The invention discloses an adaptive continuously-adjustable
cavitation device structure. The adaptive continuously-adjustable
cavitation device structure comprises a benchmark
chassis, a rotatable telescopic
assembly and a drive mechanism
assembly which are connected with one another, wherein the benchmark
chassis and the rotatable telescopic
assembly rotate under the power drive action of a
servomotor, and the
diameter of an outer edge formed by multiple
layers of sector part groups in rotating is continuously adjustable along with rotation changes of the
servo motor. In the variable speed sailing process of an
underwater sailing body, the adaptive continuously-adjustable
cavitation device structure provides power through the drive mechanism assembly to drive the multiple
layers of sector part groups of the rotatable telescopic assembly to synchronously expand outward or contract inward, and adjusts the drive mechanism assembly according to change situation feedback of hydrokinetic parameters of an external flow field of the sailing body so as to realize
adaptive change of the
diameter of a cavitation device, thereby completing control for the size and the form of vacuoles, decreasing the
wetting area of the
underwater sailing body and reducing
pressure difference resistance additionally caused to the utmost, greatly reducing
frictional resistance and
total resistance, and greatly improving the maximum speed and sailing distance of the sailing body.
