Propulsion unit fireable from an enclosure

摘要

A recoilless propulsion unit fireable from an enclosure utilizes a releasably sealed multi-holed nozzle member to expel a fluid therefrom by a closed-breech type piston that is activated by a propellant charge. The propulsion unit after firing has minimum impact of overpressure, noise on both the launch crew and has no flash or smoke signature emitted therefrom.
