| Abstract: | A kind of pneumatic gas control valve was investigated.The mathematical model and simulation model for the gas generator and pneumatic gas control valve of solid ducted rockets were established.Moreover the model of gas control valve was verified in tests,with the dynamic error and the steady-state error within 5 %.Finally the dynamic response performance of the gas generator and gas control valve were obtained through simulation.The simulation results show that the gas adjusting system open-loop responses slowly with strong nonlinearity. |
