Curtiss-Wright Awarded Laser Peen Contract

Photonics.com
Jan 2008
Curtiss-Wright Corp. of Roseland, N.J., a manufacturer of products for motion control and flow control applications, announced today that its Metal Treatment segment has been awarded a contract from The Boeing Co. to establish a laser-peen-forming production cell inside Boeing's Frederickson, Wash., facility. The cell is planned to be in production during the second quarter of 2008 and would initially be used for shaping the complex curvatures of some wing sections of the new Boeing 747-8. Curtiss-Wright's laser peening process is based on neodymium glass laser technology originally developed at the Lawrence Livermore National Laboratory. It imparts deep compressive stresses on the surface of metal parts, which can then be used to precisely form metal panels into their desired shape.


GLOSSARY
glass
A noncrystalline, inorganic mixture of various metallic oxides fused by heating with glassifiers such as silica, or boric or phosphoric oxides. Common window or bottle glass is a mixture of soda, lime and sand, melted and cast, rolled or blown to shape. Most glasses are transparent in the visible spectrum and up to about 2.5 µm in the infrared, but some are opaque such as natural obsidian; these are, nevertheless, useful as mirror blanks. Traces of some elements such as cobalt, copper and...
photonics
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
