New Atlas (formerly Gizmag) alerted your editor to this web site, which in turn features over a score of YouTube videos on this fascinating project in Sweden.  Axel Borg has created, as promised by the web site, an Amazing DIY Project, flying around a hilly woodland on the power of 76 electric motors. Undaunted by Fuel Fumes or Crashes More amazing, perhaps, he tried this configuration a year ago with eight internal combustion engines (extremely noisy), but managed to crash that.  Resisting the fear that would instill in queasier souls (your editor, for instance), Axel made four tubular rings, within each of which is mounted a set of 19 motors.  The four rings surround the pilot’s seat, under which are …

ONERA’s AMPERE Flies on Distributed Electric Thrust

Dean Sigler Electric Aircraft Components, Electric Powerplants, Fuel Cells, Sustainable Aviation 0 Comments

ONERA’s mission statement for its AMPERE (Avion à Motorisation réPartie Électrique de Recherche Expérimentale) electric aircraft is fairly straightforward.  “AMPERE is a demonstrator of a regional airplane with electric propulsion distributed, allowing to transport from 4 to 6 people over 500 [kilometers – 310 miles] in 2 hours.  The objective of the AMPERE project is to bring to maturity the technology of distributed electric propulsion in order to transfer it to the industry.”  ONERA, the Office National d’Etudes et de Recherches Aérospatiales (National Office for the Study and Research of Aerospace) is the French equivalent of NASA. ONERA showed a one-fifth-scale model of AMPERE at the Paris Air Show last week, with spokesman and designer Jean Hermetz holding forth on …

Airspace X MOBI Wants toTake Back Our Lives

Dean Sigler Announcements, Electric Powerplants, Sustainable Aviation 0 Comments

Airspace X decries the thought that “Traffic is taking over our lives.”  It lists three concerns: the 42 hours urban commuters sit in traffic per year; the 1.9 billion gallons of fuel wasted due to road congestion; and the $1,400 wasted per driver per year due to traffic.  Its solution, an electrically-powered four-seat commuter vehicle called MOBI.  The e-VTOL (electric vertical takeoff and landing) machine, introduced at the Uber Elevate Summit on April 27, lays claim to being able to fly its passenger at rates equal to an Uber Black ride. According to NBC News, Uber Black “town car” style trips are usually longer than “standard” rides, in a shortlist of approved vehicles – the Audi Q7, BMW X5, Cadillac …

Volocopter, Dubai Sign Autonomous Air Taxi Agreement

Dean Sigler Announcements, Batteries, Electric Powerplants, Sustainable Aviation 0 Comments

Dubai, already having penned a similar agreement with China’s eHang, will start test runs of autonomous air taxis in 2017 with the Volocopter. Volocopter’s Eventful Year Volocopter has had an eventful year, introducing its latest model, the 2X, at this year’s Friedrichshafen Aero E-Flight Expo and opening its new corporate headquarters.  Now, it looks forward to demonstrating its craft in regular service.  e-Volo writes, “Our vision becomes reality: Dubai’s government “Roads and Transport Authority” (RTA) has signed an agreement with us regarding the regular test mode of Autonomous Air Taxis (AAT) in the emirate. The test will start in the fourth quarter of 2017, and the project has been scheduled to run for five years.” The Volocopter 2X, according to …

EViation Electric Aircraft: Demanding Disruption

Aviation Week reports from the Paris Air Show on a “disruptive” entry in electric aviation.  Eviation, founded by Omer Bar Yohai, is primed to deliver a change in transportation as we know it.  Yohai says, “The dominant solutions available today are deeply flawed and demand disruption.” The company’s promotional video only hints at the company’s intentions.  Their vision statement on their web site, though, indicates a skyward aspiration: “Making electric aviation the fast, competitive and clean answer to on-demand mobility of people and goods.”  Aviation Week’s Noam Eshel quotes Bar Yohai as saying, “We design, test and build the tools that will enable future of regional transit by air, changing consumers’ perception of both distance and time.  Five years from …

