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 my be 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.
