Using the prediction system of boundary-layer transition, the spatial growth of traveling waves is examined in the boundary layer over the outer wing of the NEXST-1 semispan model. It is found from the computational results that TS waves are dominant to transition on the wing. Moreover, it is noted that TS waves directed to the leading edge are amplified even in the accelerated boundary-layer flow near the leading edge. However, the growth of TS waves is suppressed around the designed angle of attack., 資料番号: AA0045948035, レポート番号: NAL SP-57
