PERFORMANCE INVESTIGATION OF SPT-20M LOW POWER HALL EFFECT THRUSTER

摘要

The series of low power Hall effect thrusters (LPHT) SPT-20M was developed and manufactured in STC SPE of the National Aerospace University "KhAI". The main aim was to create a thruster with high performances: high specific impulse and the efficiency up to 40%. During SPT-20M experimental research a number of tests was made. The LPHT magnet system was investigated by taking into account construction thermal conditions. The experimental results show that final model SPT-20M6.1 has good enough performances with respect to the power consumption, which is lower than 100 W.
