Transition location of an unmanned and scaled supersonic experimental airplane (NEXST-1) is measured by the flight test. The wing of NEXST-1 is designed with our original CFD-based inverse design method to apply the natural laminar flow concept. It is the first challenge to apply the natural laminar flow wing concept to a supersonic vehicle. The concept is tried to validate by measuring the surface pressure and the transition location. In this paper, the flight data analysis to detect transition location by four kinds of sensors and the results are summarized. Also the development of numerical transition prediction and its results are summarized. The transition location at the design condition, which is detected experimentally, delays in contrast with that at the off-design point. Therefore the natural laminar flow effect is confirmed.
