Abstract (en)
[origin: WO2015193068A1] The invention relates to a turbine blade (1) having an internally cooled turbine airfoil (3), which forms at least one cooling air main channel (19) extending in the longitudinal direction (18) of the turbine blade (1) in order to guide cooling air (23) from a cooling air main channel inlet arranged in a region (24) of a turbine blade root through the turbine blade airfoil (3) in the direction (25) of a turbine blade tip. Inside the at least one cooling air main channel (19), a hollow guide device (3) for guiding additional cooling air (36) is arranged, through which, independently from the cooling air main channel (19), additional cooling air (36) can be introduced into the turbine blade airfoil (3) downstream behind the cooling air main channel inlet.
