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 last week.
The Cri-Cri is the first-ever four-engined all-electric aerobatic plane. The plane incorporates numerous innovative 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 which deliver propulsion without CO2 emissions and significantly lower noise compared to thermal propulsion, and high energy-density Lithium batteries.
“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.” In the near future batteries will not able to propel larger aircraft.
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.
Cobra International will showcase a range of composite products at CAMX 2018, including carbon fibre components for the automotive, transportation, marine, water sports and luxury sectors.
UK company Prodrive Composites has developed a process for manufacturing recyclable composite components that can satisfy future end-of-life requirements without any compromise in the performance of the original parts. The company says the P2T (Primary to Tertiary) process not only simplifies recycling, but endows a composite material with the potential to fulfil three or more useful lifetimes.
Designers at Elemental Motor have utilised tailored fibre placement (TPF) to extend the use of carbon composites in its RP1 sports car.
