摘要：This paper discussed the influence of the rhomboid zone of a wind tunnel on aerodynamic experiment for supersonic aircraft. A classical missile was chosen to be put in different positions to find the influence. Aerodynamic force and Flow distributions around the model were predicted with CFD method. Reynolds-Averaged Navier-Stokes Model, which can obtain a good balance between calculated expense and accuracy, was adopted for supersonic turbulence computation. It was found from the compared results that when the model size exceededthe range obviously, flow distribution can provide a significant influence on the aerodynamic results for a wind tunnel model of supersonic aircraft. Inversely, the influence can be neglected if the exceed range do not cause serious changes of flow distribution around the model. The present work can provide a significant reference for the design of the wind tunnel experimental models.
