【Abstract】 The ignition and combustion characteristics of pasty propellant are important parameters for the motor design. An experimental study on the pasty propellant named PEPA/AP was carried out. The results show that the autoignition temperature of this propellant is about 150℃, so it is easy to ignite. As the chamber pressure is greater than 0.6MPa, the critical combustion diameter is less than 1mm. As the test motor is in operation, its propellant burning rate accords with the static burning rate. It is predicted that the propellant will be suitable for multiplestart motor.更多还原
