Abstract
A cavitator system for suppressing a cavity buoyancy effect and a control method thereof are provided. The cavitator system for suppressing a cavity buoyancy effect includes a cavity generating unit disposed at a front portion of an underwater vehicle and generating super-cavity, a pneumatic hose transferring compressed air stored in a compressed air tank to the underwater vehicle, a ventilation module positioned at a tail portion of the underwater vehicle and including at least one hole ventilating compressed air transferred through the pneumatic hose vertically downwards, and a controller sensing rise of a cavity tail portion and a change in posture of the underwater vehicle when a super-cavity is generated and ventilating compressed air through the ventilation module such that a vertically downward lift is generated at the cavity tail portion.
