Numerical Calculation and Simulation of Missile Jet-Airplane Interaction
We describe the flow of missile jet by use of Euler equation series and construct total variation diminishing (TVD) scheme of finite volume with four ranks Runge-Kutta method of multi-steps of time increase. When we numerically calculate and simulate Euler problem, the results accord with actual physical phenomenon and indicate that it remains high precision and resolving power to shock wave. In relevant conditions, by use of the method mentioned above, we numerically calculate and simulate the process of missile jet-airplane interaction; obtain the fluid fields isograms of pressure, density and temperature at different moment after the missile on airplane have been launched; reveal their interaction mechanism each other. We draw a conclusion: when the shock wave caused by missiles jet acts on the surface of airplanes body, it will produce the shock wave reflection and the pressure on the surface of airplanes body reaches maximum.
