摘要
固体燃料冲压发动机由于结构紧凑、能量高、工作性能稳定 ,可广泛应用于中、小口径弹药的增程和提高续航速度或攻击速度 ,本文建立该类发动机的燃烧室流动模型并给出了求解方法 ,得出了突扩燃烧室流动特性与突扩面积比、入口气流速度等因素的变化规律 。
Because of its compact structure, high energy and steady working properties, solid fuel ram-jets (SFRJ) are widely used to enhance the distance, prolong the sustenance and raise the attack velocity for medium or small diameter ammunitions. The paper built up models for the flow principle of combustion for such ramjets, and developed approaches to the solution of the models. Effects of sudden-expansion ratio, inlet velocity of gas, etc, on the flow properties were discussed.
