Abstract

Abstract: X-37B is the most successful trans-atmospheric orbital vehicle in the US after the space shuttle. Analyzing the aerodynamic characteristics in its flight corridor can provide significant reference for the development of similar spacecraft in China. With the progress of HPC, CFD has become an important method in aircraft design and flow field analysis, in which the correlation between the flight and ground data is part of the validation function. The grid independence and correction of an X-37B-like aircraft have been studied, followed by the research on the Reynolds number effect and support interference effect. The difference between the high-altitude aerodynamic data and wind-tunnel results are computed and studied. The grid scale has a significant effect on the axial drag in the subsonic flow, and a minor effect on the normal force and pitching moment. The Reynolds number has a significant effect on the axial force, drag force and lift-drag ratio, while the effect becomes complex as the Mach number increases. The presence of the support sting in the wind tunnel has a remarkable effect on the aircraft base drag under subsonic and transonic inflow conditions, and correction of the support effect should be modified in a certain way.

Key words: X-37B aircraft, flight corridor, correlation between flight and ground data, grid convergence, Reynolds number, support sting
