Researchers
from m the University of Cambridge in association with Boeing,
have successfully tested the world's first aircraft powered
by a parallel hybrid -electric system.
An electric motor and petrol engine works together to drive the propeller .
The demonstrator aircraft uses up to 30% less fuel than a comparable plane with a petrol- only engine.
The aircraft is also able to recharge its batteries in flight ,the first time it has been achieved
During take off and climb , when maximum power is required ,the engine and motor work together to power the plane.,but once cruising height is reached , the electric mot or can be switched into generator mode to recharge the batteries or used in motor assist mode to minimize fuel consumption
Paul Robertson of the Cambridge Department of engineering says,until quite recently the batteries needed for a hybrid electric air plane were simply too heavy for the job.But newer batteries are substantially lighter , which has allowed research on hybrid power train,for airplanes to take off.
While the Cambridge demonstrator is an important step in the development of hybrid or fully electric aircraft , more research is required before commercial airliners will be powered entirely with electric motors.
