FIELD: engines and pumps.
SUBSTANCE: rocket engine includes housing that consists of rear cover with nozzle cluster and nozzle closure, fuel charge located in the housing and equipped with compression mechanism. Compression mechanism represents a piston installed in engine housing at nozzle cluster side and gas source communicating with cavity between piston and nozzle closure. Piston is performed in a form of hollow cylinder with sealing rings at side surface and openings at the ends closed by membranes. Gas source represents pyro cartridge with balloon located outside at housing rear cover near nozzle critical cross-section. Membranes are mostly made of copper foil.
EFFECT: invention allows safety improvement of paste fuel engine, decrease of its mass.
