Abstract
Abstract A rotating slinger fuel injector for turbine engines is provided with a plurality of radial holes for distributing and mixing fuel and air throughout the combustor. Fuel is supplied from a stationary fuel manifold through fuel ports in a rotating slinger which distributes the fuel in a plurality of planes throughout the combustor. Air is channeled from the compressor rotor through radially and axially angled air ports provided in the slinger so as to distribute air in a plurality of planes which intersect the planes of distributed fuel at various points throughout the interior combustor. Thus the combustion intensity and efficiency is greatly increased.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
140 words
A turbine engine having a support housing, a shaft rotatably secured within said support housing, an air compressor rotatably mounted in said housing and having an inlet and an outlet, a combustor in said housing, said combustor having a chamber fluidly connected with the outlet of the compressor, means for supplying fuel to the combustor chamber, said last-mentioned means comprising a slinger type fuel injector secured to said shaft having an annular housing and a plurality of radial bores adapted to provide a plurality of axially spaced planes of fuel and air introduction into said combustor chamber, a stationary fuel manifold spaced radially inwardly from said injector housing and in fluid communication with a first portion of said radial bores, and air passage means for fluidly connecting the outlet of the compressor to a second portion of said radial bores.
Claim 2
Dependent Claim
140 words
A turbine engine having a support housing, a shaft rotatably secured within said support housing, an air compressor rotatably mounted in said housing and having an inlet and an outlet, a combustor in said housing, said combustor having a chamber fluidly connected with the outlet of the compressor, means for supplying fuel to the combustor chamber, said last-mentioned means comprising a slinger type fuel injector secured to said shaft having an annular housing and a plurality of radial bores adapted to provide a plurality of axially spaced planes of fuel and air introduction into said combustor chamber, a stationary fuel manifold spaced radially inwardly from said injector housing and in fluid communication with a first portion of said radial bores, and air passage means for fluidly connecting the outlet of the compressor to a second portion of said radial bores.
Claim 3
Dependent Claim
35 words
The invention as defined in claim 1 wherein said fuel manifold comprises an annular housing having a plurality of radial bores, each said bore aligned to fluidly communicate with a radial bore in said injector.
Claim 4
Dependent Claim
39 words
The invention as defined in claim 1 wherein said fuel manifold comprises a plurality of axially aligned tubes, each tube having at least one radial bore aligned to fluidly communicate with at least one radial bore in said injector.
Claim 5
Dependent Claim
26 words
The invention as defined in claim 1 wherein each radial bore in said injector is angled with respect to a radius of said annular injector housing.
Claim 6
Dependent Claim
26 words
The invention as defined in claim 1 wherein each radial bore in said injector is angled with respect to the axis of said annular injector housing.
Claim 7
Dependent Claim
42 words
The invention as defined in claim 1 wherein the radial bores in said annular injector housing are arranged in axially spaced rows extending around the circumference of said injector housing and wherein alternate rows comprise said first portion of said radial bores.
