Research of a low toxicity propulsion system for space craft using HAN propellant

本课题的研究目的是将HAN基推进剂应用于空间推进器。与目前使用的肼类推进剂相比，毒性低，比冲高。通过催化剂点火、电点火和电推进，HAN基推进剂可以获得适合于轨道机动、姿态控制和轨道保持的推力和比冲。这些研究的结果表明，HAN推进剂能够在所有系统中点火。获得的点火和燃烧特性对飞行模型的设计和试验是有用的。未来，基于这些结果的推进器将被开发，并将在轨道上进行测试。

The objective of this study is application of HAN based propellant to thruster of space craft. As compared with the current propellant, Hydrazine, toxicity is low and specific impulse is high. With catalyst ignition, electric ignition, and electric propulsion, HAN based propellant can achieve the thrust and the specific impulse appropriate to maneuver the orbit, to control the attitude, and to keep the orbit As the results of these studies, HAN propellant was able to be ignited in all systems. The obtained characteristics of the ignition and the combustion are useful to design and to test a flight model. In the future, thruster based on these results will be developed, and will be tested on the orbit.
