Investigations on aerodynamic characteristics of S-Shaped Aerofoils with different locations of maximum camber

摘要

S- Shaped Aerofoils have been used as rotor blade section for design of reversible fans, reversible pumps in industries and most widely in tidal power platn for two way pumping and turbining operations (Kovalev 1961). It was also used as reflexed aerofoils for some early designs of low speed aircraft's (Durand 1963). This paper presents the wind-tunnel study results for S- Profiles namely S3525, S3515 & S3535 having their maximum cambers locate dat distances of 15
