Abstract

Aeroelastic phenomena can occur to many engineering structures. Current design trends are aimed to engineering solutions to aeroelastic phenomena. Reliable aeroelastic analysis tools are needed to reduce expensive and time consuming experimental tests. The doublet lattice method (DLM) is one of the most powerful tools for linear flutter analyses in subsonic regime. The doublet-lattice method is still used almost exclusively for subsonic flutter clearance of flight vehicle being designed today since the high cost and technical complications with non�linear Computational Fluid Dynamics (CFD). This work are aimed to develop a computational program for calculation of steady aerodynamics force on general finite wing in incompressible regime. The present method shows good results for the steady and incompressible flow. It has been found that the results of the generalized aerodynamic forces slightly depend on the number and position composition of boxes.
