Research and Development of a Novel Electrodeless Plasma Rocket Engine Using a Helicon Source

新型螺旋源无极等离子火箭发动机的研究与开发

基本信息

项目摘要

Fuel cost using electric propulsion is better (specific impulse is higher) than chemical one. The contact erosion between a plasma and electrodes, producing and accelerating the plasma, leads to a lifetime shortage. To overcome this, our study had "electrodeless" conditions.Helicon sources have been developed and characterized: The largest (smallest) diameter of 74 (0.3) cm was achieved, and the scalings of the production efficiency have been established. Roles of a helicon and a TG waves were examined. We have proposed many acceleration schemes: A helicon source alone showed the maximum specific impulse of 3,000 s and the maximum ratio of thrust to power of 16 mN/kW. The excited magnetic field penetration and the ion velocity increase were found in the RMF scheme. Methods such as REF and PA/ICR were also advanced. We have developed the two-dimensional measurement systems using laser induced fluorescence and high-resolution spectroscopy, and the various types of the thrust stands.
使用电推进的燃料成本比化学燃料更好(比脉冲更高)。血浆和电极之间的接触侵蚀,产生和加速等离子体,导致终生短缺。为了克服这一点,我们的研究具有“无电”状态。已经开发和表征了helicon的来源:达到了最大(最小)的直径为74(0.3)cm,并确定了生产效率的尺度。检查了Helicon和TG波的作用。我们提出了许多加速度方案:单独的Helicon源显示3,000 s的最大比脉冲,并且推力与16 MN/kW的最大推力比。在RMF方案中发现了激发磁场渗透和离子速度的增加。 REF和PA/ICR之类的方法也被提出。我们使用激光诱导的荧光和高分辨率光谱以及各种类型的推力架开发了二维测量系统。
