ABSTRACT:
In a gas turbine power plant including a separate power turbine, a guide apparatus located downstream of the power turbine rotor will have to cope with gas flows varying considerably with respect to velocity and inlet direction. To provide improved flow handling properties the individual vanes of the guide apparatus are divided, and comprise a stationary portion extending over the full axial depth of the vane, and a smaller portion, including part of the thicker nose of the vane only. This smaller portion is displaceable in relation to the stationary portion, so the vane, when its portions are brought together, presents a rounded front edge, and, in the displaced position of the portions, presents a sharp front edge.
