STUDIES OF A VENTILATED SUPERCAVITATING PROPELLER ON A TORPEDO TEST VEHICLE. PART 1. PERFORMANCE RESULTS

Abstract

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.
