Abstract
An electrically-powered downlock actuation system for a landing gear that does not convert rotary motor output into linear motion during the actuation process, but instead uses the rotary motor output to directly drive a locking mechanism coupled to upper and lower landing gear braces. The electrically-powered downlock actuation system may include an electric motor, a gearbox (optional), a clutch (optional) and a fixed link to replace a hydraulically powered downlock actuation system. Further, the electrically-powered downlock actuation system may be controlled with motor control electronics that cooperate with one or more sensors arranged to detect a position of an output shaft.
