METHOD OF LAUNCH OF LAUNCH VEHICLE PROVIDED WITH MULTI-NOZZLE ENGINE PLANT AND ROCKET COMPLEX FOR REALIZATION OF THIS METHOD (VERSIONS) Russian patent published in 2002 - IPC

FIELD: rocketry and space engineering; launch systems for launch vehicles. SUBSTANCE: during launch of launch vehicles, gases from its engine plant are transferred through opening and are discharged by means of multi-slope chutes. Side walls of opening are mounted beyond boundaries of supersonic section of engine plant jets; provision is made for isolation of separate jets at area where they get in contact with chute surfaces. According to one version, use is made of double-slope chute with separating rib in plane of symmetry of peripheral groups of nozzles of engine plant. Hole for draining central jet of engine plant is provided at point of intersection of axis of symmetry of central group of nozzles with above-mentioned rib. According to another version, chute located under central group of nozzles of engine plant is provided with groove. Generatrices of chute and groove surfaces are located in plane of symmetry of launch vehicle. EFFECT: reduction of acoustic loads; low cost of rocket complex; increased mass of payload being injected. 4 cl, 3 dwg
