High lift control systems are required to limit take-off and landing speeds by increasing wing high lift. This is achieved by wing leading and trailing edges extension devices.
Liebherr develops and produces slat and flap actuation systems to extend these movable wing surfaces. Such systems consist of a set of components that are installed along the wing. Liebherr’s capability also includes the development and production of the system controller including hardware and software.
High lift control systems can be driven hydraulically, electrically or with hybrid technology. For electrically driven systems that require high power electronic drives, Liebherr develops and produces special motor control units.
High lift control systems made by Liebherr are integrated into commercial airplanes, military transport aircraft, UAV as well as regional and business jets.
