固体火箭发动机与等离子体发动机技术的结合是一个新的有价值的研究领域,国外在利用固体推进剂取代等离子推力器中的惰性材料来提高发动机推力方面的研究已经起步,并得到了提高推力及推力功率比的试验证据。介绍了国外等离子推进技术以及新型脉冲等离子发动机的结构和试验装置,讨论了该发动机的试验条件和试验结果。
The combination of solid rocket motor and plasma engine technology is a new and valuable research field. The overseas research on improving engine thrust by using solid propellant instead of inert material in plasma thruster has been started, and the improvement of thrust and Thrust power ratio test evidence. The foreign plasma propulsion technology and the structure and test device of a new pulse plasma engine are introduced. The test conditions and test results of the engine are discussed.
