Official abstract text for this publication.
A jet engine includes an inlet and a combustor. the inlet takes in air. The combustor combusts fuel with the air. The combustor (12) includes an injector (20) having a plurality of openings (31a, 31b) from which the fuel is injected. The plurality of openings (31a, 31b) are arranged in a direction perpendicular to a direction of a flow path of the air in the combustor (12). The plurality of openings (31a, 31b) include two types of openings different in area.
Opening claim text (preview).
The invention claimed is: 1. A jet engine comprising: an inlet configured to take in air; and a combustor configured to combust fuel by using the air; wherein the combustor comprises: an injector having an opening from which the fuel is injected, wherein the opening is extended in a direction perpendicular to a direction of an air flow path in the combustor, wherein the opening has a first part and a second part which are alternately arranged in the direction perpendicular to the direction of the air flow path, and wherein a shortest width of the first part in the direction of the air flow path is shorter than a longest width of the second part in the direction of the air flow path. 2. The jet engine according to claim 1 , wherein a width, comprising the shortest width and the longest width of the opening in the direction of the air flow path is wavily changed along the direction perpendicular to the direction of the air flow path.
