Human Powered Helicopter Lifts Off

Last summer a team of engineering students from the Clark School of Engineering at the University of Maryland created a human-powered helicopter called Gamera, they managed to get it off the ground and keep it aloft for 11 seconds. However their new model, the Gamera 2 managed to stay airborne for a solid 50 seconds, smashing the world record.

The Gamera II has been improved from its predecessor in many ways. It is 105 feet across, and each of the four rotors are 42 feet long. Thanks to the weight saving benefits of carbon fibre the entire helicopter weighs just 32 kilos, which is over 13 kilos lighter than the previous design.

And if you jumped off a building and glided with just a bed-sheet for longer than 50 seconds, you would be well-and-truly in the record books. You are what I call a “knocker”. You go and build a human powered helicopter and beat the record (if you think you are better than them) dip-shit.

    It turns out piloting a human-powered helicopter takes a lot more than just pedaling your ass off.The official challenge of flying (and powering) a helicopter for at least 60 seconds, to a height of three meters and staying within a 10 meter square has been around since 1980. Several teams have tried, and all have failed.“It’s really a mix of power at the right time and control, and finesse,” pilot/engine Colin Gore told us in describing how to fly one of two helicopters currently trying to win the $250,000 Sikorsky prize.Gore is part of a team from the University of Maryland that hopes to finally claim the human powered helicopter title this weekend and end their heated battle with a team of Canadians also trying to find the perfect balance of power, control and design.The Gamera II is huge. It has four large, slow turning rotors, each nearly 43 feet across, and has a total width of 105 feet. Yet it weighs just 71 pounds. The ultra low weight is accomplished using a carbon fiber truss structure that provides just (barely) enough structural strength to keep it from collapsing. The hyper-delicate nature of the craft poses the biggest challenge to getting it airborne — and keeping it there. Pedaling too hard can cause the rotors to self-destruct.Gore is pursuing a doctoral degree in material sciences at the University of Maryland and one of just five people who fly the human-powered helicopter. Unlike the Canadian design, which basically suspends a bicycle beneath the helicopter, the Gamera II pilot sits suspended beneath the contraption and uses his legs and arms to turn two sets of pedals. Timing is everything.“The blades have momentum and you have to give it time to come up to speed a little before you take off so the impulse you put on it doesn’t break things,” he said. “It’s a delicate craft.”Although the helicopter must achieve an altitude of three meters (~10 feet), it only has to reach that height once. Gore says the key is to meet that requirement as soon as you get the rotors up to speed.“You need to make a decisive moment where you apply full power, climb as high as you can, up above 10 feet,” he says. “Then you let off the power but that transition between climbing and dropping down again, you need to be very careful about maintaining a fluid stroke because if there’s a fraction of a second where you are basically letting go of it, the helicopter is going to drift horribly.”Gore says any large amount of lateral drift quickly gets to the point of being unrecoverable. And when the drift is combined with one part of the helicopter losing altitude, a weekend ending crash is the result.The pilots do have some control beyond applying the power. Gore says the details are a closely guarded secret, but the craft has switches the pilot can engage with their thumbs to exert some measure of control over the rotors.“It’s basically a very clever way of managing the power to each of the rotors so we can correct for drift,” he said.Gore believes the ability to use his arms and legs gives the team an advantage because it smooths out the power strokes during the flight.“We have these dynamic loads, and putting the arms in there is sort of like putting a battery in there where you can manage, level out the peaks of that curve,” he said.The pilots are all students at the University of Maryland. Gore says they initially looked at local cycling clubs and racing teams, but they didn’t get a ton of interest. They also discovered that elite strength wasn’t a guarantee of a good flight. They ended up testing one successful racer from Washington D.C., “but he still weighed 145 pounds,” Gore says.The extra strength didn’t offset the the extra weight. The pilots tip the scales between 120 and 135 pounds. (Insert skinny engineer joke here.)The team spent much of today setting up their helicopter and preparing for this weekend’s flights. If all goes well, they hope to begin making some initial test flights in the morning, and make the first attempts at the prize mid day Saturday.

