  1. The experimental results indicates that the secondary mass flow increases with increasing of primary mass flow rate, but the bypass decrease because the primary mass flow rate increase more rapidly than secondary mass flow. the expansion configuration shows low thrust property due to low pressure in flow path. the secondary nozzle changes the pressure distribution in ejector combustor, and decreases bypass ratio, but obtain more completely mixing

    結果表明:二次流流量隨著一次流流量的增加而增加,由於二次流流量的增加速度低於一次流,引射系數減小;在純擴張式結構實驗中,引射燃燒室壓強很低,難以實驗推力增強;二次改變了引射燃燒室的壓強分佈,降低了引射系數,改善了混合況能;對于本文的實驗結構,存在一個最優的二次面積,使引射箭推力最大,同數值模擬結果相吻合。
