Abstract

The flexible inflatable wings has become a hotspot with its unique advantages such as the lightweight, portability, small folding volume, fast response, low cost and so on. But because the significant geometric deformation of the flexible film appears under the inflatable pressure, which seriously affects the wing load and deformation characteristics. In this paper, considering the obvious geometrical deformation compensation influence, the pressure load, the envelope stress-strain and deformation law are studied for the flexible inflatable wing. And with the example of element of flexible wing film, the characteristics of the initial shape design and film load analysis are researched and a analysis method of flexible deformation wing is introduced based on the deformation compensation. And the design of the flexible film load considering the deformation compensation could improve the precision of the flexible wing structure after inflating and the surface accuracy of the large deformation surface, meanwhile, the theoretical analysis method is provided for the initial design and processing of the flexible inflatable wing.
