Optimize mechanical misalignments, get hidden benefits
C-Flex Couplings combine the best qualities of disc, beam, and bellows couplings in a unique and economical new design. Made to couple two rotating shafts together, these couplings can accommodate large misalignments while transmitting high torque loads with zero backlash. Benefits include lower energy usage and less-frequent bearing failure, since less stress is placed upon bearings. Constructed using high-strength hardened stainless steel or glass impregnated polyamide flexures, these couplings require no maintenance and provide years of trouble-free life, even in contaminated environments. Flexible Pivot Bearings and Super Plastic Torsional Damping Couplings also available.

How pressure-sensitive paint helps improve hypersonic flight predictions
In a key to understanding how intermittent turbulent spots shake an aircraft flying at Mach 5 or greater, a Sandia National Lab aerospace engineer has, for the first time, characterized the vibrational effect of the pressure field beneath one of these tiny hypersonic turbulent spots.

High-altitude satellites may bring GPS navigation to Moon
Four Magnetospheric Multiscale spacecraft recently broke the world record for navigating with GPS signals farther from Earth than ever before. The success indicates that NASA spacecraft may soon be able to navigate via GPS as far away as the Moon, which will prove important to the NASA Gateway, a planned space station in lunar orbit.

New plastic can be recycled again and again -- into any color, shape, or form
Light yet sturdy, plastic is great -- until you no longer need it. Even the most recyclable plastic, PET, is only recycled at a rate of 20 to 30 percent. But a team of researchers has designed a recyclable plastic that can be disassembled into its constituent parts at the molecular level, and then reassembled into a different shape, texture, and color again and again -- without loss of performance or quality. Wow!

Wheels History:
One-armin' the '52 Fetzenflieger with Porsche factory racing engine

There have been a lot of racing legends throughout the history of motor sport, but none can quite compare to Austrian driver (and mechanical engineer) Otto Mathé, who, despite having only one functional arm, not only drove to victory in each of the 20 races he entered in 1952, but also built his own cars exclusively featuring Porsche engines. In the mid-1950s, he became well known for building, driving, and winning in an unusual vehicle dubbed the "Fetzenflieger."

8 ways to improve your sheet metal parts
All sheet metal parts start out flat. And no matter how convoluted or complex their final shapes may be, the wall thickness of those parts must be uniform throughout. Engineers from Protolabs share their eight quick sheet metal design tips, focusing on material and finishing options along with design elements like bends, reliefs, holes, and slots when developing your metal components. Really useful info.

Piezo motor technology: Questions answered
There's a new kind of piezo motor in town, and it's got legs. The Piezo LEGS rotational motor is a direct-friction drive that provides precise motion without any mechanical play or backlash. There are no gears or transmission, so changing the direction of the motion will introduce no error. The simple Piezo LEGS motor is also extremely stiff. Find out the answers to frequently asked questions about this exciting motor technology available from the FAULHABER Group.

Water park's 5D movies require special pneumatics
Can you imagine going to the movies in a bikini or swim trunks? You can really do it -- you don't have to dream it. A new form of movie experience at an Abu Dhabi water park involves the audience sitting in special moving seats with various integrated effects taking place around them and on them, including real floods that fill up the theater. Emerson's AVENTICS pneumatic components play a key role in making the magic happen.

Compact spiral elevator opens up conveying possibilities
FlexLink AB has upgraded its compact spiral elevator even further with in and out feeds. With a total of six configurations, this solution increases your possibilities and fits different production line layouts even better. The spiral gives you increased access to the production floor, offering a 40 percent smaller footprint compared to the most common solutions on the market -- and the possibility to transport goods vertically, bridging the differences of height. The spiral can be installed in a few hours and ensures smooth running, low noise, and long service life.

New lead screw configurator allows for quick design
igus has developed a new lead screw configurator that allows customers to design their own lead screw and associated drawing in minutes without in-depth technical knowledge and CAD software. The new tool even directly checks the plausibility of the configuration. Trapezoidal, high helix, or metric thread lead screws in combination with nuts made of iglide high-performance polymers ensure lubrication-free adjustment for long-lasting and smooth-running applications. The company runs its North American operations out of Providence, RI.

Hot Concept Cars: Kia HabaNiro EV
One of the most popular vehicles at the New York Auto show at the end of April was not an American muscle car, a huge pickup truck, or even a super-luxe sedan. It was a hot little concept cleverly named a HabaNiro by Kia, and it got many people excited about what the near future of all-electric cars really could look like.

Fun! NIST unidentified museum objects
From time to time, the National Institute of Standards and Technology publishes a blog entry on a new batch of "Unidentified Museum Objects" -- weird gizmos and doodads from the organization's underground storage shelves. Some of these thingamabobs may have been there for the better part of a century. The problem is, nobody knows what they were used for. Maybe you have a clue.

How GE's 'leaky engine' became ubiquitous
"Over four decades, the F404 developed and produced at GE's Lynn, MA, plant has powered thousands of F/A-18 Hornets for the U.S. Navy and other Allied nations, as well as other aircraft applications, most notably the U.S. Air Force (USAF) F-117 Stealth Fighter," according to GE Aviation. The J101 design was dubbed a "continuous bleed" or "leaky" engine at GE "because a continuous flow of air from the fan cooled the afterburner and nozzle downstream. This clever design feature allowed the engine to operate at higher temperatures and pressures, but with less installed drag."

New Spirawave® Wave Spring Series
Smalley's Nested Spirawave Wave Springs are now available as standards. These flat wire springs are coiled in parallel with multiple turns to produce high loads, and are ideal for applications requiring high forces in tight spaces. When replacing single-turn wave spring stacks with one nested spring, misalignment and uneven loading are eliminated, simplifying assembly. Standard or custom, Smalley will provide you the right part, in the right material, with No Tooling Charges™.
Watch the Smalley video for more information.
