A new method is proposed for calculating values of the influence function in the MULTHOPPtype method of solution of subsonic oscillatory lifting-surface theory. This method partially applies ALWAY's iteration method for the steady lifting-surface theory in order to be effective when integration points lie very near to a collocation section. Numerical calculations prove that converged values are obtained in reasonable computer time.
