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

Sonex and Gabriel DeVault have partnered to create an electric kitplane, marketing components for a different type of powerplant.  Sonex has been in the kitplane business since 1998 (having built from a decade’s-old earlier company) and Gabriel DeVault has been working with the electrification of aircraft for a decade.  Combining their expertise, we have a kit built path toward an inexpensive electric kitplane. Gabriel commutes a lot by air, traversing the globe between his home in Watsonville, California and Cranfield, England for work on Zero Avia’s electrification of Dornier 228s – one in each country.  He flies between Watsonville and Hollister, California in his Zero Motorcycle powered eXenos, a kit built product from Sonex Aircraft in Oshkosh, Wisconsin.  Before that, he flew a Mark Beierle eGull powered with a Zero motor.  Gabriel was instrumental in the design and manufacturing of that motor, making him a bona fide expert on the powerplant. His experience with the eXenos has led Sonex to …

Influit Going Commercial

Dean Sigler Batteries, Electric Aircraft Materials, Electric Powerplants, Sustainable Aviation, Uncategorized Leave a Comment

Influit Energy, a spinoff from Illinois Institute of Technology, is going commercial in a big way.  They claim to have developed a “rechargeable electrofuel – a non-flammable, fast-refueling liquid flow battery that already carries 23 percent more energy than lithium batteries, at half the cost.”  Reporting by Loz Blain in New Atlas.com notes the company plans “to commercialize its ultra-high density liquid batteries.” The firm’s “nanoelectrofuel,” a motor-oil consistency liquid, would refuel a vehicle with a special four-point nozzle.  The process would allow users to be on the road or in the air in a few minutes, rather than a few hours as with batteries.  Like a battery, the liquid comes with a positive and negative component – two liquids – an anolyte and a catholyte instead of a more solid anode and cathode.  The system requires four tanks – one each for incoming positive and negative liquids and one each for spent liquids that return to the supply source …

Two very different electric aircraft found their ways to AirVenture 2022 in Oshkosh, Wisconsin last week. By eGull from West Virginia 72-year-old Jean Preckel of Bruceton Mills, West Virginia flew her home-built Beierle eGull from her home town to the Experimental Aircraft Association gathering accompanied in a chase car driven by Mark Beierle himself. She is a craftswoman of note, having built fine-arts level models of boats from 1983 until she retired a few years ago.  In 2019, she built and launched a lovely row boat, which displayed her great workmanship and rowing ability. The regional TimesLeader online news outlet reported that having, “…biked biked across the country, along the Appalachian Trail, traveled across Europe working odd jobs, [she] was looking for something new. She eventually came across electric planes.”  This led her to Mark Beierle, who fields a unique builder assistance program. Mark probably supplied builder assistance to Jean, and acted as her ground crew on their epic trip …

Elektra Solar Trainer Unveiled 

Dean Sigler Announcements, Batteries, Electric Aircraft Components, Electric Powerplants, Solar Power, Sustainable Aviation Leave a Comment

Elektra Solar introduced its Trainer, a new two-seat craft, at this year’s Aero Expo.  As reported here last year, the airplane features side-by-side seating to facilitate training, doubtless enhanced by the low noise level – 50 dB, according to the company.  Based on German ultralight standard LTF-UL 2020.  Compared to a “moderate rainfall noise,” the low sound level allows operation in noise protected areas and should enable easy communication between student and instructor. Safety and Performance With safety in mind, Calin Gologan, the plane’s designer, chose Geiger Engineering’s HPD50D dual motor.  Putting out 50 kilowatts continuously or 70 kW peak power, the 16 kilogram (37.3 pound) unit can run on either or both rotors.  Both independently controlled motors drive a 1.75 meter (5.74 foot) controllable-pitch propeller at up to 2,600 rpm.  If one motor fails, the remaining unit can maintain a climb rate of 1.5 meters per second (295 feet per minute).  With both motors running, the craft can climb …

Drexel’s Accidental Sulfur Battery Discovery

Dean Sigler Announcements, Batteries, Electric Aircraft Materials, Sustainable Aviation Leave a Comment

