Wind tunnel tests were performed using the same HOPE 2.5 percent scale model using the same balance and sting as the first step in developing wind tunnel uncertainties for HOPE. NAL 2 m x 2 m transonic wind tunnel and KHI 1 m x 1 m transonic wind tunnel which belongs to Kawasaki Heavy Industries Ltd., were used in the transonic speed range. Wind tunnel uncertainties which are estimated as root mean square values calculated from differences between two wind tunnel test results, are called tolerances in this report. Tolerances are compared with force measurement accuracy of the sting type balance and turn out to be almost the same order of balance error except in the about Mach number one speed range. Finally it is shown that wind tunnel test data with a model, the configuration of which is similar to HOPE, can be available in developing tolerances for HOPE, from comparison of tolerances between present wind tunnel test data and the past HOPE series wind tunnel test data., 資料番号: AA0000679000, レポート番号: NAL TM-704}, title = {HOPE風試誤差の初期評価}, year = {1996} }
