Reduced order modeling of loads and deformation of a flexible flapping wing

This paper describes a methodology to predict the loads and deformation of a flexible flapping wing. An experimental setup capable of imparting a single degree of freedom flapping motion while measuring loads and deformation of a flapping wing was developed. Experimental results were obtained for a simple rectangular plate flapping in air at hover conditions. The deformation results show agreement with previously published data. The experimental setup is developed in conjunction with a reduced-order model for loads and deformation. A POD-Galerkin projection method is used to develop the model. The analytical results show a good correlation between direct numerical simulation and projection. The focus of the present work is hovering flight with simple kinematics and wing properties.
