SYSTEM FOR INJECTION OF SPACECRAFT

摘要

FIELD: rocketry and space engineering; injection of spacecraft into preset orbits. ^ SUBSTANCE: proposed system includes launch vehicle coupled with cryogenic stage and cryogenic stage proper. Cruise engine of cryogenic stage has nozzle attachment at high degree of expansion which is sunken in central part of compartment of launch vehicle stage coupled with cryogenic stage. Elongation of nozzle attachment of cruise engine and degree of its expansion depend on space of central part of adapter compartment of launch vehicle. Nozzle attachment at increased degree of expansion at shear has increased diameter. Gimbal of cruise engine combustion chamber is provided with stop for impactless escape of nozzle attachment from cavity of adapter compartment of launch vehicle coupled with cryogenic stage; this stop is used for limiting the deviation of combustion chamber through angle required for control of cryogenic stage motion and ensuring the guaranteed clearances between nozzle attachment and mounting equipment. ^ EFFECT: increased mass of payload due to increased specific pulse of cruise engine. ^ 2 dwg
