Abstract : A method, based on quasi-steady lifting-line theory, has been developed for calculating the sway force and rolling moment acting on a deeply submerged yawed or unyawed submarine due to actuation of sailplanes in the differentially deflected mode. Short digital-computer programs have been written to facilitate quick execution of the calculations. Comparison of calculated and measured sway force and rolling moment shows fairly good agreement.
