ABSTRACT:
A gas turbine engine has a turbine mounted downstream of a compressor and a compressor turbine mounted downstream of the turbine for driving the compressor. The compressor turbine has a rotor disk that is mechanically coupled to the compressor and rotates in a direction opposite to the direction of rotation of the turbine rotor disk. A heat exchanger has a first circuit connected to the compressor turbine and a second circuit connected between the compressor and the turbine. An electric load for taking off a fraction of power produced by the compressor turbine includes an electric generator that is mechanically coupled to the compressor turbine. An electric load controller changes the fraction of power produced by the compressor turbine based on readings from the temperature sensor located in the engine.
