新型车载同心筒流场机理与热环境研究
Research on flow field mechanism and thermal environment of a new vehicle-carried concentric canister launcher
摘要
Abstract
Based on the RANS governing equations,2nd-order AUSM scheme and dynamic mesh technology with spring based smoothing method,and laying based zone moving method, the axisymmetric flow fields of different shapes of concentric canister launcher(CCL)were simulated numerically.Both the flow field mechanism and missile thermal environment characteristics of differ-ent structure form were obtained to deal with the thermal environment evaluating and improving problem of vehicle-carried concentric canister launcher.The traditional optimization CCL schemes were enumerated,moreover,a new concept CCL which is suitable for ve-hicle-carried environment was proposed.The comparison of the numerical results show that compared to the traditional optimization CCL,the new concept CCL may lower the temperature of the gas around the missile significantly the“reverse absorption effect”of high temperature jet can be well inhibited;the inverted absorption cold gas into the internal canister plays a very good role in cooling down the missile and launch system;the thermal environment of external cylinder is also improved by the mixed gas of the jet and cryogenic gas.关键词
