Keywords: supersonic flow, boundary layer, transition, saddle point method, complex ray theory

Stability and transition analysis of NEXST-1 wing model at Mach 2 was carried out using the eN method with the C-S-C saddle-point method and a complex ray theory. It was shown that there is no discrepancy between two analyses with different description of disturbance wave, and NLF concept was validated.
