The 2018 Sustainable Aviation Symposium was a master class in aircraft design, electric and hybrid power, and the strategies that will make green flight a reality in our near and distant futures.  The considerable knowledge imparted in that gathering is now available for your education and enlightenment on YouTube. Better than (Most) Cat Videos Go here to see the entire 2018 Symposium program, complete with links to a video of each speaker’s talk. Or go here for the library of presentations on YouTube. Either link provides high-quality video of the 20 presentations from this year’s Sustainable Aviation Symposium.  You will see all the slides in each presentation and hear each presenter’s eloquent exposition.  These range from the simplest of garage-based …

Sustainable Skies in San Francisco

I’m writing this in the first person, rather than the usual third-person voice that allows me to remain objective about things on which I report.  In this case, I have been the recipient of much joy over the last ten years from being an observer of the ongoing progress in electric aviation. Dr. Brien Seeley, founder of the Sustainable Aviation Foundation, asked me to begin writing a blog about electric aviation in 2009.  One of my original postings concerned a Kitplanes Magazine contributor, David Ullman – who was this year’s Sustainable Aviation Symposium’s keynote speaker.  In 2009, he predicted a great future for electric aviation – most of which has come to pass, and some of which he is creating …

Goshawk Goes Electric

The GosHawk was conceived as an electric aircraft and technology has FINALLY caught up with it, according to designer Greg Cole. Its sailplane-like proportions allow it to fly with the smallest of power inputs, and real soaring is possible with the electric propulsion system completely shut down, Greg says.  This author finds it suits its namesake with a sporty nature and a natural beauty. The GosHawk is also planned in two additional versions with internal combustion engines. The HKS 700E engine is a fuel-efficient two-cylinder unit seemingly ideal for motorgliders or touring gliders. His airplane with this engine’s 56 horsepower available can attain a 100 mile per hour cruise at a fuel consumption of 100 miles per gallon, or 200 …

Albatross, Dragonflies, and Hummingbirds

Your editor took a trip to Tehachapi, once home of the infamous California Women’s’ Correctional Institution, mentioned in no less than three 1940’s films noirs.  (It’s now a gray-bar hotel for bad boys, not bad girls.)   Lesser offenses were in mind, though, since Labor Day weekend has been the time for 31 meetings of the Experimental Soaring Association’s Western Workshop.  The group, devoted to improving sailplanes and testing the limits of soaring technology, has been in the forefront of many significant developments, and its members include many record holders and aerodynamics experts. This year’s convocation included talks on birds, dragonflies (the Libelle sailplane), and even a demonstration of Aerovironment’s spy hummingbird, a camera-toting drone no larger than a 90-percentile member …
