大展弦比机翼低速静气动弹性模型的设计、制作和风洞试验
Design, manufacture and low speed wind tunnel test of a high aspect ratio wing static aeroelastic model
摘要
Abstract
For a high aspect ratio wing,it is important to investigate the characteristic of aerodynamics in large elastic deformation.A significant way is to execute the test in wind tunnel using scaled elastic structure similar model.In this paper,a kind of static aeroelastic model testing technique in low speed wind tunnel was developed.A scaled elastic structure similar model was designed and manufactured for a high aspect ratio wing,and the test was performed in NUAA(Nanjing University of Aeronautics and Astronautics) NH03 wind tunnel.The paper describes the details of the elastic model technology and gives the results of the wind tunnel test.It indicates that the elastic model technology is suitable for investigating static aeroelasticity characteristics of a high aspect ratio wing and the results of the wind tunnel test is significant for high aspect ratio wing.关键词
