Abstract
A combined disc-type cavitation structure for underwater navigation of an underwater vehicle has an underwater vehicle and a fairing. A plurality of cavitators having sequentially increased outer diameters are sequentially arranged in the fairing. A cavitator receiving 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 a whole by means of the cavitator receiving groove. The cavitator located at the front-most end is a first cavitator, and the remaining cavitators are second cavitators. The first cavitator is connected to the underwater vehicle by means of a buffer. Each second cavitator is respectively connected to the underwater vehicle by means of a driving device configured to axially move the corresponding second cavitator.
