Abstract

A routing plate assembly is provided and includes a gearbox having an aft surface, first and second hydraulic components, a routing plate comprising a forward side affixable to the aft surface of the gearbox, an aft side to which the first and second hydraulic components are affixable and a body. The body is formed to define interfacial pathways by which the gearbox and the first and second hydraulic components are communicative.

First claim

What is claimed is:

1 . A routing plate assembly, comprising:
a gearbox having an aft surface; first and second hydraulic components; a routing plate comprising a forward side affixable to the aft surface of the gearbox, an aft side to which the first and second hydraulic components are affixable and a body, the body being formed to define interfacial pathways by which the gearbox and the first and second hydraulic components are communicative.

2 . The routing plate assembly according to claim 1 , further comprising:
a rotatable propeller shaft; an oil transfer tube, which is extendible from the gearbox, through the routing plate and into the second hydraulic component; and a gas turbine engine configured to generate rotational energy transmittable to the rotatable propeller shaft by the gearbox to drive rotations of the rotatable propeller shaft.

3 . The routing plate assembly according to claim 2 , wherein the first hydraulic component comprises a propeller hydraulic control unit and the second hydraulic component comprises a fluid transfer bearing module.

4 . The routing plate assembly according to claim 3 , wherein the propeller hydraulic control unit comprises:
a gear pump element; a regulator valve; and an electro-hydraulic servo valve.

5 . The routing plate according to claim 3 , wherein the interfacial pathways comprise a lube oil supply pathway running from the gearbox, through the routing plate and into the first hydraulic component.

6 . The routing plate according to claim 3 , wherein the interfacial pathways comprise a pump drive interface running from the gearbox, through the routing plate and into the first hydraulic component.

7 . The routing plate according to claim 3 , wherein the interfacial pathways comprise hydraulic pathways running from the propeller shaft, through the second component, through the routing plate and into the first component.

8 . The routing plate according to claim 3 , wherein the interfacial pathways comprise:
a lube oil supply pathway running from the gearbox, through the routing plate and into the first hydraulic component; a pump drive interface running from the gearbox, through the routing plate and into the first hydraulic component; and oil transfer pathways running from the propeller shaft, through the second component, through the routing plate and into the first component.

9 . The routing plate according to claim 1 , further comprising a transfer tube disposed along one of the interfacial pathways for first and second hydraulic component communication, the transfer tube comprising:
a first portion sealably disposable in the routing plate; and a second portion sealably disposable in the first or second hydraulic component.

10 . A routing plate assembly, comprising:
a gearbox having an aft surface; first and second hydraulic components; a routing plate comprising a forward side affixable to the aft surface of the gearbox, an aft side to which the first and second hydraulic components are affixable and a body, the body being formed to define a first interfacial pathway by which the gearbox and the first hydraulic component are mechanically communicative and second interfacial pathways by which the gearbox and the first and second hydraulic components are fluidly communicative.

11 . The routing plate according to claim 10 , further comprising a transfer tube disposed along one of the interfacial pathways for first and second hydraulic component fluid communication, the transfer tube comprising:
a first portion sealably disposable in the routing plate; and a second portion sealably disposable in the first or second hydraulic component.

12 . A routing plate for hydraulic lines, the routing plate comprising:
a forward side affixable to an aft gearbox surface; an aft side to which first and second hydraulic components are affixable; and a body extending between the forward and aft sides, the body being formed to define interfacial pathways by which the gearbox and the first and second hydraulic components are communicative.

13 . The routing plate according to claim 12 , wherein the forward and aft sides are parallel.

14 . The routing plate according to claim 12 , wherein the body comprises:
a first portion corresponding in location to a portion of the aft side to which the first hydraulic component is affixable; a second portion corresponding in location to a portion of the aft side to which the second hydraulic component is affixable; and a third portion interposed between the first and second portions.

15 . The routing plate according to claim 14 , wherein the first portion has a partially rectangular shape, the second portion has a partially rounded shape and the third portion is tapered from the first to the second portion.

16 . The routing plate according to claim 14 , wherein the interfacial pathways comprise a lube oil supply pathway running from the gearbox, through the first portion of the routing plate and into the first hydraulic component.

17 . The routing plate according to claim 14 , wherein the interfacial pathways comprise a pump drive interface running from the gearbox, through the first portion of the routing plate and into the first hydraulic component.

18 . The routing plate according to claim 14 , wherein the interfacial pathways comprise hydraulic pathways running from the second component, through the second, third and first portions of the routing plate and into the first component.

19 . The routing plate according to claim 14 , wherein the interfacial pathways comprise:
a lube oil supply pathway running from the gearbox, through the first portion of the routing plate and into the first hydraulic component; a pump drive interface running from the gearbox, through the first portion of the routing plate and into the first hydraulic component; and hydraulic pathways running from the second component, through the second, third and first portions of the routing plate and into the first component.

20 . The routing plate according to claim 12 , further comprising a transfer tube disposed along one of the interfacial pathways for first and second hydraulic component communication, the transfer tube comprising:
a first portion sealably disposable in the routing plate; and a second portion sealably disposable in the first or second hydraulic component.
