In this paper,unstructured grids and standard k-epsilon(2eqn) model,to establish the appropriate equations to solve for NACA0012 wing, got the lift coefficient of the wing,the lift-drag ratio with(sea) from the curve of the near-Earth and the fitting function.Unstructured grids and standard k-epsilon(2eqn) model and the sliding mesh,dynamic simulation of near-Earth boundary blast pressure effects on near-Earth spacecraft,has been in force under the test conditions change with time trend curves.Our results may be flying under the aerodynamic performance analysis and experiencing explosions near the unstable ground(sea) condition of the aircraft stability,security,designed to provide some theoretical support for the study of near-Earth ground effect vehicles.
