| Abstract: | The numerical model of gas flow spread on launcher box was built by using CFD methods and the flow pressures at pre-cover and post-cover of launcher were obtained. Through rational designs pre-cover and post-cover opening pressure, pressure wave is big enough to automatically open launcher cover. By flight experimental verification, numerical analysis and experiments are in good agreement, indicates the gas flow model on launcher is correct and reasonable. |
