The Form of the Solutions of the Linear Integro-Differential Equations of Subsonic Aeroelasticity.

Abstract

The solution of the subsonic flutter problem, when the commonly used linear differential equation model is replaced by the more correct linear integrodifferential equation model, is studied and the nature of the system's free motion established. The different forms appropriate to two-dimensional and three-dimensional flow, and to the cases when the system has a zero characteristic value, are developed in detail. It is shown that, for large time t , the behaviour can variously be like 1,1/LOG T, 1/t sq. or 1/t cubed. (Author)
