4-Engine Electric Cri-Cri Unveiled by EADS
June 24, 2010 — At the Green Aviation Show held this past week at Le Bourget, Paris, EADS created quite a buzz when the company unveiled what it calls the first-ever four-engine electric-powered aerobatic airplane, based on the tiny Cri-Cri homebuilt designed by Frenchman Michel Colomban in 1973.
Working in partnership with Aero Composites Saintonge and the Greencri-cri Association, EADS Innovation Works used composite materials instead of metal to reduce overall weight and make room for the high-energy-density lithium batteries. Those cells provide power to four brushless electric motors – two mounted back-to-back on nose pods on each side - with counter-rotating propellers.
EADS Innovation Works claims the aircraft will have “novel” performance: 30 minutes of cruise flight at 110 km/h (68 mph); 15 minutes of full aerobatics at up to 250 km/h (155 mph); and a climb rate of approximately 5.3 m/sec (1,020 fpm).
EADS expects to make the first test flights this week.
