摘要: In this study, Euler simulations of the X-31A experimental aircraft are performed in order to analyse flow characteristics configuration as well their influence on aerodynamic coefficients. The discretized geometry is based full with exception inlet, which has been faired for reasons grid generation simplicity, and assumption sharp leading edges numerical reasons. Solutions obtained DLR solver CEVCATS, a cell-vertex finite volume approach block structured grids. Comparison available wind tunnel data shows good agreement coefficients up maximum lift. vortex formation burst phenomena canard wing investigated pitching moment coefficient identified.
