Dynamic Response Analsysis of Flexible Wings

A methodology of dynamic response analysis for flexible wings by time-domain tool which is constituted by geometrically-exact nonlinear mixed-formulation couple with dynamic stall model ONERA, and unsteady vortex-lattice method. The Goland wing is included here to find the flutter velocity. It can be found that the flutter speed is 143.1 m/s and 169.4 m/s separately, and the main reason of different flutter speed is the three-dimensional effect.
