Speed brake system for aircraft spoilers

摘要: A system for allowing automatic or overriding manual actuation of an aircraft''s spoilers as airspeed brake includes a speed lever disposed adjacent the pilot whose movement is coupled to spoiler actuator by suitable mechanical linkage and logic means which receives inputs from reverse thrust sensor, forward ground contact lever. The combines these according predetermined schedule accordingly provide deploy retract output signal electrical in turn provides another linkage. allows deployment under normal landing, abnormal refused takeoff maneuvers, retraction during any goaround landing maneuver. An embodiment each elements illustrated described coupler between actuator, lever, priority movements over those actuator.
