ABSTRACT:
In an automotive power plant, where the power turbine will repeatedly be stalled while different amounts of gas pass its stationary rotor, detrimental conditions at the outlet stator are avoided by designing the individual guide vanes so the leading edges are inclined in the direction of flow by an amount of 20.degree.-60.degree. with respect to a radial plane normal to the power turbine rotor axis.
The inclination may be selected so it runs substantially straight from the radially inward end of the vane to its tip, or from the radially inward end as well as from the top to provide a notched, or U-shaped profile.
