Device for operating landing gear of aircraft between stored and unfolded positions, has transmission unit, whose inputs and output are arranged in manner so that one of inputs provokes movement of output, when other input is fixed

摘要

The device (50) has a motor unit (22) driving an input (21) of a transmission unit (20) e.g. planetary gearset, where an output (28) of the transmission unit is cooperated with a landing gear for displacing the landing gear, during the rotation of the motor unit. Another input (23) of the transmission unit is distinct from the former input. The inputs and the output are arranged in a manner so that one of the inputs provokes a movement of the output, when the other input is fixed.
