SPACECRAFT Russian patent published in 2014 - IPC B64G1/00 B64G1/50 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to design and thermal control of spacecraft in weight of up to 100 kg launched as parallel payloads. Spacecraft unpressurised parallelepiped-like container has cellular panels (3, 4, 5) with instruments (2) installed threat. Heat from instruments (2) is uniformly distributed over said cellular panels by means of manifold heat pipes (6). Note here that instruments are stabilised thermally. Notable decrease in instrument heat release switches on the electric heaters at upper cellular panel (3). This allows a tolerable temperature of instruments to be ensured by cellular panel and heat pipes (6). Lower cellular panel (4) is directed towards the Earth and represents a radiator design. Upper and lower panels are interconnected by adjustable diagonal struts (8). Shield-vacuum heat insulation (9) is arranged at lateral faces of instrument container without cellular panel. Said insulation is arranged at screen structure secured at cellular panel, on inner side of solar battery panes (1).

EFFECT: decreased weight, enhanced performances on mini- and micro-spacecraft.
