Abstract
A gas turbine engine combustor includes radially spaced outer and inner liners disposed coaxially about an engine longitudinal centerline axis with each liner having forward and aft ends. An annular dome is fixedly joined to the forward ends of the outer and inner liners. The outer liner has a substantially uniform thickness and is arcuate in a longitudinal plane from the forward to aft ends for providing buckling resistance of the outer liner.
Claims12
A gas turbine engine combustor having an axial centerline axis comprising:
- an annular outer liner disposed coaxially about said centerline axis and having a forward end and an aft end;
- an annular inner liner disposed coaxially about said centerline axis and spaced radially inwardly from said outer liner to define a combustion zone therebetween and having a forward end and an aft end;
- an annular dome fixedly joined to said forward ends of said outer and inner liners, wherein said dome is a double annular dome having apertures for receiving two radially spaced rows of circumferentially spaced carburetors;
- stationary casing means for supporting said inner and outer liners to inner and outer casings, respectively;
- and
- said outer liner having a substantially uniform thickness from said forward to said aft ends and being arcuate in a longitudinal plane from said forward to said aft ends for providing buckling resistance of said outer liner.
