Abstract: Exhaust diffuser and method for manufacturing an exhaust diffuser It is described an exhaust diffuser for a torque-generating turbine, in particular a torque-generating gas turbine, the exhaust diffuser comprising an inner member having an outer surface and an outer member having an inner surface, the inner member and the outer member forming an annular channel, at least a first supporting strut (5) connecting the inner member and the outer member, the first supporting strut (5) extending essentially radially from the inner surface to the outer surface, the first supporting strut comprising a middle section (7) having a first airfoil and an outer section (6) having a second airfoil, and the second airfoil differing from the first airfoil in shape to be able to handle a higher range of angle of attack. Furthermore, it is described a method for manufacturing an exhaust diffuser.

Abstract: The present invention provides an airfoil for a second stage turbine blade having an external surface with first and second sides. The external surface extends spanwise between a hub and a tip and streamwise between a leading edge and a trailing edge of the airfoil. The external surface includes a contour substantially defined by Table 1 as listed in the specification.
