Combustor

摘要

A gas turbine engine combustor (20) has forward bulkhead (36) extending between inboard and outboard walls (32, 34) and cooperating therewith to define a combustor interior volume or combustion chamber (30). At least one of the walls has an exterior shell and an interior shell including a number of panels. Each panel has interior and exterior surfaces (102, 104) and a perimeter having leading and trailing edges (106, 108) and first and second lateral edges (110, 112). A number of cooling passageways (140) have inlets on the panel exterior surface (104) and outlets on the panel interior surface (102). A rail (114) protrudes from the exterior surface and is recessed from the leading edge (106) along a majority of the leading edge (106).
