Title:
SUPPORT STRUCTURE OF SHIP TAIL SHAFT AND SHIP
Document Type and Number:
WIPO Patent Application WO/2018/171125
Kind Code:
A1
Abstract:
Disclosed is a support structure of a ship tail shaft, the support structure comprising a supporting ring (100) selectively sheathed on the tail shaft and a support body connecting the supporting ring (100) with a ship body. The support body comprises a contact edge in an upstream direction of water flow and a separation edge in a downstream direction of water flow, with the separation edge being twisted relative to the contact edge. In the support structure, the support body twists correspondingly in a water flow direction, so that the support body is fitted to a flow field direction. With the twisting form of the support body, the additional pressure difference resistance generated by the support body is reduced, thereby improving the hydrodynamic performance of the ship and achieving the purposes of energy conservation and emission reduction.
