 Arcjet-Engine Performance Test Using Hydrogen/Nitrogen Mixtures as Propellant Wu Hanji Feng Xuezhang Jiang Yuanda Zhang Zhiyuan Liu Wenxi Ma Yuli (Center for Space Science & Applied Research, Academia Sinica,Beijing 100080) 2002, 22 (04):  .  Abstract ( 1832 )   The results of Arcjet engine performance test using Hydrogen/Nitrogen mixture (with simulating the decomposition products of hydrazine) with a pulse width modulated (PWM) power source are summarized. Tests show that the PWM power source runs stably and the DHSL 1 and DHSL 2 engines can be operated under the conditions of using Hydrogen/Nitrogen mixture as propellant, but the performance obtained from tests are somewhat lower due to internal leak of the engine seals at the high temperature.
