Freestream (Open Water) propeller tests were carried out in the University of Southampton's 11' x 8' low speed wind tunnel. The four-bladed ship propeller tested had an overall diameter of 800mm and maximum hub diameter of 200mm and profile and sections based on the Wageningen B4.40 series. The ability to vary pitch setting was incorporated in the design. The performance tests were conducted at a range of windspeeds between 5m/s and 20m/s and propeller revolutions between 600 and 3,000rpm. Results are presented in terms of Thrust coefficient(K subscript T), Torque coefficient (K subscript Q) and Efficiency (?) against advance ratio J. A good comparison was found with published data for the four propeller pitch ratio settings tested. Leading edge roughness was applied at a pitch ratio of 0.95 and this was found not to affect significantly the thrust characteristics of the propeller.
