Two-dimensional tests were conducted on a NACA 66(MOD) hydrofoil in the the GALCIT Hydrolab High Speed Water Tunnel (HSWT) . These tests were conducted using the hydrofoil with a. a rough leading edge, and b. a smooth leading edge, covering the following range of conditions: 1. Speed range of 30 ft/s to 60 ft/s 2. Angles of attack of 0° to 6° and 3. static pressures of 3. 03 psiA to 33. 54 psiA, corresponding to cavitating, incipient cavitation thru fully wetted flow conditions. These tests were performed in the two-dimensional test section of the HSWT and included measurements of: --Tunnel velocity. --Tunnel static pressure. --Lift, Drag and Pitching Moment forces (with tare forces removed). --Pressure coefficients on 13 taps, 12 at selected locations on the lifting surface, plus 1 location on the bottom surface. --High speed (strobe) flow visualization photography under flow cavitation conditions. --Airfoil gap dependence on static pressure.
