For flows of free-stream Mach numbers below the drag-divergence Mach number, the spanwise uniformity of the section drag coefficient is good in the region around the center section. Although the spanwise uniformity is bad for flows of freestream Mach numbers above that, the drag-divergence Mach number can be obtained accurately. In order to improve the spanwise uniformity of the section drag coefficient, it would be necessary to survey the wake at a station close to the trailing edge rather than at a station 1-3 chords downstream of the trailing edge, as was done in this experiment. The spanwise uniformity of pressure distribution and of section lift coefficient is fairly good in the region around the center section. The spanwise uniformity is better at Mach numbers below MLD than at Mach numbers above MLD., 資料番号: NALTR0665000, レポート番号: NAL TR-665}, title = {On the Spanwise Uniformity of Wind Tunnel Test Data of Transonic Airfoils}, year = {1981} }
