Summarization of the Characteristics and Development of Hypersonic Quiet Wind Tunnel
高超声速静风洞特点和发展概述

Conventional hypersonic wind tunnel suffers from high noises and fluctuations of incoming flow,which are typically one to two orders of magnitude higher than the practical fight levels.Quiet-flow hypersonic wind tunnel is very essential to develop in order to seek phenomenon of hypersonic transition in tunnel.Thus,first of all,basic concept of quiet wind tunnel is recommended,several key points of technology and design method about laminar nozzle are discussed,noise characteristic and diagnosis way are anal...
