Abstract: A rocket motor structure which includes a head closure and an aft section th a multiplicity of composite tubes mounted therebetween to define a multiplicity of small chambers for providing an overall rocket motor and in which the aft section includes a nozzle structure for the composite tubes and provides attached fins for guiding and stabilizing the structure. Also, the nozzle structure can be provided with an igniter mounted in the nozzle.

Abstract: A high efficiency propulsion system for launching a rocket or projectile h higher delivered specific impulse than can be delivered with a given propellant using a conventional rocket or recoilless gun and still maintain a recoilless launch condition.

Abstract: A rocket engagement mechanism that will enable a gunner to pre-aim and then emotely fire the rocket while the gunner is hidden. The gunner is physically separated from the noise and smoke resulting from firing a rocket thus giving the gunner a better chance to escape the resulting return fire. The mechanism can also be used as a booby trap device that can be left by retreating troops to harass and slow the enemy advance. A cap is attached over the firing mechanism of the rocket launcher and has a piston squib positioned to press the launcher firing mechanism when the squib receives an electrical signal.

Abstract: A hypervelocity rocket system with velocity amplifier including a launch e with a projectile mounted therein by sabot means and a rocket motor with an energy absorber at one end and mounted in the launch tube for impacting the projectile and causing velocity amplification of the projectile through momentum transfer as it is propelled from the launch tube.

Abstract: A man transportable rocket launcher including a pair of telescoping secti, launch tubes, which are telescoped when being transported and extended for launching of the rocket. The warhead of the rocket always rides on the inner surface of the front tube which is carried inside the rear tube. Retention means cooperate with the fins to assist in retaining the rocket fins in folded position in the launcher prior to rocket launch. The retention means is moveable, with the rocket in the rear tube, for a predetermined length of travel of the rocket at which time the fins are released by the retention means and engaged by the inner surface of the front tube.
