At least two Cessna 337s are flying on modified power systems – one with Ampaire in various locations around the world and one in France.  VoltAero’s French Cessna push-pull twin has been turned into a tri-motor, with twin motors sprouting from the front of the craft’s tail booms.  Like its American counterpart, VoltAero’s machine is a test bed for the planned power system that will mark its successor.  VoltAero reveals its coming aircraft will feature a “barrel”-type arrangement of three 60 kilowatt electric motors ringing a central internal-combustion (thermal) engine.  Jean Botti, CEO of VoltAero, explains the motor configuration is well-proven, having flown in the Cassio 1 demonstrator (the Cessna) since October last year.  Since then, it’s been flown around …

Joseph Oldham Beams an American Record

A new “record” for an electric aircraft flight probably won’t make the books, but was a great sales opportunity for the off-grid charging system that accompanied it. 21 electric airplane records exist in the list of Federation Aeronautique Internationale-recognized achievements.  At least one was set in 2012 by Jean-Luc Soullier in his Colomban MC-30 Luciole (Firefly) – 189.87 kilometers per hour (117.98 mph) over a 15 kilometer closed course using a Lynch-type brushed motor.  It topped his record in February of the same year of 136.4 kph (84.76 mph). For a while, Soullier held records for altitude and distance, but these were eclipsed by others.  At the time, your editor encouraged beating these records, since they were early efforts in …

Take Heart!  United We Fly!

Heart Aerospace, on the airport at Gothenburg Airport in southern Sweden, wants to bring inexpensive, four-motor electric flight to the masses.  With $35 million (29.4 million euros) in recently acquired backing, the small team at Heart is working toward making a 19-passenger, four-motor airliner a reality.  Their ES-19 is a single-aisle design with eight-rows of single seats and three-seat row at the cabin’s rear. Those 19 seats are a selling point, with United Airlines signing purchase contracts for 100 of the $ 9 million machines.  Mesa Airlines follows suit for another 100 and Finnair, Finland’s national airline, has expressed interest in another 20.  Funding from Bill Gates’ Breakthrough Energy Ventures and other investors totals over $35 million.  For a niche …

Going Big and Bigger with Hydrogen

Two companies promoting hydrogen power for aircraft are upsizing their aspirations, with aircraft  hauling four to up to 40 passengers.  Both have ambitious timelines. ZeroAvia, operating in Hollister, California and Cirencester, England has been flying a Piper Malibu demonstrator, but anticipates flying a 10 to 20 passenger Dornier by 2024.  It would expand that to a 50-passenger craft by 2026.  H2Fly in Germany has been flying their Pipistrel-designed HY4 for several years and through six generations. The firm looks forward to taking incremental steps toward a 40-passenger regional airliner by 2030. ZeroAvia ZeroAvia reports on troubling trends in aviation’s contribution to greenhouse gases, but follows with a possible solution.  According to their web site, aviation accounts for over 12 percent …

Phinergy Aluminum/Air Batteries from India

Dean Sigler Announcements, Batteries, Electric Powerplants, Sustainable Aviation 1 Comment

Phinergy, an aluminum/air battery maker from Israel, is now partnering with Indian Oil Corporation.  Phinergy’s technology just received an award from the World Economic Forum as one of the 100 most promising Technology Pioneers for 2021.  Phinergy was chosen for, “Its innovative energy solutions which turn metals, such as aluminum and zinc, into a clean, sustainable and cost-effective means of storing, transporting and generating energy.” Why would Indian Oil Corp. (biggest oil outfit in the country) be attracted to Phinergy and its aluminum/air batteries?  Company R&D Director S.S.V. Ramakumar explains, “Lithium is scarce in the country and we started scouting for an element which is abundantly available as a natural resource.”  Unspoken, the idea that India has one of the …

