The property analysis and combination optimization method of high altitude aerostat skin material are established. The coupling relationship between the thermal properties of the functional coating and the mechanical properties of the bearing layer is studied emphatically. The skin material analysis and optimization , The optimization scheme of the high altitude aerostat skin material based on the Vectran flatbed bearing layer and the functional coating of the aluminized PET film was obtained and the feasibility of the optimization scheme of the skin material was verified by the high altitude flight test.The results show that this method The obtained skin material has a reasonable scheme and provides technical support for the design of the aerostat in terms of pressure resistance and long-term residence at high altitude.
