Abstract: The invention provides a momentum wheel energy storage device for a spacecraft or satellite. The device has six wheels whose axes of rotation are parallel to edges of a tetrahedron. It thus provides redundancy which makes it possible simultaneously to store energy and to generate an arbitrary net angular momentum, even in the event of one of the wheels failing. The failure of one wheel can be accommodated without degrading operation, with energy storage being optimal regardless of the angular momentum to be generated. The failure of two wheels can be accommodated but operation may then be in degraded mode. The invention makes it possible to limit the number of momentum wheels used in a device that can accommodate failures.

Abstract: PROBLEM TO BE SOLVED: To provide a collecting device for solar energy for a space ship which can reduce a risk of a primary and a secondary electrostatic discharge. SOLUTION: The present invention relates to a device which can reduce the risk of the primary and the secondary electrostatic discharge occurring particularly on a solar power generating device of a spaceship. The present invention relates to the collecting device of the solar energy for the space ship which is provided with at least one reflecting plate 12 for reflecting a solar radiation 16 to at least one photocell 14 for converting the solar energy to an electric energy. According to the present invention, this device is provided with heat transport means 23, 24 and 25 which can transport a thermal energy accumulated by the cell to a low-temperature zone 22 after receiving the sunlight. The present invention is applied particularly to a solar battery panel for a satellite. COPYRIGHT: (C)2003,JPO

Abstract: A solar panel (3) having a front face (31) for receiving solar radiation and a rear face (32), for use in a spacecraft (1). The solar panel is covered on the rear face (32) with a coating (4) having negative electric charge emissive property such that in use the coating expels electrons out of the rear face (32) of the solar panel (3), thus reducing the potential difference between the front face (31) and the rear face (32). A method of reducing potential difference between the front face (31) and the rear face (32) of the solar panel (3) by covering the rear face by said coating (4).

Abstract: The solar collector has a reflector (12) directing solar radiation onto a photovoltaic cell (14). Heat is removed (23,25) from the photovoltaic cell to a cold zone (22). The heat removal uses capillary heat transfer. A plate (25) connects the base of a cell to the base of another cell. A thermally conductive insulator reduces the temperature gradient in the heat transport.
