Abstract
A moving turbine blade includes a blade profile with inner cooling which extends out from a blade platform adjoined by a blade foot, the blade foot engaging with a turbine disk and having a radial cross-section with an area whose width increases towards the blade platform. A moving turbine blade of this type is configured in such a way as to enable the moving blade profile to be lengthened. To this end, the blade foot has a hollowed-out section which opens out in the direction facing away from the platform side and which has a widened cross section in the area of the blade foot whose width increases.
