风洞自由飞实验足一项特殊的地而风洞实验,用风洞自由飞实验研究了飞行马赫数MO.6~6.0飞行海拔高度最高达4.5公里范围内多个飞行器的动态气动特性.因而首先需回答风洞自由飞实验结果的精确度、可靠性.坚持用天(飞行)--地(地面风洞自由飞实验)一致作为评定实验结果准度、可信度最重要最终的考核标准.

Wind tunnel free-flight experiment is especial wind tunnel experiment aground. We, the only one throughout the country, have conducted the research of unsteady aerodynamic characteristics of several aerocrafts at 0.6 ~ 6.0 mach and up to 45 kilometers of altitude by wind tunnel free-flight experiment. Thus the accuracy and reliability of wind tunnel free-flight experiment should be provided. The accord between flight and wind tunnel experiment is the most important criterion of assessing accuracy and reliability of experiment result.
