Stephen Bridgewater made a quick announcement on ZeroAvia’s Twitter feed Thursday January 19 about a Dornier 228 that flew with a hydrogen-powered motor on its left wing.  ZeroAvia continues making the largest-yet H2 flights. ZeroAvia’s 19-seat Do228 flew today (from Kemble) at 13.35 UK time. It’s the largest hydrogen-electric powered aircraft yet to fly (hydrogen-electric engine on left wing and Honeywell TPE-331 on the right).  This comes a year after the firm started modifications to the twin-engine Dornier aircraft in both England and California, and a little over two years since it flew a Piper Malibu first on batteries, and then hydrogen.  Despite a crash landing that ended the Cranfield, England-based Malibu, ZeroAvia has stuck to its ambitious schedule.  Another …

Aircore: a Different Approach to Axial Flux

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

Aircore Mobility’s press release from the Consumer Electronics Show (CES) in Las Vegas headlines, “Sustainable, air core, axial flux, liquid cooled e-mobility motor achieves superior power density and efficiency to extend vehicle range for applications that drive, fly or sail” The company promotes its efficiency, high current density, and economy of manufacturing as prime factors in its success.  The printed circuit board (PCB) stator is claimed to be 10 times more reliable than a conventional stator, smaller, and lighter.  By replacing the iron core of a conventional motor with a PCB stator, “Mechanical losses are reduced, efficiency is increased and noise and vibration are significantly reduced.” Several stator/rotor combinations can be “stacked” with a single housing to allow greater power …

Aloha from Iolani and E-Hawk

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

Take a skillful design by an ultralight aircraft expert, add a small but dedicated group of high school students, a versatile advisor, and you end up with an electric aircraft that incorporates cutting edge innovation with a traditional airframe.  Iolani High School’s E-Hawk has been flying over Hawaii for the last few months, a reminder of how skilled and talented today’s high schoolers can be. Your editor did an article for Kitplanes magazine about their endeavors, with great help from the students and their advisor, Martin Emde.  The most surprising part of that story was how many electronic systems were essentially designed and fabricated by the students.  These included battery packs and some fairly sophisticated instrumentation. For instance, this motor …

Delft’s Maeve 01 Dreams Big

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

The Maeve 01 is the latest big dream from The Netherlands’ Delft Technical University – which  seems to be a resource-rich aeronautical community producing myriad flying machines.  The airplane comes with a novel recharging system, the Maeve ReCharge network – all to provide “Aviation for a generation that wants to travel, not pollute.” The eight motors spanning its high-aspect ratio wings could be replaced by six, but that depends on replacing the eight 1.2 megawatt (1609 hp.) motors with 1.5 megawatt (2,012 hp.) units.  This seems plausible, since Jeff Engler’s Wright Electric has recently tested a 2 megawatt (2,682 hp.)  motor and ZeroAvia plans on delivering 2 MW units to retrofit DeHavilland Dash 8s within the next few years.  One …

Pyka: All Red and Green and Unpiloted

Dean Sigler Electric Powerplants, Sustainable Aviation Leave a Comment

Appearing in a festive nighttime garb of red and green lights, Pyka’s aerial sprayer has been authorized by Costa Rica’s General Directorate of Civil Aviation (DGAC) to fly unpiloted aerial spraying missions at night. Pelican night spray missions are a go! Pyka recently secured the world’s first regulatory approval for nighttime aerial spray operations with a fixed-wing UAS. Read more about this industry breakthrough here – https://t.co/3SdOndk6pu#flypyka pic.twitter.com/c6aZv8vWhs — Pyka (@flypyka) November 2, 2022 The fully autonomous, all electric craft is now approved to spray large banana plantations – both day and night.  Since the aircraft flies well-defined routes daily, spraying crops at night should be no different. This first-ever regulatory approval to fly unmanned aerial spray missions at night …

Air New Zealand Plans for Zero Emissions

Air New Zealand has a five-part plan for reducing and even eliminating aviation emissions with some well-defined approaches and goals.  The airline hopes to achieve net zero by 2050, with demonstrable steps toward that starting now. Five Key Elements ANZ will rely on five key elements in its quest for zero-emission flight.  They are already involved in producing sustainable aviation fuel (SAF), partnering with makers of zero emission aircraft technologies, renewing their fleet, reducing carbon emissions through improved flight and ground operations, and removing carbon using best known techniques.  You can read the full sustainability report here. Producing SAF Sustainable aviation fuel (SAF), explains Air New Zealand, “Is made from a variety of sustainable resources other than crude oil, such …

Electric Air Racing News

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

Electric Air Racing is a modern take on an age-old idea.  Ever since people tamed horses, the idea of comparing their speeds became important.  Boats, cars, and aircraft followed the same path.  As with horses, the idea that “racing improves the breed” held sway.  Now, one Australian company and a major aeronautical organization hope to make air racing a path to the future. Alauda Aeronautics Matt Pearson founded the Airspeeder  racing program with the credo, “Competition accelerates progress.”  Toward that end, he partnered with Alauda, an Australian firm, to develop a group of high-performance aerial racers.  Looking somewhat like the vehicles flown by Luke Skywalker in the Star Wars films, the “flying cars” certainly evoke a performance image. The team …

Keeping Battery Fires at Bay

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

Keeping battery fires at bay is a constant irritant, if not downright hazard, in the electric vehicle world.  Battery fires are particularly scary in aircraft, where help may be 35,000 feet below.  Three different solutions have been introduced by industry and scholars, though, and may reduce, or even prevent such unfortunate occurrences.  That the three solutions were featured in the same day’s postings of GreenCarCongress.com is a bit astonishing, but heartening.  The three contenders appear below. The Honeywell and Nexceris Sniff Test Honeywell has a strategic alliance with Nexceris, developer of the Li-ion Tamer (a horrible pun, as you may have noticed) lithium-ion gas detection solutions.  Instead of waiting for things to heat up, as happens in thermal runaways,  the …

H3 Dynamics and Its Hydrogen-Electric Nacelle

Dean Sigler Announcements, Electric Powerplants, Fuel Cells, hydrogen, Hydrogen Fuel, Sustainable Aviation Leave a Comment

H3 Dynamics (formerly HES – Horizon Energy Systems) has flown a small example of its hydrogen-electric nacelle that could power many craft now in the concept phase.  H3 headlines its web page with the words, “Dreaming Big,” followed by the premise, “The future of aviation is hydrogen-electric, autonomous, and digital.”  Their press release declares, “The future of hydrogen aviation powered by H3 Dynamics’ distributed hydrogen propulsion nacelles has taken flight for the very first time in France.” Hydrogen could be a dream fuel, clean burning and leaving only a little water vapor in its wake.  It has a few drawbacks, though.  H2 takes up four times the space of gasoline or kerosene for a roughly equivalent amount of energy.  In something …

Jekta’s amphibious commuter liner made its debut at the Abu Dhabi Air Expo 2022.  The 10-motor amphibious, 19-passsenger craft could become a familiar sight at coastal landings around the world based on initial interest. Deena Kamel, reporting for The National News, revealed PHA-ZE 100, short for Passenger Hydro Aircraft Zero Emissions, is now in its design stage, “with a prototype scheduled for 2026 before entry into market by 2028,” according to Jekta CEO George Alafinov. Intended to transport people in mega-cities and coastal areas “sustainably and affordably,” according to the article, the 19-passenger is a response to a “world population with an appetite to travel safely, cheaply and ecologically.” Mr. Alafinov makes the case for amphibious craft.  “The solution is …
