Abstract:
A combustor swirler for a gas turbine engine and method of manufacturing by injection moulding an inner component and an outer cylindrical component. Indentations are moulded in of the inner and outer component and sealed by the engagement of the components together to form a series of fluid flow passages.
Abstract:
A heat shield comprises a flexible inner jacket configured and disposed to be fitted around at least a portion of a component, and a flexible outer jacket configured and disposed to be fitted around the inner jacket.
Abstract:
The positioning arrangement comprises at least one pair of complimentary rounded recesses, each recess being provided on the mating face of the corresponding component. One ball is positioned between each pair of complementary recesses.
Abstract:
A modular fuel nozzle configuration is defined which permits lower-cost manufacturing operations such as injection moulding to be employed. Also described is a method of making such a component.
Abstract:
A method of manufacturing a composite wall with an open cell metal foam core layer bonded to an inner cladding layer and an outer cladding layer. The method involves: creating a core substrate of open cell gas permeable foam in a chosen shape; impregnating the open cell foam substrate with metal vapour and depositing a porous layer of metal on exposed internal and external surfaces of the substrate thereby forming the open cell metal foam core through metal vapour deposition; and forming the inner and outer cladding layers upon the metal foam core through spray application of metal or ceramic.
Abstract:
A modular fuel nozzle configuration is defined which permits lower-cost manufacturing operations such as injection moulding to be employed. Also described is a method of making such a component.
Abstract:
A fuel supply assembly for a gas turbine engine including a manifold portion with a transfer conduit, a fuel nozzle with an entry conduit and disconnectable means for retaining the transfer and entry conduits in mating engagement with one another.
Abstract:
A method of distributing fuel in a fuel nozzle comprises: providing at least two helical channels in the fuel nozzle, each having a channel exit port, providing a fuel inlet cavity in fluid communication with the helical channels, and flowing fuel in the fuel inlet cavity, the helical channels and the channel exit ports.
Abstract:
A spray device, useful for example as a fuel nozzle for gas turbine engines, comprises a body having a bore and a cap member having an orifice, the body and cap member in combination defining a chamber. Fluid passages introduce pressurized liquid into the chamber and direct a flow into the bore, thereby causing a spinning flow to be forced out through the orifice.
Abstract:
A fuel conveying member for an engine, the fuel conveying member having heating means integrated therein to permit pyrolysis of carbonaceous deposits.
