摘　　要：采用再生冷却技术设计了一种新型电弧加热发动机。介绍了发动机的本体结构、实验系统、参数测量系统及小推力测量系统。采用氩为推进剂,在真空室中进行了发动机的性能实验。电弧加热发动机的比冲大约为1372～1764m/s,其比冲随流量的增大而减小,随功率的增大而增加;发动机效率大约为30%～57%,其效率随流量的增大而增大,随功率的增大而减小。A new arcjet was designed with regenerative cooling.The structure of arcjet,experimental system,measurement system and the small thrust measurement system were introduced.The performance experiment of arcjet was made in vacuum chamber and argon was chosen as the propellant.The specific impulse of arcjet is about 1 372～1 764 m/s.The specific impulse decreases with the increasing of flow rate and increases with the increasing of power.The efficiency of the arcjet is about 30%~57% and it increases with the inc...
