摘要： A method of welding comprises forming an alternating current electric arc between an electrode (32) of a tungsten inert gas welding torch (30) and a metallic substrate (10). The alternating current has a square wave form which is self supporting and does not require intercycle high frequency support. The square wave alternating current has a wave bias ratio equal to or greater than 90 % forward current to 10 % reverse current. A metal welding rod (38) is supplied into the electric arc for depositing a weld deposit (40) on the metallic substrate (10). The welding method is used to apply a metallic wear resistant coating (40) to an edge surface (20 or 22) on a shroud (18) of a turbine blade (10) and is used to seal a cooling passage of a turbine blade or turbine vane.

摘要： A silicon-enriched aluminide coating for a superalloy article has a composite microstructure including a plurality of bands of silicon rich phases (S1, S2, S3) and a plurality of bands of aluminum rich phases (A1, A2, A3), these bands being spaced apart through the thickness of the coating. The composite microstructure is created by depositing a slurry containing both silicon and aluminum in elemental or pre-alloyed form on the article and heating the coated article above the melting temperature of aluminum to cure the coating, the depositing and curing steps being repeated at least once before diffusion heat treating the resulting layers. Thereupon, all the above process steps are repeated at least once.

摘要： A method of manufacturing a composite material which comprises ceramic fibres in a matrix of a ceramic material. A woven matt of ceramic fibres having an electrically conductive coating thereon is immersed in a sol comprising surface charged ceramic particles. A potential difference is then applied between the fibres and a further electrode placed in the sol. The applied potential difference is continued until the matt has been fully permeated by the ceramic particles. The matt is then removed from the sol and subsequently heated to provide sintering of the permeating ceramic particles.

摘要： Fuel flow is scheduled to a plurality of combustion stages by putting a plurality of engine fuel flow governors in parallel with each other and letting the governor which outputs the lowest fuel demand signal be the one which schedules the total fuel flow to the engine. Fuel flows to the plurality of combustion stages are then individually scheduled to achieve the lowest fuel flows consistent with predefined temperature limits for the corresponding stages of combustion.

摘要： A method of and apparatus for the removal and replacement of part of a gas turbine engine powerplant (10). Two beams (25) are attached to the pylon (13) from which the powerplant (10) is suspended from an aircraft. Those parts of the powerplant (10) which are not required to be moved are suspended from carriages (28, 29) which are translatable along the beams (25) when the parts which are to be removed are disconnected from the remainder of the power plant (10). The carriages (28, 29) together with the parts which they carry are then translated to a position which permits the removal of the remaining parts. Replacement of the removed part is essentially the reverse of the procedures for parts removed. The method reduces the time taken to replace powerplant parts.

摘要： A fibre reinforced component (20) such as an aerofoil blade comprises a plurality of layers of fibres (22, 23, 24) impregnated with a matrix material. Each layer (22, 23, 24) is constituted by a fabric which has been initially woven in the form of a tube. At least one of the fabric tubes is deformed after weaving so as to alter the configuration of its fibres.
