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.

Dr. Brien Seeley, President of the CAFE Foundation, points us toward a video his son Damon just posted to Vimeo.  It depicts part of the 2011 Green Flight Challenge sponsored by Google, for which the Foundation played host. Dr. Seeley explains, “NASA’s Chief Technologist Joe Parrish refers to the Wright Brothers in the video as Sonoma County Supervisor Mike McGuire and I cut the hose to a gasoline dispenser nozzle.”  The symbolic hose is then proudly replaced by a very real electric charging station for airplanes, capable of providing a continuous 9,600 Watts to each of 12 aircraft and used to charge the Pipistrel G-4, e-Genius and Embry-Riddle’s hybrid Stemme during the contest. The video features great in-flight footage of …
