SPACECRAFT LAUNCH UNIT

摘要

FIELD: astronautics.;SUBSTANCE: invention relates to space engineering, particularly, to spacecraft (SC) launching units. Spacecraft launching unit consists of a hollow truncated cone of a power shell (PS) with a lower and an upper frames and a spacecraft adapter. There are duplicated heat pipes (HP) consisting of evaporator and condenser. Evaporator has thermal contact with cooled instrument arranged on separate bracket, and corresponding capacitor - with heat-conducting surface of power shell for on-board equipment (BE) located inside launching unit. Capacitor can be made in the form of self-contained radiator-cooler with formation of thermal contact between capacitors of HP for BE, located outside of launching unit. On the lower frame there is a bottom screen with heat-resistant pads. Upper screen made of heat-insulating material is installed on the upper frame. Power shell with heat-insulating material, upper and bottom shields form closed heat circuit.;EFFECT: reduced weight and increased survivability of spacecraft.;1 cl, 6 dwg
