摘　　要：简述西北工业大学自适应壁风洞研究课题组在“八五”期间开展跨声速柔壁自适应壁风洞试验技术研究的主要研究工作成果。简介该校的高速柔壁自适应壁风洞的设计及主要参数，以及在该风洞中开展的低超声速消除波反射的研究、近声速的自适应壁风洞试验技术研究和跨声速自适应壁试验段优化设计的研究。This report describes the main progress on the testing technique research for testing 3-D models in 2-D transonic flexible adaptive wall wind tunnel at Northwestern Polytechnical University(NPU). It includes the parameters of transonic flexible wall adaptive wind tunnel of NPU,the research of reducing shock wave reflection at low supersonic speed,the research of optimizing the design of transonic adaptive wall test section for extending the wall interference free region, the testing technique of flexible adaptive wall wind tunnel at near sonic speed. The results show that in 2-D flexible adaptive wall test section,the shock wave reflection can be reduced effectively at low supersonic speed,at near sonic 3-D models also can be conducted,and for testing aircraft models the width to height ratio of test section B/H=1. 4 is suitable.
