Static Force and Moment Coefficients of a Propeller Stabilized and a Finned Torpedo Shape

摘要

Static force and moment coefficients were measured in the High Speed Water Tunnel on nonpowered models of a propeller-stabilized and controlled torpedo. The tests were made on three propeller configurations and four body-fin combinations. Representative tests were conducted over a range of tunnel velocities. Data are presented asudfunctions of body angle of attack and propeller shaft deflection. A comparison is presented of the experimental data and the theoretical analysisudof T. Lang of the Naval Ordnance Test Station, Pasadena.
