The present disclosure is directed to a gas turbine engine defining a radial direction, a circumferential direction, an axial centerline along a longitudinal direction. The gas turbine engine defines an upstream end and a downstream end along the longitudinal direction and includes a turbine frame defined around the axial centerline. The turbine frame includes a first bearing surface, a second bearing surface, and a third bearing surface. The first bearing surface corresponds to a first turbine rotor, the second bearing surface corresponds to a second turbine rotor, and the third bearing surface corresponds to a third turbine rotor, and each turbine rotor is independently rotatable.
A gas turbine engine, wherein the gas turbine engine defines a radial direction, a circumferential direction, an axial centerline along a longitudinal direction, and wherein the gas turbine engine defines an upstream end and a downstream end along the longitudinal direction, the gas turbine engine comprising:
A method of operating a gas turbine engine with an interdigitated turbine section, wherein the engine comprises a fan rotor, an intermediate pressure compressor, a high pressure compressor, a combustion section, and a turbine section in serial flow arrangement, wherein the turbine section comprises, in serial flow arrangement, a high speed turbine rotor, a turbine frame, a first stage of a plurality of outer shroud airfoils of a low speed turbine rotor, an intermediate speed turbine rotor, and one or more additional stages of the low speed turbine rotor, the low speed turbine rotor coupled to the fan rotor via a low pressure shaft, the intermediate speed turbine rotor coupled to the intermediate pressure compressor via an intermediate pressure shaft, and the high speed turbine rotor coupled to the high pressure compressor via a high pressure shaft, the method comprising:
