By Beth Stackpole – While composite materials deliver superior aerodynamic qualities, they introduce complexities into the design, particularly around blending surfaces between two adjacent parts and in accurately determining the thickness of component parts. Prior to using CATIA and the integrated Composites Design tool, the Pipistrel team struggled with blending a surface such as a sharp wing structure with a round surface like that associated with a fuselage. Traditionally, in an example like that, the team would produce the wings and fuselage separately and then join them together by hand. Because the process was so complex and nearly impossible to replicate in a drawing, designers were stuck with more of a trial-and-error process, which was time consuming and often didn’t produce the desired results. “The fact that we can define the outside aerodynamic shape on the computer versus describing what we want technically to build a part has tremendous benefits,” Tomazic explains. “There’s no more problems with fitting – if parts fit on the computer, they fit in real life.” more> http://tinyurl.com/25dwutj

By Marc Ambinder – GE’s argument — that developing a second engine is a good thing — is solid, so far as it goes. Yes, it wouldn’t be that expensive.
But these arguments completely miss the point. The point is that business as usual is no longer business as usual. The entire process is changing. Indeed, in the future, the Pentagon doesn’t want contractors to manage big programs like the JSF — they want to do it themselves. more> http://bwbx.io/tFy2

By Beth Stackpole – At the heart of the latest release of the NX CAD system is new HD-PLM technology, a framework Siemens PLM Software says will transform the existing PLM paradigm into a high-definition, decision-support system that proactively guides users through the collaborative design process.
Borrowing key Web 2.0 and user interface principles and built on modern technologies like role-based portals and Service Oriented Architecture (SOA), HD-PLM delivers a more intuitive, personalized user experience with PLM to aid in decision making throughout the entire product lifecycle, according to Eric Sterling, Siemens PLM Software’s senior vice president of global marketing. more> http://bwbx.io/in3l

By Heidi N. Moore – Holders of commercial mortgage-backed securities — which are bundles of loans on hotels, office buildings, malls and apartment buildings — have found that unlike other asset classes, there are and were investors willing to buy and sell their holdings, essentially because they needed to, for returns or liquidity. more> http://bwbx.io/zJ0z

By Randall W. Forsyth – If you’re a builder looking for a construction loan to build a house or a prospective buyer of that house applying for a mortgage, good luck getting a bank to stamp “Approved” on your application. But if you run a hedge fund that trades securities back by the mortgages on such houses, getting financing for those positions is no problem.
In the case of the big banks—which now includes Goldman Sachs (GS) and Morgan Stanley (MS)—they lend to their prime-brokerage customers, such as hedge funds, to support their lucrative derivatives, currency or securities trading operations. More lucrative, apparently, than the mundane business of making business loans. more> http://bwbx.io/YwXS
