Long-range sniper system is the BOSS
What does it take for an Army sniper to accurately hit a person-size target at extreme ranges? The Army thinks it may have the answer to this challenge in a new integrated fire control sighting system for military sniper weapons called the Ballistically Optimized Sniper Scope (BOSS).

New turboprop delivers jet-like simplicity to pilots
GE Aviation engineers used 3D printing to combine 855 aircraft engine components into just a dozen parts. The simpler design reduced weight, improved fuel burn by 20 percent, and gave the turboprop engine 10 percent more power. The new plane design also has single-lever engine control.

Air spray: The comeback of stunning military aircraft paint jobs
Eight Oregon Air National Guard members received a call to arms. Their wing commander handed them an assignment, stressing high priority. They worked 33 consecutive days, some pulling night shifts. Their orders: Paint a Boeing-built F-15 Eagle jet fighter in a manner that would elevate base morale at Kingsley Field in Klamath Falls, OR, and commemorate the Air National Guard’s 75th anniversary across the state.

Aluminum treads on Mars Curiosity rover show open breaks and tears
A routine check of the aluminum wheels on NASA’s Curiosity Mars rover has found two small breaks on the rover’s left middle wheel -- the latest sign of wear and tear as the rover continues its journey, now approaching the 10-mile mark. NASA lays out the problem, and Designfax delves a little deeper into the cause.

U.S. Navy electrifies aircraft carrier catapult
It may be "full steam ahead" for the U.S. Navy's newest aircraft carrier, the USS Gerald R. Ford, but it won't be the catapult that will be steam powered. Less than one week after it was commissioned, the Ford launched and recovered its first fixed-wing aircraft in July using the Navy's new electromagnetic launch system (EMALS) and advanced arresting gear (AAG) system.

Mercedes brings yacht style to the Maybach 6 Cabriolet concept
If Thurston Howell III dreamed of the far-distant future while shipwrecked on "Gilligan’s Island," he probably imagined tooling around the mainland with Lovey in something like the yacht-inspired Vision Mercedes-Maybach 6 Cabriolet concept. Recently displayed at Monterey Car Week in California, the 750-hp (550-kW) electric hard-top convertible is luxurious, pretentious, exaggerated, and a real head turner -- but it's full of clever and impressive design details too.

WWII Engineering: The saga of the bird-brained bombers
During World War II, the National Institute of Standards and Technology (NIST) was among those working intensely to develop guided weapons to help the Allies win the war. But before the advent of satellites and GPS, laser targeting, or even radar, how would one guide a bomb? Why, trained pigeons, of course.

Top Toolbox: Fastest way to dry your hands? FloEFD investigates
Have you ever wondered what’s the fastest way to dry your hands when using one of those air-shooting hand dryers in a public restroom? Should you rotate your hands or leave them in one place? What position is most efficient? Proving that modeling everyday challenges is fun and insightful, Robin Bornoff from Mentor Graphics tackles these questions using the full-featured 3D fluid flow and heat transfer analysis simulation tool called FloEFD.

Top Toolbox: Metal tape measure technology grows up
When first-timers see the Zippermast rise into the air from an unmanned vehicle, they are amazed by how high it can be extended. Inspired by the lowly metal tape measure design, the compact and super-sturdy Zippermast consists of three interlocked steel tapes that also function like a locking zipper, lifting cameras and sensor equipment up to 40 ft in the air. A small DC motor from FAULHABER provides the unique design with reliable retraction and extension, all incorporated into an amazingly small base housing.

Top Tech Tip: Torque sizing criteria for servo motors
Servo motors and controllers need torque sensors to operate closed-loop feedback systems. The engineers at FUTEK understand that choosing the right sensor for your system can be complicated, so they've compiled three easy steps in their latest white paper to help you narrow down your search.

Top Product: World's darkest spray paint
A whole range of products can now take advantage of the world's blackest coating, Vantablack, thanks to the development of a new spray version called Vantablack S-VIS. It is easily applied at large scale to virtually any surface. Vantablack's carbon nanotube matrix structure absorbs virtually all (99.8%) incident light, enabling precision optical systems to be optimized. The material’s developer, UK-based Surrey NanoSystems, has mimicked the performance of its original Vantablack with this new version that can be sprayed onto objects, rather than deposited using a chemical vapor deposition (CVD) process.

Top Product: Alternative precision linear motion system
With high speeds, incredible accuracy, and zero backlash at unlimited lengths, Nexen’s patented Roller Pinion System (RPS) overcomes the limitations of conventional rack and pinion, ball screw, and belt-drive systems. The RPS offers longer life, less maintenance, 99% efficiency, and can run without lubrication.

Top Product: Zinc foam with cost-saving feature
Goodfellow has announced the availability of two variants of zinc foam: 99.99% zinc deposited on a polyurethane foam and ZAMAK 410 Zn/Al4/Cu1/Mg0.04 zinc alloy foam with solid ligaments. Both combine the versatile properties of zinc or its alloy with the functional benefits of a foam. This combination should be of particular interest to design engineers working in the fields of heat exchangers, catalyst substrates, energy absorbers, filters, and mixers. Cost-saving feature: For the variant deposited on a polyurethane structure, it is possible to design the finished component in the base foam before metalizing, avoiding post-machining and thereby reducing costs. Editor's note: Goodfellow copper foam has been a favorite of Designfax readers for years, so check that out too.

Giant 28-ft chainsaw widens Italian tunnels
If you are looking to widen two highway tunnels and don't want to disrupt traffic, what do you do? If you are Italian tunneling-machines and systems-maker Palmieri Group, you design and build a giant 28-ft (8.5-m) chainsaw that can handle cutting earth and rock, and you mount it on a huge, movable arc track. That way, you can install a fully enclosed protective lane tube for cars and trucks to use under the arc as you move forward. In 2016, the new machine had to endure a lot of dust, heat, and moisture. Palmieri specified a Hägglunds hydraulic motor and a closed hydraulic system by Rexroth, through which the fluid was pumped using two axial piston variable pumps. Magnifico!

NASA's Mars 2020 mission performs first
supersonic parachute test

An ambitious NASA Mars rover mission set to launch in 2020 will rely on a special parachute to slow the spacecraft down as it enters the Martian atmosphere at over 12,000 mph. Preparations for this mission have provided, for the first time, dramatic video of the parachute opening at supersonic speed.

Honey, I shrunk the V-8 engine!
Borrowing from the classic design of a V-8 engine to achieve high push/pull and holding forces, patented piezo actuator technology and linear stepping motion design principles come together to create the fastest and strongest non-magnetic drive of its class size. These piezoelectric motors are self-clamping -- at rest or in steady-state mode, they automatically hold the position without any need for power. Learn how this technology can be used in your application.

Pushing the limits of motorcycle design and manufacturing
Matt Chambers, founder and CEO of Confederate Motors, talks about the impact that 3D Systems' Quickparts rapid parts and prototypes service has on his design-and-build business. With the exception of some engine components, wiring, wheels, tires, and lighting, 3D Systems makes every part of the super-boss P51 Combat Fighter motorcycle, saving a tremendous amount of time and hassle for Confederate Motors by being able to consolidate part production with one primary vendor.
