SPACECRAFT AND SECTION OF PHASED ANTENNA ARRAY Russian patent published in 2008 - IPC B64G1/22 H01Q1/28 H01Q3/30 

FIELD: transport.

SUBSTANCE: spacecraft includes the phased antenna array (PHAA) representing flat rectangular sections, each of them the structures furnished with a front covering fitted on the carcass. The spacecraft onboard equipment is fixed on the rear sides of the flat hardware platforms arranged at the PHAA sections rear. In placing the spacecraft into orbit, the PHAA sections are folded with their faces parallel to each other, with solar batteries panels being inserted there between. Transceiver units are arranged on the front covering rear with their radiator on the covering face. Thermal pipes are arranged inside the front covering and connected with the device of heat withdrawal into space. The suggested PHAA section contains a carcass, the a front skin, a transceiver units and radiators. The section carcass is made up of rectangular closed section channels furnished with an extra internal strip. The front covering made up of three-layer panels is attached to the said strip. A screen-vacuum heat-insulation layer is arranged between the aforesaid panels. The outer panel is made from carbon-based plastic material, the inner panel is made from aluminum alloy. The inner panel honeycomb structure accommodates heat pipes withdrawing heat from the transceiver units.

EFFECT: high geometrical stability of the phased antenna array, smaller weight.
