摘要：
Support interferences always affect the accuracy of the wind tunnel experimental data. Therefore studying support interference is of significant value in practice. The double rotating shaft support is a novel way of support. In this paper, numerical simulation has been taken to investigate the effect of the double rotating shaft support system on aerodynamic forces and moments of DBM model. It is found that the support system induces the lift coefficient and the drag coefficient to decrease and the pitching moment coefficient to increase. For the parts of the model which are above the wing plane, the lift coefficient and the drag coefficient decrease. And for the parts of the model which are below the wing plane, the lift coefficient and the drag coefficient increase. For the pitching moment coefficient, the influnence is opposite to that of force.
