Description

technical field [0001] The invention belongs to the technical field of electric propulsion systems, and in particular relates to a research method for the influence of electric propulsion plumes on solar cell arrays. Background technique [0002] As we all know, an electric thruster is a device that uses electrical energy to heat, ionize, and accelerate a working medium to generate high-speed ions, thereby generating thrust. Compared with traditional chemical thrusters, electric thrusters have the advantages of high specific impulse, long life, compact structure and light weight. In recent years, they have been widely used in deep space exploration, satellite orbit maintenance, satellite attitude control and orbit transfer. . As an important part of the spacecraft energy system, the solar array is exposed outside the cabin for a long time. The thruster plume formed when the electric thrusters of different types, functions and installation positions work and the CEX backflo...

Problems solved by technology

At present, domestic and foreign studies on the effect of plumes on solar cell arrays mainly focus on the research on the sputtering corrosion effect on the glass cover and silver interconnects, the thermal simulation of the unsuperimposed space environment, and the space filling without considering the plume plasma. In terms of discharge effect research, with the continuous development of solar cell array development technology, the continuous superposition of space environment and plume effects, and the continuous expansion of the application of new materials on the surface of solar cell arrays, the original research methods will not meet the needs of solar cell arrays. development needs
