Abstract
Experimental investigations directed towards improving the range of operation of the Wells self-rectifying air turbine are reported. Several rotor configurations were tested. These include (1) rotor blades with their center line offset from a radial line, (2) rotor blades with leading edge slats, (3) rotor blades with trailing edge devices, (4) rotor blades with blunt trailing edges, (5) biplane rotors, (6) large thickness-to-chord ratio blades and (7) a turbine with a high level of inlet turbulence. Most of the configurations tested showed improvements in the operation range primarily by postponement of stall.
