3) compound-lean stator
弯曲静叶
1.
The experimental investigation into the effects of stator clocking on the performance in a low-speed repeating stage axial compressor with compound-lean stators show that stator clocking has a significant effect on the compressor efficiency, and the effect becomes pronounced as the mass flow rates increase.

2.
This paper is focused on the experimental study of the effects of stator clocking on the performance of a low-speed repeating stage axial compressor with compound-lean stators as well as the one with conven- tional stators (the baseline) for comparison.
结果表明,随 Clocking 位置不同,上游静叶尾迹被输运到下游叶列流道中不同周向位置并与该列叶栅不同区域流体掺混是导致压气机性能变化的主要原因,且采用弯曲静叶的压气机性能随Clocking 位置不同而变化的幅度要小一些。

1.
The flow fields were measured in the blade tip clearances of the cascade with the conventional straight and positive curved blade.
详细测量了常规直叶片与正弯叶片栅间隙内与上、下游流场,比较两套叶栅的实验结果发现:叶片正弯减小了叶顶后3/5轴向弦长范围内的横向压力梯度,并消除了上通道涡,因而大大削弱了泄漏流与瑞壁横流之间的相互干扰,相对漏气量与叶栅流动损失都显著降低。
6) curved stator blade

补充资料:弯曲工艺的概念及弯曲件
1.弯曲工艺:是根据零件形状的需要,通过模具和压力机把毛坯弯成一定角度,一定形状工件的冲压工艺方法。
2.弯曲成形工艺在工业生产中的应用:应用相当广泛,如汽车上很多履盖件,小汽车的柜架构件,摩托车上把柄,脚支架,单车上的支架构件,把柄,小的如门扣,夹子(铁夹)等。
弯曲的基本原理:以V形板料弯曲件的弯曲变形为例进行说明。其过程为:
1. 凸模运动接触板料(毛坯)由于凸,凹模不同的接触点力作用而产生弯矩, 在弯矩作用下发生弹性变形,产生弯曲。
2. 随着凸模继续下行,毛坯与凹模表面逐渐靠近接触,使弯曲半径及弯曲力臂均随之减少,毛坯与凹模接触点由凹模两肩移到凹模两斜面上。(塑变开始阶段)。
3.随着凸模的继续下行,毛坯两端接触凸模斜面开始弯曲。(回弯曲阶段)。
4.压平阶段,随着凸凹模间的间隙不断变小,板料在凸凹模间被压平。
5. 校正阶段,当行程终了,对板料进行校正,使其圆角直边与凸模全部贴合而成所需的形状。
弯曲变形的特点: 弯曲变形的特点是:板料在弯曲变形区内的曲率发生变化,即
弯 曲半径发生变化。从弯曲断面可划分为三个区:拉伸区、压缩区和中性层。
