This paper presents current research in the development of a validated finite element model of inflatable wings. The methodology used to develop such a model is described along with some of the challenges faced during this process. Experimental testing of the wing is presented, including measurement of response to static loadings as well as modal analyses over a range of internal pressures. A discussion of finite element modeling processes is given, including comparisons between different material models, both linear and nonlinear, as well as a discussion on mesh convergence studies. Finite element predictions are compared with results from experimental testing for static loading cases and for modal response. An effective nonlinear material model was found to approximate modal response more accurately, while static response is more accurately modeled by an effective linear orthotropic model.
