摘要： A turbine disc 202 having a radius and a circumference is provided. The turbine disc includes a central aperture 402 and a plurality of cooling channels 316, 414 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 424, a radially outer end 426, and a lengthwise axis 422 that is curved between the radially inner end and the radially outer end.
