Abstract
An assembly is provided for a turbine engine. This turbine engine assembly includes a flowpath duct, a fuel injector assembly and a secondary duct. The flowpath duct includes a flowpath. The fuel injector assembly includes an inner flow passage. The fuel injector assembly is configured to mix fuel with first gas within the inner flow passage to provide a fuel-gas mixture. The fuel injector assembly is configured to direct a jet of the fuel-gas mixture into the flowpath. The secondary duct is configured to direct second gas into the flowpath about the jet of the fuel-gas mixture.

An assembly for a turbine engine, comprising:
- a flowpath duct including a flowpath;
- a fuel injector assembly including an inner flow passage, the fuel injector assembly configured to mix fuel with first gas within the inner flow passage to provide a fuel-gas mixture, and the fuel injector assembly configured to direct a jet of the fuel-gas mixture into the flowpath;
- and
- a secondary duct configured to direct second gas into the flowpath about the jet of the fuel-gas mixture.
An assembly for a turbine engine, comprising:
- a flowpath duct including a flowpath;
- and
- a fuel injector assembly including an inner flow passage;
- the fuel injector assembly configured receive first gas from a first gas source, receive second gas from a second gas source, and mix fuel with the first gas and the second gas within the inner flow passage to provide a fuel-gas mixture;
- and
- the fuel injector assembly is configured to direct a jet of the fuel-gas mixture into the flowpath.
An assembly for a turbine engine, comprising:
- a flowpath duct including a flowpath;
- a protrusion connected to the flowpath duct and projecting radially into the flowpath towards a centerline of the flowpath duct;
- and
- a fuel injector assembly including an inner flow passage;
- the fuel injector assembly configured to inject fuel into the inner flow passage for mixing with first gas within the inner flow passage to provide a fuel-gas mixture;
- and
- the fuel injector assembly configured to direct a jet of the fuel-gas mixture into the flowpath at a location downstream of and aligned with the protrusion.
