Abstract:

A control tab on a submarine or the like is angularly displaced by a remote control actuator system featuring a pair of shape-memory cables consisting of a superelastic actuating cable connected to the control tab and a force generating thermoelastic cable anchored to the submarine frame. A force transmitting lever interconnects the cables and is selectively locked by a releasable locking mechanism in a position holding the actuating cable fully stretched with the control tab displaced a maximum amount from its neutral position by the displacing force generated in the thermoelastic cable in response to heating thereof by electric current conducted therethrough.
