Aerodynamic Coefficients for a Staggered Cascade of Oscillating Airfoils in Subsonic Flow,

Abstract

A method developed and described in an earlier paper is used to determine the aerodynamic coefficients for a cascade of staggered airfoils in compressible subsonic flow. In that report, the case of the unstaggered cascade was considered and in the present report the authors extend their earlier work to include a study of the effects of stagger angle on the aerodynamic coefficients. Particular attention is devoted to changes in the direct aerodynamic damping coefficients for plunging and pitching oscillations in high Mach number flow for particular values of the phase difference between the motions of adjacent staggered airfoils.
