摘要： 为了研究部分喷嘴流路关闭对预旋供气系统供气流量和供气温度等特性参数的影响，在部分喷嘴流路打开和关闭工况下进行了实验研究。研究结果表明：随着喷嘴压比增大，以几何流通面积定义的喷嘴流量系数先增大后基本保持不变，转动对喷嘴流量系数的影响在1.6%以内，可以忽略；在系统压比为1.30时，由于阀门关闭不严和关闭后预旋腔腔压的变化，供气流量降幅是喷嘴几何流通面积降幅的67.8%~81.8%，实验状态下阀门关闭会导致供气温度降低约1.2~2.4K。

Abstract: In order to study the effects of partial nozzle flow path closure on the characteristic parameters such as air supply mass flow rate and temperature of the pre-swirl air supply system， experiments were carried out under conditions that partial nozzle flow path was open and closed. The results show that as the nozzle pressure ratio increases， the nozzle discharge coefficient defined by the geometric flow area increases first and then remains basically unchanged. The influence of rotation on the discharge coefficient of the pre-swirl nozzle is within 1.6%， which can be ignored. When the system pressure ratio is 1.30， due to the valve is not closed tightly and the variation of pressure in the pre-swirl cavity after closing the valve， the amplitude reduction of air supply mass flow rate is 67.8% ~ 81.8% of that of nozzle geometric flow area， which is less than that of nozzle geometrical flow area. Closing the valve causes the air supply temperature to decrease about 1.2~2.4K in the experimental state.