Eviation Moves Alice’s Tail – to Washington

Israel’s Eviation has moved its manufacturing resources to Arlington, Washington, north of Seattle.  There, they are making an all-new version of Alice, changing its configuration from “V”-tailed to “T”-tailed and its power from tri-motor to bi-motor. The revised craft will be powered by two Magni650 power units, a package that includes a 640 kilowatt (850 shaft horsepower) motor, four magniDrive-100 inverter/motor control units, and “a closed-loop integrated thermal management system.” A New Alice Charles Alcock, reporting in FutureFlight.aero, says Eviation Aircraft confirms plans to make a first test flight of the redesigned craft by year’s end and have the new Alice certified and entering service in 2024. Obvious changes include a clean, high-aspect ratio wing and pylon-mounted motors flanking the …

Really Cool Battery News from NREL – Really

Dean Sigler Batteries, Sustainable Aviation Leave a Comment

Plaid Fire Car fires are scary.  Airplane fires are even more so, since you can’t just pull over and hop out.  Scientists at the National Renewable Energy Laboratory (NREL) and NASA, and in England and France may have come up with a way to stop electric car fires.  Owners of petrol-powered autos will have to continue to check for leaking flammable fluids, greasy engines, and sources of the 140,000 car fires in the US alone every year. There aren’t that many electric car fires, but they make the news.  One in particular, a brand new, low-mileage Tesla S Plaid, melted down after self-igniting.  Reportedly, the $130,000 car briefly trapped the owner inside. The Verge reports, “Luckily, the driver escaped alive. …

Aussies Complete Electric Aircraft World Endurance Record

Dean Sigler Announcements, Batteries, Electric Powerplants, Sustainable Aviation Leave a Comment

A three-pilot crew accompanied by a five-person, multi-vehicle support crew have set a world endurance record for electric flight.  The team traversed 1,350 kilometers (839 miles) over not-always-hospitable terrain and through not-always-welcoming weather.  Participants in the record attempt held up admirably, with few problems other than seemingly constant cross-wind landings and often uncooperative weather. Their flight made it onto Australia’s largest television network. The Airplane Eyre to There Managing Director Barrie Rogers explains the limitation of the aircraft and the effect this had on the flight.  “The Pipistrel Alpha Electro – dubbed the ‘Tesla of flying’ – currently has a flight time range of about 1 hour and cruising speed of 85 knots (157km/h) so we’ve had to very carefully …

Archer Debuts – Meet Its Maker

Dean Sigler Announcements, Electric Powerplants, Sky Taxis, Sustainable Aviation Leave a Comment

Immersive Introduction Amidst stage smoke and Hollywood-style dazzling lights, Archer Aviation “flew” its Maker into public view two weeks ago.  On an immersive cinema platform in a hangar in Hawthorne, California, Maker emerged amid all the pounding two drummers could produce.  It seemed to hover above the varied scenery over which it appeared and the on-stage and on-screen special effects were special indeed. The cynosure of the hoopla, however, was strangely static, even though its guiding lights were highly animated.  Co-founders and Co-CEOs Brett Adcock and Adam Goldstein performed flawlessly in promoting their creation, adding to the professionalism of the event.  Since the event was inside, and the crowd was allowed to come on stage under the rotor blades, it …

Aussies Attempt Electric Aircraft World Endurance Record

Dean Sigler Announcements, Batteries, Electric Powerplants, Sustainable Aviation 1 Comment

An Australian flying school and a flight planning software enterprise are in the middle of a series of flights that attempt to break an electric aircraft world endurance record. The cleverly-named Eyre to There Aviation announces that, “In partnership with platinum sponsor AvPlan EFB will aim to break a world endurance record for an electric aircraft with a 7-day, 18-stop flight around South Australia.” According to the organizers, “The proposed route will include flying across to the Lower Eyre Peninsula and inland back to Port Augusta for flight sectors around the Yorke Peninsula before arriving back in Adelaide, subject to aircraft performance and weather.” A 1,150 kilometer (714.6 mile) trek, the flight would “shatter the previous record of 750 km …
