摘　　要：介绍了以NH3为推进剂的小功率电弧加热式发动机模拟空间环境的地面试验,测量了发动机工作性能参数。通过对工作参数优化,达到发动机高比冲的工作状态,并重点分析了推进剂流量对发动机性能的影响。研究结论为N2H4推进剂的试验提供了依据。The ground experiment on low power arcjet thrusters was introduced. NH3 was chosen as propellant and experiments were carried out. The thruster performance parameters were measured. High thruster specific impulse can be obtained by means of optimizing working parameters. The experimental results for mass flow are given in detail.
