The activity described in this technical report is part of contract 07CT17 - FLUID TECHNO. The activity regards propeller's testing in a cavitation tunnel with measurement of the advance coefficient J, the thrust coefficient Kt and the torque coefficient Kq. These measurements are done for values of the advance coefficient J comprised between 0.2 and 1.5. For each condition high speed video recordings of the cavitation pattern have been acquired. Performance curves are reported, obtained at constant flow velocity and by varying the advance coefficient through the rotation speed of the propeller. The performance curves are reproduced at different levels of the facility static pressure in the test section (from 1.7 atm to 0.2 atm), i.e. at constant tunnel pressure.
