Ship propeller design
WebSince in general a propeller can only be designed to satisfy a single design point, this involves a unique specification of the power absorbed, shaft rotational speed, ship speed and a mean radial wake field: the controllable pitch propeller being the partial exception to this rule when it would be normal to consider two or more design points. WebBy dividing the world’s leading propeller and shaftline systems into three different offerings, C-Line, P-Line, and X-Line, Kongsberg Maritime can provide high quality propeller solutions fully adapted to the Customer’s needs and requirements.

Ship propeller design
Did you know?
A propeller imparts momentum to a fluid which causes a force to act on the ship. The ideal efficiency of any propulsor is that of an actuator disc in an ideal fluid. This is called the Froude efficiency and is a natural limit which cannot be exceeded by any device, no matter how good it is. Any propulsor which has virtually zero slip in the water, whether this is a very large propeller or a huge drag device, approaches 100% Froude efficiency.
