| description | An embodiment of a torch igniter (10; 110; 410) for a combustor (24) of a gas turbine engine comprises a combustion chamber (16) oriented about an axis (A-A), a cap defining an axially upstream end of the combustion chamber (16) and oriented about the axis, a tip defining an axially downstream end of the combustion chamber, a structural wall (36) coaxial with and surrounding the igniter wall (38), an outlet passage (40) defined by the igniter wall within the tip, and a cooling system. The cooling system comprises an air inlet (62) formed within the structural wall (36), a first flow path disposed between the structural wall and the igniter wall, and an aperture (680) extending through the igniter wall transverse to the flow direction. The aperture directly fluidly connects the first flow path to the combustion chamber. |
