Dow-United Technologies Composite Products Inc. has developed a patented process for using braided composites to make jet engine thrust reversers, the devices that slow aircraft during landing. In the past, the primary section of the reversers, cascades, was made from magnesium castings or from aluminum, making the multi-part structures comparatively heavy and susceptible to fatigue or stress failure at critical points. The Dow-UT process uses braided carbon fibers and resins to create a much lighter part with substantially greater strength at the joints. In addition, the part comes off the assembly line as a single component, reducing ultimate assembly requirements, according to Lawrence Varholak, Dow-UT vice president, engineering and technology. The patent represents an enhancement of Dow-UT's Advanced Resin Transfer Molding (AdvRTM(TM)) process. FAX (203) 949-5009.
Two researchers from Cornell University have won a $100,000 grant from NASA to continue work to develop an energy-harvesting robotic eel the space agency aims to use to explore oceans on one of the moons of Jupiter.
Is the factory smarter than it used to be? From recent buzzwords, you’d think we’ve entered a new dimension in industrial plants, where robots run all physical functions wirelessly and humans do little more than program ever more capable robotics. Some of that is actually true, but it’s been true for a while.
