一种先进的固体火箭冲压发动机堵盖设计

Design of an Advanced Port Cover for Solid Rocket-Ramjet Engine

简要对比了固体火箭冲压发动机不同形式进气道出口堵盖设计方案,指出可烧蚀堵盖是今后技术发展的方向。在此基础上详细设计了一种该类型堵盖,它是由钯和铝组成的层压板结构。同时,还对其进行了应力分析,结果表明该设计方案可以满足固冲发动机对进气道出口堵盖的强度和密封要求,可为可烧蚀堵盖在未来先进空空导弹上的应用提供参考。

In this paper the different types of port cover on the air intake ports in solid rocket-ramjet engine are compared in brief,and the results indicate that the consumable port cover is the direction of development in future.On the basis of above discussion a port cover made of a laminate of Pd and Al is designed in detail.At the same time the stress analysis is described,and the results show that this design is according with strength and seal of port cover on the air intake ports in solid rocket-ramjet engin...
