EARTH REMOTE SOUNDING SPACECRAFT

摘要

FIELD: transport.SUBSTANCE: invention relates to spacecraft and onboard equipment design, mainly to thermostatic systems. Spacecraft integrates target hardware and service systems modules and is equipped with thermostatic jacket composed of rectangular parallelepiped. Three-layer cellular thermo panels with metal facing with heat pipes arranged there between are secured at sides of said parallelepiped. Jacket shell has a liquid heat carrier channel arranged at spacing equal that of heat pipes. Heat carrier has heat and mechanical contact with heat pipes. Channel length, heat pipe length and spacing between said pipes are selected to make jacket temperature differences along two mutually perpendicular directions not exceeding preset tolerances. One of thermo panel jacket walls composed of five-layer cellular panel allows a thermal contact between target hardware modules and service systems. Pipes of hydraulic main line are laid at thermo panel outer lining. End face thermo panel is composed of perforated metal plate for target hardware covers. Every plate hole is aligned with optical axis of appropriate hardware. End face thermo panel inner surface accommodates hydraulic main line pipes. Stable-size bearing structure (for example, of black-reinforced plastic) for target hardware is secured inside the jacket along spacecraft lengthwise axis. Service instrumentation of target hardware module is mounted at jacket top end wall. Jacket outer section is isolated from space by vacuum shield heat insulation.EFFECT: higher quality and accuracy of target data.4 dwg
