Aerodynamic force/heating measurement on hypersonic vehicle across different flow regions

The flow characteristics across different flow regions,engineering requires for aer-odynamic force/heating predicting technique,and the research status in China and foreign coun-tries are summarized.To solve the main problems of aerodynamic force/heating predicting tech-niques across different flow regions,some recent developments,such as the similarity criterion for experimental simulation based on viscous interaction and Knudsen number,framework opti-mization of microbalance as well as aerodynamic force measurement technique,the measurement of the middle and low heat transfer using infrared mapping,flow visualization and measurement, together with N-S/DSMC hybrid numerical method,have been presented,and further investiga-tion is suggested.
