Throughout history, shipbuilders have sought to increase the speed of ships. The parameters of the propeller have a great influence on the efficiency of the use of the vessel and the marine engineer needs to know and understand the principles of interaction of the elements of the propulsive complex. The parameters that determine the effectiveness of the elements of the propulsive complex include : the speed of the vessel, the diameter and speed of the propellers, the effective power of the main engines, etc. These parameters have a great influence on the main indicators of commercial and technical operation of ships of the navy
Propulsive complex, screw, hull of a marine vessel, interaction efficiency, screw parameters, components of resistance to the vessel
