A note on a solution of Possio’s integral equation for an oscillating airfoil in subsonic flow
Following a procedure analogous to that used by Schwarz for solving the integral equation for an oscillating airfoil in incompressible flow, a method of attack on the same problem for subsonic, compressible flow is outlined. The circulation and kernel to the circulation integral equations are expanded in series with the coefficients M'n and M2n In M, and a corresponding expansion for the Green's function is thereby implicitly determined. The solution up to (but not including) terms of 0(Mi, M* In M) is stated. A method of iteration for improving a given solution is also indicated.
