Undesirably high and damaging temperature gradients resulting from hot spots in combustors 26 for housing a hot gas generating oxidation reaction are avoided in a construction including a combustor housing haivng a wall 32, 34, 39 with an interior surface defining a combustion space 38, 40 and an exterior surface thereof and provided with an outlet 36. A plenum 44, 80, 82 surrounds the combustor 26 and a fuel injector 50, 52 is provided for introducing a fuel to be oxidized into the combustion space 38, 40. Oxidant inlets 54 to the combustion space 38, 40 are provided and various structures including the plenum 44, 80, 82 flow cooling gas in a path about the exterior surface of the walls, 32, 34, 39 to cool the combustor housing. Trip strips 114, 118 are located on the exterior surface of the walls 32, 34, 39 and extend into the cooling gas flow path and are located to minimize the temperature gradient between points along those walls 32, 34 and 39.

A turbine engine comprising: a rotary compressor; a turbine wheel rotatable about an axis and coupled to the rotary compressor to drive the same; a nozzle for directing gases of combustion at said turbine wheel to cause the same to rotate; an annular combustor centered on said axis and having an outlet connected to said nozzle, said combustor having at least one wall having an interior side and an exterior side and provided with spaced rows of apertures to produce a film of cooling air on said interior side from air entering said combustor through said apertures; a plenum substantially surrounding said combustor and in fluid communication with said compressor and for delivering compressed air therefrom to said apertures; and trip strips on said exterior side between said rows of apertures and directed toward, but not to, said plenum, said trip strips being located to minimize the temperature gradient between spaced locations located in turn between adjacent rows of apertures.
