Engineering model design of electrical power subsystem for the Space Flyer Unit
Abstract
The Space Flyer Unit (SFU) is an unmanned, automated, and reusable space platform. The development of the SFU has entered on its engineering model phase. Its electrical power subsystem has four batteries consisting of 19AH Ni-Cd cells to supply 1.4kW power to all subsystems and experiment payloads during eclipse. As a result of thermal analysis, it is predicted that the temperature of shunt dissipators rises up to 70 C and cools down to 40 C. Retrieval by the space transportation system is the highest priority mission of the SFU, so that the reliability and safety design should be the most important matter. In this paper an EM design of the electrical power subsystem from the point of view described above is presented.
