Aeroelastic Analysis of a Flexible Membrane Wing

<p>The focus of this research proposal is the investigation of the aeroelastic effects of a flexible lift augmentation system (LAS) wing. This research involves characterization of the forced vibration response of a wing appendage used to augment short field take off and landing (STOL) operations.</p> <p>Although flutter theory is now well understood, the LAS presents the complications of a highly deformable airfoil shape as well as larger structural damping values compared to metal wings.</p> <p>The proposed research will involve derivation of the equations of motion aided by experimental data from nodal excitation of the wing; stiffness and rigidity modeling from static wing loading and collection of flight test data to characterize the potential flow around the membrane wing.</p> <p>The knowledge gained from this research will be of critical importance in assuring the safety of flight by identifying the critical flutter speeds, as well as establishing a good basis for the structural design of future lift augmentation structures.</p>
