吸附式压气机叶型设计技术研究

以开发能提高叶片负载能力的吸附式压气机(The aspirated compressor)叶型设计技术为目标,以某发动机高压压气机的前三级为工程背景,研究了超高负荷的单级吸附式压气机气动方案,初步建立了从子午流道设计、S1流面基元叶型反问题设计到带附面层吸除S1流面计算分析的一套设计方法.以单级方案动叶叶尖截面作为设计实例,演示了开发的设计方法能够设计出基本达到设计要求的吸附式压气机叶型.

Investigation of the aspirated compressor design methodology

This paper described the efforts to develop the inverse airfoil design methodology of the aspirated compressor,showing the potential to greatly increase compressor blade loading.The study began with a single stage aspirated compressor aero design based on the performance requirement of the front three stage of an advanced test HP compressor,in order to determine the high loading for following development of the airfoil inverse design methodology.Based on the method developed,the successful design for the ro...
