摘要：
A combustion assembly 50 has a combustion chamber 62 and a fuel injector assembly 200 coupled to an outer casing 64 and a liner assembly 54. A fuel injector body 203 has a first inlet opening 221 and a second inlet opening (222 Fig. 5) spaced apart from one another along a first direction (91 Fig. 5). The body has a fuel-oxidizer mixing passage (207 Fig. 9) extended along a second direction (92 Fig. 5) at least partially orthogonal to the first direction, and the first inlet opening, the second inlet opening, and an outlet opening 205 (a, b) are each fluidly connected with the fuel-oxidizer mixing passage. In use, the first inlet opening and the second inlet opening admit a flow of oxidizer, such as air, to the fuel-oxidizer mixing passage, and deliver a fuel/oxidant mixture 186 out of the outlet and into the combustion chamber. The outlet opening may be a slot at least partially orthogonal to the first direction and the second direction. The body may further include a fuel passage (209 Fig. 10) upstream of the fuel-oxidizer mixing passage. The fuel injector assembly provides a relatively shorter fuel injector that is less prone to coking or aero/thermal loading.

WHAT IS CLAIMED IS:
1. A fuel injector assembly, the fuel injector assembly comprising:
a body defining a first inlet opening and a second inlet opening spaced apart from one another along a first direction, wherein the body further defines a fuel- oxidizer mixing passage therewithin extended along a second direction at least partially orthogonal to the first direction, and wherein the first inlet opening and the second inlet opening are each in fluid communication with the fuel-oxidizer mixing passage, and further wherein the body defines an outlet opening at the fuel-oxidizer mixing passage at a distal end relative to the first inlet opening and the second inlet opening, wherein the first inlet opening and the second inlet opening are each configured to admit a flow of oxidizer to the fuel-oxidizer mixing passage, and wherein the fuel-oxidizer mixing passage is configured to provide a flow of fuel- oxidizer mixture to a combustion chamber via the outlet opening.
2. The fuel injector assembly of claim 1, wherein the body defines the fuel-oxidizer mixing passage extended along the second direction between the first inlet opening and the second inlet opening.
3. The fuel injector assembly of claim 1 or 2, wherein the body defines the outlet opening extended at least partially along a third direction orthogonal to the first direction and the second direction.
4. The fuel injector assembly of claim 3, wherein the body defines the outlet opening as a slot extended at least partially orthogonal to the first direction and the second direction.
5. The fuel injector assembly of any of claims 1 to 4, wherein the body comprises a first wall and a second wall spaced apart from one another along the first direction, and wherein the first inlet opening is defined through the first wall and the second inlet opening is defined through the second wall.
6. The fuel injector assembly of claim 5S, wherein the fuel-oxidizer mixing passage is defined between the first wall and the second wall.
7. The fuel injector assembly of claim 5 or 6, the body further defining a third inlet opening through one or more of the first wall or the second wall, wherein the third inlet opening is in fluid communication with the fuel-oxidizer mixing
passage, and further wherein the third inlet opening is configured to provide a flow of oxidizer to the fuel-oxidizer mixing passage.
8. The fuel injector assembly of claim 7, wherein the third inlet opening is disposed adjacent to one or more of the first inlet opening or the second inlet opening along the second direction.
9. The fuel injector assembly of any of claims 1 to 8, wherein the first inlet opening and the second inlet opening each define an inlet passage in fluid communication with the fuel-oxidizer mixing passage.
10. The fuel injector assembly of claim 9, wherein the inlet passage is disposed at an acute angle relative to the first direction and the second direction.
11. The fuel injector assembly of any of claims 1 to 10, wherein the body further defines a fuel passage extended in fluid communication with the fuel-oxidizer mixing passage, wherein the fuel passage is configured to provide a flow of fuel to the fuel-oxidizer mixing passage.
12. The fuel injector assembly of claim 11, wherein the fuel passage is extended along the second direction upstream of the fuel-oxidizer mixing passage.
13. The fuel injector assembly of claim 11 or 12, wherein the body defines a fuel passage exit opening directly between the first inlet opening and the second inlet opening along the first direction.
14. The fuel injector assembly of any of claims 11 to 13, wherein the body comprises a third wall extended at least partially along the second direction, and wherein the fuel passage is defined through the third wall.
15. The fuel injector assembly of any of claims 11 to 14, wherein the body defines a plurality of first inlet openings and second inlet openings each in adjacent arrangement along a third direction orthogonal to the first direction and the second direction.
16. The fuel injector assembly of claim 15, wherein the body defines a plurality of third inlet openings between one or both of the first inlet openings or second inlet openings along the third direction.
17. The fuel injector assembly of claim 16 when dependent on claim 14, wherein the third inlet opening is separated from one or both of the first inlet opening
or the second inlet opening by the third wall extended at least partially along the second direction.
18. The fuel injector assembly of any of claims 15 to 17, wherein the body defines a plurality of fuel passages in adjacent arrangement along the third direction, and wherein the body defines a third inlet passage extended at least partially along the first direction, wherein the third inlet passage is defined between a pair of the third wall.
19. The fuel injector assembly of claim 18, wherein the third inlet passage is disposed upstream of a fuel passage exit opening through which a flow of fuel is provided to the fuel-oxidizer mixing passage.
20. The fuel injector assembly of claim 18 or 19, wherein the body further defines a fourth passage extended in fluid communication with the combustion chamber, and wherein a fourth wall separates the fourth passage and the fuel-oxidizer mixing passage.
