The Highs and Lows of Human-Powered Flight
On March 19th 2012, YouTube user jarnosmeets80 uploaded a video to YouTube entitled "Flying like a bird | part 14/14." In it, a man donning a set of homemade wings and a helmet with a GoPro attached achieves what many wishful-thinkers, scientists and millennia of wingless bipeds have long dreamed of doing: flying. Sadly, one month later the video's creator, filmmaker Floris Kaayk, admitted the whole thing was an elaborate hoax. Skeptics will have been quick to dismiss the video straight away, and anything more than a cursory Google search might have convinced most of the same. But, with more than 7 million views at time of this writing, it's pretty clear that as a land-based species, it doesn't take much for us to suspend our disbelief at the idea of being able to fly. Even if it is just for one minute and 50 seconds. Head past the break to read more.
Gamera II hits new high with unofficial human-powered helicopter altitude record (video)
The University of Maryland team responsible for the Gamera II human-powered helicopter NAA flight time record may be on its way to bagging another one -- this time for altitude. With new freshman pilot Henry Enerson spinning the cranks, the gigantic four-rotor design ascended to eight feet, an unexpectedly lofty level, according to the team. The well-controlled 25 second flight was far less than the record 49.9 seconds Gamera achieved earlier, but the new altitude bodes well for its upcoming Sikorsky Prize attempt. That $250,000 award, unclaimed since 1980, requires a 10-foot altitude to be maintained for one minute, and now looks to be distinctly in the UMD group's sights. Check the video after the break, and marvel at the ungainly quadrocopter's latest aerial exploit.
NAA verifies new US record for human-powered helicopter flight (video)
A team at the University of Maryland has been taking human powered flight to new heights. Or, rather, lengths, by setting a new US record for flight duration of 49.9 seconds with its Gamera II rotorcraft. The benchmark event actually took place in June, but only received the all important plaudits from the National Aeronautic Association on August 9. Gamera II builds on its predecessor (unsurprisingly, Gamera I) by featuring improved transmission, rotor design and a redesigned cockpit. Not content with smashing the previous craft's record of 11.4 seconds, the team plans to fly a further refined version of the copter with longer blades and other fine tuning later this month. The 49.9 second flight has also been submitted to the Fédération Aéronautique Internationale for World, rather than American-record verification. The guys at Maryland might want to keep an eye over their shoulders though, as it looks like someone else already has their eyes on that prize. Video evidence after the break.
Insert Coin: Atlas human-powered helicopter gunning for elusive Sikorsky prize (video)
In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you'd like to pitch a project, please send us a tip with "Insert Coin" as the subject line. The AeroVelo group, a team of students and professional engineers, wants its Atlas helicopter to hover for one minute, reaching at least three meters (10 feet) powered by human muscle alone. If the grunt-powered machine succeeds, it'll nab the American Helicopter Society International's $250,000 Sikorsky Prize, which has gone unclaimed since it launched in 1980 -- with the best efforts barely leaving the ground. But the University of Toronto-based team reckons it has the chops, with two PhDs aboard and Snowbird, the first successful human-power ornithopter, under its belt. The Atlas will feature four rotors like a 1994 design from Japan, which flew for 19 seconds, a simple and stable configuration that required less pilot power than other models. The would-be flyers have rustled up more than $27k toward the $30k target with 35 hours left, so if you'd like to help out -- and fulfill the dream of eccentric inventors everywhere -- hit the source link for details.
Snowbird ornithopter sets record for human-powered flight (video)
In August this year, a Canadian engineering student achieved a first -- in fact, one of the last firsts in aviation. A human powered ornithopter (a craft that flies by flapping its wings) flew for 19.3 seconds, traveling some 475 feet at an average speed of 15.9 miles an hour. Built by University of Toronto grad students Todd Reichert and Cameron Robertson, the project required that the pilot (Reichert) lose 17 pounds, maintain a special diet, and train daily. Named Snowbird, the craft weighs under 95 pounds and has a wingspan of some 105 -- comparable to a Boeing 737. It was towed aloft by a car, after which the pilot pumped a set of pedals with his feet, which caused the wings to flap. Unlike previous attempts in the past, the Canadian group was able to provide telemetry data to prove that the craft flew under its own power. On confirmation by the Federation Aeronautique Internationale, the craft is set to receive the award for the longest sustained flight by a human-powered ornithopter. Video after the break.
