Abstract: The disclosure concerns a heat exchange system or cooling system for a flow machine (10) having a cooling duct (30) with a coolant inlet opening (32) and a closure (34) for selectively opening the inlet opening (32). A component (38) is arranged to be fluid washed by flow along the cooling duct (30). A flow injector (40) is spaced from the closure (34) along the cooling duct (30) and oriented to inject flow into the cooling duct (30) in a direction that creates a negative fluid pressure downstream of the closure (34), wherein the closure (34) is openable in response to said negative pressure. The component may be a heat exchanger (38). The flow injector (40) may be fed by a compressor (14, 15) of the flow machine (10).

Abstract: A bleed valve arrangement for a gas turbine engine comprises a bleed valve housing defining a bleed duct through which a bleed flow may pass in use and a valve within the bleed duct operable between a closed position and an open position. The valve position is continuously variable between the closed position and the open position. The arrangement further comprises an ejection duct downstream of the bleed duct. The arrangement is characterised in that the ejection duct has a greater cross-sectional area than the bleed duct immediately downstream of the bleed duct so that the bleed flow experiences a sudden expansion on passing from the bleed duct into the ejection duct.

Abstract: 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.

Abstract: 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

Abstract: 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.
