FLUTTER OF CLAMPED SKEW PANELS WITH MID-PLANE FORCES IN SUPERSONIC FLOW

Abstract

The flutter problem of uniform, thin, flat, kotropic, skew panels clamped on all the edges und under the action of mid-plane forces is formulated on the basis of the classical small deflection thin plate theory. For the aerodynamics loading, the two-dimensional static approximation is used. Approximate buffer analysis is made by using the Galerkin method employing a double series of beam characteristic functions to represent the deflection surface. Results of numerical calculution for the critical dynamic pressure for a few configurations of rhombic panel under direct from in the stream-wise direction are presented.
