Title:
PROPULSION DEVICE USING FLUID FLOW
Document Type and Number:
WIPO Patent Application WO/2014/021653
Kind Code:
A1
Abstract:
The present invention relates to a propulsion device using fluid flow, and more particularly, to a propulsion device using fluid flow, in which the vortex flow generated on the upper surface of the propulsion device is discharged to the outside and the amount of fluid flowing through an added fluid supply unit is increased to further improve the speed of vortex generation and discharge, thus improving the drag and thrust of the product equipped with the propulsion device. The propulsion device of the present invention comprises: a fluid storage unit (10) having a downwardly curved fluid storage surface (13) formed between a front first inlet line (11) for the inflow of fluid and a rear first outlet line (12) for the outflow of fluid, a fluid storage space (14) formed on the top of the fluid storage surface (13), and a partition (15) formed at one side of the fluid storage surface (13); a fluid flow unit (20) having a second inlet line (21) that is formed at an end of the first inlet line (11) and is inclined in the outward and backward direction, a second outlet line (22) that contacts an end of the first outlet line (12) and is inclined in the outward and backward direction, a downwardly curved fluid flow surface (23) formed between the second inlet line (21) and the second outlet line (22), and a fluid flow space (24) formed on the top of the fluid flow surface (23), the length between the second inlet line (21) and the second outlet line (22) gradually decreasing as it proceeds outward, the fluid flow surface (23) contacting the second outlet line (22) gradually flattening as it proceeds outward; and a fluid supply unit (30) having a third inlet line (31) formed by cutting the front portion of intersection between the first inlet line (11) and the second inlet line (21) so as to further add, through the third inlet line (31), fluid to the flow of the fluid introduced from the fluid storage unit (10) to the fluid flow unit (20).
