AutoFlight, the Chinese firm founded by Tian Yu (Yuneec), celebrated two milestones, although maybe not “firsts” as described in the company’s press releases. Both, however, are impressive and worthy of note. First Intercity Flight AutoFlight claims to have flown the first inter-city electric air-taxi demonstration flight between the southern Chinese cities of Shenzhen and Zhuhai. In an autonomous trip, AutoFlight’s five-seat Prosperity eVTOL (electric Vertical Take Off and Landing) aircraft flew the 50km (31 miles) route from Shenzhen to Zhuhai. The flight across the Pearl River Delta took just 20 minutes, a journey that would require three hours by car. For those with the funds to make the flight the difference in time is incalculable. According to the company, “This marks the first public flight of an eVTOL aircraft on a cross-sea and inter-city route, spanning across the bay where the Pearl River meets the sea, connecting the two southern Chinese cities.” In 2021, Australians flew a Pipstrel Alpha Electro …
VoltAero in Three Flavors
Jean Botti has had a remarkable career on two continents, culminating in his leadership of French company VoltAero, which offers its latest hybrid aircraft in three flavors. It’s all based on a modular design which shares a three-lifting-surface aerodynamic platform. As the company notes, “First to enter service will be the Cassio 330, with five seats and powered by the 330-kilowatt electric-hybrid propulsion system. VoltAero’s follow-on six-seat Cassio 480 will have an electric-hybrid propulsion power of 480 kilowatts, while the Cassio 600 is sized at a 12-seat capacity with electric-hybrid propulsion power of 600 kilowatts.” The 330 has a wingspan of 32 feet eight inches and a maximum takeoff weight of 4,255 pounds (1,930 kilograms). 480 and 600 models share a 40-foot, seven-inch span and longer fuselages to accommodate larger power trains, more passengers and cargo. This impressive array of planned aircraft stems from humble beginnings, a Colomban Cri-Cri (the world’s smallest twin-engine airplane designed by one of the engineers …
Atea Looks Like a Cessna Overhead
French company Ascendance Flight Technologies offers a four-seat design that combines hybrid propulsion with vertical takeoff and landing capabilities, and then scoots around on conventional wings. Etea’s technology seems a lot like that of Pipistrel’s 801 or several other eVTOLs. Some Historical Perspective The design team at Ascendance comes from Airbus, and claims to have made the first electric aircraft flight across the English Channel with the E-Fan 2.0. Your editor offers a few minor inclusions. First, as we reported on October 10, 2009, “Gerard Thevenot, a long-time championship-level hang-glider pilot, celebrated the centennial of Louis Bleriot’s flight across la Manche by flying his hydrogen-powered La Mouette hang glider over roughly the same route Bleriot took between Calais and Dover on August 6, 2009. Missing the centenary by a few days (Bleriot made the hop on July 25, 1909), Thevenot took an hour and seven minutes to duplicate the trip Bleriot managed in 37 minutes.” It was an Eck/Geiger propelled machine, …
MGM Compro Enjoys Good News in Europe and at Oshkosh
MGM Compro is a Czech company that seems to have a motor on half of every light electric airplane flying today. Their motors have powered Airbus’s electric Cri-Cri (four 15-kilowatt units), the firm’s e-Fan, Ruppert Composite’s Archaeopteryx, e-Volo’s Volocopter, and any number of motorgliders and light sport aircraft buzzing quietly over Europe, and soon, America. Certification in Europe Certification is usually the route to wide acceptance of a new motor, proof that the unit has passed some rigorous tests and is suited for use in aircraft. As Martin Dvorsky, Managing Director for the firm reports: We are really proud to announce that [the] MGM COMPRO complex propulsion unit just obtained [a] CERTIFICATE OF AIRWORTHINESS issued by [the] Slovak Federation of Ultra Light Aircraft. This certificate means that the glider and its system has positively passed all the safety and flight tests and can be legally operated by LSZ license holder (UL license counterpart).” Note the clever motor and propeller folding and retraction …
Airbus E-Fans 2.0 and 4.0 Dropped in Favor of E-Fan X
Much like waiting for the single-person ram-jet helicopter to show up in your garage, you’ll be left hanging for a two- or four-seat Airbus e-Fan to grace your hangar. Although not sharing the news in its “Innovation” or press release sections on its web site, Airbus has announced that it’s dropping plans to produce an E-Fan family of personal aircraft. It will move instead into developing a larger, more powerful aircraft, the E-Fan X, that could fly within three years. Airbus started with a four-motor rendition of the Cri-Cri, four MGM Compro units twirling contra-rotating propellers and producing 60 horsepower. Their “Innovation” program followed that with the tw0-seat E-Fan, and announced plans to build these in series at their cleverly named Voltair plant in southwest France. Airbus further suggested series production would begin on a four-seat E-Fan 4.0 touring aircraft. They showed a hybrid version of the E-Fan 2.0 trainer at Oshkosh in 2016. But they are moving on toward bigger …
Electric Cri-Cri Crosses English Channel
Michael Coates, the U. S. General Distributor for Pipistrel Aircraft, sent the following missive from Ivo Boscarol, General Manager and Founder of the Slovenian company, now in its 26th year. “Dear All, “It is my pleasure to inform you that our friend Hugues Duval after reading the information that Pipistrel was blocked in flying across the English Channel today became the first electric aircraft to cross the English Channel in his CRI-CRI E-Cristaline Electric aircraft. “As Duval already had the permanent permit to fly his aircraft there was no need to ask for a permit to fly over the English Channel, but only to fill the flight plan. It was possible to keep the flight information secret up to the end. “From the available information that we have, shortly after the flight announcement, an order was issued to stop him but he did not respect it and he successfully crossed the channel this evening, 9. July 2015 in the first flight …
AEAC Pulls in First 20 Deposits
Aero Electric Aircraft Corporation (AEAC) and Spartan College of Aeronautics and Technology made joint announcements about their signing a “Training Program Development and Deposit Agreement” for the school to reserve the first 20 delivery positions for “Sun Flyer” solar-electric training aircraft being developed by AEAC. This first such agreement by a major training program and an aircraft maker is a milestone for this new technology. The press announcement quotes Peter Harris, CEO of Spartan College, saying, “This agreement signifies our commitment to innovation and to serving the next generation of pilots. Spartan College is honored to be the first training school to formalize our collaboration on a complete training system that will make flight training more modern, accessible and economical than ever before.” The same announcement has George Bye, CEO of AEAC, thanking Spartan College for their collaboration and support. “Our goal with Sun Flyer is to achieve lower operating costs and enhanced safety features for a training airplane by …
