【摘要】 研究了一种气动式的燃气流量调节阀,并建立了固体火箭冲压发动机燃气发生器和气动式燃气流量调节阀的数学模型及仿真模型,对燃气流量调节阀仿真模型进行了试验验证,动态误差和稳态误差都在5%以内。通过仿真获得了燃气发生器和燃气调节阀的动态响应特性。仿真结果表明,燃气调节系统开环响应速度较慢,并具有很强的非线性。更多还原

【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.更多还原
