Electric Green Taxiing System Quietly Enters Paris Air Show

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

Honeywell and Safran have teamed up to create EGTS International, a company that makes Electric Green Taxiing Systems for airliners.  Honeywell has extensive experience with auxiliary power systems and Safran makes “world-class landing gear systems.”  Put them together and you have the self-powered landing gear which made its public debut at the Paris Air Show this week.   Others have been working on the same type of system, but  EGTS is the first to show the technology off at an air show. Besides making the display Airbus A320 one of the quietest airplanes moving across the tarmac at the show, the system could save airlines up to four percent per flight on fuel burn.  As the EGTS web site explains, …

Solar Impulse Shines in a Grand Finale

Nature’s vagaries threatened Solar Impulse’s planned flight all week at the 2011 Paris Air Show at Le Bourget Field, but the clouds parted company, the sun shone brilliantly, and the giant airplane delighted the huge crowd with its extremely slow pass down the main runway. Bertrand Piccard and André Borschberg, co-founders of the project, had accomplished what they set out to do – make believers in a clean, bright future of emissions-free flight. According to the project’s web site, “Gilles Fournier, President of Le Bourget airshow, declared afterwards: ‘This flight was the highlight of the air show. 30’000 people saw it this morning, and there was a very strong emotion amongst the crowd. This very intense moment reminded me of …

EADS Pulls Off Electric Hat Trick at 2011 Paris Air Show

At the 2011 Paris Air Show at Le Bourget this week, the European Aeronautic Defense and Space Company N.V. (EADS) showcased at least three electric flight vehicles – two emonstrating current reality and one pointing toward a cleaner future for short-to-medium range airliners. Cri-Cri, the four-motored, contra-rotating props on stalks aerobatic wonder, did indeed perform at the 2011 Paris Air Show, doing six-minute routines daily at the show.  Didier Esteyne, the plane’s obviously accomplished pilot, explains things in this video. Emmanuel Joubert, Program Head for the All-electric Cri-Cri at EADS, explained the plane’s advantages.  “In all-electric mode, the plane’s performance during climb and aerobatics is better compared to a conventional aircraft of this type.  This allows the pilot to really …

Solar Impulse Inspires in Brussels, Heads to Paris

On June 14, 2011, Andre’ Borschberg guided the giant Solar Impulse from Brussels, Belgium, where the craft had spent the last week as the centerpiece of discussions on green energy and the future of transportation in the European Community, to Le Bourget Field just outside Paris.  Nearing its destination, its daylong flight sometimes resembled the mathematical problem called, “the drunkard’s walk,” as Borschberg was vectored around the aerial neighborhoods surrounding Paris to make certain the lightly loaded craft did not run afoul of  jetliners’ wakes and could find a slot where the runway did not present residual turbulence.  During the preceding week, VIPs from the European Community gathered aound the airplane in Brussels to discuss the importance of this airplane and …

An Airplane With a Familiar Rung to It

APEV, the Association Pour la Promotion des Eschelles Volantes, or the Association for the Promotion of Flying Ladders, began life creating Pou de Ciels (Flying Fleas)  based on a fuselage made from a popular, commercially-available aluminum ladder (“Electrified Minions of Mignet,” February 1, 2010).   The ease of construction made these a big hit in France, and the group’s latest effort, an aluminum and Diatex 1000 fabric tribute to Alberto Santos-Dumont’s Demoiselle, appeared at last weekend’s Green Aviation Show at Le Bourget Airport in Paris, France. The Demoichellec (the name comes from the use of l’echelle, or ladder, and the “ec” indicates an electric powerplant) is the latest brainchild of the APEV people.  Although legal threats caused them to give up the …

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 …
