Abstract
Abstract In a turbine engine compressed air is delivered through a diffuser to a burner section and then through a turbine section. A portion of the compressed air from said diffuser is removed by an annular center body manifold and directed by hollow struts inwardly to an annular passageway where the compressed air flow is taken to the forward part of the turbine section. The flow from the annular passageway is then directed into a passageway having directing vanes for imparting a desired velocity and direction to the existing flow so as to be compatible with the rotating turbine disk onto which it flows. This air is then directed to cool blades on that disk and also passed through that disk to be directed to turbine blades on the next disk. The invention herein described was made in the course of or under a contract with the Department of the Air Force.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
241 words
In combination, a turbine engine including an annular inlet section having a first outer wall and a first inner wall, an annular combustion section having a second outer wall connected to said first outer wall and a second inner wall connected to said first inner wall, a turbine section, said turbine section including a turbine rotor, said turbine rotor including a turbine disk mounted for rotation along with turbine blades mounted therearound, an annular manifold located immediately downstream of said annular inlet section, said annular manifold having an outer surface and an inner surface, said annular manifold having an annular inlet for receiving flow from said inlet section, said annular manifold being axially in line with the center of said annular inlet section with said annular inlet of said annular manifold being forwardly into the center of the annular inlet section for receiving flow passing therethrough, said annular combustion section having a third inner wall spaced from said second inner wall providing a first annular passageway, hollow struts extending between the inner surface of said annular manifold and the adjacent end of said first annular passageway, a rotarting annular passageway extending forwardly from said disk, said first annular passageway having its downstream end located adjacent the rotating annular passageway so as to direct cooling air therefrom into the rotating annular passageway, passage means in said disk being in communication with said rotating passageway for directing flow to said blades for cooling.
Claim 2
Dependent Claim
241 words
In combination, a turbine engine including an annular inlet section having a first outer wall and a first inner wall, an annular combustion section having a second outer wall connected to said first outer wall and a second inner wall connected to said first inner wall, a turbine section, said turbine section including a turbine rotor, said turbine rotor including a turbine disk mounted for rotation along with turbine blades mounted therearound, an annular manifold located immediately downstream of said annular inlet section, said annular manifold having an outer surface and an inner surface, said annular manifold having an annular inlet for receiving flow from said inlet section, said annular manifold being axially in line with the center of said annular inlet section with said annular inlet of said annular manifold being forwardly into the center of the annular inlet section for receiving flow passing therethrough, said annular combustion section having a third inner wall spaced from said second inner wall providing a first annular passageway, hollow struts extending between the inner surface of said annular manifold and the adjacent end of said first annular passageway, a rotarting annular passageway extending forwardly from said disk, said first annular passageway having its downstream end located adjacent the rotating annular passageway so as to direct cooling air therefrom into the rotating annular passageway, passage means in said disk being in communication with said rotating passageway for directing flow to said blades for cooling.
Claim 3
Dependent Claim
66 words
A combination as set forth in claim 1 wherein projections extend from the outer surface of said annular manifold outwardly towards the second outer wall of the annular burner section, each projection having an opening extending into the end thereof, means being provided at a plurality of locations for extending through said second outer wall into the openings in said projections for supporting said annular manifold.
Claim 4
Dependent Claim
20 words
A combination as set forth in claim 2 wherein said means for extending into the openings are individually removable pins.
Claim 5
Dependent Claim
102 words
A combination as set forth in claim 1 wherein a burner is located in said annular combustion section, the rearward part of said burner being connected between said second inner wall and said second outer wall and positioned to exhaust into said turbine section, the forward end of said burner having an arm means projecting outwardly therefrom, said arm means having a second opening therethrough, said second opening being aligned radially outwardly from an opening in a projection extending from the outer surface of said annular manifold, said pin means extending through said second opening into its cooperating opening in a projection.
