Controversial at CES 2016

Making a lot of column inches of traditional newsprint and reigning as clickbait on the Internet, the Ehang 184 is an eye-catching Autonomous Aerial Vehicle (AAV) causing a bit of controversy in the media.  Unveiled at this week’s Consumer Electronics Show (CES 2016), it drew concentric circles of photographers who normally save their enthusiasm for the lovely models showing off the newest iPhone or PlayStation. Coming from a firm that already makes hobby drones, the 184 (one passenger, eight motors, four arms) can carry its trusting passenger up to 20 miles, depending on who’s reporting.  Its 14.4 kilowatt-hour battery pack allows a maximum of 23 minutes of flight, and at 60 mph, a quick hop to a nearby destination, which …

EAS VIII: Joby Motors – on Simple and Complex Airframes

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

JoeBen Bevirt, founder and CEO of Joby Aviation, Joby Motors, and related enterprises, has thought long and hard about the financial costs and lost productivity brought about by the daily automotive commute, a 1.6 hour per day ordeal for many in our urban centers.  JoeBen and the Atlantic magazine agree that commuters squander 5.5 billion hours and 2.9 billion gallons of fuel annually, stuck in the fitful despair of slow or unmoving traffic, sharing only frustration and polluted air with their fellow motorists. JoeBen told attendees at the April Electric Aircraft Symposium that several years before, he had the seeming pipe dream of moving people by air in a single-seat, eight-motorm, vertical takeoff and landing, electric commuter aircraft that would …

Electric Gull Flies at Arlington

The annual fly in at Arlington, Washington was an electric landing zone for Mark Beierle’s Gull 2000, powered by his own design 20-kilowatt motor.  The 36-coil, 42 magnet disk, weighing 16 pounds, is mounted on a truss arrangement behind the airplane’s high wing, and drives a ground-adjustable pusher propeller. Flying five half-hour demonstration flights during the half-week event accounted for almost half the six hours total time on the airplane so far. The airplane has a 74-Volt Rhino Lithium-polymer battery pack made up to 11 packs in a parallel/series arrangement. Beierle says this array, and taking voltage from the ends of each 3.7-Volt series pack, allows balancing of all 210 cells. Power is run through a 500-Amp Kelly controller, which weighs …
