摘要

1. Akira Kakami, Shinji Beppu, Muneyuki Maiguma and Takeshi Tachibana: Thrust Evaluation of an Arcjet Thruster Using Dimethyl Ether as Propellant. No. 684, p. 1 (Jan.) The present paper describes performance evaluation of a Dimethyl Ether (DME) propellant arcjet thruster. We have proposed to apply DME to arcjet thrusters owing to its favorable characteristics for space propulsion device such as non toxicity, weak chemical reactivity and storability. Thrust measurement using a vertical-pendulum-type thrust stand showed that thrust was almost monotonously increased with mass flow rate at a given discharge current, and rose with specific power. Specific impulse was also enhanced with specific power whereas thruster efficiency was attenuated. DME propellant presented higher thrust, specific power and thruster efficiency than nitrogen propellant at a given discharge current or specific power. Thrust measurement yielded a thrust of 0.19N, a specific impulse of 330 s, thruster efficiency of 0.14 at a DME flow rate of 60-mg/s with the corresponding discharge voltage, power, and specific power of 90 V, 2350 W, and 39MJ/kg, respectively.

Akami Kakami，Shinji Beppu，Muneyuki Maiguma和Takeshi Tachibana：使用二甲醚作为推进剂的Arcjet推进器推力评估。第684页，第243页。 1月1日。本文描述了二甲醚（DME）推进剂电弧喷射推进器的性能评估。我们建议将DME应用于电弧喷射推进器，因为它对空间推进装置具有良好的特性，例如无毒，化学反应性和存储性差。使用垂直摆式推力架进行推力测量显示，在给定的放电电流下，推力几乎随质量流量单调增加，而随比功率的增加而增加。比冲也随着比功率的增加而增强，而推进器的效率却降低了。在给定的放电电流或特定功率下，DME推进剂比氮气推进剂具有更高的推力，比功率和推进器效率。推力测量产生的推力为0.19N，比脉冲为330 s，在DME流速为60-mg / s时推力效率为0.14，相应的放电电压，功率和比功率分别为90 V，2350 W和39MJ / kg。
