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.
Claims16
A gas turbine engine comprising:
- a nacelle;
- and
- an electrical assembly that comprises:
- an electrical raft having a rigid material with at least one electrical conductor embedded therein;
- and
- an electronic unit mounted on the electrical raft and in electrical connection with the electrical raft,
- wherein:
- the electrical raft is mechanically fixed to a component of the gas turbine engine;
- and
- at least a part of the electronic unit has an external surface that is flush with an external surface of the nacelle and is exposed to free-stream flow.
A method of attaching an electronic unit to a gas turbine engine, the gas turbine engine comprising a nacelle and an electrical raft,
- the method comprising:
- slotting the electronic unit into an opening formed in a gas-washed surface of the nacelle;
- and
- electrically connecting the electronic unit to the electrical raft, the electrical raft comprising a rigid material with at least one electrical conductor embedded therein;
- wherein
- an external surface of the electronic unit, when inserted into the opening, is flush with an external surface of the nacelle that completes the gas-washed surface in which the opening is formed;
- and
- the external surface of the electronic unit is exposed to free-stream flow.
