Man Claims to Fly With Custom-Built Bird Wings
Daniela Hernandez
Using videogame controllers, an Android phone and custom-built wings, a Dutch engineer named Jarno Smeets has achieved birdlike flight.
Update 1:06pm PDT: A Dutch artist named Floris Kaayk has admitted that "Human Birdwings" was an elaborate hoax 8 months in the making.
Update 2:15 pm PDT: We have a follow-up report documenting inconsistencies both in the video and Smeets' online resumes.
Update 11:15 am PDT: The headline of this post has been changed to reflect that we have not confirmed Smeets' claim.
Editor's note (March 21, 8:15 am PDT): The authenticity of this video has been questioned (Gizmodo, The Register), but Wired's preliminary analysis by physicist Rhett Allain found nothing in the video that indicates it must be a fake. We are contacting other experts and will update this post when we have more information. Jarno Smeets has not yet responded to several interview requests.
Smeets flew like an albatross, the bird that inspired his winged-man invention, on March 18 at a park in The Hague.
"I have always dreamed about this. But after 8 months of hard work, research and testing it all payed off," Smeets said on his YouTube page.
Smeets got the idea from sketches of a futuristic flying bicycle drawn by his grandfather, who spent much of his life designing the contraption but never actually built it.
When Smeets began studying engineering at Coventry University in England, he realized the physics of a flying bicycle just didn't pan out. Instead, he drew inspiration from Leonardo da Vinci's wing drawings to build his flying machine. Along with neuromechanics expert Bert Otten, Smeets brought his design into reality
The design is based on mechanics used in robotic prosthetics. The idea is to give his muscles extra strength so they can carry his body weight during the flight.
Smeets (and his arms) did just that today with the help of a pair of 37-ounce wings made out of fabric, according to a press release.
Working with the fabric was difficult because it was very fragile, Smeets wrote on his blog. "It's important to sew the seams carefully, and give the wing shape extra strength without making it too heavy. The top part of the kite will be folded around the ribs to create an aerodynamic shape. For extra lift and control I'll stretch a piece of kite fabric between the legs, as some sort of tail wing."
According to Smeets' calculations, he needed approximately 2,000 Watts of continuous power to support his roughly 180-pound frame and 40-pound wing pack. His arms could only really provide 5 percent of that, so the rest would have to come from motors. His arms and pecs would basically serve to guide the device and to flap the wings.
He built his electronic, wireless wing set out of Wii controllers, accelerometers harvested from an HTC Wildfire Android phone and Turnigy motors.
When he landed after the 60-second flight, he said, "At one moment you see the ground moving away, and then suddenly you're free, a really intense feeling of freedom. The true feeling of flying. A [bleep] magical moment. The best feeling I have felt in my life."
