摘要： A propeller (10) setting a small duct (20) of the present invention includes a propeller (10) and a duct (20). A diameter Ddin of the duct is set to 20% or more and 50% or less of a diameter Dp of the propeller (10), and a pitch H of the propeller (10) is a decreasing pitch which reduces in a radial direction of the propeller (10), and which becomes a maximum value at a blade root of the propeller (10) and becomes a minimum value at a blade tip of the propeller (10). The small duct (20) is placed in front of and close to the propeller (10). According to this, in an actual sea, cavitation is suppressed, and a load distribution of the propeller (10) in its radial direction which governs efficiency is optimized by utilizing interference with respect to the small duct (20).

摘要： The present invention relates to a vortex generator that generates an asymmetric wake for reducing propeller noise and vibration, the vortex generator being capable of reducing propeller noise and vibration by reducing cavitation on blade surfaces of the propeller in a vessel by controlling a flow moving to the propeller in the vessel. The present invention provides a vortex generator that generates asymmetric wakes for reducing propeller noise and vibration, the vortex generator being cable of minimizing cavitation noise by generating asymmetric wake distribution for increasing the speed of a flow in the first quadrant of a propeller where cavitation is generated most by reducing an angle of attack of a blade by changing an axial speed using asymmetric wakes.
