Equations were solved using the cell-centered finite volume spatial discretization and four-stage Runge-kutta time-stepping scheme on unstructured mesh with standard convergence acceleration techniques such as local time stepping and implicit residual smoothing.The flow fields for the bomb carrier interior weapon cabin at different states(the open-up angles of interior weapon cabin′s doors are 8 degree and 45 degree separately) are simulated.The aerodynamic loads to act on interior weapon cabin′s doors can make them close-up.The aerodynamic loads are inequable at the different open-up angles of interior weapon cabin's doors.The results are logical and authentic.
