摘要: 建立了高空浮空器蒙皮材料特性分析与组合优化方法,重点研究了蒙皮材料功能涂层热学特性与承力层力学特性之间的耦合作用关系,基于特定工况进行蒙皮材料分析优化,获得了基于Vectran平编承力层和镀铝PET薄膜功能涂层的高空浮空器蒙皮材料优化方案,并通过高空飞行试验验证蒙皮材料优化方案的可行性.结果表明,采用该方法获得的蒙皮材料优选方案合理,为浮空器耐压和高空长时间驻留设计提供了技术支持.

Abstract: The envelope material of high-altitude airship was analyzed and optimized. Coupling relationship between the thermal properties of the functional coating layer and mechanical properties of the load-carrying layer was researched. Analysis and optimization of the envelope material based on a special condition were carried out. An optimization scheme based on the Vectran flat knitting load-carrying layer made of flat knitting Vectran and functional coating layer made of aluminized-PET was obtained. High altitude flight test was used to validate the feasible of the optimization scheme. Results show that the optimization method is applicable to get feasible optimization schemes, which will provide technical support to the super-pressure long endurance of high-altitude airship.
