A vacuum arc thruster was developed for 300V direct-drive operation on nano-satellite. The cone-type target was produced for improving thrust measurement in place of the plate-type target. The metal vapor velocity was measured with changing the parameter of applied voltage and amount of capacitance. The average velocity did not change in this measurement. The thrust was proportional to amount of charge stored in capacitance. The engineering model of thruster was produced and drove directly by 300V solar array in vacuum chamber. The circuit of thruster was also developed for nano-satellite.

研制了一种用于纳米卫星300V直接驱动的真空电弧推力器。为了改进推力测量，研制了锥型靶来代替板型靶。通过改变施加电压和电容量的参数来测量金属蒸气速度。在这次测量中，平均速度没有改变。推力与储存在电容中的电荷量成正比。制作了推力工程模型，并在真空室中由300V太阳能电池阵直接驱动。研制了纳米卫星的推进器电路。
