Abstract: A facility for assembling aircraft fuselages comprises a plurality of movable cradles. Each cradle is configured to support a fuselage keel structure and assemble a panelized fuselage from the keel structure to obtain a full fuselage contour in a single upright build position.

Abstract: The invention relates to a device for setting fastening elements, wherein a master shaft rod can be moved via a master motion link into a forward set position in order to be able to set the fastening element also at inaccessible or vertical locations.

Abstract: The invention pertains to an applicator (1) for inserting an implant, in particular a rod-like implant (2) containing an active substance, under the skin of a human or animal, comprising a housing (3), a cannula (6) extending from the housing (3), and a handle (15) for grasping and maneuvering the applicator (1) and the cannula (6) during insertion of an implant (2). In accordance with the invention, the handle (15) extends above at least part of the length of the cannula (6). Such a handle facilitates insertion of the cannula and/or accurate positioning of the implant.

Abstract: Disclosed is a method for producing a fuselage of an aircraft, wherein several fuselage sections that are arranged one behind another are joined together, comprises the following steps: a) production of an outer skin segment, the outer skin segment having on the underside a continuous longitudinal opening, b) widening the outer skin segment in order to introduce at least one floor frame, c) joining the outer skin segments to a rigid fuselage section which is already present, with the formation of a partial transverse seam, d) positioning a prefabricated lower shell in the longitudinal opening, in order to close the outer skin segment on the peripheral side, e) completing the partial transverse seam to form a transverse seam and joining the lower shell together with the outer skin segment with the formation of at least two longitudinal seams, and f) joining the floor frame together with the outer skin segment.

Abstract: Embodiments of the present invention pertain to a drop hammer comprising a load, an actuator connected to the load, and a fluid circuit that is connected to the actuator and is connectable to a fluid source, such as a source of hydraulic power. The fluid circuit is operable with differential pressure to displace the load. The fluid circuit includes a slow-release device for releasing differential pressure, thereby slowly displacing the load as a function of flow from the fluid source. Embodiments of the present invention also pertain to a drop hammer comprising a frame, a selectively actuated rotatable sprocket mounted on the frame, a hammer implement, and at least one chain engaged by the sprocket. The chain includes two-pitch link that includes a catch between two pitched wings, the catch being configured for engaging the hammer implement, enabling the first chain to displace the hammer implement.

Abstract: A taper implant of the invention comprises a taper portion having an outer surface being frustconical in shape, a flange portion formed at an outermost end of the taper portion on the larger-diameter side to project outward with respect to the taper portion and having a flat surface lying perpendicularly to the axial direction of the taper portion, and female threads serving as a fit portion extending in the axial direction of said taper portion. A hole taper portion and a hole step portion are drilled at the same time to bore a hole in one of members to be fastened, and the taper implant is driven into the hole, thereby providing a screw-fastening structure for the fastened members. The taper implant ensuring good working efficiency is achieved.

Abstract: The present invention provides a fastening assembly system for applying fasteners along the seams of a cylindrical structure. The fastening apparatus includes a base unit which releasably attaches to a cylindrical structure, and a first fastening device coupled the base unit for applying fasteners along a seam of the cylindrical structure. The base unit may be embodied as either two crescent shaped members in parallel alignment for attaching to the upper half of the cylindrical structure. Alternatively, the base unit may include a base plate that is attachable to the floor beams on the interior of the cylindrical structure. In the preferred embodiment, the first fastening device cooperate with a second fastening device located on the opposite side of the cylindrical structure during the fastening process.

Abstract: The present invention relates to a portable process for automated fastening of aircraft structures. The invention will employ two primary elements for locating and installing through-the-skin fasteners. Inside and outside units are attached onto an airframe and indexed to each other through coordination holes that have been pre-drilled through the structure. The aircraft structure is assembled with the pre-drilled coordination holes by aligning adjacent airframe parts and inserting alignment pins. The alignment pins will provide a degree of clamping to pull the parts together and provide indexing for inside and outside vacuum attachment track systems. The invention is equipped to traverse along the track system, accurately position itself, and drill only or countersink a hole, insert a fastener, and fasten, i.e., upset a rivet, or run down a threaded nut, then reposition itself to the next fastener location and repeat the process.

Abstract: A machine comprising a horizontally elongated base having pairs of pylons slidably mounted on opposite sides of the base for horizontal movement along the length thereof, forming in effect, a moveable C-frame. The workpiece is fixedly supported on the base in a substantially vertical position, and the pylons of each pair work together on opposite sides of the workpiece to process rivets/fasteners or perform other functions. Each of the pylons comprises a vertical first component and a horizontal second component. The second component is movable vertically on the first component, and is also movable horizontally toward and away from the workpiece. Carried on the end of each of the horizontal second components adjacent the workpiece is a tool assembly holder that is rotatable about horizontal and vertical axes.

Abstract: A system for setting or driving wedge sockets into holes of a structural ponent combines a mounting member having two shaft sections forming the socket, with a driver having a pistol shape with a pistol grip and a trigger for releasing an automatic impact force. The driver, for example energized by compressed air or by a cocked spring, applies a predetermined impact energy to one of the two shaft sections. The apparatus enables an operator to work efficiently, especially where large numbers of such fasteners must be set.

Abstract: An apparatus for supplying a blind rivet to a riveting device includes a rivet supplying conduit through which the rivet is supplied, a guide member to which a nose of the riveting device is moved from the workpiece, a rivet holder element for receiving the rivet, and a piston-cylinder unit for transporting the rivet holder element. The piston-cylinder unit operates to transport the rivet holder element from a position in which the rivet from the supplying conduit is received in the holder element to a position in which the nose of the riveting device approaches the holder element and holds a mandrel of the rivet.
