There is disclosed an axial flow machine () comprising an annular flow path (); a stator ring () comprising a plurality of stators mounted at their radially outer ends and extending into the annular flow path (); a non-rotating body () axially adjacent the stator ring (); and an annular shroud () disposed between the radially inner end of the stator ring () and the body (). The shroud () is supported on the stator ring () and moveable relative the body (); and the shroud () cooperates with the body () to inhibit a flow through a clearance pathway () therebetween.

Axial flow machine

An aerofoil assembly including an aerofoil and a spray element that supplies fluid to a gas turbine engine. The aerofoil has a first part with a leading edge when located in the gas turbine engine, and a second part with a trailing edge when located in the gas turbine engine. The first part has features that slide relative to and engage with complementary features of the second part to form a releasable arrangement.

Components for a gas turbine engine

In order to allow dual fuel operation, that is to say gas and liquid fuel, a fuel injection arrangement and an assembly are provided in which an injection conduit provides constriction to an airflow towards an outlet. In an assembly a plurality of arrangements including liquid fuel jets are arranged to such that through high angle incidents by the airflow appropriate vaporization and droplet formation is achieved for a fuel/air mixture combustible in a combustor of a turbine engine. At low liquid fuel flow rates below a pre-determined level the liquid fuel is atomised and entrained by the airflow. At high liquid fuel flow rates the fuel splash impinges upon a wash surface to develop a wash film which is again vaporised and atomised about an edge for a fuel/air mixture capable of combustion.

Fuel injection

A joint for a gas turbine fuel injector, the joint comprises a housing for supporting a fuel injector, a first tube terminating within the housing and a second tube. The housing at least partially encloses an adaptor having a bore, with one end of the first tube and one end of the second tube being located within opposing ends of the bore. First sealing means are provided between the outside of the first tube and the adaptor bore, second sealing means are provided between the outside of the second tube and the adaptor bore and third sealing means are provided between the outside of the adaptor and the housing. The joint is particularly suitable for conduits carrying a relatively cold fluid mounted in a relatively hot housing.
