Abstract: Technical project and experiment results of multiple-start and shutoff of hybrid propellant motor (called hybrid motor for short below) were presented. The performance data of hybrid motor were measured. Various kinds of factors, which affect hybrid motor performance, were preliminarily analyzed. The experiments show that multiple-start and shutoff can be realized and its number of times and time intervals can be regulated at ramdom.

Key words: Hybrid rocket;Ignition;Hypergolic ignition;Shutoff~+
