An assembly system and method for assembling an aircraft wing box or other structure that may define an interior area accessible through at least one access opening are provided. The method includes inserting a robot having an assembly tool mounted thereto into the interior area through the at least one access opening. The assembly tool may be positioned at a fastener location, and may be clamped to the structure. A hole may be made through the structure, and a fastener may be installed in the hole.

Apparatus for installing fasteners in a workpiece is mounted for computer controlled movement over the workpiece surface. The apparatus includes all of the tools, fasteners, drives and controls on-board that are needed to operate autonomously, without external connections. The apparatus may also include an on-board power supply for powering the tools, drives and controls. A supply of fasteners is held in an on-board replaceable cassette. An on-board fastener transferring device transfers individual fasteners from the cassette to the tools.

A fastener delivery and installation system is provided that comprises an end effector mounted on an automated machine and operable to drill a hole through a workpiece and insert a fastener through the hole, and a fastener feed unit operable with the automated machine to deliver the fasteners through the end effector and into the workpiece. Further, a hand-held tool is operable against a second surface of the workpiece and is aligned with the end effector. Once the hand-held tool is positioned properly, a magnetic field is generated and the workpiece is clamped to enable the end effector to drill a hole through the workpiece and insert a fastener therethrough. Additionally, a detector is located on the hand-held tool for generating guidance information to inform an operator where to move the hand-held tool so as to align the hand-held tool with the end effector.

A pressure clamp assembly for clamping a plurality of overlapping members together. The pressure clamp includes a pair of compression members attached to a clamp body and driven together by a power source. The power source includes a fluid pressure cylinder that repeatably produces high clamping forces so as to inhibit the production of inter-laminate burrs during drilling. The compression members each include an elongated compression foot that distributes the clamping pressure over a wide area to allow drilling in a relatively wide range of locations. In addition, each compression foot defines a drill bit assembly guide that facilitates accurate hole drilling through multiple overlapping parts.

An apparatus for installing rivets or other fasteners through a workpiece includes an automated machine disposed on one side of the workpiece and a hand-held tool that is manipulated by a single worker located on the opposite side of the workpiece. The automated machine includes an end effector supporting tools such as a drill and a riveter. The automated machine also includes a guide structure adapted to be releasably affixed to the workpiece, and a carriage that travels along the guide structure and supports the end effector so that the end effector can be positioned in various locations along the surface of the workpiece where fasteners are to be installed. The end effector includes an electromagnetic clamping device, and the hand-held tool includes a magnetic clamping block that is attracted by the clamping device to clamp the workpiece therebetween. The end effector generates a positioning signal and the hand-held tool includes a detector for detecting the positioning signal. The detector is operable to generate guidance information telling the person operating the hand-held tool where to move the hand-held tool so as to align the tool with the end effector of the automated machine. Once the hand-held tool is aligned with the end effector, the electromagnetic clamping device is activated to clamp the workpiece, and then the end effector tools are operated to drill a hole and to install a rivet or other fastener into the hole.

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.

A method of making ducts having outwardly extending ribs formed integrally with the duct structure. Two tubes are formed from fiber reinforced resin materials, a uniform inner tube and a ribbed outer tube, then the inner tube is bonded with in the outer tube to form a high strength ribbed duct. An outer tube is formed by placing resin impregnated fibers over a cylindrical mandrel having an inflatable bladder on its surface, placing a plurality of spaced rings tightly against the outer surface, pressurizing the bladder to expand the tube into the spaces between rings to form low ribs, then gradually moving the rings toward each other to press the ribs therebetween and form thin upstanding ribs. The inner tube is formed by placing resin impregnated fibers on a slightly thinner mandrel that also has a surface bladder. When both tubes are formed, the mandrel is removed from the outer tube and the inner tube and mandrel are inserted therein and the inner tube bladder is inflated. The assembly is vacuum bagged and cured in an autoclave at a suitable temperature. The rings and mandrel are then removed and an integrally ribbed duct results. The thermosetting or thermoplastic resin impregnated fiber material may be placed on the mandrels by any suitable means such as filament winding, hand lay-up, or other deposition techniques.
摘要:
A fixed wing aircraft that can be converted to an automotive vehicle, comprising a generally rectangular planform fuselage having four wheels as in conventional automobile practice, and a telescopic wing which retracts into a housing in the roof of the fuselage. Telescopic horizontal and vertical stabilizers are provided at the rear end of the fuselage, as well as a retractable pusher propeller that is driven by an engine mounted on the front end of the fuselage. Both the propeller and the rear wheels are connected by a transmission box to the engine, so that either can be driven to operate the vehicle as an aircraft or as an automobile. On take-off, the rear wheels are partially retracted so as to place the aircraft at a proper angle of attack at the same time that the elevators are raised by pulling back on the control wheel. The control wheel is also connected to both the front wheels and the ailerons, and when turned 90.degree. to the left or right while in the flight configuration, causes the ailerons to move to their extreme angular positions while the front wheels are turned only a minimal amount. Further turning of the control wheel causes the front wheels to turn to their full angular position, without causing further movement of the ailerons. The wing is also movable longitudinally with respect to the fuselage so as to trim the aircraft for shifts in the center of gravity with varying load conditions.
