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.
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.
Flap and slat actuation
Liebherr develops and produces flap and slat actuation systems to extend the movable trailing edges and leading edge surfaces. These systems consist of a set of components that are installed along the wing trailing edge such as power control unit, geared rotary actuators, ball screw actuators, transmission shafts or position sensors. Liebherr’s capability does not only include the development and production of these components but also the system controller including hardware and software.
