Itching to test your electric airplane’s cross-country capabilities?  A new Pulitzer Electric Air Race of over 1,000 nautical miles (1,150.78 statute miles to be exact) between Nebraska and North Carolina will show who has the fastest electric flying machine. Jim Moore, reporting for the Aircraft Owners and Pilots Association (AOPA), shows the connection between the original Pulitzer Trophy and today’s electric competition.  “Five of the first six pilots to have their names engraved on the Pulitzer Trophy were military airmen clocked around a closed course at speeds starting at 157 mph in 1920, up to a blistering 248 mph by 1925. The trophy was created to inspire innovation, and particularly faster airplanes. That vintage trophy housed at the Smithsonian National Air and Space Museum will be engraved with its first new name in 97 years in 2022, following completion of a 1,000-nautical-mile cross-country race by up to 25 electric aircraft.” Ralph Pulitzer was son of Joseph Pulitzer, whose prizes for …

Joby Aero Inc. has displayed its ultra-quiet operation, flown a promised distance and become an investment favorite in the last few months. Now it’s headed to Washington, D. C. to consolidate relations with law- and opinion makers. Quietude As a follow-up to its recent demonstration of quietude on Public Broadcasting’s “Great Electric Airplane Race,” Joby staged a head-to-head test of its near silent operation against other aircraft.  Note the perceived noise and the aural signature as each craft passes overhead. Going the Distance One thing prominent in Joby’s on-line presence is their promise that their electric air taxi will be able to travel 150 miles on a single charge – including a vertical takeoff and landing. Flown from the ground by Chief Test Pilot Justin Paines, the machine, “…Took off vertically before transitioning to forward flight and completing 11 laps of a predefined circuit. After more than 1 hour and 17 minutes in the air, the aircraft landed vertically, having …

The Layered Look in 1000x Solar Cells

Dean Sigler Announcements, Solar Power, Sustainable Aviation Leave a Comment

We hear a lot about 10X batteries, but 1000X solar cells?  Layering up may be stylish and even practical in the fashion world, and in solar cells may be a chance to unite otherwise dissimilar materials with otherwise limited light-to-electric conversion capabilities.   That strategy produced solar cells with 1000x that.  That’s what researchers at Martin Luther University Halle-Wittenberg (MLU) found when they created crystalline layers of layers of barium titanate (a mixed oxide of barium and titanium), strontium titanate and calcium titanate which they alternately placed on top of one another. Researchers found high increases in responses from the layered oxides because of higher permittivity – electrons able to flow more freely. The team’s paper, “Strongly enhanced and tunable photovoltaic effect in ferroelectric-paraelectric superlattices,” appears in the June 2 issue of the journal Science Advances. A Titanate Sandwich Barium titanate (BaTiO3 or BTO) is a “common ferroelectric material” used to manufacture electronic components such as capacitors.  It is, “a popular …

Joseph Oldham Beams an American Record

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

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 a field that should have shown greater progress that it has.  Batteries are not that much improved in some respects. Recent flights in Australia, Europe, and America required a mobile infrastructure to charge those batteries.  Cars, trucks and airplanes carried …

Take Heart!  United We Fly!

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

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 market, the possibilities are expansive, with many small airlines flying short routes ready for such a craft. Heart sees the 19-seat market as promising, since few 19-seat commuter liners exist anymore.  Part of that is economic, with small turboprops being …

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 most polluted airsheds in the world, means increasing pressure on Big Oil to redeem itself.  Reuters reports, “India was home to 35 of the world’s 50 most polluted cities, according to IQAir’s 2020 World Air Quality Report, which gathered data …

Eviation Moves Alice’s Tail – to Washington

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

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 “T” tail.  According to Alcock’s report, a company spokeswoman explained, “We moved from a V-tail to a T-tail to optimize performance and handling and make it easy and reliable for pilots to seamlessly transition to flying the aircraft.” Two crew …

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 plan each stop and build in contingencies for weather such as strong head winds.” The craft itself shows the characteristics that make it a good trainer – but probably not one’s choice for a world endurance record.  The 10.5-meter (34.5 …

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 was probably prudent to have the motors raised and inactive. Less static in this Computer Fluid Dynamics (CFD) rendering, the Maker displays the flow around its 12 rotors in vertical flight.  Since battery tests are underway, perhaps soon we will …

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 (466 miles) flown in September 2020 in [Switzerland and] Germany.”  The Europeans needed 11 stops for recharging on their trip, so the 18 planned by the Australians is comparable for the planned distance. Aviation vlogger Stefan Drury hopped a ride …
