PERFORMANCE OF SUPERCAVITATING PROPELLER ON ONR HYDROFOIL BOAT XCH-6 (DTMB PROPELLER 3785)

Abstract

The open-water performance of the 10-inch supercavitating propeller installed on the Office of Naval Research Hydrofoil Craft XCH-6 is described. Within the limits of accuracy obtainable on an open-water test vehicle, performance of the installed propeller compares favorably with model test data. Torque and thrust coefficients of the installed propeller were slightly lower than anticipated from the model tests, while propeller efficiencies for foilborne speeds to 43.5 knots (50 mph) were approxiately 7 to 8 units higher than anticipated. Trends of these data with respect to speed (from 30.4 knots to 43.5 knots 35 to 50 mph) agree closely with the model tests. (Author)
