    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.
