I am a Test Engineer. I have the unfortunate responsibility to task aviation parts to break in my bench vs. in the airframe. While I make many engineers unhappy I can see a pattern that the ones following our engineering procedures to the letter rarely make a mistake (which is 99% of our engineers). Redesign is a very low percent and it occurs prior to product release. Also another pattern I see is in the cost reduction budget. While many might think that cost reduction might produce unreliable product I disagree with that mentality. I see that the larger cost reduction budget generally introduces better practices and also fixes previous problems that might not have been spotted. It directly relates to more reliable products as well as better engineering practices. It forces you to revisit old designs and improve them as well as produce them at a lower cost. It's a win-win.
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
