See full text

A wicket gate for a hydraulic turbine or pump contains a blade being defined by a pressure surface, an oppositely facing suction surface, a leading edge and a spaced apart trailing edge, a first trunnion, a second trunnion, an air inlet aperture, an air passage and at least one air outlet aperture. The profile of the suctions side surface of the blade along a cross section through a point P1 and a point P2 is concave. Whereas point P1 is located on the suction side surface of the trailing edge where an air outlet aperture is located and point P2 is spaced apart from point P1 by less than 10% of the wicket gate length D and point P2 is located upstream of point P1 on a line perpendicular to the trailing edge starting at point P1.
