摘要

可控扩散叶型(CDA)的优化设计是目前国外对亚音、跨音速压气机叶型研究的主要内容之一。本文对CDA研究的必要性、CDA产生的背景、第一代CDA和考虑端部流动的第二代CDA的特点及设计方法进行了综述。CDA起源于超临界机翼翼型

通过控制吸力面的扩压过程

消除或减弱激波、降低损失、增加可用冲角范围。围绕这一设计准则和目标

提出了很多设计方法

归纳起来主要有反问题设计方法和正问题设计方法。国内对CDA的研究起步较晚

且大都集中在理论和设计方法的研究上。

Abstract

The optimum design of Controlled Diffusion Airfoils (CDA) is one of the main research fields in subsonic and transonic profile design for multistage compressor.This paper reviews the necessity of CDA research

the background of CDA development

the features and design methods of first generation CDA and the second generation CDA with consideration of cascade endwall flow.The CDA is originated from the supercritical airfoil.Controlling the diffusion on the suction surface of an airfoil

can eliminate or decrease the shock wave

reduce the loss and enlarge the range of incidence.Around this criterion of airfoil design

many design methods have been proposed

which can be classified into inverse method and direct method.The CDA research in China started later than many other countries

and concentrated mainly on its principles and design methods.
