Abstract: A power system provides various levels of electrical power at various radio frequencies to specific input locations of a neutral particle beam accelerator system. Both the power system and the accelerator system are mounted on a space platform. The power system includes separate modules mounted on two hinged members of the platform. The modules utilize turbines, generators and fuel cells to provide the needed electrical power which is amplified to the desired levels required by the accelerator system. In addition, a fuel cell is utilized to power a pulse drive motor to drive the generators during turbine start up in order to provide high voltage output power during the start up. A regenerator produces hydrogen and oxygen from the water effluent produced by the fuel cells and the combustors which powers the turbines thereby recycling the fuel and working fluid and consequently making the power system generally non-contaminating and fuel efficient.

Abstract: A photovoltaic electric power system for use in space. A self contained sun powered electric power generating system comprising a fresnel mirror array made up of a plurality of quadrilateral mirrors individually mounted on a generally flat supporting structure with the mirrors aimed at a common point above the structure, a photovoltaic array positioned at the common point by a movable strut mechanism, heat exchanger means at the PV array to draw excess heat therefrom, coolant lines from the heat exchanger means running through the struts to transfer heat to heat pipes configured as flat panels at the edges of and perpendicular to the supporting structure, and positioning means attached to a separate structure to enable the system to track the sun. The system is designed to fold into itself in the form of an elongate box for launch, maneuvering and protection.

Abstract: A heat pipe radiator coating of a fibrous material provides protection for the radiator, such as a heat pipe, pumped loop, etc., while allowing good emissivity and heat rejection. Fibers are constructed from fiberglass, glass, quartz, saphire, diamond, carbon carbon, tantalum, stainless steel, aluminum, beryllium, and copper, and may be coated with a variety of metallic materials.
