CriCri

Electrical Cri Cri

The first electric Cri-Cri airplane was airborne Thursday – for all of seven minutes. The all electric aircraft, jointly developed by EADS Innovation Works, Aero Composites Saintonge and the Green Cri-Cri Association, made its official maiden flight at Le Bourget airport near Paris on Thursday, Sept. 1.Â

“This aircraft flies very smoothly, much more quietly than a plane with conventional propulsion”, said Didier Esteyne, who piloted the all-electric Cri-Cri. “But we are still at the beginning and have a lot to learn.”Â

The Cri-Cri was originally designed in the early 1970’s by a French aeronautical engineer, Michael Colomban, as the smallest twin-engine airplane in the world.

His goal was to build a very small and economical plane powered by two engines, that would be capable of flying even some aerobatic maneuvers. He also wanted not to exceed his budget over 1000 USD, including two engines, which was quite hard to believe even in early 70s.

At only 4.9 m (16.1 ft) wingspan and 3.9 m (12.8 ft) length, it has become a well known airplane around the world. It is a single-seater, which can even be transported on top of a car. It sort of reminds you of a model airplane on steroids.

Construction time took around 1500 hours for the first airplane and it became a reality in 1973, when it was given the name “Cri-Cri” after Michel Colomban’s daughter, who was often called “Cri-Cri”.Â

The airplane has now been modified and expanded into a 4-engine aircraft with electrical and environmental friendly motors!  The plane has lithium batteries and four electric prop motors that don’t emit carbon dioxide like standard aircraft.

 The Cri-Cri is made relatively lightweight to compensate for the weight of the batteries, the company said. It is CriCri2capable of 30 minutes of cruising and will fly at about 68 mph.Â

There is currently a lot of effort being put into making aviation environmentally friendly. Besides the Cri-Cri, there are also larger projects in the works.

The photo below shows a project currently being worked on by MIT, for an airplane which is estimated to use 70 % less fuel than a conventional aircraft and is designed to carry 180 passengers. The aircraft is referred to as the “double-bubble”. The design uses long, skinny wings, a small tail and – hence the name – replaces the traditional cylindrical fuselage with a two partial cylinders placed side-by-side.
