摘要： A duct (100) for a gas turbine engine system (not shown) is used to convey exhaust gas and bypass air away from the engine system, towards an exhaust nozzle (28). The duct (100) comprises an inlet face (120) having at least two inlet portions (122) and defines the outer extremity of a path (104) for the gas and/or air through the duct (100). The duct (100) comprises a plurality of flat panel members (140) which together define the outer extremity of the path (104).

摘要： A gas turbine engine casing assembly (200)has a first casing element (210) which is located radially outward of one or more rotating aerofoil elements (170) of the gas turbine engine.
The first casing element (210) is radially enclosed by a track element (220) , a septum layer (130), a second casing element (140) and a fan case (150).
The track element (220) is formed from an abrasion resistant material in order to prevent abrasion of the septum layer (130) during excoriation of the first casing element (210).

摘要： A turbine fuel supply system is disclosed as including a first sub-system having: a first nozzle for injecting fuel into a combustor of a turbine engine; a first valve controllable to communicate fuel to the first nozzle; and a first fuel manifold for communicating fuel to the first valve from a fuel source; the system further including a controller assembly for raising the pressure of fuel in the first fuel manifold; and the system being characterized in that the first valve is adapted to open in response to a predetermined pressure difference between the first fuel manifold and the pressure in the combustor, thereby allowing fuel to be communicated from the first fuel manifold to the first nozzle. The system may include a first recirculating conduit in fluid communication with the first fuel manifold and the fuel source, the first recirculating conduit allowing fuel not communicated by the first valve to be returned to the fuel source.

摘要： The invention relates to a gas discharge tube (30) of a type that may be used for example in gas turbine engine (10) ignition systems. The gas discharge tube (30) has an envelope (42) containing a gas therein and the envelope has a pair of spaced electrodes (38, 40) for application of an electric potential difference across the gas. An electromagnetic radiation source (44), such as a deep UV light source, is arranged to emit photons (50) into the envelope (42) so as to initiate ionisation of the gas, thereby reducing the potential difference required to cause electrical conductance between the electrodes. The electromagnetic radiation source, which may comprise light emitting diodes, may be selectively controlled.

摘要： A ventilation inlet comprising a ventilation pipe to receive flow from a first flow zone and to deliver the flow to a second flow zone; a divider arranged to divide a portion of the ventilation pipe into a static pressure zone and a total pressure zone; and a deflector arranged to direct flow from the total pressure zone at least partially across the static pressure zone to restrict delivery of the flow from the static pressure zone to the second flow zone dependent on the pressure of the flow in the first flow zone.

摘要： The present invention provides a method of optimising engine wash event scheduling. An underlying deterioration gradient and a total deterioration gradient are determined. A number of engine wash events, x, are set. Engine deterioration for x engine wash events is calculated. The washed engine cost of engine deterioration for x engine wash events is calculated. The calculation of engine deterioration is iterated for different x to optimise the number of engine wash events with respect to the cost of engine deterioration. Advantageously the method systematically optimises scheduling of wash events taking into account the underlying deterioration of the engine which cannot be recovered by engine washing and the cost of the engine wash events.

摘要： A cooling medium supply apparatus 10 has a sensing means 120 and a cooling medium pump mechanism 100 which is powered by a gas turbine engine assembly 140. The gas turbine engine assembly 140 is self-contained with a fuel supply 150, an ignition system 170 and a starting system 180. The sensing means 120 monitors the presence of a primary supply of a cooling medium 110, and on detecting a loss of the primary supply, actuates the gas turbine assembly 140 to provide a secondary supply of the cooling medium 110.
