对波瓣喷管和圆喷管与弯曲混合管匹配的引射系统内流气动特性进行了实验研究，结果表明：（１）与圆喷管相比，波瓣喷管可以将系统的引射能力提高约１００％，混合管出口的峰值温度降低近１０％，而两者的总压损失几乎是一致的；（２）因弯曲引起的二次流及主流冲击弯曲壁面的扩散影响，混合管椭圆形排气口的长轴方向，尾缘温度明显地高于前缘温度；而在短轴方向，温度分布呈马鞍形状。 Experimental results show that: (1) Compared with the circular nozzle, the lobed nozzle can eject the system The capacity increase is about 100%, and the peak temperature at the outlet of the mixing tube is reduced by nearly 10%, while the total pressure loss is almost the same. (2) Due to the diffusion of the secondary flow and the mainstream impact bending wall caused by the bending, Oval exhaust port long axis direction, the tail edge temperature was significantly higher than the leading edge temperature; in the short axis direction, the temperature distribution saddle shape.
