The U.S. Navy program to improve the reliability and seaworthiness of its Hovercrafts is moving forward. As first reported by Design News, Navy engineers are changing the technology used to attach the rubber-pleated skirts that contain high-pressure air that moves the craft above water. Newly developed fasteners can be replaced with regular tools, speeding replacement of damaged skirts. The new TineLok system has one or more tines that work in conjunction with longitudinal bolt thread channels to prevent counter rotation and loosening. The skirt manufacturer, Avon Rubber, has sent a purchase order for the first Navy Hovercraft replacement program. Orders to cover the rest of the fleet are expected to begin in May. There are 100 skirts on each Hovercraft and maintenance costs will be cut 25 to 30 percent. The first fasteners are all stainless: the nut, the tine and bolt. Tests are also being conducted on plastic versions that cut weight by 75 percent. Nuts and bolts are made from PEEK and the tine is made from glass-reinforced nylon. Rod is being machined for the sample run. The Army is looking at the technology for some of its weapons systems. It may also have applications for fastening of lighting in various applications.

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
