SPACE VEHICLE LAYOUT DESIGN METHOD Russian patent published in 2009 - IPC B64G1/50 B64G1/22 

FIELD: transportation.

SUBSTANCE: said utility invention relates mainly to telecommunication satellites with long service life. The method involves designing a space vehicle of two modules, a support system module and a payload module. The module radiators are made of triple-layer honeycomb panels with heat tubes integrated into them. These radiators are located in planes normal to the +Z and -Z axes of the vehicle (at its "northern" and "southern" sides). Module instruments are installed on the outer surfaces of the inner shells of the radiator panels and on the surfaces of the triple-layer honeycomb instrument panels located between the said radiator panels. The latter are equipped with manifolds for the heat medium circulation, which are connected to the similar manifolds integrated in the instrument panels so that both manifolds form closed circulation circuits. The manifolds of the said radiators are installed on the outer surfaces of the inner shells of the honeycomb radiator panels, opposite to the evaporation zones of the heat tube integrated in these panels. The condensation zones of these heat tubes are located parallel to the +Y or -Y axes of the vehicle (the "eastern" and "western" directions). The evaporation zones of the heat tubes are located in parallel to the longitudinal axis +X of the vehicle. A safety shield is installed above each manifold of the said radiators.

EFFECT: decreased radiator weight (by 3 % minimum) with these types of heat tubes, manifolds, and honeycomb panel structure.
