Abstract

This paper presents development of a structural model of warping inflatable wings. In order to quickly and effectively analyze the effects of aerodynamic loading and to consider design options for warping actuation, a detailed finite element model is required. The methodology used to develop and initially validate a finite element model of an inflatable wing is described in this paper. The wing is a complex structural system including intricate geometry, internal pressurization and a woven fabric shell structure. This effort includes determination of material properties via laboratory tests. These are verified with finite element simulations of simple inflatable cylinders constructed of similar material. The process used to create a finite element simulation of the wing is presented, including modeling assumptions and nonlinear analysis stages. Results for various loadings of interest are included. Finally, the paper presents initial validation of the finite element model using results of static cantilever wing bending and twisting loads applied at the inflatable wing tip. Although the model represents important deformation characteristics of the inflatable wing, it is generally too stiff compared to experimental results. Future modifications to the model and further validation are also discussed.
