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 …

A Light Twin in the Business Community

Announced at Friedrichshafen’s Aero Expo and displayed (at least in model form) at the 2013 Paris Air Show, the Elektro E6 is the technology platform for a future, all electric transport aircraft. With low CO2 emissions, noise and vibration, the six-seat, two-motor airplane features full carbon composite structure.  Solar cells on its high wing could help extend the range for this machine to 500 kilometers (310 miles), predicted if battery developments continue at their current pace for the next six years.  The light twin would boast a payload of 480 kilograms (1,065 pounds). The E6 comes about as part of an Agreement of Cooperation between PC-Aero GmbH and EADCO GmbH.  Rosario De Luca’s EADCO (European Aerospace Design Consultants), capable of supporting …

Ingenious e-Genius

At the third annual Electric Aircraft Symposium in San Carlos, California in 2009, designers from Germany and Slovenia showed their plan for a hydrogen-powered aircraft called Hydrogenius.  Today, a newly constructed, battery-powered “e-Genius” (developed along parallel lines with Hydrogenius) will be Eric Raymond’s mount for the July 10-17 Green Flight Challenge in Santa Rosa, California.  Eric writes that “e-Genius is now flying, and has reached the required 100 mph.” Hydrogenius’s original layout, replaced for the Green Flight Challenge with a simpler lithium-polymer battery-only system.  1 – Hydrogen tank 2 – Radiator 3 – Stack Module (Hydrogen Fuel Cell) 4 – System Module (Hydrogen Fuel Cell) 5 – Power Distribution Unit 6 – LiPoly Battery to start the fuel cell system 7 – …

Being Led By The Nose

With speculation in CAFE circles about the use of thin, lightweight motors now available for landing and takeoff augmentation, it comes as almost now surprise that DLR, the German Aerospace Centre, and the Airbus people at EADS have announced development of an electric nose wheel that could replace airport tugs and extended ground operation for airliners’ jet engines. According to The Engineer, a British publication, a fuel cell-powered system delivers electrical energy capable of powering the nose wheel of a 70-ton aircraft.  “Commercial aircraft could cut their on-ground emissions by one quarter with a new hydrogen fuel-cell propulsion system, according to its creators. “For short-haul aircraft that often take off and land seven times a day, this could save between 200 …

What’s Small and Green and Has Four Motors?

At the extremely opposite end of the scale of its big brothers and sisters in the Airbus family, the Green Cri-Cri graced EADS’ (European Aeronautic Defense and Space) display at the second Green Aviation Show  (L’Aviation Verte) held at Le Bourget’s Aviation and Space Museum (Musee’ de l’Aire et de L’Espace) between June 18 and 22, 2010. LIke its bigger siblings, the Cri-Cri has four motors, two on each nose pod protruding on stalks like insect antennae from the nose of the miniscule craft and driving counter-rotating propellers.  The two small outrunner motors on each pod appear to spin with the propellers, and are probably concealed inside the spinners. EADS Innovation Works partnered with Aero Composites Saintonge and the Greencri-cri …

An LSA With the Electric Heart of an Airliner

Dean Sigler Electric Powerplants, GFC 9 Comments

Stephan Boutenko, Alternair President and founder, seeks a Light Sport Aircraft alternative, an airplane looking like an LSA, but loaded with features that will allow it to keep pace with the rapidly changing options coming to electric flight. Inspired by Yuneec’s E-430 but disappointed by its slow cruising speed, Boutenko was determined to create something more in line with LSA performance criteria. He also wanted to take advantage of the knowledge he had gained from years of experience with heavier aviation to create an integrated system that would allow flexibility and expandability in the development of his airplane. Unabashedly conventional in appearance, the low-wing, tricycle geared monoplane is conceived to make a pilot transitioning from an internal combustion powered machine …
