Title: ACTUATOR SYSTEM FOR AEROSPACE CONTROLS AND FUNCTIONS
Abstract:
The present invention provides an actuator system (10, 100, 200) for use in an aircraft control or operating system, comprising control means (12) operable in response to an input for generating a control signal, and an electrical actuator (20) responsive to the control signal for operating an aircraft flight control surface or other aircraft apparatus. Means (24; 124) for aerodynamically assisting the electrical actuator are also provided in order to reduce the load on the electrical actuator in use.
