摘　　要：风洞自由飞实验是一项特殊的地面风洞实验,用风洞自由飞实验研究了飞行马赫数M0.6~6.0飞行海拔高度最高达45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 aemerafts at 0.6 - 6.0 maeh 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 eriterion of assessing accuracy and reliability of experimentresult.
