Document Type and Number:
WIPO Patent Application WO/2018/105451
Kind Code:
A1
Abstract:
The present invention comprises: a duct (22) which is located in front of a propeller of a ship, and is fixed to a bossing (11) side so as to surround the rotational axis (L1) of the propeller; inside fins (24) which have outer ends fixed to the inner peripheral side of the duct (22) and extend radially inward towards the rotational axis (L1); and outside fins (25) which are located in the extension direction of the inside fins (24), and which have inner ends fixed to the outer peripheral side of the duct (22) and extend radially outward. If the rotation of the propeller is clockwise as viewed from the rear of the ship, the attack angle with respect to influent water is formed on the port side, and θi > θo is set where θi is the installation angle of the inside fins (24) with respect to a reference plane including the rotational axis (L1) and θo is the installation angle of the outside fins (25) with respect to the reference plane.
