Описание материала

To achieve higher performance of pulsed plasma thruster (PPT), laboratory model of breech-fed type, which has high energy transfer efficiency, has been designed and built. In addition, in order to understand key factors to increase performance, effects of electrode geometries, electrode’s width and gap, on impulse bit, specific impulse, thrust efficiency were investigated. As a result, it was clarified that the electrode geometry strongly affected on not only impulse bit, specific impulse, and thrust efficiency but also discharge waveform which affects impulse bit, capacitor temperature and its lifetime. 27 % of thrust efficiency, which was highest in this study, was achieved with 50 J of input energy.
