your car, this fluid is very toxic.

The final form of deicing equipment comes not from heat or fluid, but inflatable rubber strips along a wing’s leading edge. These rubber boots can be inflated, changing the wing’s shape and breaking the ice free from the aircraft.  Once the ice is gone, the boots deflate, and the wing returns to its original aerodynamic shape.  Like other methods, these boots have their drawbacks as well. Deicing boots add weight and power requirements to the aircraft.

The landing gear of an aircraft supports the entire weight of a vehicle during landing and ground operations. The components are primarily attached to the actual structure of the aircraft and has different applications for each part. Wheels are most commonly associated with aircraft landing gear, however, there are many other facets involved. Modern landing gear technology wouldn’t be possible if shock absorbing equipment didn’t exist, making shock absorption a crucial aspect of both landing and takeoff.

A shock absorber is a hydraulic device that was designed to absorb and dissipate shock impulses. It converts the kinetic energy of the shock into another form of energy, typically heat, which is then dispelled. Hydraulic shock absorbers are used in conjunction with springs and cushions. One thing to consider when choosing a shock strut or absorber is where that energy will go. In many shock absorbers, the energy it absorbs is converted to heat inside the viscous fluid. In hydraulic cylinders, the hydraulic fluid is heated while hot air is exhausted to the atmosphere.

Shock struts are self-contained hydraulic units that support an aircraft while it is on the ground; it also protects the structure of the plane during landing. Shock absorption occurs when the force of an impact landing is converted into heat energy that makes its way towards the strut landing gear.

An oleo strut is a type of hydraulic shock absorber that is equipped on most commercial aircraft. A steel coil spring stores the impact energy then releases it into the oleo strut, where it is absorbed. The design of the spring allows it to cushion the impact of landing and decompress the vertical oscillations that are produced, allowing for a smooth landing. As the strut is compressed, the spring rate has a dramatic increase, while the hydraulic oil of the oleo strut reduces the rebound motion.

Nose gear shock struts are attached to the wheel in the very front portion of the landing gear, directly under the cockpit of the plane. It is composed of a locating cam assembly which enables it to keep the gear that it is attached to aligned. The cam assembly maintains a forward position when the adapter shock strut is fully extended and allows the nose of the wheel to fit snug in the wheel well when it is retracted.

When frigid temperatures hit the north-central and north-eastern United States earlier this year, hundreds of flights were grounded or canceled due to the extreme weather. And that can make you wonder, what exactly makes cold weather so difficult for commercial flight? Just a hint, the problem is not what it seems.

Generally speaking, you might think cold weather involves an array of problems for an aircraft. From frost formation to snow accumulation, it seems like a total disaster for commercial flight. We will get to frost and snow, but, overall, aircraft are actually more efficient in lower temperatures. A colder temperature means less humidity and denser air. As a result, the aircraft engine is able to utilize a larger quantity of air/fuel mixture than it would at warmer temperatures. This process gives the aircraft engine parts more horsepower and allows it to take off and land more quickly. Often, this creates a smoother flight-feel and more efficient operation overall.

Aircraft also have numerous redundancy measures to ensure it stays heated at a proper temperature, and to ensure that frost does not form on the airframe, even in extremely cold weather. Components that have specific temperature requirements, such as fuel oil, hydraulic fluid, and internal combustion units, will have integrated systems to keep them heated; this might include preheaters or aircraft engine analyzers. As long as the aircraft is preheated and an aircraft engine preheating process is followed, the aircraft will have no problem maintaining its required temperatures for flight.

It’s critical to ensure that frost does not form on the airframe top of an aircraft. Even a small amount of frost can change the pattern of airflow over the aircraft surface, increasing drag and causing a multitude of other challenges. Most commercial airliners use antifreeze fluid to ensure this does not happen. A coat of the glycol-based fluid at the gate will ensure that frost does not form on the aircraft surface before it reaches higher altitudes. The airframe itself is built to withstand temperatures of around -40 to -70 ? while flying altitudes upwards of 30,000 ft. Due to vapor pressure in the air (vapor pressure dictates the formation of ice) frost cannot form at these altitudes.

Here’s the main issue for commercial flight— while aircraft are engineered to survive volatile conditions, cold weather is much harder on airport operations. There are no preheating methods for a frosted tarmac, nor for frozen jet fuel equipment. Despite the likelihood of hundreds of aircraft needing anti-icing treatment and jet fuel, an airport cannot keep ground operations workers outside for longer than 15 to 20 minutes at a time in frigid weather. Any addition of snow complicates air traffic control visibility, and related operations even further.

