Classification: CPC F  Y | IPC F

Claim 0:
1. An engine system, comprising:
a compressor section comprising a compressor rotor;
a combustor section comprising a combustion chamber;
a turbine section comprising a turbine rotor;
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; and
a fluid source configured to direct gas comprising oxygen 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.
