Green Cri electric acrobatic airplane hits the skies


There is nothing quite like the feeling of flying really high, overlooking the vast lands below while being closer to heaven than most. Well, the Green Cri is one such personal aircraft, being an electric acrobatic airplane that was the star of the recent Paris Green Air Show. This is an experimental aerobatic electric aircraft which actually hasn’t spent a single second in the air, although in theory it ought to be able to duke it out with the rest of the migratory geese and other feathered friends. Featuring a quartet of engines, gorgeous smooth lines and intriguing bubble pilot enclosure, the Green Air comes in a form factor that will definitely appeal to just about anybody and everyone. What’s all the fuss about the Green Cri anyway? Well, head on after the jump for more information.

The Green Cri was developed as a scientific research aircraft by EADS Innovation Works and Aero Composites Saintonge. Needless to say, the name itself suggests it was based on the limited, yet popular, short range MC-15 Cri Cri ultralights which was originally constructed in the 1970s, featuring similar dimensions as the MC-15 with a wingspan of just over 16 feet and being some 12 feet 10 inches long and 4 feet in height. One thing that sets this apart though would be the lack of fuel engines in front of each wing, instead, the Green Cri test prototype comes with four high voltage, low intensity brushless electric motors with counter-rotating propellers. In order to make sure the aircraft remains light, it uses lightweight carbon composite structures as part of its build, helping balance out the 26.8kg four pack of Lithium Polymer batteries, where each of them provide 100V (5Ah). Should it actually take off, the overall weight (including the pilot) will be just 175.5kg.

With sufficent modification made to the design and integration of the electric engines, this has resulted in a 20% to 30% aerodynamic efficiency gain, which should be able to help the aircraft achieve 30 minutes of cruise flight at 110kph, or 15 minutes of aerobatics at up to 250kph on a single hour-long charge of the batteries. We’d hate to be in this when the aircraft runs out of juice, so the pilot had better keep a keen eye out of battery levels and land safely whenever a warning light or message flashes. Could this usher in a new era of zero emission aircraft?