Long Hours of Droning On

Several different organizations are trying different ways to keep unmanned aerial vehicles, UAVs, up longer.  We’ll look at three recent efforts in long-endurance missions, each with a unique technological approach. Wirth Research – Hydrogen Fuel Cell Wirth Research is now constructing a new tilt rotor, Vertical Take Off and Landing (VTOL), hydrogen fuel cell powered, advanced terrain-mapping drone.  Carrying a payload of sensors and onboard data processing capabilities, the vehicle will be powered by a complete H2 storage, control and power system provided by HES of Singapore, a specialist in ultra-light hydrogen fuel cells. The Wirth machine’s missions range from precision agriculture, to pipeline and cable inspection for utilities, surveillance and other security-related tasks, through to detection and monitoring support …

Traveler Hybrid – An Electrifying Transformation

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

Urs Villiger, with the assistance of, “A network of aviation specialists…under the leadership of Calin Gologan CFD Consultants,” crafted a sleek four-seater, the Traveler TR230.  That airplane, originally flown with an internal combustion engine, has apparently been recrafted as a hybrid craft.  Gologan, along with Dr. Volker Kassera, did the majority of the aircraft’s design. First flown on December 4, 2015, the gas-powered Traveler was very much a fixed landing gear airplane, replete with wheel pants.  The large canister under the cowling and forward part of the fuselage is a so-called “Swiss muffler,” a great deal like a “glass-pack” used by American hot-rodders in the 1950’s.  It was developed by experimenters in Switzerland to comply with noise regulations.  The major …

Surefly – A Pickup and a Pick-Me-Up

Dean Sigler Electric Powerplants, Hybrid Aircraft, Sustainable Aviation 0 Comments

We’re experiencing a myriad of multi-rotors lately, mostly in the vertical lift on demand, sky-taxi  category.  Workhorse, a company specializing in electric vehicles, has introduced the Surefly, an eight-rotor, hybrid-powered two-seater with actual pilots in mind.  Workhorse will reveal the aircraft at the Paris Airshow on July 19, possibly filling in the blanks for the internal-combustion engine and electric motors on the machine. The company started with an award-winning conversion of a Pontiac Sky and has leapfrogged into the creation of unique electric vehicles.  These include not only Surefly, but  a hybrid pickup truck, a hybrid medium-duty step van useful for local deliveries, and Horsefly – an eight-rotor drone capable of delivering 10-pound packages.  Horsefly is launched from the step …

Another Combined Motor-Controller System

Dean Sigler Electric Powerplants, Sustainable Aviation 1 Comment

Compact Dynamics, a German electronics firm associated with MAHEPA, the green aviation consortium, has developed two types of electric motor-controller combinations adaptable to aeronautical use.  Their Dynax® Transversal flow machines and Dynadyn® Radial flux drives integrate power electronics with the motor. Their Dynax MGi25-48, one of two lower-power motor-controller combination, is rated at 25 kilowatts (33.5 horsepower) maximum power at 58 Volts, and 20 kW continuous output.  The small motor can generate an impressive 75 Newton-meters (58.3 foot pounds) of torque from its 14 kilogram (30.8 pound) heft.  Even with its controller mounted atop, the full motor package is only 318 millimeters (12.5 inches) high, and 233 mm (9.17 inches) deep.  The motor itself is only 107 mm (4.2 inches) …

A Swan among the Ultralights

Dean Sigler Electric Aircraft Materials, Electric Powerplants, Sustainable Aviation, Uncategorized 0 Comments

At this year’s Aero Friedrichshafen, Modern Wings showed off their Swan Ultralight, a nicely packaged machine that can fly on either fossil fuels or electricity.  Of course, we’ll feature the electric version here. The Swan E115-22 is an electrically-powered airplane of 115 kilograms (253 pounds) empty weight powered by a 22-horsepower motor.  That empty weight puts it solidly into U. S. FAR Part 103 territory and SSDR (single-seat deregulated) requirements in Great Britain, and a 120 kilogram (264 pound) version complies with Regulation 120 in Germany.  Maximum takeoff weight is 300 kilograms (660 pounds), heavier than the 524 pounds Part 103 allows, and possible legal depending on how local FAA inspectors view batteries as part of empty or total weight. …
