Teofilo Leite has been refining a beautiful twin-motor glider for the last decade.  Apparently he’s moving on to a five-seat, four-motor, dual-propeller beauty that is set to take on the world.  The Electron 5 looks a great deal like a larger Electron 2, which has been flying in various configurations for the last decade. Electron Aviation, with representatives in The Netherlands and Australia states, “Our Electron 2, a two-seater battery-electric aircraft (Teofilo’s earlier design), is the flying proof that our energy efficient aircraft designs deliver outstanding performance. Whilst being well within inside the 600-kilogram (1,320 pound) ultralight microlight [regulations], it achieves 3 hours flying time during which it can cover 300 kilometers (186 miles).”  Electron 2 flies its pilot and passenger on 7.5 kilowatt hours per hour of flight.  Its three-hour endurance would mean a battery of at least 22.5 kilowatt-hours. Continued improvement to the Electron 2 required “30,000 design and engineering hours and several re-designs.”  The latest iteration “has …

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 …

A L.E.A.P. Forward for Electro.Aero

Heady Ambitions Joshua Portlock, Co-founder, Director and Chief Technology Officer for Electro.Aero in Perth, Australia, has a heady set of ambitions.  He and Rob Belaga presented a simple electric vertical takeoff and landing machine, FlyKart, at two different symposia in northern California two years ago, and presented a refined version for the Boeing GoFly competition shortly thereafter.  They’ve made it to the finals of the $2,000,000 contest and will be in the February, 2020 flyoff. In the meantime, he’s started a flight training program using Pipistrel’s Alpha Electro trainer, and is partnering with an almost bewildering  set of industry, government and academic leaders, including Ampaire, Bye Aerospace, E/S/Aero, NASA, Pipistrel, University of Western Australia, and Zero Emissions Vehicles Australia.  Joshua gives a rundown in his down-under TED Talk. Working with ducted fan systems leads to a redesign of a Diamond DA-40 that ditches the internal combustion engine in the nose for a battery pack.  One ducted fan behind and on …

Go Fly’s Phase II Winners

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

One complaint frequently heard is that aviation doesn’t necessarily encourage participation by women, despite historical examples from Harriet Quimby to Jeanna Yeager.   GoFly is a competition thought up by Gwen Lighter, a lawyer with degrees from Brown (summa cum laude) and Harvard (cum laude) Universities. It has a $2 million prize package backed by Boeing and others.  Ms. Lighter describes her brainchild as follows: “The $2 million GoFly competition encourages mad scientists and daredevils to come as close as possible to Star Wars’s light cycles, James Bond’s jetpack, Marty McFly’s hoverboard, or any other flying dream.” Five Phase 2 winners exemplify the open rule-book approach around which the contest is organized.  Lighter explained it two years ago in an NPR interview.  “What the device looks like and how it works is up to the innovators.  We do not mandate that it’s something you get into like a car, or something that you strap on your back, or something that you …

Book Your Perth Alpha Electro Flights for the Early Morning

Two Things That May Not Seem Related at First Recent news that Penrith, Australia was the hottest place on earth was underlined by videos of melting highways.  Penrith, a suburb of Sydney, reached 47.3° C (117° F), enough to turn asphalt into a sticky mess and force drivers onto less gummy shoulders. Although over 2,400 miles away, Perth, home to Joshua Portlock’s Electro.Aero flying service, is at roughly the same latitude, and experienced near-record heat this month.  Possibly, that accounts for the all-caps caution for prospective flyers: “WE RECOMMEND EARLY MORNING FLIGHTS IN SUMMER FOR THE SMOOTHEST CONDITIONS.” Joshua’s company took delivery of a Pipistrel Alpha Electro, and flew it on January 2, a first in Australian aviation.  He and his team are offering two-hour instructional flights in the new aircraft for $220 AUD (about $172 USD).  This opportunity to take lessons in an electric airplane will include the benefits of quiet, smooth flight.  But heat brings on turbulence, and …
