Abstract:
1. A turbine engine, comprising: at least one combustor positioned upstream from a rotor assembly including a plurality of blades extending radially from a rotor; a first row of turbine vanes attached to a vane carrier, wherein the turbine vanes each extend radially inward and terminate proximate to the rotor assembly; a rotor cooling fluid collection chamber positioned in a rotating portion of the rotor assembly; a fluid channel directing cooling fluids from the rotor cooling fluid collection chamber to a combustor of the turbine engine; and at least one pump mechanically coupled to the rotor assembly for pressurizing a cooling fluid in the rotor cooling fluid collection chamber in the rotor assembly, wherein the at least one pump is positioned downstream of the first row of turbine vanes in the fluid channel that directs cooling fluids from the rotor cooling fluid collection chamber to the combustor.
