Abstract (en)
[origin: EP0798447A2] The turbine blades (6-13) in the ring duct between the outside of the turbine and the inner drive unit have improved profiles to reduce turbulence and hence reduce drag. The blade profile is thicker near to one wall of the duct and extends into the duct with reducing profile. The blade contouring is applied to both the movable blades and the fixed blades. The thickening is more pronounced at the rear of the blade and the blade is curved more at the thicker profile.
