All-electric SportsStar EPOS makes maiden flight

Czech light aircraft specialist Evektor-Aerotechnik has announced the maiden flight of its all-electric SportStar EPOS two-seater airplane. On March 28, the EPOS made two back-to-back flights with a combined flight time of 30 minutes. The EPOS, the name of which derives from "electric-powered small aircraft," is powered by a single 50-kW Rotex Electric motor and features what its makers describe as a "new trapezoidal wing of extended span," which is 10.46 m (34.3 ft) tip to tip.

Top 10 things you CAN'T have for Christmas 2012

The end of the world might not be nigh, but the end of the year is, which means it's time once again for our annual look back at some of the most outrageous examples of new technology to have crossed our desk during 2012. So be as naughty or nice as you like, because even the most eloquent of letters written to Santa Claus won't elicit a response if any of these items appear in the fine print.Read More

Chip Yates all-electric Long-ESA aircraft breaks 200 mph speed barrier

The last time we caught up with electric vehicle pioneer Chip Yates, he was in the latter stages of his pilot training that would allow him to fly a yet-to-be-designed electric aircraft from New York to Paris along the same route taken by Charles Lindbergh. Having already claimed the crown for the world's fastest electric motorcycle in 2011, he has now stamped his seal on the title of first manned electric airplane to break the 200 mph barrier in level flight.Read More

Stalker UAS flight time improved by 2,400 percent using laser beams

Late last year, DARPA researchers upped the standard two-hour endurance of Lockheed Martin’s Stalker small unmanned aerial system (UAS) by a factor of four using a propane-fueled compact solid oxide fuel cell (SOFC). Now the flight time of the aircraft has been improved by a whopping 2,400 percent, with a test flight lasting more than 48 hours using a laser power system to wirelessly transfer power to the UAS from the ground.Read More

FlyNano achieves first test flight

Last April, we told you about the FlyNano – a single-occupant petrol/electric microlight amphibious aircraft being developed by a Finnish aeronautical firm of the same name. At the time, some readers expressed skepticism, rightly pointing out that there was no video of the plane actually flying. That changed this week, however, as the company posted a video of one of the prototype’s first test flights. Read More

All-electric aircraft to emulate Lindbergh's historic transatlantic flight

Eighty five years ago, Charles Lindbergh became the first pilot to successfully fly from New York to Paris non-stop, claiming a substantial cash prize and securing a place in history in the process. Now another world record holder, Chip Yates, has announced plans to take on the same aviation challenge ... but this time the aircraft making the 3,600 mile non-stop flight will be all-electric. The ambitious project is still in its early stages but the Flight of the Century team has already developed a patent-pending battery deployment solution to replenish depleted batteries while the aircraft is in flight.Read More

Volta Volaré's futuristic GT4 e-hybrid airplane available for order

Volta Volaré has begun taking orders for its four-seater GT4 hybrid private aircraft it calls "the most technologically advanced private aircraft available anywhere on Earth." Though the GT4 is perfectly capable of taking off and flying powered only electrically, a gas engine starts when the airplane's battery drops to 25 percent capacity in order to recharge it mid-flight. Surprisingly, perhaps, Volta Volaré makes a strong economic case for the GT4. Because the powertrain has only one moving part - the motor or "EViation Drive" - the company claims the need for maintenance is reduced significantly, offering increases in TBO (time between overhaul) by up to a factor of ten when compared to a combustion engine.Read More

ELHASPA Electric High Altitude Solar Powered Aircraft makes first flight

There's no doubt that satellites have become an essential part of our daily lives, making things like communications, navigation, weather forecasting, and remote imaging all possible. Unfortunately, the orbiting objects can be very expensive, both to build and to launch into outer space. For some of the functions that they carry out, however, an actual satellite isn't required - a high altitude, long endurance (HALE) aircraft could also get the job done, and at a much lower cost. Some such aircraft have been powered by conventional fuel, batteries, and hydrogen. On November 13th, though, the Electric High Altitude Solar Powered Aircraft (ELHASPA) joined the ranks of HALE aircraft to fly using nothing but the power of the Sun. Read More
