Abstract

A self contained failure tolerant linear drive mechanism that is especially adapted for celestial space applications. First and second motors are concentrically connected to a shaft for axial movement through rotation of either or both of the motors. A locking mechanism having failure tolerant releasing means cooperates with each motor to provide for selective actuation of either motor and predetermined axial movement of the shaft.
