Title:
COMBINED DISC-TYPE CAVITATION STRUCTURE FOR UNDERWATER NAVIGATION OF NAVIGATION BODY
Document Type and Number:
WIPO Patent Application WO/2023/072200
Kind Code:
A1
Abstract:
The present invention provides a combined disc-type cavitation structure for underwater navigation of a navigation body, comprising the navigation body and a fairing. A plurality of cavitators of which the outer diameters are sequentially increased are sequentially arranged in the fairing; a cavitator accommodating groove matched with the cavitator located on the front side is arranged in the center of the front surface of the cavitator located on the rear side in every two adjacent cavitators; the plurality of cavitators can be integrated into one piece by means of the cavitator accommodating groove; the cavitator located at the foremost end is a first cavitator, and the remaining cavitators are second cavitators; the first cavitator is connected to the navigation body by means of a cushioning device, and the cushioning device is configured to cushion the acting force between the navigation body and water when the navigation body enters the water; each second cavitator is respectively connected to the navigation body by means of a driving device, and the driving device is configured to axially move the corresponding second cavitator. In the present invention, the positions of the cavitators can be adjusted according to navigation requirements, and two or more cavitators can be integrated into one piece to form a larger supercavitation bubble.