Chained to Supplies? A sulfur battery uses an abundant, energy-dense material not subject to the limitations of many supply chains like those for lithium, cobalt, and nickel – all necessary for batteries as they are now constructed.  William Lockett, writing for freethink.com, highlights the potential magnitude of a discovery by Drexel University researchers. “Every now and then, revolutionary technology seems to spontaneously appear out of thin air and change our world. Dynamite, penicillin, X-ray machines, and even microwaves are all examples of such revolutionary accidental discoveries. “Well, this year we may have had yet another. However, this time it is set not only to revolutionize the way we live, but potentially save our planet from looming climate change by unlocking an elusive technology: lithium-sulfur batteries.” Drexel’s Accidental Discovery Drexel University may have come up an answer to that need, even big enough to justify Lockett’s enthusiasm.  Vibha Kalra, PhD. leads the school’s Department of Chemical and Biological Engineering, and reports …

Beta’s Alia Makes a Highly-charged Trip

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

Beta Technologies has taken an all or nothing approach from its beginning, designing charging stations and flight crew centers to complement its aerial vehicles.  Last month, Beta got a chance to show at least part of its cross-country ambitions. A Six-State Outing From May 23 to May 24, Betas Alia 250 eVTOL (electric Vertical Take Off and Landing) aircraft made one of the longest cross-country flights at that time for such a vehicle.   Alia did not take advantage of its vertical capabilities, relying instead on conventional runway-borne takeoffs and landings. The total flight from Plattsburgh to Bentonville covered 1,355 miles (2,181 kilometers) and took almost 12 hours – about like a similar flight in a Cessna 172. Charging Stations Beta has planned well-thought-out charging stations to complement the craft and crews.  Each 480-Volt station has a landing platform roof, crew quarters with sleeping and bath accommodations and, of course, a charger.  The current route included stops where the Beta charging …

Lifetime Batteries?

What if your new electric car came with a steel-clad warranty on its lifetime batteries?  Your editor’s father would have asked, “Whose lifetime?” but researchers at Dalhousie University suggest that might become a reality. lIn a paper in the Journal of The Electrochemical Society, “Li[Ni0.5Mn0.3Co0.2]O2 as a Superior Alternative to LiFePO4 for Long-Lived Low Voltage Li-Ion Cells,” Jeff Dahn’s research team explains a different approach to battery longevity.  The chemistry is similar to that used in millions of cells, but lowers the amount of carbon to operate at 3.8 Volts rather than 4.2 Volts.  These lower output cells, “Have an energy density that exceeds that of the LFP cells and a cycle-life that greatly exceeds that of the LFP cells at 40 °C, 55 °C and 70 °C. Excellent lifetime at high temperature is demonstrated with electrolytes that contain lithium bis(fluorosulfonyl)imide (LiFSI) salt, well beyond those provided by conventional LiPF6 electrolytes.” NMC532 refers to the ratios of nickel, manganese, and …

Three Light Electric Motorgliders

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

Light electric motorgliders work well in the real world.  They’re light, compact, and easily transported to a flying site or back home.  Their small battery packs can be charged at home (under safe conditions) and provide enough duration to get the small machines to altitude, where they can explore thermals and ridge lift.  Because they are small, they require less materials and are often less expensive than standard-class or larger sailplanes.  Because they can self launch, they spare the cost of towplanes and possible chase crews. Economics aside, these craft provide fun flying and fairly untroubled ownership. Birdy We’ve reported on Birdy before.  It’s a 120-kilogram airplane, a class that in Europe allows pilots with a sport license and no medical to fly.  Its Eck-Geiger motor allows self-launching and one or two 3.6 kilowatt-hour batteries enable driven flight up to 200 kilometers (124 miles). Shown at Aero 2022, Birdy showed its clever cooling system for its mid-ship mounted motor.  Its …

Piaggio’s Electric or Hydrogen Concept – Not Yet

Clearing the Fumes Charles Alcock reports for FutureFlight.com, and shares that, “Piaggio Aerospace is laying plans for a possible hydrogen-electric business aircraft featuring a completely new airframe.”  Piaggio is probably better know for the Vespa scooters that dot Italian boulevards,  Those have even gone electric, a saving grace for pedestrians along the strada who won’t have to inhale two-stroke engine fumes. Piaggio makes two versions of its Elettrica – 45 Km/H (28 mph) and 70 Km/H (43.5 mph).  Both powered by a four kilowatt (5.36 horsepower) motor, driven by a 48 Volt, 25 kilogram (55 pound) battery.  The speed difference seems to be a software/firmware setting that limits the slower scooter to a regulated speed. It would seem almost natural, then, that the company would electrify its next aircraft.  It’s not that simple, according to Piaggio’s Chief Technology Officer. Piaggio Aerospace Piaggio is an industrial giant, established in 1884 and building aircraft since 1915.  The firm built single-, twin-, three-, and …
