Precision Measurement and Inspection Ensure Quality of SLS Rocket Panels

Reverse engineering and inspection software Verisurf Software Anaheim, CA 714-970-1683 www.verisurf.com In spaceflight, the first eight minutes are critical. This is when the greatest opposing forces of thrust and gravity are impacting the launch vehicle. The new NASA Space Launch System (SLS) will weigh 5.5 million pounds at liftoff, or roughly the weight of eight fully loaded 747 jets. Everything comes down to weight and the integrity of design and fabrication to insure success. Today, it costs $10,000 to send one pound of payload into orbit; since the entire launch vehicle makes the trip to low-Earth orbit, its net weight is a big consideration. The lighter the launch vehicle, the greater the payload can be.

Magnetic Fluids Deliver Better Speaker Sound Quality

NASA’s liquid magnetization technology helps Sony increase sound amplitude while reducing distortion. In the early 1960s, NASA scientists were trying to move fuel into an engine without the benefit of gravity. A scientist at Lewis Research Center (now Glenn Research Center) came up with the idea to magnetize the liquid with extremely fine particles of iron oxide. That way, fuel could be drawn into the engine using magnetic force.

Editor’s Choice

For 20 years, I’ve been interacting with engineers in all different industries as the Editorial Director of NASA Tech Briefs. I’ve talked with our readers about their work and the products they use. Many of them are CAD users, and many of them are unhappy with some aspect of their CAD software.

Watching Alloys Change Could Lead to Better Metals

If you put a camera in the ice machine and watched water turn into ice, the process would look simple. But the mechanism behind liquids turning to solids is actually quite complex, and understanding it better could improve design and production of metals. A recent investigation aboard the International Space Station (ISS) involved experiments using transparent alloys to observe microstructures that form at the point the material solidifies.

3D Printed Jet Engine Debuts

Researchers at Monash University in Australia have produced a 3D printed jet engine. Professor Xinhua Wu, head of the Monash Centre for Additive Manufacturing (MCAM), is leading initiatives to develop 3D printing. The Centre is working to provide answers for manufacturers seeking new manufacturing processes that make components lighter and cheaper than traditional ones, but without any reduction in performance.

Product of the Month: April 2015

Onshape, Inc., Cambridge, MA, introduced Onshape, the first full-cloud 3D CAD system with built-in data collaboration and management that lets all members of a design team work together using any Web browser, phone, or tablet. Using parametric and direct modeling techniques, the CAD system and data live in the cloud and are not copied, so everyone works on the same master at all times, eliminating checkouts, file copies, and overwriting. The product also eliminates installations, license codes and servers, service packs, and add-on PDM systems. Each user works on the same version of Onshape, so teams can access the same documents simultaneously. Access is controlled by the document owner, so each user sees visual indicators when others are working within the same document. Onshape allows users to perform all CAD work — not just view and markup — from a mobile device. The mobile apps are optimized for phones and tablets, allowing flexibility to access, collaborate, and edit CAD data anytime, anywhere, on any device. Both Free and Professional plans are available, with both providing access to full functionality. For Free Info Visit http://info.hotims.com/55588-120

PLC-Based Robotic Controls Versus OEM Robotic Controls

As more manufacturing facilities and distribution centers discover the benefits of robotic material handling solutions, the decision of how best to control the robot must be made. While robot original equipment manufacturers (OEMs) offer their own tightly integrated controller, recent developments have enabled control by a Programmable Logic Controller, or PLC. For facilities where PLC-based controls are already used in other machine control applications, the benefits of using one for the robot as well may be a wiser choice than the OEM controller. Let’s review PLC-based robotic control to help you determine if it’s the best choice for your application.
