Thanks for this, Chuck! We seem to be continuing our more than century-old love affair with automobiles. Maybe that is having a strong effect on our new designs.
I'm not a powertrain engineer, but perhaps yourself or others can help me out. It's my layman understanding that modern Diesel locomotives are Diesel-Electric hybrids, having a very efficient Diesel-fueled turbine that does one thing well... it turns an electric generator. Because the turbine does one thing well, it can be optimized for power, torque, fuel-consumption, etc. to produce electricity. The electricity is then used to power the traction motors that have no mechanical transmission or clutch -- all through the magic of magnetic field induction. The electric motors do one thing well, they turn the drive shaft. As far as power goes, Wikipedia lists that a modern Diesel locomotive can start moving trains weighing in excess of 15,000 tons. The M1 Abrams tank uses a 1,500-hp gas turbine engine, but uses a mechanical hydrokinetic transmission.
I continue to be perplexed as to why the Automobile industry does not integrate technology that has been successfully developed by other industries. I would have thought that General Electric would have used their turbine expertise to capture the automobile market by now. And I don't know about you, but as far as keeping the motorheads happy, if folks get excited about a "turbocharged" engine, I would love to be on the marketing team for the first "turbine jet" powered commercial automobile...
The 3D printing revolution seems to have a knack for quickly moving technology ahead by way of collaborative effort and even a little friendly competition -- all of course in the name of scientific advancement.
Advantech has launched a new series of motion-control I/O modules to meet the increased demands that come with more distributed industrial systems that require control of a growing number of axes and devices.
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
