英文摘要： The study on discharge characteristics generated by hypervelocity impact solar array with power, involving in material dynamics, impact dynamics, condensed state physics and other fields, has an important application value in the field of protection solar array from space debris. This project takes solar array with power as the research object, systemtic research on discharge characteristics created by hypervelocity impact solar array with power through the experimental study and theoretical analysis. The key points are placed on the establishments of the external circuit power supplying system， discharge measurement system and the diagnostic system for plasma characteristic parameters . Change rules of discharge voltage and current with impact parameters generated by hypervelocity impact solar array can be obtained under given supplying power and different impact parameters through the external circuit power supplying system and discharge measurement system,meanwhile, Critical impact velocity of hypervelocity impact solar array with power can be determined. Plasma characteristic parameters created by hypervelocity impact solar array can be obtained by using Langmuir probe diagnostic system. Fourthermore,temporal and spatial distribution theoretical model of plasma characteristic parameters can be established. Temperature field near collision point would be recombined by ultra high speed camera to take experimental photos, and using image processing technique of double color measurement temperature methods. Discharge characteristics of plasma generated by hypervelocity impact solar array with power can be revealed .All these research production will Provide a valuable references for condensed matter physics, impact dynamics and protection solar array from space debris.
