Based on the Reynolds-averaged Navier-Stokes(RANS) equations and structured grid technology, with second-order MUSCL scheme, combined with k-ω shear stress transport (SST) turbulence model and γ-Reθ transition model, the influence of the support brackets included in the wind tunnel model on the aerodynamic characteristics of the high lift trapezoidal wing (Trap wing) is studied. Firstly, the numerical methods are introduced briefly. Then, the wind tunnel models of the Trap wing configuration and the experimental activities are described. And then, on the basis of previous grid convergence study, the influences of the support brackets included in the wind tunnel model on the aerodynamic characteristics of the Trip wing configuration are studied with "fully turbulent" and transition modes. Finally, the conclusions are presented. Compared with the bracket-off numerical results, with "fully turbulent" mode, the support brackets decrease the lift coefficients, drag coefficients and nose-down momentum coefficient, resulting in the earlier stall angle. Compared with the experimental data, the bracket-on numerical results with the transition model are in very good agreement with test data and further study on the simulation technology of aerodynamic characteristics near the stall angle for Trap wing wind tunnel model is needed.
