A torpedo test vehicle utilizing a ventilated supercavitating propeller was the subject of an experimental program carried out on the underwater cableway facility at Morris Dam. Vehicle runs, incorporating an 11-in.-diam ventilated supercavitating propeller DTMB 3819, showed the propulsive efficiency to average 79. As gas was passed through the blade-ventilation holes in increasing amounts, the advance ratio progressively decreased by 10 but it could not be concluded that the efficiency was directly affected. Propeller performance data obtained with the actual test torpedo agreed with water tunnel results reported by other laboratories.
