| 摘 要： | 在基线发动机性能计算的基础上,利用引射喷管抽吸特性和二次流进气系统的流量平衡技术,研究并提出了一种多缝引射喷管方案,用于降低喷管超音段壁面的温度,并开发出多缝引射喷管尺寸与分析程序ENSAAP。利用该计算程序,可分别计算设计条件下和非设计条件下的冷却空气流量和安装多缝引射喷管后所造成的安装推力损失,以及安装多缝引射喷管对发动机重量和飞机航程的影响。本项研究为发展具有低可探测性的先进发动机排气系统提供了可行的冷却方案和设计基础。

| Abstract: | A computer program,so-called the Ejector Nozzle Sizing and Analysis Program (ENSAAP),has been developed for ejector nozzle sizing and analysis.It was applied to the required ejector slot heights by using models of the slot pumping,secondary air induction system,engine cycle and slot cooling effectiveness.For an example,an engine cycle and aircraft mission has been used to demonstrate the inlet/ejector sizing process,as well as the performance sensitivities to an ejector installation.This program provides an approach to the optimization of advanced aircraft performance with reduced IR signature. |
