Medium Wave Infrared Heater for High-Speed Fiber Placement

2007-09-17
2007-01-3842
Electroimpact, in cooperation with a large airframe manufacturer, has developed Automated Fiber Placement equipment capable of depositing material at speeds in excess of 2000 inches per minute. As the machine lays down each new ply of material, the area forward to machine motion is heated just in advance of pressing the tape against the substrate. A fast-reacting, high-power infrared emitter heats this area quickly and safely. The design of these heaters is the subject of this paper.

2004-01-2806
The Horizontal Automated Wing Drilling Equipment (HAWDE) machine is an enabling technology for automated drilling of large aircraft parts. HAWDE is a five axis drilling machine that operates over the upper and lower surfaces of eight wings, each more than 40 meters long and four stories tall. The machine accesses the entire A380 wing using a combination of elevators and a machine transporter that carries the machine from surface to surface. HAWDE drills holes in spars, butt splices, and rib feet in the wing box final assembly jigs for A380.

A Flexible Development System for Automated Aircraft Assembly

1996-10-01

McDonnell Douglas Aircraft in St. Louis, MO manufacturers various transport and fighter military aircraft such as the C-17 and the F/A-18. With shrinking military budgets and increased competition, market forces demand high quality parts at lower cost and shorter lead times. Currently, a large number of different fastener types which include both solid rivets and interference bolts are used to fasten these assemblies. The majority of these fasteners are installed by hand or by using manually operated C-Frame riveters. MDA engineers recognized that in order to reach their goals they would be required to rethink all phases of the assembly system, which includes fastener selection, part fixturing and fastener installation methods. Phase 1 of this program is to identify and to develop fastener installation processes which will provide the required flexibility. The EMR fastening process provides this flexibility.
