    Nonlinear Galerkin analysis of flutter of curved plates is made using shallow shell (von Karman) equations and quasi-steady aerodynamic theory; for two-dimensional curved plate, it is shown that flutter amplitude is of order of rise height of streamwise curved plate, aerodynamic loading caused by inherent streamwise curvature of plate significantly effects flutter boundary, and comparison with experiment gives good qualitative agreement; modal equations of motion of three-dimensional plate with double curvature are also derived, but not studied numerically.
