Autoflight Lifts Off and Transitions

Dean Sigler Electric Powerplants, Sky Taxis, Sustainable Aviation 1 Comment

Autoflight, the latest outlet for Tian Yu’s creativity, has demonstrated a successful transition from vertical lift to forward flight.  Yu, the founder and CEO of Yuneec, fielded a wide range of drones, motors, and eventually an ultralight electric aircraft under the Greenwings name. Yuneec Goes to Oshkosh He managed to obtain FAA approval for flights of his Yuneec e430, an electric two-seat lightplane, at Oshkosh in 2009.  At that time, Ed Warnock, CEO of the Perlan Project, called your editor to allow him to hear Yuneec powerplants humming audibly in their display area on Wittman Field. Eric Lindbergh tested the Yuneec e-Spyder, a derivation of Tom Pehigny’s design.  A pair of e-Spyders showed up at AirVenture in 2013, becoming the first electric airplanes to fly in formation at that event.  They were joined by Mark Beierle’s eGull in the ultralight area, an electric threesome that showed great promise. Yuneec faded from the American scene for a while, seeming to concentrate …

AutoflightX Returns Tian Yu to Forefront

A Long Developmental Background Tian Yu headed Yuneec, a pioneering firm in electric flight.  In 2009 his company had several motors and one- and two-seat aircraft flying.  They even received certification from the FAA for the two-seat E430 and shipped it to Oshkosh, where it made its public flying debut at that year’s AirVenture.   At the 2013 AirVenture, Greenwing, an affiliate of Yuneec, fielded two e-Spyders, which pulled a first with several two-electric-airplane formation flights.  Despite being a major supplier of hobby drones and an early developer of powered parachutes, Yuneec seems to have gone into a dormant state, with a new company, AutoFlightX, coming to the forefront. First shown as the BAT600 concept vehicle in  2017 (There seems to be an interim organization shift at the time), the craft was intended to be either hybrid or pure electric, and would have two forward and two rear coaxial positions for eight lifting propellers, one pusher propeller for flight , and …

China’s First Certified Electric Airplane Ready for Mass Production

China has seen Yuneec’s early entry into the electric aircraft field.  The parent company is now making drones and camera gear in China, but its Greenwing International subsidiary in Cable, California appears to be defunct, according to Bill Lofton’s EV Hangar.  Yuneec’s E430 two-seater and e-Spyder ultralight, all flown at the big AirVenture shows, will seemingly not come to market. A craft similar to the E430, the RX1E Ruixiang, is ready to go into mass production, however.  Developed by Shenyang Aerospace University in Shenyang City in China’s Liaoning Province, the long-winged two seater is the first electric aircraft certified by the Civil Aviation Administration of China (CAAC). Certification was a major accomplishment, according to Yang Fengtian, chief designer of the airplane.   “Unlike military aircraft and commercial jets, there are certain criteria that an electric plane must have before given permission to fly. The plane has to be light enough, and the batteries need to be efficient and reliable, and overall it has …

China Fields a Mass-Producible Electric Two-Seater

Dr. Seeley provided this link to a story from China Daily this morning.  The blog reported on this airplane last year following its public debut, but this year, two examples showed up at the 10th China International Aviation and Aerospace Exhibition, also billed as Airshow China.  Held in Zhuhai, Guangdong Province, the show featured daily flight demonstrations by one of the two aircraft on display. China Daily followed its headline with this optimistic kickline, “Huge markets are expected for the versatile, eco-friendly 2-seat RX1E, then reports, “China will soon put its first domestically developed electric aircraft into mass production, and designers expect a huge market at home and abroad.” “First” may be a dubious claim, with Tian Yu’s Greenwing International (Yuneec in China) e430 having flown five years ago, and having resumed flight testing in the US last year.  It may be true in the sense that Yuneec International now only shows drones, action cameras and powered skateboards on its …

Another Two-Seat Electric Airplane from China

Dean Sigler Uncategorized 1 Comment

China has a second two-seat electric airplane, the Rui Xiang RX1E, a high-wing, side-by-side craft similar to Yuneec’s E430.  Both are cantilever, high-winged configurations, with the Yuneec sporting a V-tail and the RX1E a T-tail.  Besides the difference in alphabetical empennages, perhaps something gets lost in translation, with several news items offering slightly different versions of this story. The English language version of the China News Service calls the RX1E China’s first electric aircraft, although it’s being introduced at least four years after the E430.   Most reports agree that it is designed by the Liaoning General Aviation Institute and that Shenyang Aircraft Manufacturing Co., Ltd. Under the Rui Xiang General name is responsible for manufacturing. Made of carbon fiber composite material, the RX1E uses a 10 kilowatt-hour lithium battery, enough for a 40-minute flight. Charging takes one-and-a-half hours and restores enough energy to make a 40-minute flight – all for about 5 yuan (80 cents). China News Service reports, “The …
