Flight control surface actuation system with redundantly configured and lockable actuator assemblies

摘要

A flight control surface actuator assembly (120) includes a pair of flight control surface actuators (206, 208) and a pivot arm (212). One of the flight control surface actuators (208) is coupled to a flight control surface (202) and a static airframe structure (215), the other flight control surface actuator (206) is coupled to the flight control surface (202) and the pivot arm (212). The pivot arm (212) coupled to the static airframe structure (215) and is configured to pivot relative to the second flight control surface actuator (126) and the static airframe structure (215).
