abstract: The interaction of the Elastic, Inertia and Aerodynamic forces is a dynamic phenomena resulting in flutter. Dynamic Aero elasticity is critical for a high-speed subsonic class of AerialVehicles. In the presentwork, dynamic Aero-elastic analysis of the Unmanned Aerial Vehicles (UAVs) has been studied for a stiffened composite structure. The flutter speed and the corresponding flutter frequencies are computed using the Velocity-Damping (V -g) method. The V -g method is employed to estimate the flutter speed and flutter frequencies, for a high-speed subsonic composite wing structure, designed and developed at ADE. Also the improvement of the flutter frequencies over the existing metallic wing structure is discussed. The work can be further extended to develop an optimized composite structure with higher margins in flutter speeds.
