In this report, based on the results of flight tests carried out in Australia 1996, aerodynamic characteristics including both dynamic and ground effects were estimated and compared with the previous results of wind tunnel tests. As a result, the differences were found among different kinds of wind tunnel test, in spite of having found a small difference, almost considered within the extent of variation, between the estimated characteristics from flight tests and the obtained results from tests of standard wind tunnel applied to the design of control system of experimental vehicle. The reason for these differences can be attributed to the difference of supporting method, rigidity, and shape of the model., 資料番号: AA0001434010, レポート番号: NAL SP-38}, pages = {95--109}, publisher = {航空宇宙技術研究所, National Aerospace Laboratory (NAL)}, title = {ALFLEX実験機空力データベースの比較評価}, volume = {38}, year = {1998} }
