Abstract: The shuttle for launching an RPV is connected to a launching tube by a motion and high speed-multiplying pulley and cable assembly. The telescopic launching tube assembly is connected between and parallel to a pair of elongated arms of a sealed U-shaped tubular assembly connected by a manifold to which the telescopic tube and shuttle are latched back against the force of compressed air stored in the U-shaped receiver. The release of the latch is damped to minimize acceleration forces on the launched RPV. The receiver and launching tubes are mounted on an elongated base whose rear end is rotatably connected to an anchor plate and the front end of the tubular assembly is adjustably mounted upon the front of the base on an adjustable jack support.

Abstract: A rocket-powered vehicle is held latched at the starting end of its guide track while a high steam pressure is built up within the rocket casings through probes inserted into the nozzles which also seal them. When the latch is released, the rockets move off the probes to unblock the nozzles whereby the rockets propel the vehicle down the track to launch the flying device.
