An experimental investigation of the blade loading and spanwise effects on the rotor wake is presented. The investigation was limited to a study of a low subsonic and incompressible wake flow found downstream of a lightly loaded rotor. Measurements were made with a triaxial hot wire probe mounted in the stationary frame of reference at six radial and nine axial positions. At each measurement location, the rotor was run at different operating conditions to discern the effects of blade loading on the wake. Nearand far-wake measurements are given, including mean velocity and turbulence intensity characteristics. The loading and spanwise effects on rotor-wake characteristics were found to be substantial.
