Classification: CPC F  B | IPC B  F

Claim 2:
3. The turbine rotor of claim 2, wherein the internal manifold comprises:
a primary cooling channel fluidically connected to the impingement jets, extending radially inward from the impingement jets between the base and the rear surface of the turbine rotor, and extending along the suction side of each blade of the plurality of blades;
a secondary cooling channel fluidically connected to the impingement jets and extending radially inward from the impingement jets between the base and the rear surface of the turbine rotor; and
a tertiary cooling channel fluidically connected to the impingement jets and extending radially inward from the impingement cooling jets between the base and the rear surface of the turbine rotor,
wherein the primary cooling channel, the secondary cooling channel, and the tertiary cooling channel combine to form a main cooling channel at a radially inward position before the central nose manifold.
