超声速导弹多功能结构设计

Multi-Functional Structure Design in Supersonic Missile

针对超声速导弹,设计了一种集承载、热防护与热电转换等功能于一体的多功能结构,并建立了此结构的热-结构耦合仿真分析模型。研究表明,上述结构具有较好的热防护性能和承载能力。将热电转换技术应用于超声速导弹可解决防隔热/承载一体化结构的热短路效应,并利用此效应可实现热量的再利用;将导弹舱段设计为内壁、外壁与隔热层,并在内壁安装热电装置,使结构兼具承载、热防护与热电转换多种功能,对超声速导弹设计具有指导意义。

A kind of multi-functional structure combined with load bearing capacity, thermal protection and thermoelectric conversion was designed for supersonic missile, and the coupled thermo-mechanical numerical model was established for this structure. The research shows that, the multi-functional structure has a good thermal protection property and load bearing capacity. Thermal short-circuiting effects of thermal-structural integrated system can be eliminated by using thermoelectric conversion technology in supersonic missile, and the heat can be reused as well. The missile cabin is composed of inner wall, outer wall, structural thermal insulating layer, and the thermoelectric device is installed on the inner wall. Multifunction, such as load bearing capacity, thermal protection and thermoelectric conversion, is achieved by this structure, which is meaningful for guiding supersonic missile design.
