Fastest Electric Airplane Emergency Landing Yet

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation 1 Comment

Chip Yates is used to going fast, having obtained a private pilots certificate in a mere two months, and test flying an electric Long-Eze conversion (Long-ESA) within two weeks of that, but he didn’t count on making the world’s fastest electric aircraft emergency landing during a record-breaking speed run at Inyokern, California’s desert airport on July 19. With only 58 hours in his log book, Chip managed to make the runway for a bumpy but great touchdown – a great landing being one following which you can reuse the airplane.  We’ve reported that event already, but Chip just released a great video of the white-knuckle event. To help document his record 202.6 mph flight, Chip’s airplane was well instrumented, carried several …

Dr. Brien Seeley, President of the CAFE Foundation, and Program Chair for the Personal Aircraft Design Academy (PADA), announces that the group’s catered buffet “networking” dinner will be followed by a special meeting for top aircraft designers, enthusiasts and aero engineers as part of AirVenture 2012 at Oshkosh, Wisconsin. His announcement highlights the following: “The dinner will be at 6:15 p. m. on Friday July 27 at the Memorial Wall Tent near the Air Academy Lodge, with the PADA meeting following at 7:30 PM in the air-conditioned Vette Theatre inside the AirVenture Museum, a short walk from the tent. “This year, we’ve made it easy to register online in advance for the limited seating available.

EMG-5 Electric Motorglider

This isn’t Brian Carpenter’s first time at the small airplane rodeo.  He’s built at least a dozen aircraft, designed several from scratch, and even entertained the hosts of TV’s Mythbusters series with a series of rides in his team’s ultralights. His latest creation at Tangent Aircraft is a sleek Part 103 ultralight that seems to break or bend the rules on several fronts, presenting a twin-pivoting-motored, Fowler-flapped, retractable-gear craft that would seem to be too complex to fall into legal 103 status – or even into something the average novice private pilot would be allowed to fly.  The 36-foot span and 105-square-foot wing would seem too fast to meet stall limits. Carpenter explained his design philosophy to your editor a …

Chip Yates Becomes World’s Fastest Person in an Electric Airplane

On July 19 at Inyokern Airport in California, Chip Yates and his Long-ESA electric airplane set an unofficial world’s speed record for battery-powered flight, hitting 202.6 mph just before a dead cell in the battery pack forced an emergency landing.  It was the airplane’s second test flight. Following a day of taxi tests, Chip, who has been taking flying lessons and recently achieved his Private Pilot’s license, set out to see how fast his 258-horsepower mount could go.  He has become the first person to break the 200 mph barrier for electric aircraft in level flight, beating the previous record by Hugues Duval at last year’s Paris Air Show in an Electravia-powered Cri-Cri.   Duval managed to hit 175 mph on …

It’s Official, It’s a Volocopter Video

Thomas Senkel of the German firm e-volo sends this video, the official promotional video for these multi-rotor vertical takeoff and landing aircraft at AirVenture 2012.  Better yet, the team will have at least their prototype machine on hand and many displays of future developments.  Note the modular structure of these vehicles at the end of the video. Innovation Hangar Alpha will house the VC2 Volocopter, successor to the VC1 and improved in many ways, including three pilates balls for bouncing your landing on.  The VC1 was the first “purely electrically powered, vertical take-off and landing (VTOL) aircraft and flew last October.  At least the pilot is under the spinning rotors on this version. Seriously, the designs represent a clever and …

Electric Lazair Progress

During a visit to the International Vintage Sailplane Meet at Harris Hill, New York, your editor was fortunate to be a guest of Dale and Carmen Kramer, who graciously showed their home, once that of Glenn Curtis, “The Father of Naval Aviation.” Now the Hammondsport cottage (as in Glenn Hammond Curtis), which overlooks the lake where Curtis flew his early amphibians, is home to a high-tech cottage industry, with Dale creating battery monitoring systems, “brain boxes”, and other elements of his electrical power system for ultralight aircraft.  He designs the schematic and printed circuit boards for the system, sends them off to a PCB manufacturer and hand mounts very small components on the finished circuit boards, a process that would …
