Limited amplitude panel flutter with a temperature differential


Journal Article

Panel flutter is a self-excited aeroelastic phenomenon in which a panel's oscillations are derived from energy absorbed from the flow over the panel. This paper addresses the nonlinear response of a square, cantilevered isotropic panel subject to quasi-steady supersonic aerodynamics over the upper surface and a time invariant temperature differential between the panel and its surroundings. Rayleigh-Ritz assumed modes are used to describe the in-plane and transverse displacements. In-plane and transverse modal convergence analyses are conducted. It is found that the steady state response depends on the initial conditions, the panel and flow parameters, and the temperature differential.
