On the Theory of Oscillating Airfoils of Finite Span in Subsonic Compressible Flow

Abstract

The present report is concerned with the problem of the oscillating airfoil of finite span, within the frame of the linearized lifting surface theory. The aim of this study is the development of a theory which incorporates simultaneously the effects of three-dimensionality of the flow and of compressibility of the fluid. As an exact solution of this problem, even within the limitations of the linearized theory, presents very great difficulties, it is worth while to work toward an approximate theory which is valid provided the aspect ratio of the lifting surface is not too small.
