An experiment system of powdered rocket motor was established to investigate some key technologies, such as multi?ple start?ups and thrust regulation and so on, large numbers of experiments were conducted. The results indicat that under the effect of high energy spark plug,powered rocket motor can realize multiple start?ups and shutdown.Moreover startup and shutdown times, the time intervals can be regulated randomly. By adjusting the flow rate of the powder fuel and oxidant, powered rocket motor can a?chieve thrust control technology,and thrust regulation ratio reaches 6.5.
