Abstract
Problems involving the cooling of a front turbine shroud having a radial section 110 and an axial section 112 connected by a radius 114 and employed in a turbine engine are minimized or eliminated by telescoping the radially outer wall 34 of an annular combustor 26 into the axial section 112 and radially spacing the same inwardly therefrom. An inlet 128 in fluid communication with the compressed air source of the turbine extends to a swirling strip 130 which between the radially outer wall 34 and the axial section 112 and generates a film of cooling air and applies it to the radius 114 of the front shroud 27 to cool the same.
