Analysis and improvement of characteristics of power supply systems for the small space vehicle of the AIST-2 type

Abstract

The power supply system being created is intended to provide electricity to spacecraft systems. It ensures that the design characteristics of the solar battery of the prototype are preserved and makes it possible to install means to support the thermal conditions of the photovoltaic battery while maintaining the cost of production of the prototype solar battery. Various types of solar energy concentrators are considered: concentrators in the form of individual convex linear Fresnel lenses, Flexible Array Concentrator Technology concentrators, Stretched Lens Array concentrators. A method for improving the characteristics of the spacecraft solar system is presented. The methodology includes the calculation of various types of concentrators, types of photovoltaic converters and types of solar battery frames. As an example of the implementation of the methodology, the design of solar battery panels was developed. A comparative table of the solar battery before and after modernization is provided.
