Qinetix Motor at E-Flight Expo

Dean Sigler Announcements, Electric Powerplants, Sustainable Aviation 3 Comments

QinetiX GmbH in Germany manufactures a motor and controller combined in one case to lower weight and simplify installation.  Their QPD-40, shown at the Aero Friedrichshafen E-Flight Expo and on their web page, seems to exemplify those goals.  Its 12 kilogram (26.4 pound) weight and 40 kilowatt (53.6 hp.) output gives it a power-to-weight ratio of 3.2 kilowatts per kilogram (2 horsepower per pound). Running on 60 Volts at a maximum 680 Amperes, the motor produces 212 Newton-meters (156.4 foot-pounds) of torque, swinging a propeller at only 1,800 rpm, allowing for quiet operation.  The liquid-cooled stator and power electronics will require some form of heat exchanger, but probably with fairly low cooling drag overall. Only 90 millimeters (3.54 inches) thick …

Five Representative Exhibitors at the E-Flight Expo

Aero, an annual event at Friedrichshafen, Germany, highlights the beginning of the European air show season.  E-Flight Expo has been a regular part of this for the last several years, and displays the latest in electric flight technology.  Certainly the most forward-looking part of the show, the Expo grows every year.  Several exhibitors helped further the advanced look this year. MGM Compro With at least five aircraft powered by their electric power systems on display, MGM Compro showed great market strength.  The Czech firm has 16 of its motors atop each Volocopter 200, with one as a propulsor in the tail.  Their motors power the Magnus e-Fusion aerobatic trainer, several GP gliders, the S.R.O. Song motorglider, and any number of …

Equator P2 Runs Forwards, Backwards and Heads Toward Friedrichshafen

Tomas Broedreskift, on his Equator Facebook page, reports, “Successful motor test with propeller mounted today with #engiro! Celebrating the milestone with some German  (beer glass emoticon) this evening!  (noise maker emoticons) Amazing to see the thing come alive at last.” As the video shows, the Equator P2’s motor can be made to run in reverse, useful for backing out of moorages or avoiding river debris when the amphibian settles on the water.  Engiro makes range extenders on a custom basis for a variety of applications including (surprise!) amphibious aircraft. The Equator P2’s first long-distance trip, 1,361 kilometers (843 miles) from Norway to Aachen, Germany was obviously not by air, but by hand-crafted trailer, to Engiro’s headquarters where the motor tests …

e-Genius Extends Its Range

Dean Sigler Diesel Powerplants, Electric Powerplants, GFC 1 Comment

Shown at the E-Flight Expo at Friedrichshafen’s Aero 2015, Stuttgart University’s e-Genius had an aerodynamic-looking pod next to one wing, containing an ENGIRO range extender consisting of a Wankel-type engine and a generator.  The unit could, as its name implies, help e-Genius go for new records to add to its already significant collection. Bill Lofton at EV Hangar has detailed the extender, now associated with the e-Genius and in a larger variant on the Equator P2 amphibian being built in Norway by Tomas Broedreskift. Equator’s web site describes its power system: “The hybrid propulsion system being developed by Equator is called EHPS (Equator Hybrid Propulsion System). The engine specific project is being co-funded by Transnova and the company doing the development work …

WattsUp Becomes Alpha Electro – Training Market Warms Up

Dean Sigler Electric Powerplants, Sustainable Aviation 2 Comments

With today’s AVWeb report from Mary Grady at Aero in Friedrichshafen, Germany, the wraps are off the commercial reality that Pipistrel is ready to market its Alpha Electro, a new airplane for the training market.   The production version of the former WattsUp, the airplane’s primary mission is to provide training in the pattern for aspiring pilots. Details abound in the video, with Tine Tomazic, Chief Engineer for the Slovenian firm, showing Mary the features of the craft.  One of the best features may be its 100,000 euro price tag, well under pricing for many conventionally-powered light sport aircraft that would compete in the trainer market. Since Aero brings in exhibitors from all over the world and incorporates an E-Flight Expo, …

PC-Aero’s Elektra One

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation 14 Comments

Dipl. Ing. Calin Gologan, an exhibitor and presenter at this year’s E-Flight Expo at Friedrichshafen, will be at the fourth annual Electric Aircraft Symposium, discussing the design and technology he hopes will imbue the winning entry in next year’s Green Flight Challenge.   He notes that the GFC, “the world’s largest prize…awarded in general aviation,” was a major incentive in his pressing forward with an environmentally conscientious design. His Elektra One is part his PC-Aero’s ambitious campaign to fly three different electric aircraft in the next few years, the single-seat “One,” two-seat “Two,”, and most ambitiously, a four-seat “Four.” With at least the shell of Elektra One at the Expo, Gologan is making good progress toward completion of his GFC machine, the prototype for …

Gérard Thevenot Wins E-Flight Award at AERO 2010

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

With over 30 electrical flight exhibitors at Friedrichshafen, Germany’s Aero 2010 International Exposition for General Aviation, selection of this year’s E-Flight Award winner must have been particularly difficult. The”E”of the E-Flight portion of the huge show represents, “Electrical, Ecological and Evolutionary.” Thevenot’s machine is all those. Gérard Thevenot flew his hydrogen-powered ultralight “trike” across the English Channel in July, 2009 (“Man of La Manche”, October 29, 2009), with a Geiger/Eck HP-10 electric motor powered by a hydrogen fuel cell, “without the onboard presence of an accumulator or battery.” Showing his 55 kilogram (121 pounds), seven kilowatt (11 horsepower), 12 meter (37 feet) span ultralight at last year’s Expo, he went on to demonstrate its capabilities in the following months. Its …
