摘要
针对目前理论模型多注重可行性和影响因素分析,以及方程复杂求解困难的现状,为了得到一个应用性较强的涡流阀变推力发动机推力工程计算方法,借鉴普通固发求解推力原理,结合数值模拟方法,建立了涡流阀变推力发动机的整体模型。结果表明,该模型有一定的精度,模型计算参数与试验和前期理论分析趋势一致,模型简洁并包含主要设计参数,可满足涡流阀变推力发动机的设计需要。
In order to solve the problem that most theoretical models focus on feasibility and effect factors analysis,a compact thrust calculation method of variable thrust SRM controlled by vortex valve was put forward.The calculation results obtained by the model agree well with test results.The model is simple and involves main design parameters,which satisfy the design requirement for variable thrust SRM controlled by vortex valve.
