Diamond Aircraft of Austria gave Flying magazine news of its hybrid-electric tiltrotor project – something not announced on Diamond’s own web site.  According to Flying, Diamond will partner with an unnamed “major industrial partner.”  The airplane could become certified within seven years, enabling customers to own a six-passenger vertical takeoff and landing vehicle with ostensibly high speed and the ability to set down virtually anywhere. Diamond founder and CEO Christian Dries says the craft will be powered by two high-output Siemens electric motors with power to recharge the batteries in flight supplied by a pair of Austro diesel engines.  Since there are four propellers, the motors’ outputs would probably be split fore and aft to a pair of rotors.

EADS (European Aerospace Defense Systems), known colloquially as Airbus, highlighted its Paris Air Show chalet at Le Bourget with three  examples of the work from its Innovations Workshops. All projects are part of the European Commission’s “Flightpath 2050” initiative, conceived to reduce carbon dioxide (CO2) emissions 75 percent, nitrogen oxide (NOx) emissions 90 percent and noise  65 percent from 2000 levels by 2050. EADS thinks electric and hybrid propulsion could become an alternative to fossil fuels within that timeline, with several projects highlighting, “the willingness of EADS to invest in technologies that today, tomorrow, will further reduce emissions of carbon dioxide from aviation.” E-FAN Working with Aero Composites Saintonge (ACS), the IW Research and Technology Group has developed and built the …
