Embodiment Construction

[0062] Identical or similar components are provided with the same reference numerals in the different exemplary embodiments.

[0063] figure 1 A grid according to a first embodiment of the invention is shown. The grid 100 comprises first radially extending rods 101 arranged at an angle to each other and spaced apart. First ends of the first radially extending rods 101 are connected together at the center of the grid 100 . The second end of the first radially extending rod 101 may be connected to the tunnel section of the tunnel thruster ( figure 1 not shown). The first radially extending rods 101 are straight and of equal length.

[0064] The grid 100 also includes a first connecting rod 102 . Each first connecting rod 102 is connected between two adjacent first radially extending rods 101, so that one end of the first connecting rod 102 is connected to one first radially extending rod 101, and the first connecting rod 102 The other end is connected to another first radi...

Abstract

The present invention provides a grid (100) for a tunnel thruster (200). The grid (100) comprises a plurality of first radially extending bars (101) arranged at angular intervals from each other, and a plurality of first connecting bars (102), each of the first connecting bars (102) being connected between adjacent first radially extending bars (101).

Description

technical field [0001] The invention relates to a grid for a tunnel thruster according to the preambles of the appended independent claims. The invention also relates to tunnel thrusters and ships incorporating such grids. Background technique [0002] Tunnel thrusters, also known as transverse thrusters or steering thrusters, are widely used in ships, such as ships and boats. Tunnel thrusters are usually installed at the bow or stern of the ship, below the waterline, to provide lateral propulsion to support the ship's maneuvering, mooring, station keeping and dynamic positioning. [0003] An exemplary tunnel thruster includes a tunnel section that is open at both ends. A propeller is mounted within this tunnel section, which can be rotated by an electric motor to generate propulsion in either direction. [0004] A known problem associated with tunnel thrusters is the increased resistance to the movement of the vessel through the water. A known solution to this problem i...
