Hoversurf, a Russian flying motorcycle, has been getting a lot of press lately. “Looks like a hell of a ride,” trumpets TheNextWeb. Mashable headlines, “The first manned hoverbike could finally fulfill your ‘Star Wars’ dreams,” but points out, “Those dangerous-looking propellers spinning right next to the pilot’s legs.” New Atlas (formerly Gizmag) says it is, “Equally amazing and horrifying.” Hoversurf’s Scorpion evokes Star Wars with its clean white gloss. But like the movie’s speeder bikes flung about by heroes and villains alike, seems equally dangerous with its wooden propellers at two different heights – ankle-biter and knee-slapper. Protective shields theoretically will prevent slicing and dicing, and future plans call for an enclosed cabin with the occupant more secure from maceration. Some qualms persist. Rivals like e-volo’s Volocopter spread lift over 16 propellers, and the eHang 184 has eight blades. The lack of redundancy at the four corners might be a problem if one motor or reduction belt fails. Rivals feature …
EAS IX: Dr. Seeley’s Magnum Opus
Your editor first met Dr. Brien Seeley, founder and President of the CAFE Foundation, at the Western Workshop for the Experimental Soaring Association in 2007. Dr. Seeley spoke about the CAFE Foundation and its many areas of research, including its first two Electric Aircraft Symposiums. Seven years later these events and this blog are among the few resources for people seeking information on this developing field. He spoke then about a novel idea, an aerial taxi service that would eventually become fully autonomous, hauling people on short-to-medium range trips in small, electric aircraft that would fly out of very small airports. This seemed a bit of science-fiction at the time, but Dr. Seeley has continued to promote this idea, gaining valuable allies and convincing growing numbers that this is a practical alternative to the wasteful clogs on our nation’s highways, taking their toll on time, treasure and the human spirit. At this year’s Electric Aircraft Symposium, he shared the mature …
EAS VIII: Bruno Mombrinie and Dr. Brien Seeley – Economies and Practical Considerations for Sky Taxis
Bruno Mombrinie, a director for the CAFE Foundation, and Dr. Brien Seeley, founder and President of the organization, gave a one-two presentation on pocket airports and Sky Taxis that examined the practical and operational facets of such a program, first described in detail in a joint NASA/CAFE Foundation document. According to Bruno’s CAFE biography, “As a freshman, he helped build MIT’s Chrysalis human powered airplane. Later that summer he got to fly the plane several times. ‘The feeling of being so, so high (39ft)…to fly under my own power was beyond…I just wanted to burst…actually I was so out of breath from the effort, I could hardly mouth ‘yippee!’” (The Chrysalis, and other MIT designs led to Daedalus, the HPA that flew from Crete to Sicily on April 23, 1988 – 72.44 miles in less than four hours.) This experience with extreme pedal power probably helped inspire his work on the Negative Mass two-piece crankset, reputedly the world’s lightest and stiffest bicycle crankset. His …
Aviation Week Recognizes CAFE Foundation’s Efforts
As noted in this blog. Dr. Brien Seeley, President of the CAFE Foundation, has been actively promoting the idea of a short to intermediate range Sky Taxi, a two-seat aerial vehicle that would carry its passengers safely from 420-foot runway “pocket airports” to other such runways at other urban and suburban settings, or even pockets situated within major airports. The safety and utility promised by these electrically-powered aircraft would provide convenient, inexpensive trips for commuters who would enjoy TSA-free travel up to 500 miles at point-to-point speeds exceeding even private LearJets. Aviation Week recently noted efforts by John Langford, CEO of UAV specialist Aurora Flight Sciences, to achieve part of Dr. Seeley’s far-reaching goals with today’s technology. As Graham Warwick reports in the magazine, “Five years after DayJet’s on-demand air service using very light jets ceased operations, the dream of air taxis remains alive. But industry is looking at unmanned aircraft technology as a way to reduce or eliminate the …
Dr. Seeley at AirVenture 2013
Imagine being able to walk one morning from your front door to a nearby small airport, step into an electrically-powered small airplane, point to a destination on an illuminated map on the airplane’s display screen, and be whisked to your destination so quietly that your passage overhead will not wake your neighbors. This is part of the dream that Dr. Brien Seeley, founder and President of the CAFE Foundation, presented to an appreciable and appreciative crowd on Friday, August 2 at the Rotax Pavilion during the Experimental Aircraft Association’s AirVenture 2013. His talk, “The CAFE Foundation’s Green Flight Challenge Program: Toward a New Transportation Mode,” was a roadmap to how the CAFE Foundation, NASA and corporate sponsors will present five new challenges leading to the type of electric short or vertical-takeoff and landing airplane that will enable neighborhood pocket airports. He also challenged EAA members to become involved, using their technical knowledge and talents to further the development of quiet, …
