CFD (Computational Fluid Dynamics) analyses of a flow field around supersonic transport, NEXST-1 (National EXperimental Supersonic Transport-1) are conducted. The CFD results are compared with flight test data. In this paper, C(sub D) and C(sub p) discrepancies between them are mainly discussed with consideration of the effects of transition and local geometry change by protuberances of measuring instruments. As for the C(sub D) discrepancies, CFD results have more (4-9 cts) profile drag, which could be the sum of spurious numerical error and turbulence model mismatch. As for the C(sub p) discrepancies, C(sub p) values at local points are definitely influenced by protuberances. Through the discussion, we also demonstrate how the CFD simulation can augment the validity of the flight test data.
