A wake survey was conducted to aid in the design of a kort nozzle propeller for a salvage ship ARS-50 represented by DTNSRDC Model 5391-1 Hydronautics Model 7925-4. Pressure measurements were made with a rake of five-hole pitot tubes in order to obtain the flow velocity in the plane of the propeller. Several model configurations were tested in order to identify the effect of the nozzle on the flow and also the effect of a propeller installed just aft of the rake for the purpose of simulating a realistic flow through the nozzle. Harmonic analyses of the circumferential distribution of the velocity component ratios were performed on the model experimental data and the results are reported herein. Author
