抄録

We applied a method based on Complex-ray theory (CRT) to the stability analysis of three-dimensional boundary layers at supersonic flight test conditions of the JAXA's experimental airplane called, NEXST-1, and investigated its capability. The dispersion relation was numerically obtained by the eigenvalue equations and linear parabolized stability equations (PSE). By adapting two kinematic wave theoretical models, we found out which wave type was dominant at measured transition locations of the flight test in 2005. As a result, it has been found that the dominant wave type on the outer wing section of the NEXST-1 was wedge-shaped disturbance, on the other hand, it was two dimensional wave-packets on the inner wing section. From the view point of transition prediction using an e_N method, there was no difference of transition N factors (N_tr.) between the results by the eigenvalue solutions with and without CRT method. Only a use of PSE with CRT, however, was able to reduce the discrepancy of N_tr. among cross sections, owing to the nonparallel effect of flows.
