Indianapolis, IN--Just how safe can you make an aircraft from the threat of fire and yet shield passengers from unwanted noise? E-A-R Specialty Composites feels it can offer aircraft skin damping composites that do both.
Not only do the company's composites comply with the most stringent federal aviation burn tests, but they provide lightweight, high-damping performance on fuselage skin, bulkheads, and thin composite panels. The materials combine damping sheets and foams with an aluminum constraining layer and pressure-sensitive adhesive. Several different formulations enable general and commercial aviation companies to "tune" the materials for their specific temperature and damping performance requirements.
E-A-R has a long history of providing the damping materials to aircraft designers. Among its long list of customers: Cessna, Gulfstream, Learjet, Canadair, Airbus, Bell Helicopter, and McDonnell Douglas.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
Noting that we now live in an era of “confusion and ill-conceived stuff,” Ammunition design studio founder Robert Brunner, speaking at Gigaom Roadmap, said that by adding connectivity to everything and its mother, we aren't necessarily doing ourselves any favors, with many ‘things’ just fine in their unconnected state.
