Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
The influence of wing taper ratio on aeroelastic flutter is considered here. By applying assumed mode shape functions and Theodorsen´s unsteady aerodynamic theory to Lagrange´s equations, the equations of motion ready for flutter analysis is developed. A Matlab implementation of previously developed flutter analysis method is validated using Goland´s wing taken from open literature. It is observed that current results coincide well with the analytical solutions. The validated flutter analysis procedure is then used to calculate the flutter of straight planform tapered Goland´s wing with various of taper ratios. In this case, the results show that a wing with smaller taper ratio has higher flutter speed.
