Patent ID: 8092175

Claim:
A turbine blade, comprising: a profiled blade airfoil that is exposed to a circumflow of an operating gas, the blade airfoil comprising: a leading edge that is exposed to an inflow of the operating gas, and a trailing edge on which the operating gas flows out, the trailing edge extending along a blade airfoil principal axis from a root region of the blade airfoil to a tip region of the blade airfoil opposite to the root region; a first discharge opening arranged in a region of the trailing edge for blowing out a first medium into the operating gas; a first passage system leading to the first discharge opening for guiding the first medium; a second discharge opening arranged in the region of the trailing edge at least partially with a same height as the first discharge opening along the blade airfoil principal axis for blowing out a second medium; and a second passage system connected to the second discharge opening for guiding the second medium that is fed to the turbine blade separately from the first medium, wherein the first discharge opening and the second discharge opening forms an overlapping pair of openings along the blade airfoil principal axis.
