The influence of afterburning chamber length on secondary combustion efficiency and flow field were analyzed based on direct-connected ground simulation test.

结合直连式地面模拟试验,分析了补度对掺混流场二次烧效率。

Dispersity of gas flow can be enhanced and afterburning efficiency can be improved by increasing primary nozzle numbers and nozzle expansion ratio.

增加一次喷嘴数目加大喷嘴扩张比增加了气分散性,提高了补效率。
