ABSTRACT:
In order to provide for the releasable locking and reversible actuation of a control surface, where the control surface is normally locked but can be released in a nearly frictionless manner, the flight control system includes a shaft disposed within a shaft-receiving socket for carrying the control surface. The shaft is operatively associated with the shaft-receiving socket for rotational movement therewith which rotational movement is imparted through the shaft-receiving socket for moving the control surface by a motor or the like. Additionally, the flight control system includes an operating mechanism for releasably locking the control surface in a selected position including a detent integral with the shaft-receiving socket and also including a latch carrying a roller bearing mounted for pivotal movement of the roller bearing for locked engagement with the integral detent.
