The range of +/- 14 cm in the left and right directions and the range of +/- 30 cm in the up and down directions from the center of the Schlieren window of the measurement section of the wind tunnel were divided into 2 cm intervals, 15 intervals horizontally and 31 intervals vertically. At these meshed areas, pressure data were measured and then the Mach number distribution was obtained. As a result, it was shown that the uniformity of the Mach number was better than one percent in the lower Mach number range but increasingly poorer for the higher Mach number. In addition, the Mach number distributions were measured at the cross sections, 15 cm upstream and 12 cm downstream from the center of the Schlieren observation window, and the inclination of the air flow was inferred., 資料番号: AA0028634003, レポート番号: NAL SP-45},
