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.

A gas turbine comprising: a rotor including compressor blades and turbine blades; an inlet adjacent one side of said compressor blades; a diffuser adjacent the other side of said compressor blades; a nozzle including front and rear shrouds and adjacent said turbine blades for directing hot gases at said turbine blades to cause rotation of said rotor; an annular combustor having radially inner and outer walls connected by a generally radially extending wall about said rotor and having an outlet connected to said nozzle and a primary combustion annulus defined by said walls remote from said outlet, a plurality of fuel injectors to said primary combustion annulus and being substantially equally angularly spaced therearound and configured to inject fuel into said primary combustion annulus in a nominally tangential direction; and means on said radially outer wall and at said outlet for establishing a cooling air stream on said front shroud; said front shroud including a radial section having its outer extremity joined to an axial section by a relatively small radius, said establishing means being located at the junction of said radius and said axial section.
