FIELD: engines and pumps.
SUBSTANCE: solid propellant rocket engine comprises vessel, igniter, arranged in front or back part of engine, multi-nozzle unit concealed in vessel and insert charge of solid rocket propellant arranged in vessel and armoured along side surface and end. Multi-nozzle unit is arranged in front or back part of engine. Jacket made of elastic resilient material is installed tightly with interference onto charge at the side of armoured end, contacting with side armoured surface of charge, armoured end of change and engine bottom. Length of jacket makes 0.1…1.0 of length of armoured section of side surface of charge.
EFFECT: reduced smoke formation and increased reliability of solid propellant rocket engine with insert charge, due to elimination of combustion products overflow over armoured surface of charge.
