PANEL FLUTTER OF PLATE UNDER SUBSONIC FLOW IN TWO-DIMENSIONAL APPROACH
RESUMO
The method of calculating panel flutter of a flat plate is proposed in two-dimensional formulation. It is assumed that the upper surface of the plate is passed by a subsonic flow and the lower surface contacts with still air. Unsteady velocity potential is used to calculate aerodynamic pressure values. An integral-differential equation of plate oscillations in air flow is derived. Its discretization is fulfilled using finite element method. Several examples of numerical calculations of panel flutter are considered.
