Two aeroacoustic wind tunnels have been inaugurated by Renault (www.renault.com), Peugeot Citroen (www.peugeot.com), and the French Institute of Engineering Studies in Saint-Cyr l'Ecole in France, to investigate on the reduction of the aerodynamic drag of vehicles, aerodynamic noise for the comfort of passengers, dynamic stability of the vehicle, as well as the effects of side winds. The main tunnel will measure 258 ft2 with a ¾ open jet design that is large enough to accommodate minivans. Wind velocity in the main tunnel can reach as high as 149 mph.
A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
