以多孔喷管代替普通收缩喷管或收-扩喷管作为引射喷管系统的主喷管,进行模型实验,结果表明,这种构型引射喷管不仅能显著降低噪声,而且具有良好的气动性能。
The multi-hole nozzle is used to replace the normal shrink nozzle or the convergent-divergent nozzle as the main nozzle of the ejector nozzle system, and the model experiment is carried out. The results show that the ejector nozzle of this configuration can not only reduce the noise remarkably but also have good The aerodynamic performance.
