Nonlinear Stochastic Flutter of a Cantilever Wing with Joint Relaxation and Random Loading

Abstract

The research project has generated a number of problems addressing the uncertainties and relaxation problems in aeroelastic structures. Specifically, three main problems that are of important concern to the aerospace industry and the Air Force technology have been addressed. These are: (1) The influence of structure uncertainties of the flutter of an aircraft wing. (2) Stabilization of wing flutter via parametric excitation. (3) Influence ofjoint relaxation on the flutter of aeroelastic structures. These problems are addressed in the next three chapters.
