The architecture of an aircraft is extremely dynamic, with several components moving in unison to produce stable and comfortable flight. Any devices involved in the aircraft's aerodynamics are labeled as flight control surfaces, and in this category, there are many. Falling under the primary control surface category are elements such as the ailerons, elevators, and rudder. Meanwhile, secondary control surfaces include spoilers, slats, and air brakes. While each of these aerodynamic devices plays a critical role in facilitating flight, this blog will focus on flaps, which serve several objectives and come in a variety of designs.
