Water tunnel tests of NACA 66_(1-012) hydrofoil in noncavitating and cavitating flows

The results of force tests on the NACA 66_(1-012) hydrofoil in noncavitating and cavitating two-dimensional flow are presented. The results of wind tunnel tests on this profile are included for comparison with the results of the noncavitating water tunnel experiments. The noncavitating experiments were made at Reynolds numbers from 0.89 to 1.65 x 10^6 and the cavitation experiments at Reynolds numbers of 0.89 and 1.18 x 10^6
