Note (General): In the development of a supersonic natural laminar flow wing in the NEXST-1 program, a transition analysis code (LSTAB code) based on a current e^N method was originally developed. Recently to improve the precision of the analysis method, a new analysis procedure was investigated. This procedure consists of estimating laminar boundary layer based on CFD analysis and computing stability characteristics by LSTAB code. To verify the procedure, two simple configurations of a sharp cone and the nose cone of the NEXST-1 airplane were analyzed. Although they are axisymmetric bodies, they have very complex flowfield at nonzero angle of attack (AOA). Therefore, it is supposed that present analysis procedure is effective to analyze their transition characteristics. In this article, it is numerically shown that the cross flow instability on the side surface is dominant on transition phenomenon at nonzero AOA.
