An Approximate Method for the Calculation of Nonstationary Air Forces at Subsonic Speeds
Abstract
The present report explains and illustrates a method of computing the non-stationary forces and moments on an oscillating airfoil at subsonic speeds. The process is based on the well known Possio integral equation relating the pressure on the airfoil to the normal velocity. Part I of the report contains the theoretical development which leads to the required equations for determining the lift and moment. In Part II the method of Part I is applied to the computation of the aerodynamic lift and moment coefficients for four principal degrees of freedom of the airfoil.