And that’s the gist of cold weather and its effect on an aircraft. Though aircraft fly more efficiently at colder temperatures, extreme cold weather is a nightmare for airport operations.

There's a strong tendency to compare aviation to the automotive industry. But, the list of similarities is short. Aircraft and automobiles couldn’t be any more different. For example, if a car engine breaks down in the middle of your commute, you can just pull over and call a tow truck or try to fix it yourself, but you can’t do that when an airplane’s engine fails. 

Aviation is all about safety, so it stands to reason that preventing aircraft engine failure is a multi-step process with many different checkpoints. The pilot performs a quick preflight inspection before every flight; the maintenance crew forms A, B, C, and D checks at specified intervals; all Aircraft Engine Parts and assemblies on the aircraft have set maintenance and repair inspection schedules; and after a certain number of manufacturer-specified flight hours, there’s the overhaul. It can be a frustrating process, so here are three things everyone should know about the engine overhaul.

The overhaul is a thorough inspection of the aircraft engine— the engine assembly is removed, disassembled, cleaned, inspected, repaired as necessary, tested according to OEM guidelines, reassembled, and reinstalled. It’s a very important process in maintaining the life of the engine and the aircraft as a whole. But there are actually two types of overhaul: top overhaul and major overhaul. The top overhaul is where the whole engine is not completely disassembled, only the parts outside of the base crankcase, such as all the cylinders and pistons. The major overhaul is when the entire engine assembly is disassembled and inspected.

It’s important that you only trust your aircraft engine overhaul with overhaul professionals. The whole point of an engine overhaul is to ensure airworthiness, that the aircraft is safe to fly. If the overhaul is done incorrectly or haphazardly, the risk of danger increases. Also, overhaul professionals are better connected to OEMs and aftermarket suppliers than the average smaller and unknown option, so they can not only conduct the overhaul properly, but they can probably do so more quickly and efficiently, ultimately saving you time and money. Overhauls are expensive as is, but utilizing a non-expert that does the overhaul incorrectly just means you either have to do redo it or you risk the loss of lives and property.

Another important thing to remember is to adhere to TBOs (time between overhauls). The TBO is the number of running or flight hours the aircraft engine’s OEM recommends between overhauls. Aircraft can’t be repaired on the side of the road when they break down the way a car does, so it’s best to stick to a strict TBO schedule and make sure that everything is taken care of before it becomes a problem. While the overhaul is a lengthy and expensive process, it’s worth it to know that you’re flying safe and sound.

When we think of the things we need to fly, we usually think of the engine. Afterall, combustion is what powers the plane. So, it’s easy to fixate on the engine and neglect the alternator. But, without the alternator, we don’t have access to our digital nav/com radios, integrated GPS, multifunction flight displays, and so on.  

The reliability of your aircraft’s alternator relies heavily on routine maintenance and inspections.  Typically, inspections happen every 100 flight-hours, with a more thorough one every 500 flight-hours.  These inspections are important because they can warn you of any impending issues, ultimately preventing a blowout or loss of power.

When inspecting your alternator, you should begin with the alternator belt.  You’re looking to make sure the belt has proper tension and pulley alignment, and that it’s free of significant wear/damage.  Just like with your car’s tires, you can tell if the alignment is off based on the wear of the belt; Most of the wear should come from the sides of the V-portion because they do must of the work.  If the wear is misaligned, this could be an indicator that the pulleys are out of place or the mounts are shifting.

Next, inspect the actual alternator.  It should be somewhat clean and free of carbon dust; the presence of significant carbon dust may warrant a more significant internal inspection of your alternator.  All electrical wires should be fully secured and without abrasions— abrasions can lead to alternator failure (dead battery) and disconnected wires can lead to a failed direct current.

The battery directly supports the alternator, which is why it is so important to inspect all of the attached wires.  The battery’s diodes allow the alternator to convert alternating current into direct current. A dead battery can still function, but, if the battery is disconnected, it serves no purpose at all.  For these reasons, it’s vital to ensure that when you’re switching from one battery to another, the system should never be without power.

From snow-capped mountains and forests of tall redwoods to scorching deserts and beautiful beaches, California is known for its beautiful and diverse landscapes. And while driving through them can be a fun experience, flying is truly the best way to see it all. But, once you’ve decided to travel by air, you’ve now got to choose how: fixed wing or rotary wing?

Fixed wing aircraft are airplanes, gliders, and other aircraft capable of flight based on the shape of their wings and the airflow over and under the wing. Fixed wings tend to be faster, capable of flying at higher altitudes, and for longer distances, making them more ideal for seeing better views in places that are farther apart. They’re also an affordable and safe way to see the sights because they don’t vibrate as much as rotary wings, so they can fly more smoothly and linearly, decreasing the chances of motion or airsickness. Also, because fixed wings are able to fly faster and for longer distances at lower operating costs, they generally give you more bang for your buck.

