Abstract
This paper describes the optimization of a Cassegrainian collector/receiver system to be used in a solar-dynamic power module for a space station. After an introduction to solar-dynamic space power generation and its various alternatives of solar collectors, the Cassegrainian collector/receiver system is described in more detail, its advantages are outlined. Because a useful numeric tool for analysing the double reflector Cassegrainian collector/receiver system was not available, a computer code was developed. The code allows the variable modelling of the collector, the receiver, includes solar limb darkening effects, and offers the possibility to make realistic assumptions for collector/receiver system errors. Hence, this computer code sets the ground for real-life operation simulation. The exact knowledge of the intensity distribution in the receiver aperture plane and the receiver interior is indispensable for aperture optimization and receiver simulation and design. These intensity distributions are supplied by the computer program. Results of a sensitivity analysis are presented and discussed.
