Abstract: 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.