Rotary wings are helicopters and other such aircraft that fly with rotating blades. They’re a new and exciting way to see new sights because they’re versatile. You can land in excluded and exotic locations more easily in a rotary wing than a fixed wing. And, because helicopters can hover, they can fly through turbulence when a fixed wing would be grounded. While rotary wings are generally the more tumultuous method of flying and therefore not a great idea for those prone to motion sickness, advancements in rotary wing technology have decreased vibrations and excess noise, leveling the comfort difference between fixed wing and rotary wing.

Ultimately, it’s up to you to decide how you want to fly. There are pros and cons to each, and researching your options is the best way to go. But, whatever you decide, rest assured that ASAP Buying has your back.

ASAP Buying, owned and operated by ASAP Semiconductor, is a leading supplier of new and obsolete and hard-to-find parts and components for the aerospace and aviation industries. Fixed wing or rotary wing, we have everything you’d need to maintain or repair your aircraft. For more information or a quote, visit us at www.asapbuying.com or call us at +1-509-449-7700.

In recent years, there’s been an increase in flight and aviation across the board. People are flying more than ever. They’re also owning their own private aircraft more than ever. But before purchasing, it’s important to understand what kind of aircraft to choose. A fixed-wing or a rotary wing? What’s the difference? Well, the biggest difference is in the way they can fly.

A fixed-wing aircraft is generally an airplane. It can also be a paraglider or a hang glider, as these also have immobile wings that use forward airspeed to generate lift. In powered fixed-wing aircraft, the thrust from the propeller or a jet engine is what moves the aircraft. Because fixed-wing aircraft require air moving over their wings to generate lift and be airborne, they are must stay in a constant forward motion and cannot hover stationary.

A rotary wing aircraft is typically a helicopter, autogyro, or any other aircraft with rotary wings, or rotor blades. Rotary wing aircraft use these rotary wings to revolve around a rotor to lift the aircraft and maintain flight. As opposed to fixed-wing aircraft, rotary wing aircraft do not need constant airflow over the blades and rely on constant movement of the rotary wings to generate the required airflow over their airfoil to generate lift. They do not need to stay in constant forward motion and can hover stationary.

Other than these major differences, a fixed-wing and a rotary wing aircraft do not differ all the much. The same principles govern the physics and motion of both. Ultimately, choosing between the two comes down to personal preference. What do you want out of an aircraft? If you want to relax a bit more during flight, an airplane might suit your tastes a bit better. Of course, choosing between the two doesn’t mean that you’re only ever limited to one or the other. If you’re enthusiastic about flying, you’ll want to own and fly both. You’ll also want to maintain both.

Other than choosing which aircraft to buy and fly, it’s important to be able to repair and maintain your aircraft and know what you need. Fortunately, there’s us at ASAP Buying. Owned and operated by ASAP Semiconductor, we’re a leading supplier of all aviation parts and we’d be delighted to help you find the aviation parts you need.

Have you ever looked up and noticed those long, white streaks across the blue sky? Those are vapor trails caused by jet engines. Jet engines burn fuel using the air, releasing energy and powering the plane; this is a process called combustion. These engines are sometimes referred to as gas turbines because they bring fuel in through a windmill-like wheel, also known as a turbine, and expel hot gas.

Jet engines are similar to car engines in that they both burn fuel to release energy that powers them. There are three specific things that allow a jet engine to be more powerful than your car’s engine though:

  1. The law of conservation of energy – If a jet engine needs to make more power, it needs to burn more fuel. Jet engines are designed to burn large amounts of fuel by pulling in massive amounts of air (the ratio is about 50 to 1).
  2. Jet engines are always in maximum power mode because the intake, compression, combustion and exhaust all work synchronously.
  3. Jet engines pass the exhaust through multiple turbine stages, extracting the maximum amount of energy (piston engines only use one).

All jet engines work in the same fashion (pulling air in, combusting with fuel, and expelling exhaust) however there are six different types based on their featured components:

  1. Turbojet –good for small, low-speed jets
  2. Turboshaft –exhaust gas produces little thrust; found in helicopters, trains, boats and tanks
  3. Turbofan (low-bypass)
  4. Turbofan (high-bypass)
  5. Ramjet/Scramjet –ramjets are suitable for supersonic and hypersonic speeds (used on rocket and missile engines); scramjets can go even faster because they remain supersonic
  6. Turboprop –most of thrust comes from propellers, which are mounted on the front and push the plane upward

Listed below are quick over views of 6 key components of a modern aircraft. The components mentioned in this article will be the wings, empennage, powerplant, landing gear, aircraft frame and fuselage. All of which are extremely important in making sure that the aircraft flies properly.

