Abstract: A turbine disc assembly is provided. The turbine disc assembly includes a first rotor disc, a second rotor disc, and a spacer disc coupled between the first and second rotor discs along an axis to define a plenum. The spacer disc has an inner surface with a radius from the axis. A first cooling channel defined between the first rotor disc and the spacer disc is in flow communication with the plenum. The second rotor disc includes a deflector having a deflection surface positioned within the plenum such that the deflection surface is oriented towards the first cooling channel at an acute angle relative to the radius of the inner surface of the spacer disc.

Abstract: A turbine disc having a radius and a circumference is provided. The turbine disc includes a central aperture and a plurality of cooling channels circumferentially spaced about the central aperture such that the cooling channels are in flow communication with the central aperture. Each of the cooling channels has a radially inner end, a radially outer end, and a lengthwise axis that is curved between the radially inner end and the radially outer end.
