Abstract:
1. A turbine comprising: a. a rotor; b. a casing circumferentially surrounding at least a portion of the rotor, wherein the rotor and the casing at least partially define a gas path through the turbine; c. a last stage of rotating blades circumferentially arranged around the rotor, wherein each rotating blade of the last stage of rotating blades includes a downstream swept portion defined along a radial span of the rotating blade, wherein the downstream swept portion extends from a point defined along the span that is radially outward from the rotor to a tip of the rotating blade, wherein a radial length of the rotating blade continuously increases along a chord line of the rotating blade from a leading edge portion of the rotating blade to a trailing edge portion of the rotating blade.
