| 摘 要： | 为新研制的单级跨声速风扇设计了３种不同形式的处理机匣，圆弧斜槽处理机匣、轴向斜槽处理机匣和反旋涡式处理机匣，并在该单级跨声风扇上进行了实验研究。采用新建立的试车台数据实时采集与监控系统，测量了该单级跨声速风扇的总性能和采用处理机匣后风扇的总性能、基元级性能。通过分析表明圆弧斜槽处理机匣使负扇的稳定工作裕度获得较大的改善，并且与实壁参考机匣相比，提高了峰值效率，其作用效果明显地优于其他形式的处理机匣

| Abstract: | Three types of different casing treatment were designed for new developed single stage transonic fan. They are arc curved skewed slot casing treatment, axial skewed slot casing treatment and counter vortex slot casing treatment. By using real time data gathering and test system of the aero engine test bed, the detail measurement of single stage transonic fan performance with and without different casing treatments were made. Research results show that a further improvement is obtained with arc skewed slot than other casing treatments in stall margin and peak efficiency. |
