The purpose of the present study is to investigate submarine rudder stern-plane configuration to obtain optimum manoeuvring characteristics. Three configurations are investigated: +. x and y configuration. The equations of motions were derived with the external forces and moments consist of contributions due to the hydrostatics. https://www.markbroyard.com/super-save-whole-wheat-phyllo-pastry-sheets-jufka-sa-integralnim-brasnom-12pcs-x-450g-jami-supply-great-choice/
