A blade containment assembly for a gas turbine engine comprises a casing having a first casing member surrounding a set of rotor blades and a second casing member extending axially from the first casing member. The first casing member has an outer annular wall welded to the second casing member at a weld joint disposed in a blade containment zone of the casing and an inner containment ring spaced radially inwardly from the outer annular wall and extending axially from a first location forward of the weld joint to a second location aft of the weld joint.

A casing assembly includes first case with a first case body at least partially disposed in a hot section. The first case body has a first case flange and the first case body adjacent to the first case flange is resiliently deformable. A second case downstream of the first case has a second case body with a second case flange extending radially outwardly to a radially-outer wall defining an outer diameter of the second case flange. The first case flange abuts the radially-outer wall of the second case flange. The second case has struts extending radially from an inner end to an outer end. The leading edge portion at the outer end of each of the struts has an axial position defined along the center axis that is similar to an axial position of the second case flange.

The proposed solution relates, in particular, to an engine component having at least one first loading zone, which is designed for dynamic loads arising at the engine component when the engine component is correctly built into an engine and when the engine is operating, and a second loading zone, which is provided spaced at a distance from the first loading zone on the engine component and likewise is designed for dynamic loads arising at the engine component when the engine component is correctly built into an engine and when the engine is operating.

The proposal is, in particular, that at least one spatially delimited modification zone with introduced internal tensile stress is formed on the engine component, via which zone a crack propagating in the engine component is guided to the and/or within the second loading zone.

A rework press assembly for reworking a dimensionally non-conformant component is provided. The rework press assembly includes a frame, a die coupled to the frame and configured to contact a first portion of the component, and a ram. The ram is coupled to the frame opposite the die with respect to an axis of the rework press assembly and is configured to contact a second portion of the component. The ram and the die define a component cavity therebetween. At least one of the die and the ram has a first length, relative to the axis, in response to the rework press assembly being at a first thermal condition. The at least one of the die and the ram has a second length, relative to the axis, in response to the rework press assembly being at a second thermal condition, and the second length is greater than the first length.

A method for manufacturing a blade, the method includes casting a nickel alloy blade precursor having an airfoil and a root. The airfoil and the root are solution heat treating differently from each other. After the solution heat treating, the root is wrought processed. After the wrought processing, an exterior of the root is machined.

A hybrid vane for a gas turbine engine. The hybrid vane comprises an airfoil having an inner core composed of a fiber-reinforced thermoplastic composite. A longitudinal axis of the hybrid vane extends between a vane root and a vane tip. The hybrid vane further comprises a metallic outer layer at least partially covering the inner core.

A method for forming a QCr0.8 alloy tapered cylindrical ring, including: heating a standard QCr0.8 alloy cylindrical part followed by upsetting and stretching at least twice to obtain a primary blank; heating the primary blank followed by upsetting and chamfering to obtain a secondary blank, where a diameter of a top end is greater than that of a bottom end; subjecting the secondary blank to backward extrusion to form a preform; machining the preform to remove a flash and a bottom residue; subjecting a bottom end of the preform to local bulging to enable a shape and a size thereof to match that of a drive roller in a forming tooling, so as to form a profiled ring blank; and rolling the profiled ring blank by a radial-axial ring rolling machine with the forming tooling to form the tapered cylindrical ring.

A method of forming a gas turbine engine component according to an example of the present disclosure includes, among other things, attaching a cover skin to an airfoil body, the airfoil body and the cover skin cooperating to establish pressure and suction sides of an airfoil, positioning the airfoil between first and second dies of a deforming station, heating the airfoil body to a first predefined temperature threshold between the first and second dies, and moving the first die relative to the second die to hold the airfoil between the first and second dies subsequent to the heating step, and then deforming the airfoil between the first and second dies.

The invention relates to an intermediate case (25) for a twin spool turbomachine for an aircraft, comprising a hub (26), an outer shell (23) and outlet guide vanes (24) installed at their ends on the hub and on the outer shell, and each of at least some of the outlet guide vanes (24) performing a heat exchanger function and comprising a lubricant passage (50a, 50b) designed to be cooled by the fan flow (58) following an outer surface of the outlet guide vane. According to the invention, the case also comprises at least one lubricant duct (55) passing along a circumferential direction of the hub (26) and at least part of which is made from a single casting with the hub, the lubricant duct (55) having at least one lateral opening communicating with the lubricant passage (50a, 50b) of at least one of the vanes (24).

A forging assembly may comprise a first die and a second die configured to translate toward the second die. A first sensor may be coupled to at least one of the first die or the second die. The first sensor may be configured to output a first signal correlating to a first distance between the first die and the second die. Additional sensors may be applied to track die alignment during the forging process.
