US$145,000 Elektra One and SunAirport hangar take recreational flying off-the-grid

PC-Aero's composite-construction, single-seat Elektra One electric Ultralight is one of the most efficient transportation devices ever conceived. It can fly for three hours, cruise at 160 km/h and has a 500 km range. The Elektra One's “SunAirport” hangar incorporates photovoltaic cells, providing zero emissions power for both the aircraft and hangar which will be sold together for less than EUR100,000 (US$145,000) from 2012. Significantly, the company's grand vision for taking recreational flying off-the-grid has just won it the Lindbergh Prize for Electric Aircraft. Read More

Google partners with NASA to sponsor Green Flight Challenge

Whether you view Google as a benevolent Internet overlord or the new 'Evil Empire', there’s no arguing that the search giant at least devotes some of its squazillions towards environmentally beneficial causes. Earlier this year the company invested US$168 million in what will be the world’s largest solar power tower plant and now it has partnered with NASA to sponsor the Green Flight Challenge that offers a prize purse of $1.65 million for the design of quiet, practical and energy-efficient aircraft.

World's first 'printed' aircraft is flown

One of the biggest selling features for 3D printers is the fact that you can just whip up a design using CAD software on your computer, then create a physical copy of it to try out – no special factory tooling required. Well, in order to illustrate the potential of the technology for the aviation industry, engineers from the University of Southampton have just designed and flown the world’s first “printed” aircraft. The entire structure of the unmanned air vehicle (UAV) was created using an EOS EOSINT P730 nylon laser sintering machine, which builds up plastic or metal parts through a successive layering technique.

Power Up gives paper planes an electric boost

Although they’ve been around for ages, for some reason paper airplanes have never been adopted for commercial use. It could be because they get soggy when wet, they lack any kind of flight controls, or because you would need an incredibly huge piece of paper in order to make one big enough to carry a human passenger. In any case, practical paper airplanes have now perhaps come a baby step closer to reality, with Tailor Toys’ Power Up electric power module for paper airplanes – it allows you to mount an electric propeller on your paper airplanes, so they can fly under their own power.

e-Genius flies into the record books, averages 100 mph over 211 miles

Just a couple of weeks after its maiden flight at the end of May, the e-Genius electric aircraft has now winged its way into the record books - managing to stay aloft for over two hours and maintain an average speed of 100 mph (160 kph). Its University of Stuttgart development team are now looking to improve on that performance, ahead of the 2011 Green Flight Challenge for which it was designed. Read More

EADS VoltAir all-electric aircraft concept unveiled in Paris

One of the displays that has generated a lot of buzz at the Paris Airshow 2011 is EADS’ ZEHST concept – a zero-emission hypersonic airliner, that could be whisking passengers from Tokyo to London in under 2.5 hours, by the year 2050. Sitting alongside the ZEHST model, however, is another EADS concept aimed at the more immediate future. It’s called VoltAir, and it’s a proposed all-electric airliner that could be flying within 25 years. Read More

eGenius electric aircraft makes successful maiden flight

An electric powered aircraft demonstrator has taken to the air for the first time with a 20-minute flight from Mindelheim, Germany. Intended for entry in the NASA funded CAFE 2011 Green Flight Challenge, the eGenius concept's single tail-mounted propeller is driven by an electric motor producing a maximum of 60 kW at 2,000 rpm and can travel at cruising speeds of up to 235 km/h (146 mph) with a range of up to 400 km (248.5 miles).
