An investigation has been conducted to determine whether three-dimensional flows may be efficiently utilized in axial-flow fan and compressor rotors so that the spanwise load distribution may he suitably varied to obtain high pressure rise. Two rotors, one with approximately uniform and one with solid-body downstream tangential-velocity distributions, were designed and tested at the design blade angle. Radial surveys of total pressure, static pressure, and flow angle were made upstream and downstream of the test rotors through a quantity-coefficient range. Tests of the solid-body rotor were also conducted at a large value of tip clearance.
