FIELD: engines and pumps.
SUBSTANCE: solid-propellant rocket engine includes housing with rear bottom, charge, igniter, cruising mode nozzle and thrust cutoff reversal nozzles located in the area of rear bottom and covered with plugs. Plugs are locked with charge-driven piston mechanisms, and charge is provided with blind channel. Housing is made from composite material as per cocoon pattern and includes rear flange to which the compartment made in the form of a spherical segment is attached. Thrust cutoff reversal nozzles are installed on the above compartment normally to the surface of spherical segment. Cruising mode nozzle is partially buried into compartment in the form of spherical segment, and igniter is arranged in it.
EFFECT: invention allows reducing the weight of rocket engine and increasing its operating time at minimum length and easier manufacturing procedure.
