Patent ID: 8327644

Claim:
A gas turbine engine comprising: an engine housing rotatably supporting a shaft assembly on a bearing assembly; a combustion chamber encased with said engine housing; a compressor coupled to said shaft assembly for rotation about a longitudinal axis, said compressor in fluid communication with said combustion chamber; a turbine coupled to said shaft assembly for rotation about said longitudinal axis, said turbine in fluid communication with said combustion chamber; and a fuel delivery system for delivering an air-fuel mixture to said combustion chamber, said fuel delivery system including: a fuel slinger assembly rotatably supported on said shaft assembly including a slinger body and a slinger impeller, said slinger impeller having a discharge passage in fluid communication with said combustion chamber; and a fuel deflector fixedly supported within said engine housing, said fuel deflector having a inner surface spaced apart from and facing an outer surface of said slinger body to form a fuel delivery channel, said fuel delivery channel beginning at an inlet in fluid communication with a fuel feed tube, diverging along said longitudinal axis and terminating at an outlet adjacent said discharge passage of said slinger impeller, and wherein at least one of said inner and outer surfaces having a contoured surface formed therein.
