Abstract

The problem of an elastic lifting body in a randomly perturbed flow is considered. It appears that the phenomenon of hydro-elastic induced vibrations is controlled by a stochastic differential operator. By using the theory of stochastic perturbation, a new technique of solution for this class of problems is proposed leading to a very effective numerical solution. 1 Introduction This paper is focused on flow-induced vibrations of an elastically suspended wing in a random flow. The pitch and plunge wing oscillations are excited by stochastic fluctuations of the inflow velocity that are superimposed to an average deterministic flow component. The problem, per se theoretically i
