电弧加热发动机的实验研究

EXPERIMENTAL INVESTIGATION OF ARCJET ENGINE

介绍一种低功率电弧加热发动机系统的实验研究。该系统包括电源，点火系统，推进剂供给系统，发动机本体和一些测量设备。用氮和氩对不同的喷口喉道直径（０．６ｍｍ～１ｍｍ），不同的质量流率（２０ｍｇ／ｓ～１００ｍｇ／ｓ），不同的电源电压（８０Ｖ～１５０Ｖ）进行了性能研究。所有试验都是在直径为１ｍ，长为１．

A laboratory system of low power(1 kW class)arcjet engine is described.It consists of a power supply and ignition system,propellant feeding system,engine body and some measurment devices. The performances described were acquired for different constrictor diameters(0 6～1 mm),mass flow rates(20～100 mg/s)and voltages(80～150 V)of power supply with Nitrogen and Argon.All of the tests were conducted in a 1 6 m long and 1 m in diameter vacuum chamber.
