The expense of fabricating an annular combustor for use with a small diameter gas turbine engine is minimized in a construction including a bell-shaped housing 52, an axially extending sleeve 66 within the housing 52, an annular liner 74 within the housing 52 and about the sleeve 66 and including inner, outer and radial walls 80, 76, 78, respectively, spaced from the sleeve 66 and the housing 52 and all being formed of sheet metal. A circular fuel manifold 108 with angularly spaced fuel dispensing openings 122 is disposed between the housing 52 and the outer wall 76 and a plurality of open ended, elongated tubes 112 extend through the outer wall 76 and are in fluid communication with respective openings 122 in the fuel manifold 108 to introduce air and fuel generally tangentially into the liner 74.

An annular combustor for a gas turbine comprising: an annular outer wall; an annular inner wall within said outer wall and separated therefrom by an annular space; a generally radially extending wall interconnecting said inner and outer walls; a housing about at least said outer and radial walls and spaced therefrom to define a compressed air annulus exterior of said outer and radially extending walls and adapted to be connected to a compressor for a turbine engine; fuel injectors extending through the outer wall into the space between the inner and outer walls and oriented to inject fuel in a generally tangential direction within said space; and means for directing a oxidant into said space in said generally tangential direction whereby fuel and air swirl within said space; said outer wall being characterized by being imperforate in the section thereof that is in alignment with the path of fuel injection and further characterized by the absence of any means for flowing an air stream of air from said compressed air annulus over said section on the inner side of said outer wall.
