The turbulent wakes behind a streamlined drag body, a jet-propelled body, and a propeller-driven body are studied experimentally in a subsonic wind tunnel at a principal nominal free-stream velocity of 206 ft/sec. Mean flow data taken downstream of the sterns of these bodies include velocity and static pressure distributions. The stream-wise variation of the maximum values of axial turbulence intensity and radial shear stress are also presented. The mean flow data for the wake behind the drag body compare favorably with previous experiments and establish a rigid reference for the wakes behind slender, self-propelled configurations. The downstream rate of decay is essentially the same for the drag and propeller-driven bodies, whereas the decay for the jet-propelled body is substantially faster.
