FIELD: engines and pumps.
SUBSTANCE: propulsion installation includes rocket booster arranged in funnel of nozzle of cruising rocket engine, sealing assembly of nozzle of cruising rocket engine and pressurisation system of cruising rocket engine. The shell having a hole in its bottom through which the piston connected to rocket booster passes is installed in nozzle of cruising rocket engine. Cylindrical wall of the shell interacts with cams simultaneously contacting with interlocking device provided on rocket booster and either with guide cylinder fixed in nozzle of cruising rocket engine, or directly with nozzle of cruising rocket engine.
EFFECT: invention allows improving reliability of propulsion installation with separable booster solid-propellant rocket engine.
