Propeller-Disk Wake Survey Data for Model 4989 Representing the FF 1052 Class Ship in a Turn and With a Bass Dynamometer Boat,

Abstract

Experiments are described in which the wake in way of the propeller disk was determined for several conditions on a model of the FF 1052 Class ship in connection with an investigation to determine blade loadings on a controllable pitch propeller. The wake surveys were conducted with and without a dynamometer boat behind the hull model to determine the effects of the presence of the dynamometer boat on the flow through the propeller disk of the model. Next, wake data were obtained for the model in several conditions while turning in the Rotating Army Facility. Finally, the model was towed in a straight line with a yaw angle corresponding to that used in the turning experiments to assess the differences in results for these two techniques.
