A method and apparatus for performing an assembly operation. A tool may be macro-positioned relative to an exterior of a fuselage assembly. The tool may be micro-positioned relative to a particular location on the exterior of the fuselage assembly. An end effector is removably associated with an external robotic device associated with an external mobile platform. The tool is removably associated with the end effector. An assembly operation may be performed at the particular location on the panel using the tool.

A device for transmitting torque on an axis from a drive to an output has a first connection for connecting with the drive and having a vulcanization surface, and a second connection for connecting with the output and also having a vulcanization surface. An elastic element formed of rubber-elastic material is in the power transmission path between the two connections, is constructed so as to be radially soft, permitting a radial offset of up to 1 mm between the first connection and the second connection, is torsionally rigid to permit an only very small torsion angle of at most 1.5 between the first connection and the second connection, and is vulcanized to the vulcanization surface of the first connection and to the vulcanization surface of the second connection.

An engine cylinder head comprising an internal metal structure formed from a metal material and an external polymer composite structure formed from a polymer composite material, wherein the external polymer composite structure at least partially surrounds the internal metal structure.

An engine cylinder head includes an internal metal structure formed from a metal material, at least a portion of which includes a thermal coating and an external polymer composite structure formed from a polymer composite material, wherein the external polymer composite structure at least partially surrounds the internal metal structure.

A gear housing for an epicyclic gear set, the gear housing including a hollow wheel having internal teething and a first front end with a first front-side joining surface; a housing cover having a second front end with a second front-side joining surface for longitudinally axially covering the hollow wheel; and a bonded connection for connecting the first front end to the second front end through the mating of the first and second front-side joining surfaces, at which the hollow wheel and the housing cover are connected to each other by a bonded connection, in particular, by heated tool welding, infrared welding, ultrasonic welding, or rotary friction welding.

A method and apparatus for positioning an end effector relative to a fuselage assembly. A configuration of the fuselage assembly may be determined. The end effector may be positioned relative to the fuselage assembly based on the configuration determined. A set of actual reference locations may be identified for a set of reference points on the fuselage assembly. The end effector may be positioned at an operation location based on the set of actual reference locations identified.

A torque rod is provided to be linked with a vibration-producing portion and a vibration-receiving portion. A fiber-shaped resin is woven between plural arrayed fiber-shaped reinforcing members. The fiber-shaped resin is melted to form a thermoplastic resin layer that is integrated with the reinforcing members. A thermoplastic resin that forms a covering layer is laminated onto a surface of the thermoplastic resin layer.

A method and apparatus for installing a fastener. A reactive structural force is generated in a first direction during installation of the fastener. A new reactive structural force is generated in a second direction opposite to the first direction during the installation of the fastener.

A method of manufacturing a component (100) having a main part (101) and a projecting feature (104,114), the method comprising providing a shaped void (210) corresponding to the component, locating a pre-formed element (214) in a feature region of the shaped void which corresponds to the projecting feature, locating powder (212) within the shaped void; and forming the element and the powder into the component such that the element creates at least a part of the projecting feature.
