摘要

针对典型布局条件下直升机/粒子分离器的一体化流动特性进行了仿真研究.利用相关试验数据对仿真方法的有效性进行了检验

将整体式粒子分离器安装至类“阿帕奇”直升机外型上

形成了一种典型直升机/粒子分离器布局方案

并分析了其在不同前进比下的一体化流场特性.结果表明:较高前进比下

在粒子分离器进口上游的齿轮箱外罩上出现了复杂的三维流动分离

使得粒子分离器在较不均匀的进口来流条件下工作.与独立粒子分离器状态相比

一体化条件下粒子分离器主流出口、扫气流出口的总压损失均有所加大

增幅分别为1%和8%.

Abstract

Integrated flow field characteristics of helicopter/particle separator of typical layout were studied by simulation method.Firstly

the validity of the numerical method used was verified by experimental data.Then

the integral particle separator was installed onto helicopter like “Apache”

then a typical layout scheme of helicopter/particle separator was formed

and the integrated flow field characteristics in different advance ratios were analyzed.The study results show that under the condition of higher advance ratio

a complex three-dimensional flow separation appears in the gear box upstream the entrance of the integral particle separator.That is to say

the particle separator operates under the condition of nonuniform freestream.Moreover

compared with the independent particle separator

the total pressure loss of the particle separator under integrated condition at the mainstream exit and the scavenge exit both increased by 1% and 8%

respectively.
