Abstract
Guide vane for a guide wheel of a pump or turbine having a guide vane body with two end faces, a guide vane leading edge, a guide vane trailing edge, and first and second flow-guiding side faces connecting the vane leading and trailing edges and forming different flow profiles along an axial extension. Each flow profile has a chord, a mean camber line, and a mean camber curve end angle between the mean camber line and the chord at the vane trailing edge. The guide vane is mounted to rotate about an axis of rotation defined by two pivot pins. Along the axial extension, the guide vane has at least one flow profile with a positive mean camber curve end angle and at least one flow profile with a negative mean camber curve end angle. The guide vane leading edge is tilted relative to the axis of rotation.
