Patent number: 9934885Abstract: A gas turbine engine 10 is provided with electrical harness rafts 200 comprising electrical conductors embedded in a rigid composite material. The rafts 200 are used to transport electrical signals (which may be, for example power and/or control signals) around a gas turbine engine. Rafts 200 may be connected together and to other components using flexible cables, that may help to accommodate relative movement of the rafts 200, for example through vibration. The rafts 200 are lighter, more compact, and more convenient to handle than conventional electrical harnesses. The rafts 200 may provide a convenient and secure mounting surface for other components/systems of a gas turbine engine, such as EECs and/or fluid pipes.Type: GrantFiled: December 17, 2012Date of Patent: April 3, 2018Assignee: ROLLS-ROYCE plcInventors: Paul Broughton, Robin Charles Kennea

Patent number: 9730275Abstract: A gas turbine engine 10 comprises at least one rigid raft assembly that has a fluid passageway 210 at least partially embedded therein. The fluid passageway 210 is at least a part of a fluid system. In addition to the fluid passageway 210, the rigid raft assembly 200 also has at least a part of another system. For example, the rigid raft assembly may also include electrical conductors 252, which are part of an electrical system. The rigid raft assembly 200 may be lighter, easier to assemble, more robust and more compact than conventional solutions for providing systems to gas turbine engines.Type: GrantFiled: December 17, 2012Date of Patent: August 8, 2017Assignee: ROLLS-ROYCE plcInventors: Paul Broughton, Richard Peace, Gary Alan Skinner, Robin Charles Kennea

Patent number: 9730274Abstract: An electrical raft 200 comprising electrical conductors 252 embedded in a rigid material are provided to a gas turbine engine. The raft 200 is used to transport electrical signals (which may be, for example power and/or control signals) around a gas turbine engine. The electrical raft 200 has an electrical connector 700 embedded therein which is used to connect the electrical raft to an electrical unit, such as an EEC of a gas turbine engine The electrical connector 700 is resiliently biased so as to ensure a reliable electrical connection.Type: GrantFiled: December 17, 2012Date of Patent: August 8, 2017Assignee: ROLLS-ROYCE plcInventors: Paul Broughton, Richard Peace, Gary Alan Skinner, Michael Christopher Willmot, Robin Charles Kennea

Patent number: 9713202Abstract: The present invention provides a gas turbine engine part which has a primary purpose in the engine which is structural and/or aerodynamic. The part is formed of rigid composite material, and has an electrical system comprising electrical conductors permanently embedded in the composite material. This provides advantages in terms of weight, complexity, and build time.Type: GrantFiled: December 17, 2012Date of Patent: July 18, 2017Assignee: ROLLS-ROYCE plcInventors: Paul Broughton, Richard Peace, Gary Alan Skinner, Robin Charles Kennea

Patent number: 9699833Abstract: An electrical assembly 600 comprising an electrical raft 200 and an electronic unit 300 is provided to a gas turbine engine 10. The electrical raft 200 has electrical conductors 252 embedded in a rigid material 220, which may be a rigid composite material. The electrical conductors 252 are in electrical contact with the electronic unit 300. When the electronic unit 300 is installed, at least a part 310 of it forms a part of a gas-washed surface of the engine 10. The electronic unit 300 is then easily accessible from the engine 10, and potentially complex and/or heavy access doors/panels may not be required.Type: GrantFiled: December 17, 2012Date of Patent: July 4, 2017Assignee: ROLLS-ROYCE plcInventors: Paul Broughton, Richard Peace, Gary Alan Skinner, Robin Charles Kennea

Patent number: 9426843Abstract: An electrical raft (200) is provided that has electrical conductors (252) embedded in a rigid material (220). The electrical raft is provided with an electrical connector (700). The electrical connector (700) is mounted in the electrical raft (200) at a mounting angle (730). The mounting angle is set such that the electrical conductors (252) can be connected to the electrical connector without having to turn through an angle or a radius of curvature that would subject them to excessive bending stress. Similarly, the mounting angle means that any conductors (766) that may be connected to the electrical connector (700) do not have to turn through an angle or a radius of curvature that would subject them to excessive bending stress. Furthermore, mounting the electrical connector (700) at the mounting angle (730) may allow the assembled electrical raft (200) to be more compact.Type: GrantFiled: December 17, 2012Date of Patent: August 23, 2016Assignee: ROLLS-ROYCE plcInventors: Michael Christopher Willmot, Matthew Peter Fitt, Philip Summerfield, Paul Broughton, Richard Peace, Gary Alan Skinner, Robin Charles Kennea

Patent number: 9426844Abstract: An electrical raft 200 is provided that has electrical conductors 252 embedded in a rigid material 220. The electrical raft 200 may have other embedded components, such as embedded fluid pipes 210. The electrical raft 200 is provided with a raft map 400 that indicates the location and/or path of components embedded in the electrical raft 200. The raft map 400 can be used to identify the positions of the embedded components, and may also be provided with active elements, such as LEDs, which may be used to indicate an operating state of the systems/components embedded in the electrical raft 200. The raft map 400 may be useful in assembly, repair and fault diagnosis, for example.Type: GrantFiled: December 17, 2012Date of Patent: August 23, 2016Assignee: ROLLS-ROYCE PLCInventors: Paul Broughton, Richard Peace, Gary Alan Skinner, Robin Charles Kennea, Michael Christopher Willmot, Philip Summerfield

Patent number: 9338830Abstract: A raft assembly for a gas turbine engine is provided. The raft assembly includes a rigid raft formed of a rigid material that has an electrical system and/or a fluid system embedded therein. The raft assembly further includes one or more clamps for mounting tubular members to the raft. The or each clamp has a first clamp block and a second clamp block which, in use, clamp together to grip a tubular member between the blocks. The first block is fixed to the raft. The or each clamp further has a fastener operatively extending between the blocks. The fastener is tightenable to apply a clamping load between the blocks, and releasable to remove the clamping load such that the second block can be moved relative to the first block to allow the tubular member to be received between or removed from between the blocks.Type: GrantFiled: December 17, 2012Date of Patent: May 10, 2016Assignee: ROLLS-ROYCE plcInventors: Paul Broughton, Richard Peace, Gary Alan Skinner, Robin Charles Kennea