    If he needs to supply 1hp to keep the rotors at speed, it remains 1hp whether he has a 10lb or 1000lb flywheel. The rotors are enormous flywheels and any additional flywheel would only add weight and transmission losses. If you mean powering up the flywheel on the ground then releasing the power at a greater-than-human rate, that would work better but probably breaks the human-powered rule.

Being highly innovative – though of course by iteration of existing technology as are all inventions to some degree – it both educates the team and advances the state of the art. These students are learning how to be more innovative engineers, those on whom the whole world depends for our great modern way of life.

What you see here is basically a skirtless hovercraft. Three meters will take energy storage in the rotor mass then release it with increased angle of attack. There will be flight duration or height records but not both at the same time. Again great job Team Gamera.

    All methods of flight are based off an exchange of expending energy through drag in the prop blades and wings, but my method applies most of that energy into creating thrust/lift using special max angle of attack prop mechanisms, whereas all traditional methods waste the majority of motor energy by producing several times more rotational prop drag than forward thrust/lift. My method is literally using the drag force on the prop blades as direct mechanical leverage for lift/thrust.

Flying VTOL cars, perfect VTOL jetpacks, you name it- would all be possible and practical with this new method of flight.If I could build a prototype of a human-powered version of this it would only weigh 20 lbs and win the Sikorsky.

    Aside from being an awe-inspiring proof of concept, this project has numerous applications. To my knowledge, personal human-powered aircraft – the one you seem to find ridiculous – is not one of them.Creating a structure strong enough for flight but light enough for a human to power requires you to completely rethink how aircraft are designed. The know-how and techniques that made this flight possible are incredibly promising for improving the efficiency and strength of conventional aircraft.

Someone like Lance Armstrong may be able to fly it for 10 minutes, which is enough to get across a gator infested moat.

    Meh. This really can’t be called a helicopter. More like a hovercraft. The ground is what keeps it up. Go a few feet higher and it’s worthless.

    That’s not a helicopter, that’s a ground effect vehicle. It would never get more than a few feet off the ground on that power, once you got above ground effect.

    Someone needs to teach these folks about ground effect. It’s off the ground, but not really flying. Well I guess in a way it is, but in a way so is jumping and throwing a ball.

    *Adjusts glasses* According to my calculations…power density required: w = sqrt((g^3 *M) / (rho*A)) [W/kg]M = total system mass [kg]g = gravitational constant [9.81 m/s2]rho = air density [1.20 kg/m3]So assuming you can create a craft large enough with limited human power density, it should be totally possible. Just about getting it to a size where specific lift energy is low enough…

    Daily Do-Dad: June 25th, 2012Gamera 2Last summer a team from the Clark School of Engineering at the University of Maryland created a human-powered helicopter called Gamera, and managed to get it off the ground for 11 seconds. Last year’s Gamera was pretty amazing, but the Gamera II has been improved in many ways. It’s 105 feet across, and each of the four rotors are 42 feet long. For all that, it weighs only 71 pounds, which is 30 pounds lighter than last year’s model. Thank you, carbon fiber. The engine is a single human who uses both foot and hand pedals.Gamera II HPH World Record Flight: 50 seconds#hover #fly #helicopter #gameraii #worldrecord #june25

    My guess is that the craft was designed to take advantage of the ground effect, as others have mentioned. So a tri or quad rotor configuration was the only way to get the blades close enough to the ground to do this. A single blade sitting atop the cockpit wouldn’t be able to take advantage of the ground effect. The idea here is just to get the craft off the ground. Some other configuration will be needed for the height record.

    Good example of a rotating wings in ground effect. ANY chance at it being able to get to 3 meters to get the prize? There was a human powered plane that flew helped by the ground effect before the gossamer albatross. It couldn’t make the hop to 3 meters to get the prize.Good luck tho om the 3 meter hop, and staying in the 20 meter square.

    However I think ground effect plays a big part here, helps get it off the ground, but then not much higher. That will be the next challenge: More height and directional control.Great work so far though
