Abstract
Disclosed are a cavitation device and an underwater moving body having the same. The underwater moving body includes a body; and a cavitation device for generating a cavity which encloses an outer circumferential surface of the body, wherein the cavitation device includes: a plurality of flap-up/down members rotatably connected to the body, disposed to cover the outer circumferential surface, and disposed in a circumferential direction and a lengthwise direction of the body in a matrix form; and a pressing module for flapping up the flap-up/down members such that the cavity is generated, as the flap-up/down members being rotated are inclined from the outer circumferential surface. Under this configuration, the cavitation device can freely generate a partial cavity or a super cavity on the surface of the underwater moving body. Furthermore, a ventilation module for forming a ventilated cavity may be coupled to the cavitation device.
