高温火箭燃气的排导一直是研制新的箱式发射系统的关键问题.发射架和舰艇需要用特殊的材料来防护.“标准”导弹垂直发射系统(VLS)的设计要求特别苛刻,因为导弹产生大量燃气.对内部燃气流穿过新导弹发射系统的分析一直是一个难题.例如穿过发射系统的强压力波就决定了机械强度的设计值.从高温燃气流来的紊流对流热传递,提供了发射系统的最大热输入,因此,要求为装运箱和发射架内表面设计防护材料.燃气流穿过系统时会发生复杂的不明的化学反应,从而使燃气的化学成份以及它的物质性质在每点各不相同.
The guiding of high-temperature rocket gas has always been a key issue in the development of new box-type launching systems. Launchers and ships need to be protected with special materials. The design of the “standard” vertical launch system (VLS) is particularly harsh because the missile generates Large quantities of gas The analysis of the internal gas flow through the new missile launch system has been a challenge, for example the strong pressure waves passing through the launch system determine the design of the mechanical strength, the turbulent convection heat transfer from the hot gas stream, Provides the maximum heat input to the launch system and therefore calls for the design of protective materials for the shipping container and the inner surface of the launcher.A complex unknown chemical reaction takes place as the fuel gas stream passes through the system so that the chemical composition of the gas and its material properties Different at each point.
