Jets

It's one thing to 3D-print something as advanced as a jet engine, but it's another to fuel it up and push the start button. That's the step that GE Aviation took when it recently fired up a simple jet engine made entirely of 3D-printed parts in a test stand normally reserved for commercial jet power plants.

Working with colleagues from Deakin University and CSIRO (Commonwealth Scientific and Industrial Research Organisation), researchers from Australia's Monash University have created the world's first 3D-printed jet engine. While they were at it, they created the world's second one, too. One of them is currently on display at the International Air Show in Avalon, Australia, while the other can be seen at the headquarters of French aerospace company Microturbo, in Toulouse. Read More
GE is looking to a new generation of carbon-fiber composites to make the fan blades for its GE9X jet engine. That engine is being developed for the Boeing 777X passenger airplanes that are set to enter service in 2020 and the new blades promise to provide larger, lighter engines with greater fuel efficiency.

Honda Aircraft Company has announced that its first production HondaJet has taken to the skies. The flight, which took place at HondaJet’s headquarters at Piedmont Triad International Airport in Greensboro, North Carolina, moves the executive jet aircraft closer to certification ahead of a planned entry into service next year.

Boeing has announced that it has retrofitted a number of retired Lockheed Martin F-16 fighter jets with equipment enabling them to be flown remotely without a pilot. In conjunction with the US Air Force, the company recently flew one of these unmanned jets, performing combat maneuvers and a perfect center line landing. Read More
In the Japanese animated film, Nausicaä of the Valley of the Wind, the protagonist explores a post-apocalyptic world riding on a jet-powered glider called a Möwe. When the movie was first released in 1984, a vehicle like that seemed like it could only exist in science fiction, but today one artist is determined to make it a reality. Kazuhiko Hachiya has spent the past decade designing and testing his own single-person glider and recently unveiled a full-sized model with a working jet engine. Read More
The Paris Air Show this week hosted the first foreign demonstration of the Russian supermaneuverable multirole fighter the Sukhoi Su-35. The specific aircraft on show is the latest iteration of the aircraft, designated Su-35S, 48 of which have been allocated to the Russian Air Force as they roll off the production line between 2011 and 2015. Visitors to the air show were treated to a display of the Su-35's impressive aerobatics, including a demonstration of the breathtaking Pugachev's Cobra maneuver. Read More
In the business world, time is money (and bragging rights). In April, the Citation X took said rights from the Gulfstream G650 with its maximum speed of Mach 0.935. Another contender could soon be on the tarmac in the form of the Saker S-1. With a design inspired by military fighter jets, US-based Saker Aircraft says its S-1 will cruise at Mach 0.95 and reach a top speed of Mach 0.99. Read More
Engineers at GE think they could have a revolution on their hands, thanks to the new jet engine they've been working with that runs hotter than any of its predecessors. When combined with some other design changes, they figure their so-called ADVENT (short for ADaptive Versatile ENgine Technology) design could improve fuel efficiency by as much as 25 percent, extend flying ranges by 30 percent, and boost thrust up to 10 percent over contemporary engines.
