A raft assembly (700) for a gas turbine engine is provided. The raft assembly comprises a rigid raft (702) formed of a rigid material that has an electrical system and/or a fluid system embedded therein. The raft assembly further comprises one or more clamps for mounting tubular members (704) to the raft. The or each clamp has a first clamp block (706) and a second clamp block (708) 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 (750) 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

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.
摘要:
A method for providing tension to a data or power transmission line in a pipe includes inserting a transmission line into a transmission line channel of a pipe. The transmission line has a first end and a second end and is inserted into a first end of the pipe second-end-first and has a first tension-load-supporting mechanism attached to the first end of the transmission line. The method includes applying a first level of tension to the transmission line in the pipe and applying a second tension-load-supporting mechanism to the second end of the transmission line while the first level of tension is applied to the transmission line. The method further includes removing the first level of tension from the transmission line to maintain a second level of tension along the transmission line between the first and second tension-load-supporting mechanisms.
摘要:
The present invention relates to a conductive link and method of use in constructing a security system. The link includes a substantially flat elongate body aligned substantially within a first plane. At least one tab extends from each end of the body, each tab having an attachment portion configured to connect an end of the conductive link directly or indirectly to an electric fence strainer. The tabs and attachment portions are positioned substantially within a second plane oriented to be substantially non parallel to the first plane.

An electrical wiring assembly for a gas turbine engine is provided. The wiring assembly (600, 200) comprises a rigid electrical assembly formed of a rigid material that includes an electrical system comprising electrical conductors (252) embedded in the rigid material (220). The wiring assembly further comprises an engine component that is mounted to the electrical assembly . The electrical assembly includes one or more integral cooling passages (210, 285) which guide a coolant fluid through the assembly to cool the engine component

An anti-vibration mount is provided for mounting a first component to a second component. The mount has an elastomeric body (714) which provides a recess into which the first component (710) is received. The mount further has pair of brackets (722) which fit to opposing sides of the elastomeric body sandwiching the first component received in the recess therebetween. At least one of the brackets (726) is arranged to connect the anti-vibration mount and second component (700) together. The mount further has a clamping arrangement (724) which applies clamping pressure across the brackets (722)and thereby compresses the elastomeric body (714) to secure the first component (710) in the recess.
摘要:
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.
