A complete theory is developed in Part I of these two papers for the analysis of oscillating airfoils in cascade in uniform incompressible flows. The theory fully accounts for the geometry of the airfoils and cascade parameters. It is shown that the strong mean velocity gradient near the leading edges of the airfoils significantly affects the unsteady pressure, forces and moments acting upon the airfoils. In Part II the aeroelastic characteristics of a loaded cascade are investigated for one and two degrees of freedom oscillations.
