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.

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 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.
