The present invention relates to methods and devices for post mould processing of a composite structure, wherein the composite structure extends along a longitudinal direction and comprising a main composite part, and a flange section extending around a perimeter of the main composite part. The flange section comprises an upper surface having a first mating part with a specific shape in a cross-sectional plane perpendicular to the longitudinal direction, the first mating part being located at a fixed position relative to the main composite part. The method may comprise attaching a guiding device to the outer surface of the composite structure and inspecting and/or processing the surface area with a tool fitted to the guiding device.

A method for building structures on existing components includes preparing an auxiliary plate suitable for fastening on the working plate, wherein the auxiliary plate has at least one reference marking, fastening the component on the auxiliary plate, optionally processing the at least one surface to be processed for providing a surface that is substantially parallel to the working plane of the device, measuring the at least one reference marking and the component, wherein the position is recorded, introducing the auxiliary plate with the at least one reference marking and the component into the device and detachably fastening the auxiliary plate on the working plate and processing the component in the device for additive manufacturing by working data on the basis of measuring data. A device and a composite structure for additive manufacturing is used in the method.

A fixture for drilling a hole in a superalloy turbine blade includes a mount to selectively hold a root of the superalloy turbine blade with the superalloy turbine blade extending from the mount. The fixture may also include an actuator to apply a force to elastically deform at least a portion of the superalloy turbine blade when held by the mount from a relaxed, initial position to an elastically deformed position, the at least a portion of the superalloy turbine blade having a curvature in the elastically deformed position not present in the relaxed, initial position. The fixture may also include a drill guide configured to guide a drilling element into the superalloy turbine blade in the elastically deformed position.

A bond fixture including a plurality of supports mounted about a surface. At least one of the plurality of supports includes a vertical member and a hand crank operable to adjust a position of the vertical member. A first fixture is disposed at an end of the bond fixture and is movable relative to the surface. The first fixture includes a base and a support extending from the base. A second fixture includes a first member and a second member movably coupled. A fastener extending between the first member and the second member controls relative movement of the first member and the second member to define an opening there between. Each of the first member and the second member includes a plate having a heater formed therein.

A method machines or tests a blade for a turbomachine. The method includes: clamping the blade in a clamp such that a point contact or a line contact forms between the blade and the clamp as clamping partners. One of the clamping partners has a lower strength than the other clamping partner and plasticizes in the region of the point contact or the line contact.

A directional translating clamping device comprises a housing that includes a distal housing end and proximate housing end separated along a central axis, and a housing recess at the proximate housing end and extending along the central axis end. The device also includes a slide located in the housing recess, and the slide comprises a slide recess at a slide proximate end co-axial with the housing recess, and a detent in a radial sidewall of the slide prevents the slide from translating beyond a predetermined axial distance along the central axis. A spring is located in the housing recess and exerts an axial force on the distal end of the slide. A stub shaft extends from the distal end of the housing. A roller ball assembly includes a threaded sidewall that engages with the slide recess to removably and replaceably secure the roller ball assembly to the slide.

A fixture for repairing a fan blade may comprise a base having a first side, a second side, a tip end, and a foot end, a first support coupled at the first side and perpendicular to the base, a second support coupled at the second side and perpendicular to the base, and a footboard, perpendicular to the base coupled orthogonally between the first support and the second support at the foot end of the base, wherein the footboard comprises a chuck adapted to receive the foot of a fan blade.

A universal jig is provided for clamping wind turbine blades. The jig has a rectangle-like shape forming a space for clamping a blade at the blade root or the blade body. The jig comprises a set of vertically-moving parts; a set of horizontally-moving parts; a plurality of adjusted pads; and a plurality of positioning parts. The vertically-moving parts comprise two upper connecting posts and two lower connecting posts sheathed with each other separately to form two length sides of the jig. The horizontally-moving parts comprise two left connecting posts and two right connecting posts. The adjusted pads are locked on the left and the right connecting posts. The positioning parts are locked at the upper and the lower connecting posts of the length sides of the jig and are locked at the left and the right connecting posts of the width sides of the jig.

A bond fixture including a plurality of supports mounted about a surface. At least one of the plurality of supports includes a vertical member and a hand crank operable to adjust a position of the vertical member. A first fixture is disposed at an end of the bond fixture and is movable relative to the surface. The first fixture includes a base and a support extending from the base. A second fixture includes a first member and a second member movably coupled. A fastener extending between the first member and the second member controls relative movement of the first member and the second member to define an opening there between. Each of the first member and the second member includes a plate having a heater formed therein.

A system includes a stand having a first axis, a first arm, and a second arm. The first arm and the second arm extend from the axis. The first arm is configured to rotate about the axis and the second arm is configured to rotate about the axis. The system includes a first can coupled to the first arm. The first can is configured to be disposed around a first tip of a first airfoil, the first can is configured to receive a first gas flow, and the first can is configured to distribute the first gas flow to a first work cavity around the first tip of the first airfoil. The system further includes a second can coupled to the second arm. The second can is configured to be disposed around a second tip of a second airfoil, the second can is configured to receive a second gas flow, and the second can is configured to distribute the second gas flow to a second work cavity of the second airfoil.
