Vertical Launching System(VLS) is an equipment that carries a large number of guided missiles and launches missiles vertically from a warship in case of emergency. Korean Vertical Launching System(KVLS) adopts Hot launching method that rocket motor ignites inside the launcher, causing flames to gather within structures such as canister, plenum, uptake, and etc. In this launching method, the high-temperature and high-pressure flames from missiles affect the launching system and the adjacent hull structures, so a lot of research on its structure and heat resistance is required. To do that, it is important to understand the flow characteristics of the flame in the launcher system. In this study, a CFD analysis is performed in two cases where the missile is fired normally and restrained due to abnormal behavior. For the numerical simulation, a two-dimensional Reynolds-averaged Navier-Stokes(RANS) solver is adopted. An overset grid method is applied to simulate the dynamic behavior of a missile for normal launch case. A transient pressure response on the wall inside and outside of KVLS is suggested to understand the flow-field inside the launching system. KCI Citation Count: 0
