1. A gas turbine engine having a center axis and comprising:
a compressor; a prediffuser pneumatically coupled to the compressor, the prediffuser including a prediffuser exit, an outer wall, and an inner wall; and a system for mixing fuel and air, the system including
a flow splitter located proximate to the prediffuser exit and configured to separate a center flow away from an outer flow and an inner flow of compressed air from the prediffuser exit, the center flow having a higher average velocity than the outer flow and the inner flow,a center duct including a center duct inlet and a center duct exit, the center duct configured to pneumatically couple with a portion of the prediffuser exit offset from the outer wall and the inner wall at the center duct inlet, the center duct further configured to receive the center flow from the prediffuser exit and to route the center flow to a combustion chamber of the gas turbine engine, andan axial mixer within the center duct, the axial mixer configured to direct the center flow to mix with fuel provided by an injector. |
