Electra Aero Goldfinch on Grass

Anyone astonished at the brilliant short-field performance of the Electra Aero Goldfinch from a paved runway a few weeks ago will be equally surprised at its agility from a grass runway.  This eSTOL (electric Short Take Off and Landing) airplane seems to perform well even from unimproved runways. In its own press release, the company reports on the small craft’s ability to take off and land on “austere fields smaller than 300 feet that are minimally prepared.”  Citing its work with “Agile Combat Employment and expeditionary missions” for the military, explains the economy of such craft.  “Small, affordable, runway-independent eSTOL aircraft could also alleviate demand on larger, few-in-number, high performance fixed wing and rotorcraft platforms in a contested logistics environment.” That’s a 32-degree angle of climb, by the way, according to the AOPA Pilot report. More Usable Runways Aircraft like the Goldfinch and its larger commuter liner coming from Electra would open up otherwise unusable “airports” which might be nothing …

Electra Rolls Out a Full-size Demonstrator

Dean Sigler Announcements, Batteries, Hybrid Aircraft, Sky Taxis, Sustainable Aviation Leave a Comment

Starting small, Electra Aero has rolled out a two-seat demonstrator of its multi-motor, blown-lift technology.  Bright yellow, the EL-2 “Goldfinch” celebrates “the beloved, nimble American Goldfinch bird indigenous to North America,” according to the company.  Its full-scale production aircraft will carry nine. John S. Langford, Founder and CEO of Electra.aero explains, “In the three years since we founded Electra, we’ve designed our eSTOL aircraft, validated our blown lift technology with a sub-scale demonstrator, and run a fully integrated test of our 150-kilowatt hybrid-electric generator at full scale.  Now we’re ready to test the entire system with this technology demonstrator aircraft. We can’t wait to fly this plane and show the world what our eSTOL aircraft can do.” Chris Courtin, Chief Engineer on the technology demonstrator project, explains the ambitious aircraft, a two-seat version of which will fly this year. Electra notes its “proprietary blown lift technology uses eight motors to provide additional wing lift, and hybrid-electric power that provides internal …

Following the Money to Green Flight

The path to green flight is paved with money.  In our transactional world, good ideas are sometimes rewarded with filthy lucre, even if those ideas are intended to clean up a besmirched world.  Several examples of clean aviation attracting solid investments follow, along with some stumbling on unexpected obstacles. Jetson ONE For a flying machine lighter than most of its prospective pilots, the Jetson ONE has attracted a host of followers, including the host of a late-night chat show.   Besides receiving 3,000 purchase requests in two months the firm has sold its initial production runs for 2022 and 2023. At $92,000 a unit, 100 craft in the first year would net $9.2 million, enough to finance the simple assembly and fabrication of the machines.  A $22,000 deposit would discourage idle gawkers, although Internet views exceed 14 million.  Keeping it simple allows reasonable progress to the next level.

Electra.Aero Acquires Airflow

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

Too Similar Not to Have Joined Forces The PRNewswire.com press release lauds the acquisition of Airflow.aero by Electra.aero: “Hybrid-Electric Blown-Lift eSTOL Plane Developer Electra Acquires Airflow to Create a Leader in Advanced Air Mobility.”  The two companies have been developing similar multi-motor, blown-lift aircraft for the past few years.  Electra’s has eight motors distributed across its wingspan, Airflow’s has 10. They both use large multi-element flaps to divert propeller thrust downwards, enabling extremely short takeoffs and landings. A Great Idea, but Better with Electric Power This is not a new concept, having been demonstrated in the 1960s by French manufacturer Breguet and American McDonnell.  The 188 was a demonstrator that didn’t pick up any orders in either country.  The narrator explains propeller control was a mechanical-hydraulic process and no electronics were involved.  The complex system might have been a maintenance challenge airlines were unwilling to take on.  Electra.aero’s hybrid-electric approach might be the answer to simpler, reliable propulsion, essential for …

Electra Attracts Customers, Investors and Landing Sites

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

Electra Aero has found worldwide interest in its electric ultra-short take-off and landing airplane, an eight-motor craft capable of taking off and landing across most jet-size runways. Producing such an aircraft takes great design, appropriately-designed landing sites, a well-integrated infrastructure, and financial backing for the total package. Electra Aero for the Design Powered by a hybrid generator driving four electric motors, Electra Aero’s aircraft uses “blown lift” to take off over very short distances – less than 150 feet, according to the company. Ben Marchionna, director of technology and innovation at Electra Aero, explains, “eVTOLs use electric propulsion to take off and land vertically – many of these concepts then transition from vertical flight to forward flight with a wing providing the lift once in cruise… Vertical flight requires significantly more power, resulting in an enormous payload, range, and cost penalty. eSTOLs use electric propulsion and an aerodynamic technique called blown lift to takeoff over distances as short as 100 …

eCSTOL: Longer Range Commutes on Less Power

Dean Sigler Diesel Powerplants, Electric Powerplants, Hybrid Aircraft, SAS, Sky Taxis, Sustainable Aviation Leave a Comment

Competition is growing in the electric Vertical Take Off and Landing market, with 407 potential builders listed in eVTOL News.  Vertical flight takes power, though, and with available batteries limiting range, most such vehicles can make only short hops.  Alternatives that allow speedier, longer flights, in the form of electric Conventional Short Take Off and Landing (eCSTOL) aircraft are in development. Such craft offer the benefit of requiring less power for takeoffs and climbs, being more aeronautically-based than power-based.  Airflow, for instance, claims operating costs for their eCTSOL craft is one-third that of an eVTOL or helicopter. We will look at three eCSTOL craft that seem to making headway at this time.  The infrastructure (in two cases below) to support their flight may already exist. Airflow Curt Epstein, writing in Future Flight, under the headline, “Infrastructure Needs for eSTOL and eVTOL Aircraft May be Closer than Imagined,” notes the “intense study” being undertaken.  Speaking at the Vertical Flight Society’s  Electric …

John Langford’s New Direction

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

John Langford has been a leading exponent of new directions in aeronautical technology.  From his work as project manager with MIT’s human-powered Daedalus project to his executive leadership with Aurora Technologies, he has crafted electric, autonomous, and downright astonishing vehicles.   The following video is long, but insightful and exciting.   We see Langford in several early scenes. Having seen Daedalus conquer the Sea of Crete like the mythical first airman, Langford spread his reach into ever more technologically complex problems.  His resume is deceptively short, since he’s held only two jobs since leaving college.  His LinkedIn bio is brief, but telling. “John Langford is the founder and CEO of Electra.aero, a startup developing hybrid electric aircraft for regional mobility. He founded Aurora Flight Sciences in 1989 and served as Chairman and CEO through 2019. He is a member of the National Academy of Engineering and serves as President of the American Institute of Aeronautics and Astronautics (AIAA).” The video gives a …
