The equations of the motion of an elastic wing are derived from Lagrange’s equations in time - domain. The wing is modeled as a cantilever beam rigidly connected to the root. Considering assumed modes of cantilever beam, aerodynamic forces and moments acting on the wing are derived using strip - theory in an unsteady incompressible potential fluid flow. The governing aeroelastic equations of the system have been introduced in dimensionless form. These equations are solved via a numerical method. Comparisons between obtained results and both available experimental data and the results of some cited references indicate a close agreement. %> http://mme.modares.ac.ir/article-15-227-en.pdf %P 93-106 %& 93 %! %9 %L A-10-12415-1 %+ Tarbiat Modares University %G eng %@ 1027-5940 %[ 2009
