Ken McKenzie, listed as Deputy Chairman of Airbus US, has served as Vice President for Airbus Customer Services and as Chief Operating Officer for Airbus Americas, Inc. This high-powered individual comes across as a relaxed, congenial soul, though, and led attendees at the ninth annual Electric Aircraft Symposium through an overview of developments in light electric aircraft to come from the aviation giant. The e-Fan is the most visible effort for Airbus’s electric aircraft work so far, but the company is intent on carrying out a full E-aircraft program as part of its commitment to the European Commission’s Flightpath 2050 program,. which bullet-points these important goals for the next 35 years: “1. In 2050 technologies and procedures available allow a 75% reduction in CO2 emissions per passenger kilometer to support the ATAG (Air Transport Action Group) target10 and a 90% reduction in NOx emissions. The perceived noise emission of flying aircraft is reduced by 65%. These are relative to the …
etlantic to Tackle the Atlantic – Both Ways!
Having pushed his electric Colomban MC-30 Luciole (Firefly) to its limits and having won the Federation Aeronautique Internationale’s approval of his speed and altitude records, Jean-Luc Soullier and his team partner Roman Marcinowski are now after significant distance, speed and altitude goals. Needing a faster, lower-drag airplane to accomplish the next set of tasks, the etlantic Project turned to Greg Cole at Windward Performance in Bend, Oregon. Cole’s Duckhawk 15-meter sailplane outflew even 18-meter competitors in its first contest year. At a gross weight of 960 pounds (using the Windward specification), the special Duckhawk’s three-bladed propeller (special in itself) will have to overcome under 19 pounds of drag to maintain level flight at the best lift-to-drag speed. But the plan is to fly high and fast to set new world altitude and speed records. A lighter version of the base airplane, weight saved with thinner wing and fuselage skins, will allow carrying batteries and thin-film solar cells to power the …
Would You Believe There Are Four Electric Cri-Cri’s?
Three electric MC-15 Colomban Cri-Cri’s have been flying for at least the last two years. Jean-Luc Soullier created one which flew with Plettenberg model motors. Airbus crafted one with four Rotex motors and counter-rotating propellers on each mount. Anne Lavrand’s Electravia converted a Cri-Cri to use her motors for speed record attempts. Now they are joined by the MC-15E built by Mr. Toon Jacobs and shown at the Federation RSA ( Network of Sport Air ) Rally 2013 in Vichy, France. The RSA, as one would guess, is the French equivalent of America’s Experimental Aircraft Association (EAA). Electravia provided the E-Motor GMPE 104 motors, controllers, E=Helices 370 gram (one pound, 13 ounces), 83 centimeter (32.7 inches) propellers and the E-Batts 3 kilowatt-hour battery pack. An Electravia E-Screen instrument monitors battery charge, temperature, and motor temperatures. Powerplants match those developed in 2010 for Cri-Cri Yankee Delta in which Hugues Duval set a world speed record for electric aircraft before a huge crowd at the 2011 Paris Air …
Czech Republic Flies Electric Sportplane
Sold in America as the SportStar Light Sport Aircraft (LSA), the Czech all-metal two-seater has a 28 foot, 5 inch wingspan, a maximum takeoff weight of 1,320 pounds typical of LSAs, and is normally powered by a Rotax four-cylinder engine. The latest version of this airplane, though, took flight in Kunovice, Czech Republic on March 28, powered by a Rotex motor. The SportStar EPOS (Electric POwered Small Aircraft) is derived from Evektor’s RTC, and carries a 50 kilowatt (67 horsepower) RE X90-7 motor made by Rotex Electric, which crafts everything from small model aircraft motors to (as shown on their web site) 40 kilowatt (53.6 hp) outrunner-appearing motors for electric vehicle use. The X90 designation would seem to indicate a larger, more powerful model, although that model is not shown on the Rotex web site. For possible interpolation, the displayed 40 kW model weighs only 7.5 kilograms (16.5 pounds), a healthy power-to-weight ratio. Their range of motors is slated for …