Wings

As most people know, the wings are the key component in keeping any aircraft airborne. They provide a place for lift that propels the plane upwards. Wings can be fashioned to the side of the plane in multiple areas, either high up or a bit lower down on the body. At the base of each wing is a small section that can be controlled by the pilot, called the flaps. These flaps can be moved and positioned in flight, takeoff and landing.

Fuselage

This is the main body of the aircraft where you would sit when flying in a plane.

Powerplant

This section of the plane, as the name would suggest, houses the components of the plane that power it. This is where the engine lives.

Aircraft Frame

The frame, or base, of an airplane can be made of several different things, each with their own perks and benefits. Some frames allow for more pressure to be applied, some are extremely aerodynamic and others offer the builder extra support.

Empennage

This not only holds the plane steady but also allows the pilot to steer and direct the plane from the cockpit by controlling parts of the empennage such as the rudders.

Landing Gear

This aspect of the plane can differ quite a bit plane to plane. While on one aircraft the landing gear could be referring to wheels, on another the landing gear could be made up of long ski’s to allow the plane to instead land on water.

An aircraft propeller is more complex than an individual would think. Surprisingly, propellers do not exist solely to move aircrafts, they have outside uses. There are several different types of aircraft propellers all varying in design and material. This article will discuss the similarities and differences between all the different propellers the world has to offer.

First, we will review Fixed Pitch Propellers. Fixed Pitch Propellers are made solely from one piece of material; therefore, the blade pitch cannot be changed. Fixed pitch propellers are typically made from either metal or wood. Wooden propellers were mainly used for every single aircraft made before world war two. Although the wooden propellers look as though they are carved from one piece of wood, they are composed of 5 different pieces of wood laminated together. Wooden propellers are not as popular as they once were because the world has shifted towards metal propellers. Metal propellers were created many years ago and were originally used for military application. In the modern world, metal propellers are they primary choice for most aircrafts. Metal propellers are made from a single piece of aluminum alloy and therefore, have the ability and strength to last longer.

Ground Adjustable Propellers are the second class of propellers we will review. This type of propeller is ground adjustable meaning, the blade pitches can be fine-tuned and switched out with ease. This type of propeller can compensate for all different types of weather conditions and is safe for different flight altitudes. These propellers are most common on commercial aircrafts. Other important propellers include: controllable pitch, constant speed, two positions, reversing and full feathering. Each propeller has a different specialty making each choice highly specific.

ASAP Buying has a dedicated and expansive array of fixed pitch, ground adjustable and constant speed propellers, making us the premier supplier of aircraft propeller components. We serve customers as a one-stop shop and primary destination for product sourcing. ASAP Buying will ensure that your needs are addressed in the most expeditious and transparent manner, all the while offering cost-effective component solutions.

In recent times, it is not very common to hear about Original Equipment Manufacturers (OEM) producing doubts over aircraft parts safety produced by companies complying to a FAA-issued Parts Manufacturing Approval (PMA). In the past, there was a time when OEMs looked down on PMA parts produced to compete with their products. Their comments usually focused on safety claims and abuse of OEM warranties.

Due to the request made by OEMs, the FAA and EASA went through a lengthy investigation into these safety claims in 2008. The investigation revealed that there was no evidence of PMA parts being unsafe and the investigation concluded that there were no issues with their process of approving PMA parts.

Many individuals do not understand the difference between OEM and PMA, and what makes a part “approved.” If a part is approved, this means the FAA has given a specific type of approval, whether it is for an individual item or as a part for an engine, etc. Parts in aircrafts, engines and avionics need to meet the standards of the FAA that are specific to the role of the part.

An OEM holds a “Type Certificate (TC),” and TC holders can manufacture parts under the certificate. The parts that are manufactured need to be shown, labeled and documented to meet the standards of the approval. By holding a Type Certificate, the OEM has proven that the parts work safely for the higher end product they have been produced for.

PMA parts can be produced by any individual or company that chooses to go under the process of designing and documenting an OEM part’s equivalent. There is am important process a business or person must undertake for the PMA part to be approved. First, they need to submit the design for the PMA part to the FAA to make sure it is sage and meets the requirements of regulation. Second, the hopeful PMA supplier needs to pass an FAA review of quality assurance to make sure a quality assurance system is in place and to verify the part manufactured falls under FAA design approval.
