Abstract
Abstract A new tubing (or electrical lead) support is combined with a new gas turbine engine control and accessory mounting pad, which also serves to communicate fluids/electrical signals to such controls and accessories to provide a more compact and easily maintained gas turbine engine. Tubing is permanently or semi-permanently bonded to the engine casing and the tubing is terminated in a shear face pad which provides ''''plug in'''' mounting pads for the controls and accessories.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
104 words
In a gas turbine engine of the type including a casing defining an internal flow path, a compressor, a combustion system, a turbine for driving the compressor, and a plurality of casing-mounted controls for regulating the operation of said engine, the improvement comprising: a combination mounting pad and fluid/electrical signal communicating device for one of said engine controls, said device including a first face for receiving a mating face of the control and a second face having one or more tubes extending therefrom, said first face including one or more openings which cooperate with said tubes to communicate fluid/electrical signals to the mounted control.
Claim 2
Dependent Claim
104 words
In a gas turbine engine of the type including a casing defining an internal flow path, a compressor, a combustion system, a turbine for driving the compressor, and a plurality of casing-mounted controls for regulating the operation of said engine, the improvement comprising: a combination mounting pad and fluid/electrical signal communicating device for one of said engine controls, said device including a first face for receiving a mating face of the control and a second face having one or more tubes extending therefrom, said first face including one or more openings which cooperate with said tubes to communicate fluid/electrical signals to the mounted control.
Claim 3
Dependent Claim
33 words
The improved mounting pad recited in claim 1 further characterized in that said first face includes a second set of openings for receiving means for rigidly connecting the control to said first face.
Claim 4
Dependent Claim
19 words
The improved mounting pad recited in claim 2 further including means for connecting said device to the engine casing.
Claim 5
Dependent Claim
21 words
The improved mounting pad recited in claim 2 in combination with means for permanently connecting said tubes to the engine casing.
Claim 6
Dependent Claim
25 words
The combination recited in claim 4 wherein said tube connecting means includes a trough formed on the exterior of said casing for receiving said tubes.
Claim 7
Dependent Claim
26 words
The combination recited in claim 5 wherein said tubes are positioned within said trough and are bonded to said casing by means of an epoxy filler.
Claim 8
Dependent Claim
20 words
The combination recited in claim 4 wherein said tubes are connected to said casing by means of an epoxy cement.
Claim 9
Dependent Claim
31 words
The combination recited in claim 4 wherein said tubes are connected to said casing by means of a flexible cover which surrounds said tubes and which is attached to said casing.
Claim 10
Dependent Claim
18 words
The combination recited in claim 8 wherein said flexible cover includes an opening for removal of said tubes.
Claim 11
Dependent Claim
74 words
In a gas turbine engine with an exterior casing a mounting pad for a gas turbine engine control comprising a first face for receiving a mating face of said control, said first face including means for connecting the control thereto, a second face extending generally perpendicular to said first face and having one or more fluid communicating tubes extending therefrom, and means for connecting said mounting pad to the exterior casing of the engine.
Claim 12
Dependent Claim
74 words
In a gas turbine engine with an exterior casing a mounting pad for a gas turbine engine control comprising a first face for receiving a mating face of said control, said first face including means for connecting the control thereto, a second face extending generally perpendicular to said first face and having one or more fluid communicating tubes extending therefrom, and means for connecting said mounting pad to the exterior casing of the engine.
Claim 13
Dependent Claim
21 words
The mounting pad recited in claim 10 wherein said means for connecting said pad to the casing provide a rigid connection.
Claim 14
Dependent Claim
31 words
The mounting pad recited in claim 11 wherein said connecting means include one or more bosses extending from said casing for receiving bolts which attach said mounting pad to said casing.
Claim 15
Dependent Claim
28 words
The mounting pad recited in claim 10 wherein said connecting means provide a flexible mount whereby slight movement of said pad with respect to said casing is possible.
Claim 16
Dependent Claim
29 words
