Claims
- 1. A gas turbine engine comprising:a compressor; a combustor mounted downstream of said compressor and a power turbine mounted downstream of said combustor; a compressor turbine having an outlet and mounted downstream of said power turbine for producing power for driving said compressor, said compressor turbine being mechanically coupled to said compressor to transmit said power to said compressor and said compressor turbine rotating in a direction opposite to the direction of rotation of said turbine power turbine; a temperature control system for controlling the temperature at said outlet of said compressor turbine; a fuel supply control system for supplying fuel for burning said fuel in said combustor; a drive motor coupled to said compressor to adjust compressor rotation during low fuel operation; a motor control system having a motor power-up module, said motor power-up module having an input connected to said fuel supply control system and an output, said motor control system also having a motor power output control module, said motor power output control module having a first input connected to said motor power-up module, a second input and an output which is connected to said drive motor; and a temperature sensor positioned at said outlet of said compressor turbine and connected to said second input of said motor power output control module.
- 2. The gas turbine engine of claim 1, wherein said gas turbine engine further comprises a heater for supplying heat to said combustor, and means for controlling said heater.
- 3. The gas turbine engine of claim 2, wherein said means for controlling said heater is said motor power-up module having a second output which is connected to said heater.
- 4. The gas turbine engine of claim 1, wherein said gas turbine engine further comprises a heater to supply heat to said combustor, and a motor power-up module connected to said heater control said heater.
