Auxiliary Equipment

A mechanically‐fired, cartridge‐actuated thruster has been developed by the Propellex Chemical Division of Chromalloy Corp., P.O. Box 187A, Edwardsville, III., U.S.A. Developed for use in the scat ejection system of the North American A3J Vigilante the thruster incorporates special spherical bearings at each end to permit three degrees of rotation during its stroke. Safety‐locked in its normal, closed position, it locks again when extended after firing.
