航空发动机术语简介

编号

术语

解释

备注

1

喘振

压气机的一类气动失稳现 象，由于气流分离导致的增

压能力的丧失，产生周期性的倒流、解除分离、正常流动、分 离、再

倒流的循环过程。

可通过中间级放气、

< br>双转子自动防喘、

可调静子叶

片和导向叶片、采用处理机 匣等方法来防喘。

2

痒振

进气道处于深度超临界状 态下，通道中的附面层与正

激波相互作用形成的分离区具有强烈的脉动性质，

周期性变化，

从而引起管道中激 波的高频振荡，

这种不稳定流动现象

称为痒振。

4

质量附加

涡扇发动机将从热机 中获取的有效能分配给了更

多的工作介质，参与产生推力工质增多，因此推力增大；

“同参数”

使涡扇发动机在相同热效率条件下降低了排气速度，减小 了余速损

失，具有更高的推进效率，因此提高了总效率，降低了耗油率；

B

越

大，速度越低、推力越大。

5

余速损失

绝对坐标系中气流以绝对速度

(C9

﹣

C0)

排出发动

机所带走的能量称为“ 余速损失”

。

yusun

6

能量分配原则

为减少气流掺混 引起的损失，在混合室进口

两股气流总压应大致相等，即

Pt5 II=Pt5

，风扇压比的选择要遵循能

量最佳分配原则。
