PROPULSION DEVICE USING FLUID FLOW

Title:

PROPULSION DEVICE USING FLUID FLOW

Document Type and Number:

WIPO Patent Application WO/2011/031051

Kind Code:

A3

Abstract:

The present invention relates to a propulsion device using fluid flow, which quickly discharges the vortex flow generated on an upper surface of the propulsion device to the outside to improve the propulsion of the product provided with the propulsion device. For this purpose, the propulsion device of the present invention comprises: a fluid storage unit in which a downwardly curved fluid storage surface is formed between a first inlet line and a first outlet line such that a fluid storage space is formed on the fluid storage surface; and a fluid flow unit in which a downwardly curved fluid flow surface is formed between a second inlet line and a second outlet line which are outwardly and backwardly inclined such that a fluid flow space is formed on the fluid flow surface, wherein the fluid flow surface adjacent to the second outlet line becomes gradually flattened as it extends outwardly. The above-described configuration of the propulsion device of the present invention is advantageous in that the fluid introduced into the fluid storage space and the fluid flow space flows in a vortex to increase pressure, and the fluid flow space gradually narrows as it extends toward an end of the fluid flow surface so as to quickly discharge the fluid to the end of the fluid flow surface, thus increasing fluid flow velocity and improving the propulsion and thrust of transportation means provided with the propulsion device.
