摘要
建立了超声速环型引射器空气引射试验台,对高工况下环型引射器启动特性进行了试验研究。试验结果表明,环型引射器启动压强明显高于运行压强;试验发现,引射马赫数越高,混合室收缩比越大,引射器启动压强越高。
The air-ejecting test facility is constructed for experimental investigation of the start performances of the supersonic annular ejector. The test results show that the ejector start pressure is remarkably higher than the operate pressure. It＇s observed that the ejector start pressure goes up with the increasing of the ejecting Mach number and the mixing-room contraction ratio.
