 The Starling Jet now joins electric or hybrid flying commuter craft from sources all over the world. A Middle-East backed, London-based project, the Starling Jet is swoopy and high-winged, and comes in three sizes with different missions. The Commuter Craft Trifecta Time, a most precious commodity, is the major selling point for most of these sky taxis.  Saving an executive’s schedule enhances productivity, whether it’s whisking a CEO over the traffic jams in Dallas or Dubai.  For many similar machines, the impetus is to democratize the flight experience, offering many an Uber-like experience at Uber-like prices.  Samad Aerospace, creator the Starlings, is looking toward a more exclusive market. All such craft promise the convenience of point-to-point transportation, foregoing intermediate shuttle …

Schleicher’s Sustainable Flight for Two

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

Alexander Schleicher Segelflugzeugbau (sailplane maker) has been crafting high-performance soaring craft since its inception in 1927.  Their latest creation, a two-seat, 20-meter (65.6 feet) span motorsegler, the ASG32 El, includes a 25 kilowatt synchronous motor driving a Schleicher-designed 1.55 meter (5 feet) retractable propeller.   The motor is a “home help” device, a sustainer motor to keep the ASG 32 El aloft once it is launched by a winch or by being pulled by a towplane.  The motor does not allow for self-launching.  Its low power, coupled with the airplane’s clean design, does enable a 1.3 meter-per-second (255 feet per minute) rate of climb.  The aircraft’s battery is sufficient for 20 minutes of all-out power or 100 kilometers (62 miles) …

MAGiCALL Motor/Controller Vies for Simplicity, Lightness

Dean Sigler Electric Powerplants, Sky Taxis, Sustainable Aviation 1 Comment

MAGiCALL, a California-based firm whose slogan, “Innovative Magnetics to Power Your Products,” covers everything from aircraft to medical applications, has introduced a combined MAGiDRIVE™ integrated motor and controller line of products.  These are of particular interest for electric aircraft designers, since the company has been picked to supply motors to the Airbus A3 Vahana project. Whatever else they may accomplish, the many multi-rotor sky taxis will create a demand for a great number of motors, controllers, and battery packs.  16 on every Volocopter, eight to 16 on every Ehang, and eight on every Vahana will promote mass production, perhaps leading to a Model T moment where such technology becomes universally affordable. What Ford did for automobiles, most of the current …

Ehang Flies One and Two Passengers in Surprising Flight Demonstrations

An Executive Perk Unlike Any Other Chinese firm Ehang staged a demonstration of great confidence in its 184 (one passenger, eight motors/rotors, and four arms) autonomous flight vehicle.  The CEO and all executive members of the firm, and Guangzhou government officials got rides, with many giving thumbs-up signs during their trips. Hu Huazhi, Founder and CEO of Ehang, fills us in on numbers.  Over 150 technicians and engineers worked more than 1,000 days and ran over 1,000 test flights to bring the Ehang 184 to its current level of trustworthiness.  Flights held at the Ehang test flight site in Llanyungang City show the founder using stick and rudder to control the machine.  Xiong Yifang, cofounder and CMO for Ehang, flew …

People waste billions of hours sitting on roads worldwide each year. We envision a future where commuting by eVTOL (electric Vertical Takeoff and Landing) is a safer, faster, and cost-competitive alternative to ground transportation. We have spent the last ten years developing the technologies that have made our full-scale technical demonstrator possible and are now ready to build a commercial version of the aircraft. We’re excited to have attracted the backing of leaders in auto manufacturing, data intelligence, and transportation sectors. —Joby Aviation founder and CEO JoeBen Bevirt (Green Car Congress) A Knack for Making and Attracting Money That backing came February 1st in “funding from investors including Intel Capital, Toyota AI Ventures, JetBlue Technology Ventures, and Capricorn Investment Group, a …

