A method for designing a ship propeller in an ice area

Abstract

The invention belongs to the field of ships. A method for designing a ship propeller in an ice area is disclosed. A lifting line method and a lifting surface method are combined in the design. The design results are taken as the initial input of the lifting surface method, and the special parameter limits of the ship propeller in the ice area are input in the design process. The strength is checked according to the classification society code, and then the hydrodynamic calculation is carried out. The invention realizes the propeller design of the ice area ship and provides a reference for thedesign and construction of the ice area ship. The method can be implemented easily by programming, is high in design efficiency, and can reduce wake shrinkage and aft-ship wake effects, and reduce cavitation and noise; the special parameter limits of ship propeller in ice area are inputted in the design process, which further improves the design efficiency and meets the needs of ship propeller operation in complex ice area environment.

Description

technical field [0001] The invention belongs to the field of ships, and in particular relates to a method for designing ship propellers in ice regions. Background technique [0002] The Arctic Passage is made up of two shipping lanes: the "Northwest Passage" along the coast of Canada and the "Northeast Passage" along the coast of Siberia. [0003] The Northeast Passage is also known as the "Northern Sea Route", and most of the voyage is located in the offshore waters of the Arctic Ocean off the northern coast of Russia. Starting from Northern Europe, it goes eastward through the five major waters of the Arctic Ocean, the Barents Sea, the Kara Sea, the Laptev Sea, the Novosibirsk Sea and the Chukchi Sea until the Bering Strait. On the Northeast Passage, there are as many as 58 straits connecting the five seas, of which 10 are the most important. [0004] Most of the Northwest Passage is located in the waters of the Canadian Arctic Archipelago, starting from the Bering Strai...

AI Technical Summary

Problems solved by technology

However, for the propellers of ships sailing in ice areas, the available atlases are very scarce, mainly because countries keep the technology of ships in ice areas secret, especially the propeller design of icebreakers, due to its high technical content and involves intricate political and military and economic interests, all countries strictly keep their information confidential, so there are very few design drawings that can be referred to

There are great deficiencies in the design of ship propellers in ice regions by using the map design method
