Abstract
A gas turbine engine 10 is provided with rigid raft assemblies 290, which may be electrical harness raft assemblies 290 comprising electrical conductors embedded in a rigid composite material. The rigid raft assemblies 290 can be provided with engine dressings, such as pipework and ECUs to produce an electrical raft assembly. In order to assemble or dress the gas turbine engine 10, the rigid raft assemblies can be pre-prepared to incorporate at least a part of at least one gas turbine engine system/component before being installed on the gas turbine engine 10. During maintenance, whole raft assemblies can be removed and replaced with corresponding, pre-prepared assemblies. This can save considerable time during engine build and maintenance.
Claims17
A method of servicing a gas turbine engine, the method comprising:
- removing a first rigid raft assembly from the gas turbine engine, the rigid raft assembly incorporating at least a part of at least one component or system of the gas turbine engine;
- and
- installing a second, pre-prepared, rigid raft assembly onto the gas turbine engine in place of the first raft assembly.
A method of dressing a gas turbine engine comprising:
- preparing a rigid raft:
- assembly for installing on the gas turbine engine, the rigid raft assembly incorporating at least a part of at least one component or system of the gas turbine engine;
- storing the prepared rigid raft assembly in a storage facility;
- and
- when the gas turbine engine requires dressing, installing the prepared rigid raft assembly on the rest of the gas turbine engine, the prepared rigid raft assembly forming at least a part of the engine dressing.
