Abstract

A novel propeller is composed of an axle and multiple blades, and features that the axial length of blade tail is elongated by 2-4 times and the edge of blade consists of anti-resistance curve, external edge curve which is an arc line, a transition curve and a water curve which is an arc line, a transition curve and a water yielding curve. The partial blade between said external edge curve and a particular arc has a concave surface. Its advantages are high shap speed increased by 30%, low vibration, and simple structure.

Description

technical field

[0001] The invention relates to a propeller, in particular to a novel propeller. Background technique

[0002] Shipping is one of the country's major transportation industries, ocean transportation, inland waterway transportation and various industrial ships. It is one of the industries for the country's economic development, and the propeller is the main part of the ship. The tail of the traditional propeller blade is short. The oblique precession method causes power loss, is laborious, increases energy consumption, and is not economical. see figure 1 , the propeller in traditional technology is composed of four curves connected in turn, the anti-resistance line k, the connecting line m, and the waterline n, forming a side oblique precession mode. Contents of the invention

[0003] The object of the present invention is to provide a novel propeller with simple structure, little effort and low energy consumption.

[0004] The present invention is realize...
