THE PROBLEM OF WING FLUTTER NEAR A DEFLECTOR,

Abstract

An approach to the problem of wing flutter near a deflector is presented. The analysis assumes the flow of an incompressible nonviscous fluid flow, and the method presented may be used if an inverse operator can be found for the equations of elastic equilibrium of the wing. The nonsteady motion of a thin wing of infinite span upon a solid surface is depicted. This given expression is the basic system that is solved, and it can be regarded as the flutter equations for a wing with two degrees of freedom. The flutter is studied as a class of harmonic vibrations, and the solution, which contains transcendental functions, can be worked out by successive approximations or by another suitable numerical method. The proposed solution is applied, in an example, to the planar problem of flutter in a nonsteady flow of an ideal fluid. (Author)
