Abstract
An engine system is provided that includes an engine core assembly and a fuel system. The engine core assembly includes a core flowpath, a core compressor section, a core combustor section and a core turbine section. The core flowpath extends through the core compressor section, the core combustor section and the core turbine section from an inlet into the core flowpath to an exhaust from the core flowpath. The core compressor section includes a core compressor rotor. The combustor section includes a combustor. The fuel system includes a fuel flowpath, a fuel turbine section and a fuel injector. The fuel flowpath extends through the fuel turbine section to the fuel injector. The fuel turbine section includes a fuel turbine rotor coupled to and rotatable with the core compressor rotor. The fuel injector is configured to direct fuel received from the fuel flowpath into the combustor.
