摘要
Abstract
The double-faced deflector is designed for vertical launch system with which the jet flow can be drained to the both sides and the rear region. However, there is still a small part of high temperature flow seriously inpacting on the bottom of the vehi-cle where the communication cable and the rubber tire are mounted. In order to achieve the purpose of thermal protection, a new water-cooling system is designed, which is fixed on the chassis with water-injection pipe. This design is based on the endothermic gasification principle to reduce the energy of jet flow;besides, the impulse of water flow can also be used to cut off the gas flow to reduce the high temperature region. The result shows the thermal protection is effective. What's more, the corresponding relation ship between water velocity and the cooling effect is studied through the numerical calculation in which the coupling of mixture mul-tiphase model and species transport model are used. The optimized design can also be regarded as a theoretical reference for engi-neering application.关键词
