Abstract
Wind tunnel model free-flight test is a special wind tunnel test technique between ordinary wind tunnel test and flight test.In this paper,the development of high-speed wind tunnel model free-flight test technology is introduced.Firstly,the development of high-speed wind tunnel model free flight test technology is introduced.Secondly,the common characteristics of wind tunnel model free flight test technology and its three sub-technology —— general model free-flight test,multi-bodies separation wind tunnel free-flight test and high speed wind tunnel drop-model test —— the difference between the three sub-technologies and their respective application fields are summarized. The common characteristics are support interference-free aerodynamic data and the model free flighting,so that the transient aerodynamic force can be measured at the moment of separation.The repeatability of the test is a common disadvantage compared with the general wind tunnel test.For the three sub-techniques,each has its own characterisitc,and has specific technology and application field from others.The research fields of the three sub-techniques cover the dynamic stability and all kinds of multi-bodies separation of aircrafts.The general wind tunnel free-flight test is applied for the research of aircraft dynamic stability,and the other two sub-techniques are applied in the research of all kinds of multi-bodies separation.While the different multi-bodies separation problems are covered,by the multi-bodies separation wind tunnel free-flight test and high speed wind tunnel drop-model test technique, because of the difference between the specific technology of the two sub-techniques.关键词
