The first ever hybrid aircraft to be able to recharge its batteries took off thursday — potentially signalling the beginning of a new form of low-carbon, green flight.
Cambridge University researchers teamed up with Boeing to make the plane.
They hope that the plane will be able to provide new forms of cleaner, low-carbon air travel.
Hybrid engines — which are gaining popularity in cars — combine a battery and a petrol engine. Doing so uses 30 per cent less fuel than a plane with a petrol-only engine.
The petrol engine works with the battery-powered one at take-off and climb, when the plane needs extra power, but the electric motor can then switch into generator mode and recharges the batteries, or help the motor in minimising fuel consumption. The same technology is used in hybrid cars.
The technology is still far from able to be put on commercial airliners, but the move is an important step, researchers said.
The test flights took place at Sywell Aerodrome near Northampton. The plane did a series of small hopes along the runway before taking off for evaluation flights at over 1,500 feet.
