Ten-motor electric plane takes off

In seeking a compromise between helicopters and fixed-wing aircraft, engineers in recent years have opted for tilt rotors, but NASA has dusted off and improved on a tilt wing aircraft design that takes off and lands like a helicopter and flies like an airplane. Called the Greased Lightning, or GL-10, the unmanned prototype made a successful vertical takeoff and transition to horizontal flight at Fort A.P. Hill, not far from NASA's Langley Research Center in Hampton, Virginia.

Twin-fuselage Carplane prototype makes public debut

We've been teased with the prospect of a flying car for years now, with many designs, like the Terrafugia Transition, having been under development for some time but yet to arrive in garages or hangars. The Braunschweig-based company, Carplane hopes to square the circle with a twin-fuselage roadable monoplane that made its first public appearance in prototype form at the recent AERO show in Friedrichshafen, Germany.

X-47B completes first ever unmanned refueling exercise

The US Navy's X-47B Unmanned Combat Air System Demonstration (UCAS-D) aircraft has gone out on a high note (and added yet another acronym to the military lexicon) by conducting the first ever Autonomous Aerial Refueling (AAR) exercise. The autonomous aircraft rendezvoused with an Omega K-707 tanker plane off the coast of Maryland and Virginia, successfully taking on 4,000 lb (1,814 kg) of jet fuel as it completed the project's final test objective.

Siemens' world-record electric aircraft motor punches above its weight

Researchers at Siemens have created a new prototype electric motor specifically designed for aircraft that weighs in at just 50 kg (110 lb) and is claimed to produce about 260 kW (348 hp) at just 2,500 RPM. With a quoted power five times greater than any comparable powerplant, the new motor promises enough grunt to get aircraft with take-off weights of up to 1,800 kg (2 ton) off the ground. Read More

GE announces first FAA approved 3D-printed engine part

We've only just begun to see the huge impact 3D-printing technology will have on manufacturing, and the aerospace industry is a prime example. Earlier this year we saw the first example of a 3D-printed jet engine, now GE has announced the first 3D-printed part certified by the US Federal Aviation Administration (FAA) for a commercial jet engine. The fist-sized T25 housing for a compressor inlet temperature sensor was fabricated by GE Aviation and will be retrofitted to over 400 GE90-94B jet engines on Boeing 777 aircraft.Read More

DARPA looks at "system of systems" to maintain US air superiority

Modern warfare is a constant arms race of measures and countermeasures, but with development cycles taking decades and costing billions of dollars, it's not uncommon for military technology to become obsolete by the time it's deployed. To address this dilemma, DARPA's System of Systems (SoS) Integration Technology and Experimentation (SoSITE) program aims at replacing monolithic weapon systems with a more flexible cross-platform approach.

FAA loosens rules for commercial drone flight

If you want to operate your drone for commercial reasons in the US at the moment, there are considerable hoops you'll need to fly through first. But an announcement today from the Federal Aviation Administration (FAA) is set to make this process more efficient, throwing a blanket approval over operators that meet a certain criteria.

Could this 18-motor wing be the future of electric aircraft?

It might look like it was designed by a six-year-old, with 18 motors crammed onto a too-thin wing, but the Hybrid-Electric Integrated Systems Testbed (HEIST) experimental wing demonstrator could be the future of electric aircraft. A key component of NASA'S Leading Edge Asynchronous Propeller Technology (LEAPTech) project, it is designed to test whether electric propulsion can allow for a tighter wing design leading to greater efficiency and safety.Read More
