The experiment is performed for a disk cavitator at different cavitation numbers and ventilation conditions. From the experiment, a stable and transparent supercavitation between submerged body and water can be observed when ventilated. The drag of the submerged body is decreased to 28% of its original value, when ventilated supercavitation appears and the quantity of the ventilated air is over a certain limit, the drag of the body keeps constant.
