https://mediacentre.easyjet.com/en/...-a-series-of-technological-milestones-in-2018easyJet will also continue to work alongside US-based start-up and electric aircraft pioneer Wright Electric on their development of an all-electric commercial aircraft and expects to launch the first flight of a hybrid nine seat aircraft within the next 12 months.
A new video produced by Wright Electric shows the progress of this pioneering project, demonstrating contra-rotating propeller technology which is one of the innovations driving Wright Electric’s development of electric aviation. This concept was invented over a century ago and is a more efficient means of propulsion. Electric motors will be able to deliver this more easily than jet engines and it will be a crucial element of Wright Electric's all-electric passenger aircraft.
Johan Lundgren, easyJet’s Chief Executive Officer commented:
"Our aim is for easyJet to go from strength to strength in 2018. I’m incredibly pleased that the hard work and energy of our people will enable easyJet to achieve a number of technological and environmental milestones in 2018.
“Our newest Airbus neo aircraft will continue to reduce our carbon and noise footprints, which have already been reduced by 38% and 50% respectively since 2000, compared to current aircraft.
“Our partnership with Wright Electric will reach a number of milestones in the development of an all-electric commercial passenger aircraft and towards a future which isn’t wholly reliant on jet fuel.”
Jeffrey Engler, CEO of Wright Electric commented:
"Working with easyJet to develop the next generation of air travel is a powerful validation of our technology approach. We’re incredibly excited to be reaching the first significant milestone in this pioneering project towards developing and commercialising our electric aircraft for the large and growing short-haul flight markets.
“easyJet’s impressive team continues to provide valuable insights to our engineers about the critical aspects required to run a successful airline, from maintenance to revenue management, and we look forward to reaching further milestones in the years ahead."

Bingo....A meno che non pensino di recuperare energia in discesa sfruttando il windmilling..

A corollary of this is that, particularly in air breathing engines, it is more energy efficient to accelerate a large amount of air by a small amount, than it is to accelerate a small amount of air by a large amount, even though the thrust is the same. This is why turbofan engines are more efficient than simple jet engines at subsonic speeds.
