Title:
HYBRID SHIP PROPELLER
Document Type and Number:
Japanese Patent JP2023044488
Kind Code:
A
Abstract:
To prevent complication of an internal structure of a hybrid ship propeller and inhibit deterioration of cruising performance of a ship during planing.SOLUTION: A hybrid outboard engine 1 includes: an internal combustion drive propulsion unit 11 which generates propulsion power of a ship by an internal combustion engine; and an electric propulsion unit 30 which generates propulsion power of the ship by an electric motor. The electric propulsion unit 30 is detachably attached to a portion, ranging from a rear part of a middle case 21 to an upper rear part of a gear case 22 in the internal combustion drive propulsion unit 11, and arranged at a position higher than an anti-cavitation plate 23 so that propellers 34, 54 of the electric propulsion unit 30 sink below a surface of water during low speed traveling, which is not in a planing state of the ship and the propellers 34, 54 of the electric propulsion unit 30 get out from under the surface of the water during planing of the ship.SELECTED DRAWING: Figure 2
