Boeing engineers are in the process of replacing the wiring design used for the Dreamliners. It’s not a fix-it’s part of a plan to optimize weight and configuration of wiring bundles starting with plane number seven. The first six planes had flight test wiring that will be replaced as part of an overall refurbishing.As part of the overall materials revolution that the Dreamliner represents, some lightweight aluminum wiring will be used instead of copper. “We use both,” says Boeing spokesperson Lori Gunter, “There are different design considerations. We select the material that is appropriate for the intended use.”
Gunter did not provide specifics, but the design rules for aluminum and copper used as wiring are the following:
Aluminum is 50 percent lighter than copper and can save weight in the aircraft.
Copper bends more easily than aluminum.
Corrosion is a significant concern for aluminum wiring. Airbus engineers developed a special protection for aluminum wiring. There are also new specifications for connections.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
Researchers at the Missouri University of Science & Technology have designed a new nanoscale material that can transmit light faster than the 186,000 miles per second it usually takes to travel through air.
It has often been said that as California goes, so goes the nation. This spring, the state's wind power is setting energy generation records and solar energy generation is expected to rise sharply during the second half of 2013.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
