LINEAR ACTUATOR WITH SPEED CONTROLLING BRAKE

摘要

An actuator suitable for use as an ejection jack (10) for deploying an aircraft mounted ram air turbine (118) is provided. The actuator includes a force transmitting reciprocating member (12) mounted for reciprocating movement along a path (18), and a centrifugally actuated brake (34) operatively connected to the reciprocating member (12) in a manner to be driven by and to limit the speed of the reciprocating movement of the reciprocating member (12) along the path (18).
