| Abstract: | 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. |
