Boeing is making another significant design change to the Dreamliner to accommodate yet another problem that had not been previously disclosed. Boeing ordered suspension of fuselage production at an Italian subcontractor in June when it became apparent small wrinkles were forming in the composite skin. Spokesperson Lori Gunter tells Design News: “We have designed a fix for the barrels that have already been built-a simple patch that is installed from the outside of the airplane. We are completing a permanent fix to the design that will accommodate the changes in the stringer without needing to install a patch-this basically consists of adding a few layers of composites in key areas of the fuselage.”
As reported in Design News, Boeing engineers are also redesigning the area where the wing mounts to the fuselage. The Dreamliner is already two years behind schedule.
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
