  • Rotor blade root section with cooling passage and method for supplying cooling fluid to a rotor blade
    Patent number: 9664051
    Abstract: A root section of a rotor blade for interacting with working fluid upon rotating the rotor blade is provided. The root section includes a curved cooling passage for guiding a cooling fluid within the root section. A cooling fluid entry plenum has an entry aperture for introducing the cooling fluid into the cooling passage. A platform is located at a radially outer end of the root section. The curved cooling passage penetrates through the platform, and the following condition is satisfied at least in a portion of a radial extent of the cooling passage: 0.25*dr<rc<1.5*dr, where dr is a radial distance in the radial direction between the platform of the root section and the aperture of the entry plenum and rc is the radius of curvature of the curved cooling passage.
