A forming system includes a femtosecond laser and a control unit that includes one or more processors operatively connected to the femtosecond laser. The femtosecond laser is configured to emit laser pulses onto an inner surface of a face sheet of an acoustic inner barrel. The acoustic inner barrel includes an acoustic core comprising an array of hexagonal cells attached to an outer surface of the face sheet that is opposite the inner surface. The control unit is configured to control the femtosecond laser to laser drill a plurality of perforations in the face sheet via emitting laser pulses at pulse durations between about 100 femtoseconds and about 10,000 femtoseconds and at frequencies over 100,000 Hz.

Through_holes having a high contour accuracy are produced by the multiple use of a nanosecond laser without that the interface between the ceramic layer and the substrate is damaged.

A rotor is provided, in particular a blisk of a gas turbine, including a rotor disk or a rotor ring and rotor blades disposed on a periphery of the rotor disk or rotor ring. At least one radial slot is provided in a peripheral surface of the rotor disk or rotor ring between two rotor blades, which radial slot opens into a rounded opening extending between axial end faces of the rotor disk or rotor ring. A method for manufacturing the rotor is also provided.

The invention relates to a turbomachine blade comprising a vane. The vane comprises a leading edge, a trailing edge, a pressure face and a suction face spaced apart from each other and connecting the leading edge to the trailing edge. The vane further comprises at least one internal cavity between the pressure face and the suction face, wherein air is intended to flow. The vane comprises intersecting transverse partitions, downstream of the cavity, so that air can flow from the cavity in the direction of the trailing edge between the intersecting partitions.

A disc for use in a turbine rotor is provided including a hub, a plurality of webs extending outwardly from the hub, and a plurality of rims. Each of the plurality of webs are separate from each other by a gap. Each rim is positioned at an outward end of one of the webs. Each rim is configured to receive a respective set of turbine blade.

A gas turbine engine component that includes a structure having a surface which includes multiple cooling channels having a width of 20-30 m and a depth of 25-50 m.

A casing that is for a rotating machine and that is configured such that a plurality of housings are linked together, the casing comprising: a first housing including a first connection part that protrudes outward in a radial direction of the rotating machine and that has a first surface extending along the radial direction; a second housing including a second connection part that protrude outward in the radial direction and that has a second surface extending along the radial direction and being in contact with the first surface; and at least one fastening device that fastens the first connection part and the second connection part in the axial direction of the rotating machine, wherein at least one of the first surface or the second surface includes, at least at a portion thereof, a rough surface region having formed therein a plurality of laser irradiation marks formed by irradiation with laser light.

A method of correcting a manufactured article includes applying a machinable coating to a manufactured ceramic matrix composite article with a manufacturing artifact and machining the machinable coating to provide a desired geometry. A method of correcting a manufactured article and a corrected article are also disclosed.

Methods and systems for treating components are described. The methods include using a system having a controller, a laser applicator, a coating applicator, and a sensor array. The laser applicator, the coating applicator, and the sensor array are arranged on a treatment arm that is controlled by the controller. The method includes scanning a surface to be treated of the component using the sensor array, cleaning the surface to be treated using the laser applicator, defining surface texture patterns, applying laser texturing, and applying a new coating to the surface to be treated using the coating applicator.

A method of making a light weight component is provided. The method including the steps of: forming a metallic foam core into a desired configuration; applying an external metallic shell to an exterior surface of the metallic foam core after it has been formed into the desired configuration; and attenuating the component to a desired frequency by forming a plurality of openings in the external metallic shell.
