Benefits of technology

The present invention provides a method for improving the propelling force of a hydraulic propeller. This is achieved by using a gas guide device and a negative pressure suction force to guide in air bubbles and enhance the propelling force of the hydraulic propeller. The method involves enabling the intake flow of air to be guided into the gas release outlet, mixing with water to produce air bubbles, and then compressing the air bubbles to reduce their size. When the compressed air bubbles expand, they enhance the propelling force of the hydraulic propeller by utilizing the Bernoulli principle, gas compressible characteristic, Boyle's law, and the arrangement of the contracted end piece of the nozzle as an air compressor. The invention saves power consumption and cost.

Problems solved by technology

However, it costs a lot to improve the performance of the hydraulic propeller in this manner.

Embodiment Construction

[0028]Further features and benefits of the present invention will be apparent from the following detailed description of the preferred embodiment taken in conjunction with the annexed drawings. However, it is to be understood that the invention is applicable to any of a variety of boats. The present preferred embodiment is simply an example but not a limitation.

[0029]Referring to FIGS. 3˜5, when compared to the prior art design shown in FIG. 2 in which only a flow of pure water is driven out of the nozzle, multiple air bubbles 60 are generated in the flow of water 141 that is driven out of the nozzle of the hydraulic propeller.

[0030]Referring to FIGS. 4 and 5, a hydraulic propeller enhancement method in accordance with the present invention comprises the steps of:

[0031]a) providing a boat 20 in any type or shape, and then installing a hydraulic propeller 30 in the boat 20, wherein the hydraulic propeller 30 comprises a power engine 31, a water passage 33, a propeller 32 rotatably ac...

Abstract

The present invention relates to a hydraulic propeller enhancement method for enhancing the propelling force of a hydraulic propeller. The present invention uses a gas release outlet in the propeller at the area where the high-speed axial flow of water passes for guiding in a gas by means of a negative pressure subject to Bernoulli's principle. Thus, subject to Bernoulli's principle, gas compressible characteristic and Boyle's law and the arrangement of the contracted end piece of the nozzle to work as an air compressor for compressing air bubbles, the invention uses one single gas guide device and a negative pressure suction force to guide in air bubbles to enhance the propelling force of the hydraulic propeller.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to hydraulic propeller technology and more particularly, to a hydraulic propeller enhancement method for enhancing the propelling force of a hydraulic propeller by means of the application of a gas.[0003]2. Description of the Related Art[0004]A conventional for enhancing the propelling force of a hydraulic propeller is known by: increasing the horsepower of the propeller, using a different design of propeller or transmission system, or changing the angle of attach of the propeller.[0005]FIG. 1 illustrates a conventional hydraulic propeller 10, which comprises a power engine 11, a water passage 12, a propeller 13, a nozzle 14 and a directional nozzle 15. FIG. 2 illustrates a flow of water passing through the nozzle 14 of the hydraulic propeller 10. Because only a flow of pure water 141 is driven out of the nozzle 14, the reactive force thus produced is less strong, there is room for improvem...
