Field: Engines, pumps, turbines (Mechanical engineering)
Classification: CPC F  Y | IPC F

Claim 1:
2. An engine system, comprising:
a compressor section;
a combustor section comprising a combustion chamber;
a turbine section;
a flowpath extending sequentially through the compressor section, the combustor section and the turbine section;
a flow regulator configured to open a section of the flowpath extending through the compressor section to the combustion chamber during a first mode of operation, the flow regulator configured to at least substantially close the section of the flowpath extending through the compressor section to the combustion chamber during a second mode of operation to limit flow from the compressor section to the combustion chamber, wherein during the second mode of operation a turbine rotor of the turbine section is not rotated by flow provided from the compressor section;
wherein the compressor section and the turbine section are configured as a turbo-compressor during the second mode of operation, and the combustor section is non-operational during the second mode of operation; and
a fluid source configured to direct fluid source gas into the combustion chamber, during the second mode of operation, independent of the section of the flowpath extending through the compressor section to the combustion chamber.
