An electric module of a fan includes a fan provided with blades which are rotatably movable inside a casing, and an electric machine having a rotor secured to the fan and a stator integrated into said casing. The rotor of the electric machine is integrated into the fan and includes a removable ring which captures axially and transversely from the radially outer ends the blades of the fan and which is received inside said stator which is integrated into the casing.

An assembly for an aircraft propulsion system includes a variable area inlet with a fixed structure and a moveable structure. The variable area inlet is configured to open and close an airflow inlet passage into the aircraft propulsion system. The moveable structure is configured to move axially along a centerline between an aft position and a forward position. The moveable structure includes an inlet lip structure and a deflector. When the moveable structure is in the aft position, the airflow inlet passage is closed, and the deflector is at least partially recessed into the fixed structure. When the moveable structure is in the forward position, the airflow inlet passage is opened axially between an aft end of the inlet lip structure and a forward end of the fixed structure, and a forward end of the deflector is disposed axially at the forward end of the fixed structure.

An assembly includes a variable area inlet and an inlet duct. The variable area inlet includes an inlet structure and a center body structure. The inlet structure extends circumferentially about the center body structure with an outer inlet passage radially between the center body structure and the inlet structure. The center body structure includes an outer body and an inner body. The outer body extends circumferentially about the inner body with an inner inlet passage radially between the inner and outer bodies. The inner body is configured to move along a centerline relative to the outer body between a first position and a second position. The inlet duct is fluidly coupled with the outer inlet passage when the inner body is in the first position. The inlet duct is fluidly coupled with the outer inlet passage and the inner inlet passage when the inner body is in the second position.

A valve assembly for an anti-ice system of an aircraft. The valve assembly comprises: a valve body; a first piston; and a regulating piston. The valve body defines a valve inlet, a valve outlet, a fluid passage between the valve inlet and the valve outlet, and a core portion defining a first chamber by cooperation with the first piston and a regulating chamber by cooperation with the regulating piston. The first piston is moveable between a first position and a second position, and the regulating piston is movable between a first position and a second position. The first piston overlaps the regulating piston when the first piston is its first position and the regulating piston is in its second position.

A blower assembly for providing air to an airframe system, including a rotor configured to be mechanically coupled to a spool of a gas turbine engine and a flow modifier configured to receive and/or direct flow to the rotor; wherein the blower assembly is configured to permit relative movement between the rotor and the flow modifier to move between: a compressor configuration in which the rotor is configured to be driven to rotate by the spool and to receive and compress air from the gas turbine engine, and discharge the compressed air for supply to the airframe system; and a turbine configuration in which the rotor is configured to receive air from an external air source to drive the spool to rotate.

A rotor for use in an aircraft engine, that has been repaired by (a) welding together a first portion of a damaged blade of the rotor and a second portion of metal to form a weld nugget, (b) compressively stressing the weld nugget throughout its volume, and (c) heat treating the compressively stressed weld nugget to recrystallize metal therein.

An assembly of at least two members. One of the members supports the other member, the assembly defining an axial direction, a radial direction, and a circumferential direction, an inner member of the at least two members being received radially inside an outer member of the at least two members, wherein the inner member and the outer member am attached to each other by a support arrangement, the support arrangement including at least one floating support assembly as a displaceable coupling between an inner member support point provided at the inner member and an outer member support point provided at the outer member. A displacement of support points in a radial direction results in an interrelated relative displacement of the support points in an axial direction end vice versa.

An engine pod for a gas turbine engine which includes a pod wall having an inside and an outside. The pod wall includes a fixed downstream portion and a displaceable upstream portion which is displaceable in the axial direction between a first upstream position and a second downstream position. At its downstream end facing the fixed portion, the upstream portion forms a radially outer rear edge and axially spaced therefrom a radially inner rear edge, with a recess in between. It is provided that adjacent to the recess, an air-permeable structure is formed in the upstream portion which is intended and configured, in the first upstream position of the displaceable portion, to conduct air flowing in the region of the recess to the inside of the displaceable portion. According to a further aspect of the invention, the axial position of the radially inner rear edge varies in the circumferential direction.
