STUDIES OF A VENTILATED SUPERCAVITATING PROPELLER ON A TORPEDO TEST VEHICLE. PART 3. WATER-TUNNEL AND FINAL CABLEWAY TESTS, AND OVER-ALL SUMMARY OF THE PROJECT
NAVAL ORDNANCE TEST STATION CHINA LAKE CA
A full-scale torpedo test vehicle equipped with a ventilated supercavitating propeller was studied in the Garfield Thomas Water Tunnel at the Pennsylvania State University to obtain performance information and observe details of ven tilation flow. A peak efficiency of 70 was obtained near the operating advance ratio. Visual observations indicated improper ventilation of the propeller cavity. However, subsequent runs on the underwater cableway with the modified propeller gave improved acoustic results.
