A New-type Pyrotechnics Separation Device Based on Throttle and Pressure Relief Structure

Based on analysis of separation failure of a rocket projectile during research and development process,the structure of pyrotechnic separation device was improved,throttle and pressure relief structure was designed and set in the device. The verification test results indicated that the new-type pyrotechnic separation device can reduce the value of ignition pressure peak about 65%,and realize accurate control of the value. The new structure meet with the requirement of separation velocity as well as impact overload. Finally,the effective method has been applied successfully for the rocket projectile. Through adjusting parameters of throttle and pressure relief,the improved structure can be applied to separation of different rocket projectile.
