Webvariables for designing the propeller such as pitch angle, flow angle, chord distribution at the blade span and twist distribution. Blade elements theory will be used for designing ... Since the propeller sharp edge will be set at a given geometric pitch point, nearby speed vector will make a stream approach on the segment. Lift and drag of the ... 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. The essence of the actuator-disc theor…
