Abstract
In order to improve the energy efficiency of solid rocket motors, a pulse separation device (PSD) with plug-in board and plug as the main structure is designed. This device is different from the traditional PSD, in which the material for plug-in board is tungsten infiltration of cooper and the plug is Polyoxymethylene(POM) or Polycaprolactam (MC). PSD achieves separation of the combustion chamber of the motor with its simple construction. The bursting pressure of plugs of different materials are tested by the hydraulic test, and the results are in good agreement with theoretical calculations. POM and MC can withstand pressure above 20MPa and open smoothly during the two-pulse operation. The bursting pressure of POM is 39.8MPa. The test results prove that PSD is feasible and has excellent reliability in double-pulse solid rocket motor.