Vahana Flies!  Another Competitor in the Sky Taxi Airspace

Dean Sigler Announcements, Electric Powerplants, Sky Taxis, Sustainable Aviation 0 Comments

Zach Lovering, Project Executive for Airbus subsidiary A3 reports, “Today marks a historic day for Airbus, A³, and the Vahana team. We can now announce our successful first flight. At 8:52AM on January 31, 2018 in Pendleton, Oregon, our full-scale aircraft, dubbed Alpha One, reached a height of 5 meters (16 feet) before descending safely. Its first flight, with a duration of 53 seconds, was fully self-piloted and the vehicle completed a second flight the following day. In attendance was the full Vahana team, representatives from the FAA, and A³ leadership, all coming together to witness this historic accomplishment.” Hovering Autonomously With canards built in Portland, Oregon at Flighthouse Engineering LLC, the tandem-winged, eight-rotor, 745 kilogram (1,642 pound) machine has …

Battery Startup Cuberg Receives Funding from Boeing

Cuberg, a battery startup “Founded based on graduate research work in the materials science department at Stanford,” includes individuals who worked with Yi Cui at the school.  They promote their safe electrolyte as a key element in their new battery.  “Our highly stable proprietary electrolyte enables the use of high-voltage cathodes and lithium metal anodes in a safe and reliable format.” Their video shows the relative safety of that premise.  It starts, though, with a quick review of their manufacturing techniques, which are similar to standard methods used in most batteries. The team, headed by Richard Wang, “Entrepreneur and Battery Scientist,” includes co-founder Mauro Pasta, an Associate Professor at Oxford University.  His Linked In profile includes this note: “Cuberg is …

Solid Carbon Fuel Cell May Mean “Clean Coal”

Dean Sigler Fuel Cells, Sustainable Aviation 0 Comments

For transportation, two types of fuel cells come to mind: PEMs or SOFCs.  A third variety, DCFCs, may have a place in transport systems, and may have advantages in using “dirty” fuels. PEM (Polymer Electrolyte Membrane – or Proton Exchange Membrane) cells use a solid polymer as an electrolyte and porous carbon electrodes containing a platinum or platinum alloy catalyst. They need only hydrogen, oxygen from the air, and water to operate. They are typically fueled with pure hydrogen supplied from storage tanks or reformers. SOFCs (Solid Oxide Fuel Cells) use a hard, non-porous ceramic compound as the electrolyte. SOFCs are around 60% efficient at converting fuel to electricity. In applications designed to capture and utilize the system’s waste heat …

Autonomous Flight designs and manufactures autonomous passenger drones (APD), and is based in both the United Kingdom and the United States.  Founded by Martin Warner, the company joins a growing number of entrepreneurial groups combining drone hardware and “software-based technologies” to provide rapid point-to-point transportation. Warner envisions a wide range of drone-based, battery-powered air vehicles for both commercial and private use, which he calls the “new gold rush in transportation and aviation”.  Autonomous Flight’s website promotes the familiar arguments for rising above gridlock.  The firm’s commercial notes the average American commuter spends 3.5 hours trapped in traffic every month.  The answer is the Y6S, a two-passenger drone that will whisk you from London-Heathrow to Charing Cross Station in only 12 …

When You Wake Up Hungry – Fly to the Bakery!

Electric-Flight.eu reports on three Germans who made a bathtub fly – and used it to fetch pastries.  As the website reports, “The Real Life Guys” are two Darmstadt students and one DB train attendant who shook up the media last week . They connected a bathtub with an aluminum scaffolding and six 9.6 [kilowatt] motors (€1 065 or about $1,191[each]) from the model building sector to 42-Volt batteries and blew it up.”  “Blew it up” means lifting it skyward on the power of what look like six Hacker model airplane motors, capable of putting out 15 kilowatts (20.1 hp) each for 15 seconds.  The 9.6 kW (12.9 hp) output cited in the Electric-Flight article seems realistic for sustained output, and …
