Abstract
Abstract A manifold spray assembly having an annular housing adapted to be removably secured to the inlet end of a gas turbine and support a plurality of nozzle assemblies adapted to spray a fluid into the intake airstream of a gas turbine compressor for cleaning, preservation, or thrust augmentation purposes. The nozzles are recessed within the annular housing so as not to interfere with the gas turbine intake airflow and are connected to a fluid inlet fitting through connector blocks and conduits.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
130 words
In a gas turbine engine, a spray apparatus comprising, in combination, housing means having an axial bore being located on a gas turbine for passage of the gas turbine intake air stream through said axial bore, and spray means carried by said housing means in noninterfering relationship to said intake air stream for spraying fluid into said air intake airstream, said spraying means comprising a plurality of nozzles recessed within said housing means so as not to protrude into said axial bore, each said nozzle having an orifice adapted to spray fluid generally radially inwardly of and axially along said housing means axial bore with the interior surface of said housing means having a groove adjacent each said nozzle adapted to allow passage of said axially directed spray of fluid.
Claim 2
Dependent Claim
130 words
In a gas turbine engine, a spray apparatus comprising, in combination, housing means having an axial bore being located on a gas turbine for passage of the gas turbine intake air stream through said axial bore, and spray means carried by said housing means in noninterfering relationship to said intake air stream for spraying fluid into said air intake airstream, said spraying means comprising a plurality of nozzles recessed within said housing means so as not to protrude into said axial bore, each said nozzle having an orifice adapted to spray fluid generally radially inwardly of and axially along said housing means axial bore with the interior surface of said housing means having a groove adjacent each said nozzle adapted to allow passage of said axially directed spray of fluid.
Claim 3
Dependent Claim
51 words
The spray apparatus recited in claim 1 wherein said housing means includes a plurality of apertures extending generally radially from said axial bore, each said nozzle located in one of said apertures with an inner terminal position whose radius from said axial bore is at least equal to the bore radius.
Claim 4
Dependent Claim
36 words
The spray apparatus recited in claim 2 wherein each said nozzle includes an enlarged portion outwardly of said housing means sized to prohibit passage of said nozzle through its respective aperture and into said axial bore.
Claim 5
Dependent Claim
68 words
The spray apparatus recited in claim 1 wherein the means for spraying fluid into said intake airstream comprises a plurality of nozzle assemblies, each said nozzle assembly having a first nozzle and a second nozzle secured to a nozzle support block and recessed within said housing means, eacH said nozzle having an orifice adapted to spray fluid generally radially inwardly and axially along said housing means axial bore.
Claim 6
Dependent Claim
67 words
The spray apparatus recited in claim 4 which further includes means for delivering fluid to each said nozzle, said means comprising an inlet fitting having a first inlet and a second inlet, first conduit means for delivery of fluid from said first inlet to each of said first nozzles and second conduit means for delivery of fluid from said second inlet to each of said second nozzles.
Claim 7
Dependent Claim
124 words
A spray apparatus for use on a gas turbine, said apparatus comprising, in combination, an annular housing having an axial bore, spraying means carried by said housing, said spraying means comprising a plurality of nozzles recessed within said housing so as not to protrude into said axial bore, each said nozzle having an orifice adapted to spray fluid generally radially inward of and axially along said housing axial bore, with the interior surface of said housing having a groove adjacent each said nozzle adapted to allow passage of said axially directed spray of fluid, means for delivering fluid to said nozzles, and means for securing said housing through a gas turbine in a position for delivery of a fluid spray into said gas turbine.
Claim 8
Dependent Claim
124 words
A spray apparatus for use on a gas turbine, said apparatus comprising, in combination, an annular housing having an axial bore, spraying means carried by said housing, said spraying means comprising a plurality of nozzles recessed within said housing so as not to protrude into said axial bore, each said nozzle having an orifice adapted to spray fluid generally radially inward of and axially along said housing axial bore, with the interior surface of said housing having a groove adjacent each said nozzle adapted to allow passage of said axially directed spray of fluid, means for delivering fluid to said nozzles, and means for securing said housing through a gas turbine in a position for delivery of a fluid spray into said gas turbine.
Claim 9
Dependent Claim
53 words
The spray apparatus recited in claim 6 wherein said housing includes a plurality of apertures extending generally radially from said axial bore, each said nozzle located in one of said apertures with an inner terminal position whose radius from the axis of said axial bore is at least equal to the bore radius.
Claim 10
Dependent Claim
36 words
The spray apparatus recited in claim 7 wherein each said nozzle includes an enlarged portion outwardly of said housing means sized to prohibit passage of said nozzle through its respective aperture and into said axial bore.
