摘要
本文对五种弯曲角度和四种截面比的弯曲混合管与十二波瓣喷管匹配,进行了试验研究,获得了弯曲角度,截面比与引射能力和掺混效果之间的关系,本文的研究结果对直升机发动机红外抑制器设计和参数优化,具有指导性意义。
An experimental study on pumping and mixing eflect in ejector composed of curved mixing duct and lobed nozzle has been carried out Five kinds of bended angle and four kinds of area-ratio of curved mixing ducts and a twelve-lobe mozzle are used. The interrelations between bendeded angle, area-ratio and pumping, mixing effect have been obtained. It is great significance for guiding helicopter engine infrared suppressor design and parameter optimization.
