Becker duct stabilises water flow

摘要

Wake fields of full form ships often mean that the propulsion efficiency of propellers is less than optimum because the inflow of the water to the propeller is insufficient. The newly available Mewis Duct from Becker Marine Systems has been designed to stabilise the flow of water to the propeller and create an even load on each blade. The asymmetrical and individually placed profiled fins of the Mewis Duct will have a stator effect and generate a pre-swirl in the opposite direction of the spin of the blades, therefore creating a higher load on the propellers and creating more thrust. Becker believes that using the Mewis Duct along with a Becker rudder will improve wake field optimisation and provide greater manoeuvrability.
