control for primary flight control system with vibrationsmotor

摘要

The invention provides an actuator for a control surface ( 7 ), in particular for a primary flight control of an aircraft, the actuator including a main actuator ( 3 ) in a main control line ( 1 ) for actuating the control surface ( 7 ), the actuator being characterized in that the actuator of the main control line ( 1 ) comprises a motor of the vibration motor type, and in that it further comprises, in a compensation, secondary control line ( 2 ), a compensation actuator ( 4 ) and spring-forming apparatus ( 5 ) interposed between the compensation actuator ( 4 ) and the control surface ( 7 ), the compensation actuator ( 4 ) tensioning or compressing the spring-forming apparatus so as to make them suitable for delivering a mean force to the control surface ( 7 ) so as to off-load from the main actuator ( 3 ) the mean force that it needs to deliver to the flight control ( 7 ).
