Classification: CPC F  B | IPC B  F

Claim 13:
14. The turbine module of claim 12, wherein the internal manifold is comprised of:
a primary 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 extending along the suction side of each blade of the plurality of blades, and at least one of:
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/or
a tertiary 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,
wherein the primary cooling channel and the at least one of the secondary cooling channel and/or the tertiary cooling channel combine to form a main cooling channel at a radially inward position before the central nose manifold.
