主权项

1. A gas turbine engine system, comprising:
a compressor forming a source of pressurized air; a first combustor in fluid communication with said compressor and configured to receive working fluid consisting of pressurized air directly from the compressor prior to the working fluid passing through a heat addition component or an expansion component; a second combustor in fluid communication with said compressor in parallel with said first combustor and configured to receive working fluid consisting of pressurized air directly from the compressor prior to the working fluid passing through a heat addition component or an expansion component; a first turbine in fluid communication with and downstream of said first combustor; a second turbine in fluid communication with said second combustor; and a third turbine in fluid communication with said second combustor, wherein said third turbine is on a different spool than said second turbine; wherein the second combustor, the second turbine, and the third turbine are configured as an auxiliary engine, wherein the auxiliary engine does not include a compressor.
