AIRFOIL, SLEEVE, AND METHOD FOR ASSEMBLING A COMBUSTOR ASSEMBLY

摘要

An airfoil, a sleeve, and a method for assembling a combustor assembly are provided to optimize the cooling of a combustor liner and a variation member such that the gradient of a reduced temperature exists. A sleeve is used for a combustion assembly. A plurality of air foil protrusions belongs to the sleeve. The air foil protrusion has a structure of guiding a cooling air into a cooling passage of the combustion assembly. A plurality of opposite sidewalls(550,552) are coupled to each other in front and rear end edges(542,546). At least one channel is provided between the opposite sidewalls to guide the cooling air. The channel guides air flowing around air foils(500) in a direction perpendicular to the direction of the air.
