Design and Analysis of Solar Array and Flywheel Power System

The flywheel energy storage offers the advantages of much higher specific power, dee- per depth of discharge, no capacity degradation over life, shorter engineering design and analysis time and longer cycle life. It is a novel spacecraft power system instead of the traditional chemical battery. In order to analyze the feasibility, the paper researches the key design element of the fly- wheel energy storage, analyzes the effect on the general design of the spacecraft and provides the demonstration and some advice on the design of solar array and flywheel power system. Com- pared with the traditional power system, the photovoltaic-flywheel power system can improve the specific power and decrease the weight and cost of the spacecraft. The solar array and flywheel power system shows great promise for future application in space.
