Abstract
An outlet guide vane for an axial compressor extending along a rotor axis, includes an airfoil extending in a span direction from a radially inner end at 0% height to a radially outer end at 0% height. The airfoil has a suction side and an opposite pressure side, both sides extending in a chord direction from a leading edge to a trailing edge, wherein for each profile of the airfoil a stagger angle between the chord and the rotor axis is defined. A more favorable air flow profile behind the outlet guide vane is achieved by a new shape of the outlet guide vane, wherein a stagger angle distribution in the span direction has a curved course having a minimum located between 40% and 60% in the span direction, a first maximum at 0% and a second maximum at 100% in the span direction.
