The ability to accurately predict the magnitude and phase of the time-pendent forces and moments generated by the blades of a propulsor is important due to the possible resulting vibrations and/or radiated sound. The present thesis considers the time-dependent thrust response of an open propeller due to operating in both spatially and temporally varying flows. The experimental investigation consisted of measuring, in a water tunnel, the time-dependent thrust generated by a series of propellers operating first in various spatially nonuniform inflows and then in various turbulent inflows. The spatial variations were generated by an up-stream strut, and the turbulence was generated by square mesh grids placed upstream of the propeller. Three propellers were considered. Measurement were made with each propeller operating over a range of advance ratios for each nonuniform inflow condition considered.
