I guess it's time to stop calling helicopters 'choppers' and use 'whipper' or 'buzzer' etc.
MartinCh,
Buzzer would be quite apt for
this rotorcraft from EADS.
Word from Germany is that EADS Innovation Works, the corporate research and technology arm of EADS, will unveil at the ILA show in Berlin next week a full-scale mockup of a helicopter powered by an innovative two-stroke diesel engine as part of hybrid electric propulsion system for the vehicle.
The company says such a design could cut fuel burn and emissions by 50% while cutting noise with electric-only takeoffs and landings
