Great minds tend in the same directions.  Newton and Leibniz both came up with the calculus at roughly the same time, both goaded to develop a way to determine the orbit of Halley’s Comet.  So it’s no surprise that two different groups would come up with similar solutions to developing a backup hybrid system for light aircraft.  Within weeks of one another, Spain’s UC3M and Israel’s Ashot Ashkelon both unveiled add-on hybrid systems for Rotax engines. Aviation Week identifies the second team’s players in its report.  “An innovative hybrid propulsion system (HPS) for light aircraft – manned or unmanned – is being unveiled here at the Paris Air Show. The HPS was developed by an international consortium headed by Israel’s …

EAS VIII: Across the Atlantic – Twice

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

Jean-Luc Soullier, holder of Fédération Aéronautique Internationale records for speed and altitude in an aircraft almost lighter than its pilot, has a greater series of ambitions to expand the range and speed of electric aircraft. Having stretched the limits of his Colomban MC-30e with two different motors, he’s looking at a longer-spanned, cleaner aircraft – the Windward Performance Duckhawk – as a means of getting higher speed and much longer range for a truly formidable (tres formidable) crossing of the Atlantic Ocean, not once, but twice. The airplane, with a Rotex motor on the nose and a specially-designed Arplast three-bladed propeller, will weigh a mere 105 kilograms (231 pounds) empty – without batteries. This is considerably less than the lightest …

Would You Believe There Are Four Electric Cri-Cri’s?

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

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 …

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, …

The Little Firefly That Could

Dean Sigler Electric Powerplants, Sustainable Aviation 2 Comments

This little airplane is the fastest in its category in the world, unofficially. Flying from Koksijde, Belgium’s military airport, it clocked 189.87 kilometers per hour (117.7 mph) over a 15-kilometer straight-line course, a big improvement over its official speed record set on February 27 of this year. It also holds the official altitude and distance record in its class. Designed by Michel Colomban, one of the engineers for the Concorde, the MC-30 Luciole (Firefly) has a structure weighing only 98 pounds, ideal for adding heavy battery packs as part of its electrification. Its Lynch-type motor, controller and batteries were supplied by Anne Lavrand at Electravia, and have flown in the MC-30 for over a year. These are similar to the motors used …

A Different Kind of Hybrid Aircraft

Dean Sigler Electric Powerplants, Sustainable Aviation 3 Comments

A father and son team have done amazing things with the Colomban MC-15 Cri-Cri: Hugues Duval, the son setting a world speed record at last year’s Paris Air Show, and Yves, the father, resurrecting a decade-old airshow act. At an airshow in Gergy-Pontoise, France this year, according to Anne Lavrand, head of Electravia and motor supplier to the little electric speedster, “Spectators were able to admire the return of the famous Shuttle Bretonne,” a Broussard liaison aircraft carrying the Cristalline Cri-Cri aloft. Anne Lavrand explains, “At the end of the 90s, Yves Duval, Hughes’ father, presented in airshows the “Breton Shuttle”: a Broussard with a small Cri-Cri on its top for the take-off, then… during flight, Cri-Cri takes off from the …

Chip Yates Becomes World’s Fastest Person in an Electric Airplane

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

On July 19 at Inyokern Airport in California, Chip Yates and his Long-ESA electric airplane set an unofficial world’s speed record for battery-powered flight, hitting 202.6 mph just before a dead cell in the battery pack forced an emergency landing.  It was the airplane’s second test flight. Following a day of taxi tests, Chip, who has been taking flying lessons and recently achieved his Private Pilot’s license, set out to see how fast his 258-horsepower mount could go.  He has become the first person to break the 200 mph barrier for electric aircraft in level flight, beating the previous record by Hugues Duval at last year’s Paris Air Show in an Electravia-powered Cri-Cri.   Duval managed to hit 175 mph on …

Big Frog Diesel Racer – A Different Kind of Green

Dean Sigler Diesel Powerplants, Sustainable Aviation 2 Comments

There are only 10 Nemesis NXT racers in the world, and one happens to be in France, getting tuned up to compete in this year’s Reno Air Races in about 10 weeks.  On display last month at the Paris Air Show, the lightweight, carbon-fiber racer lacked the usual Lycoming IO-540 engine, a six-cylinder powerplant that cruises the 1,500 pound two-seater at 325 miles per hour. Aviation International News Online’s Olivia Saucier reported, “The Big Frog racer is getting attention for more than just its tongue-in-cheek patriotic name. The French aircraft is the first carbon-fiber race plane to run on a Diesel engine powered purely by jet-A fuel. And it is turning heads here at the Le Bourget show. “Big Frog …

Electravia, Cri-Cri Set Speed Record at Paris Air Show

Anne Lavrand of Electravia in Grenoble, France, shares this exciting news from the Paris Air Show today. “A new speed world record for electric aircraft : 283 km/h ! (175.46 mph) “Hugues Duval holds the world speed record for an electrically powered aircraft after reaching the top speed of 283 km/h during his presentation flight today in the 49th Paris Air Show (Saturday 25th of June, 2011). “This electric Cri-Cri is powered by two electric propulsion systems ELECTRAVIA (35 HP each), two special high-speed propellers E-PROPS and 3 kWh of KOKAM Lithium-Polymer batteries (24 kg). “This flight has shown to key actors of [the] aeronautics world present at [the] Paris Air Show 2011 that electric engines are a real alternative …

EADS Pulls Off Electric Hat Trick at 2011 Paris Air Show

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

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 …
