Americans often speak of the $100 hamburger, the food of choice at some airport café a Cessna hour away from one’s home base. The trip to eat and return often accounts for that sum, with avgas stretching toward $6.00 per gallon. Imagine, then, making a coast-to-coast trip across one’s native land, surveying a dazzling array of scenic delights and partaking of French cuisine along the way – all for not quite that amount. Europe abounds in small, turbocharged Diesel automobiles, sometimes zippy little things that exhibit excellent fuel economy. Many of these cars strive for the “3-liter” designation – the ability to drive 100 kilometers (62 miles) on three liters of fuel (78.4 miles per gallon) and the European Union is pushing toward 95 grams of CO2 emissions per kilometer by 2020. Serge Pennec has built several airplanes using these torquey engines, creating a means of traversing distances cheaply and as greenly as possible. Diesels consume their heavier fuel more frugally than …
Greenelis GFC Contender Makes Paris Air Show
A trio of plane makers was seen pushing a trailer with an aeronautical looking object into the Paris Air Show last week. It turned out to be the Greenelis PXLD, a Green Flight Challenge flyer, and it looked a great deal like the offspring of the Dieselis and the Gazaille, two French light sport aircraft powered by converted Diesel automobile engines and designed by Paul Lucas. Like its predecessors, it is made of wood and plywood, but in this case has a wing spar built of carbon fiber with “innovative geometry” and a wing covered with plywood. Greenelis’ fuselage has wooden formers and longerons, and like its forbearers, a plywood shell giving its aerodynamic form. The 11 meter (35.2-foot) span, Two-place side by side craft is powered by an 800 cc Mercedes Smartcar turbocharged Diesel engine that produces 30 kilowatts, or 42 horsepower. A single retractable, center-line landing gear (with outriggers) helps give the 275-kilogram (605 pounds) empty-weight airplane a 220 kilometer …
