The all electric Cri-Cri, 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. This Cri-Cri is a four-engined all-electric aerobatic plane, which was first shown at the Green Aviation Show at Le Bourget in June.
“This aircraft flies very smoothly, much more quietly than a plane with conventional propulsion,” said Didier Esteyne, who piloted the all-electric Cri- Cri for the seven-minute flight. “But we are still at the beginning and have a lot to learn. We are allowed to start aerobatic maneuvers only after five hours of flight and 15 landings.”
“The Cri-Cri is a low-cost test bed for system integration of electrical technologies in support of projects like our hybrid propulsion concept for helicopters,” stated Jean Botti, EADS’s Chief Technical Officer. “We hope to get a lot of useful information out of this project.”
The aerobatic plane incorporates numerous technologies such as lightweight composite structures that reduce the weight of the airframe and compensate for the additional weight of the batteries, four brushless electric motors with counter-rotating propellers that deliver propulsion without CO2 emissions and significantly lower noise compared to thermal propulsion, and high energy-density Lithium batteries.
The combined utilisation of these environment-friendly technical innovations enables the Cri-Cri to deliver novel performance values: 30 minutes of autonomous cruise flight at 110 km/h, 15 minutes of autonomous aerobatics at speeds reaching up to 250 km/h, and a climb rate of approximately 5.3 m/sec, according to company officials.
