Even following Boxing Day, we have a few items to re-gift to our faithful readers, and close out the season with four very light examples of electric aviation. A-I-R ATOS Felix Ruhle has been improving and refining a basic wing design for over a decade, growing a line of aircraft that range from simple hang-gliders to fairly sleek, self-launching, electrically-powered ultralight sailplanes. The A-I-R factory/showroom in Halblech, Germany, one of 18 dealerships around the world, fronts a lush green meadow and houses a plethora of ATOS wings. The ATOS wing, coming in a range of sizes, can be attached to seemingly anything from a simple jump-off-the-nearest cliff hang-gliding rig to refined, electrically-powered ultralight sailplanes. Under development for the last few years, the ultralight sailplane merits even A-I-R’s enthusiastic approval. “The newest development of A.I.R. is revolutionary! The foldable electric powered. nearly noiseless ultralight-aircraft is based on the proven Atos hang-gliding wings! With 3-axes-steering, real elevator, retractable landing gear and propeller, …
On to the North Sea, Electrically
Elektroweltrekordflug A team in Switzerland attempted an elektroweltrekordflug, an electric world record flight, hoping to set seven world records in one 700-kilometer trip. Flying a new, certified Pipistrel Velis, the team of Marco Buholzer and co-pilot Morell Westermann hoped to find their way into the Guinness Book of World Records for the following: • Lowest energy consumption (kWh / 100 km -62 miles) over 700km (434 miles) • Highest average speed over 700 km (km / h) • Highest flight altitude ever reached with an electric aircraft (meters – 3.280 feet – above main sea level) • Fastest climbing performance from 0-1000m / 1000-2000m / 2000-3000m (m / s) • Fastest average speed over 100km (km / h) • Smallest number of intermediate stops over a distance of 700 km (number of stops)` • Longest electrically flown route in 24/48/56 hours (km) The team made much the same point that Gabriel DeVault made in accepting the MacCready Prize at last …
Beethoven’s Fifth With a Guinness Chaser
Intel recently earned a Guinness World Record for lofting 100 drones at one time. To make it hard, they did it at night and to an orchestral accompaniment. Musical purists (your editor) might become vexed with the liberal reinterpretation of Beethoven’s score (the original symphony didn’t have a piano or a harp), and the added “bits” to a piece that’s been considered OK as-is for over two centuries. The orchestra played what they were given with great style, however, and the electronics wizards who put the aerial show together pulled it off with precision, playing well to the home crowd – apparently composed of Intel employees. One wishes Intel would release a complete performance video without the music-video-style editing and the reluctance to share the event with the outside world. Even with the “Making Of” video, many points of how it was done are not readily apparent. It looks as though the human operators do little other than regulate the height …
Chip Yates Breaks His Own Speed Record – Twice!
Your editor was on hand Saturday, October 5 at the California State Airshow at Mather Field, 20 miles east of Sacramento, mainly to see if Chip Yates could break his own electric aircraft speed record in his Long-ESA (Electric Speed and Altitude). He did break his previous Guinness Book of World Records speed of 202.6 miles per hour (and more recent speeds) on Saturday, but topped that on Sunday, with a quiet run of 216.9 mph. One Facebook fan wrote, “Incredible Plane… it’s a miracle.” The California Capital Airshow featured the usual crowd-pleasing noisy acts, with Chip being silently towed to runway’s end during fly-bys and aerobatics. His takeoff drew a hush from the crowd, straining to hear the soft whirring of the airplane’s Catto propeller. After a few runs in both directions over Mather’s main runway, he landed, taxied in, and took the airplane back to its display tent at the entrance to an aviation-related kid’s playhouse. He drew …
