Studies of Blade Shank Form and Pitch Distribution for Constant-Speed Propellers

Abstract

Replacement of round blade shanks by faired ones produced improvement of efficiency which in turn increased with advance ratio. Objectionable discontinuities of performance occurred when pitch angles of exposed shank elements exceeded 90 degrees. Efficiency requirement is most nearly satisfied over wide range of operating conditions by blade twist curve which is the envelope of twist for all blades of uniform design pitch.
