Abstract:

Results of wat r-tunnel tests on the base-vented hydrofoil model show that the lift and moment coefficients and the lift coefficient derivative are all esse ti lly independent of ventilation number and are approximately equal to coefficient of uncamb red airfoils having th sam aspect ratio. HE DR G COEFFICIENT AGREED ONLY PARTIALLY WIT TWO-DIMENSIONAL CAVITY DRAG THEORY. The aximum lift-to-drag ratio w s 6.5 when fully vented and 2.4 wh n fully wetted. Due to the reduced blockage of the Free S URFACE Water Tu nel at the C ALIFORNIA Institute of Technology, t e minimum ventilation number K was 0.02 and the minimum air-flow rate coefficient Qcr provi i g full ventilatio was 0.026 RATE INCR ASING AND . RAT CR ASING. Author
