Research on vertical launching missile jet flow with jet vane

In order to research the impact on the surrounding environment of the high temperature and high pressure jet flow produced in the process of missile vertical launching with jet vane, the structured grids was built, and the computational fluid dynamic model was used to simulate the launching vehicle jet flow. The temperature and pressure contour of the deflector and baffle was obtained. The results shows that the ablation on the deflector was obvious, and the high temperature area was distributed by X shape. By comparing the actual experiment, we found the calculation of the simulation was reasonable, and it provided a reference for the follow study.
