Abstract
In the article the most useful propulsion complexes are described. General equation for transverse force on propulsion complex is shown. Authors discussed values of flow transformation coefficients discovered by A. Gofman. Disadvantages of general method for estimation of transvers propulsive forces are described. In the article the method for numerical evaluation of transverse propulsion complex forces is presented. This method is based on calculation of total force acting on hull-screw-rudder complex using full scale trials data. Values of coefficients which describe total force acting on propulsion complex are calculated using mean least squares method. Values were calculated for two types of cargo vessels. Verification of calculation was done.
