1. A method for washing an aerofoil of a gas turbine engine having a principal and rotational axis using a multi-nozzle dispenser, the aerofoil comprising: a fan blade, a compressor blade or vane, or an outlet guide vane, the aerofoil having a suction surface and a pressure surface, the suction and
1. A method for washing an aerofoil of a gas turbine engine having a principal and rotational axis using a multi-nozzle dispenser, the aerofoil comprising: a fan blade, a compressor blade or vane, or an outlet guide vane, the aerofoil having a suction surface and a pressure surface, the suction and pressure surfaces having a curve between a leading edge and a trailing edge and a twist between a blade tip and a blade root region, the multi-nozzle dispenser comprising:an elongated hollow body defining a fluid gallery within the hollow body, the hollow body having an axis extending a length of the hollow body;a plurality of nozzles located along the length of the hollow body connected to the fluid gallery so that washing fluid can flow through the fluid gallery and then into the nozzles during use; andat least a first nozzle and a second nozzle being angled at different angles about the hollow body axis and being arranged to eject a washing fluid at different angles relative to said rotational axis and, in use, each nozzle ejects said washing fluid onto different parts of the pressure surface or suction surface, wherein the first nozzle is angled such that a washing fluid jet impinges upon the pressure surface or the suction surface at more than 75 degrees to the surface, and the second nozzle is angled such that a washing fluid jet impinges upon the same pressure surface or suction surface as the first nozzle and at more than 75 degrees to the pressure surface or suction surface,wherein the hollow body comprising a plurality of segments, at least two of the segments having at least one nozzle mounted thereon and being rotatably mounted so that the rotatable segments can each be independently rotated and so that the rotatable segments can be rotated to change the angles of the first and second nozzles about the hollow body axis; said method comprising:locating said multi-nozzle dispenser into said gas turbine engine;angling the first nozzle and supplying washing fluid to the first nozzle sothat the washing fluid jet impinges upon the pressure surface or suction surface at more than 75 degrees to the pressure surface or suction surface; andangling the second nozzle and supplying washing fluid to the second nozzle so that the washing fluid jet from the second nozzle is ejected onto a different part of the same pressure surface or suction surface than the washing fluid jet ejected from the first nozzle impinges and at more than 75 degrees to the pressure surface or suction surface. 2. A method according to claim 1, wherein the hollow body is rotatably mounted so that the hollow body can be rotated to adjust the angle of the first and second nozzles and direct the first and second nozzles at different parts of the pressure or suction surface of the aerofoil. 3. A method according to claim 1, wherein the hollow body comprises at least two segments, at least one nozzle being mounted on each segment, at least one of the segments being rotatably mounted so that the rotatable segment can be rotated to change the angle of the first and second nozzles about the hollow body axis. 4. A method according to claim 1, wherein the nozzle comprises an outlet that is substantially elliptical and the method further comprises producing a generally elliptical shaped jet of washing fluid. 5. A method according to claim 1, wherein the nozzle comprises an outlet that is rectangular and the method further comprising producing a high aspect ratio shaped jet of washing liquid. 6. A method according to claim 1, wherein the first nozzle is angled so that the washing fluid jet impinges upon the first part of the surface of the aerofoil between 85 degrees and 90 degrees to the surface of the aerofoil. 7. A method according to claim 1, wherein the first nozzle is angled such that a washing fluid jet impinges upon the surface of the aerofoil at between 85 and 90 degrees to the surface. 8. A method according to claim 1, wherein the dispenser comprises a gallery for supplying washing fluid to the hollow member and then to the first nozzle. 9. A method according to claim 1, wherein the dispenser is arranged to substantially span the radial extent of the aerofoil. 10. A method according to claim 1, wherein the dispenser is arranged to substantially span the diameter of an annular array of aerofoils. 11. A method according to claim 1, wherein a washing system incorporates said multi-nozzle dispenser, and wherein said washing system comprises a control mechanism capable of adjusting the angle of one or more the nozzles, the method further comprising using the control mechanism to adjust the angle of one or more of the nozzles. 12. A method according to claim 11, wherein the washing system comprises a control system for controlling the control mechanism, the method further comprising using the control system to control the control mechanism. 13. A method according to claim 11, wherein the washing system comprises a pump connected via a pipe to a washing fluid reservoir and the multi-nozzle dispenser is connected via a pipe to the pump, the method further comprising pumping washing fluid from the fluid reservoir to supply the washing fluid to the nozzle. 14. A method according to claim 12, wherein the control system selectively switches on or off the washing fluid flow through each nozzle independently. 15. A method according to claim 12, wherein the control system selectively varies the amount of washing fluid ejected by each nozzle. 16. A method according to claim 1, wherein a washing system incorporates said multi-nozzle dispenser, and wherein said washing system comprises a control mechanism capable of adjusting the angle of one or more of the nozzles by rotating the rotatable sections, the method further comprising using the control mechanism to adjust the angle of one or more of the nozzles by rotating the rotatable sections. 17. A method according to claim 16, wherein the washing system comprises a control system for controlling the control mechanism, the method further comprising using the control system to control the control mechanism. 18. A method according to claim 16, wherein the washing system comprises a pump connected via a pipe to a washing fluid reservoir and the hollow member is connected via a pipe to the pump, the method further comprising pumping washing fluid from the fluid reservoir to supply the washing fluid to the hollow member and the nozzle. 19. A method according to claim 16, wherein the control system selectively switches on or off the washing fluid flow through each nozzle independently. 20. A method according to claim 16, wherein the control system selectively varies the amount of washing fluid ejected by each nozzle.
