摘要
概述了用自制的脉宽调制电源供电 ,以氮氢混合气 (模拟肼的分解产物 )作推进剂的电弧加热发动机性能试验的情况及初步结果。试验表明 :自制的脉宽调制电源工作稳定 ;在混合气作推进剂的情况下 ,DHSL- 1和 DHSL- 2发动机可以正常运行 ,但由于发动机的高温密封性能不好 (漏气 ) ,测得的性能数据偏小。
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.
