Aircraft are large vehicles with numerous heavy control surfaces and flight systems that are paramount to standard operations. To ensure proper control over the aircraft during flight, pilots must have a means of quickly activating and managing various airplane parts. With aircraft actuation systems, energy can be harnessed from mechanical sources to create linear or rotary motion for the means of operating landing gear, flaps, aircraft brakes, slats, and much more. While many early aircraft took advantage of cables, gears, and rods for mechanical actuation, new systems have come about over the years which are more streamlined and efficient. In this blog, we will discuss the various types of aircraft actuation systems that are commonly present in the aviation sector, allowing you to best understand their functionalities and design.
