Actuator for aircraft stabilizers with a failure responsive lock control mechanism

摘要

A horizontal stabilizer actuator (10) for a winged aircraft which is selectively pivotally controlled by a pilot or operator at a remote location in the aircraft and which has a primary load path responsive to the selective control by the pilot or operator for setting the pivoted position of the stabilizer and which has a secondary load path which is responsive to a failure in the primary load path to be automatically actuated to a condition locking the stabilizer in a fixed position.
