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.

  1. hshs, cool stuff, looks interesting, but long flights won’t be possible, good for obese people to exercise and loose some wright and get fit too.

  2. Ground effect is NOT a force which can be used like you suggest. Ground effect actually is the single thing hurting him. It is harder to fly because of ground effect.

  4. That’s a cool project!!it people like you who try different things who can really say they’ve livedGood work

  5. You lost for being dumb enough to take that comment serious & make that dumbass reply

  6. Prove to me that it’s fake. Why do you think it’s fake. Don’t you think it’s possible? Where did you get your fucking aeronautical engineering degree (from a young earth creationists website). How do you fucking know?

  7. Bullshit!I bet you couldn’t take-off from the ground under you own power and fly for any longer than one-tenth of a second (only jump) with a bed-sheet. 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.

  8. The difference here is that if you attach blades to the edges of your grandma’s bed sheet it doesn’t become a totally sweet (if impossible/implausible) zombie area-attack weapon.

  9. 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.

  12. P51 Fave Link: „A human powered helicopter built by students from the University of Maryland and piloted by Kyle Gluesenkamp set a new world record of 50 seconds! This flight was over twice as long as the previous world record of 19.4 seconds by Akira Naito in 1994.“

  13. imagine this with an electric motor and perhaps pedal assist witht he right gearing so to keep up with the motor rpm. I think electric pedal assist is what we should concentrate on. I have figured human power alone won’t do it but i could be wrong.

  14. Is it using some kind of gyro control of the rotor pitch to control attitude, or are there people holding it stable?

  15. would be nice to see an original idea, not a Yuri II replica (i know it’s probably structured differently etc), well done all the same.

  16. you spend more than thousands of dollars just to lift that thing 5 inches from than ground…oh well,anyways that seems to be a good cardio work out …

  18. Ground effect is real. But since this ship have HUGE wings (rotating wings), the ground effect will be felt up to a few meters, so they might achieve their goal!

  19. Sorry, you read it wrong. I was replying to another comment, about the comparison with regular bicycles. Sitting bikes are “very inefficient in terms of aerodynamic and human energy use.”. The second part of my comment is about the “sitting position” used for this purpose, which looks very adequate!

  21. You obviously have no clue what kind of engineering went into that thing. It is, in fact, the most aerodynamically and energy-use-wise human powered helicopter ever in existence. If they wanted to power it from about a dozen laptop batteries, it could stay aloft for an hour.

  23. it did fly, and it did beautifully. A “ground effect” is a feeling, an experience felt by humans, an effect, not an actually incident; you should probably read more about “ground effect”! 🙂

  28. it woultn’t fly to any hight above 1 meter…air pressure above ground is bigger….if it would fly even 50cm higher, pressure would decrease….so that’s why it didn’t continue in rising up:…..the same with high speed pc fans….it would rise few milimeters above ground but that’s all…..ground effect

  30. They should have positioned the hand crank lower. Circulation of blood is reduced in the current position (for that pilot) so the arms will tire very quicklly. I would also suggest a horizontal configuration using a pulley and such that a rowing action can be used .. But that may add to the complexity and weight.

  32. Look, it’s flying… is it a bird? Is it a plane ?? No it’s the “make you extremely tired in 50 seconds and barely hover at 5 cm above the ground flying aparatus and a very tired cyclist”

  33. What’s up with all the hateful reactions? The Dwights’ brothers first plane didn’t last that long either. These students build the future! Thanks to inventions like this one here, we could be flying our own 1 person-helicopters. Give them some support folks!

  34. If you have not considered it or tried it you might. All it would take is to have a custom wheel made for the one without cranks on it. I have two reasons to believe this would help. 1 it will help sustain rpm and 2 it will keep the rider from having choppy pedal strokes giving a pulse like response to the machine. Think about it try it.

  36. Hmmm… this is nothing new, in fact, Fred Flintstone and Barney Rubble flew a much simpler and more affective peddle powered copter back in the stone ages for a very long time as I recall.

  37. Blade propulsion, the least energy efficient method of flight.Balloons are efficient in terms of energy (buoyancy lift), but waste space in terms of square footage.Jets are fastest, but burn fuel at rates far exceeding blade propulsion.A flywheel powering a generator/battery combo would yield stable temporary energy if powering buoyancy liftoff sources plus blade propulsion for lateral movement.”Powered Parachute” flight is highest in efficiency, but can fail fatally in cross winds.

  38. Chuck Norris would jump up, kick at the Earth to get it spinning and stop where he wanted to land, after the Earth spun around the number of times that he decided was enough.

  39. 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.

  40. If, as I expect, this is in large part a course study project, I applaud those who dreamed up this endeavour as the student target. 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.

  41. Great job Team Gamera. Someone noted that arms and legs are only good for about 500 watts. I have produced over 800 watts and I’m not at peak fitness. 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.

  42. Gamera II is the second human powered helicopter from the University of Maryland’s Alfred Gessow Rotorcraft Center. Video evidence suggests the helicopter, piloted by Kyle Gluesenkamp, flew for 50 seconds!

  43. Further, it is impossible to predict the ways in which this kind of thing can ultimately benefit mankind, unless you are God. Many human achievements and new technologies (even those thought to be purely academic) benefited mankind in ways that remained unidentified until long after the achievement.

  44. They are benefiting mankind merely by pursuing something peaceful and not participating in the kind of sports and entertainment that are indeed currently destroying mankind. They are generating interest in something that is noble and non-violent. They are working as a team to ignite the imagination of millions of people with their pursuit of the Sikorsky Prize.

  45. As an avid cyclist, the ergonomics of any pedal-driven device can make a huge difference in output efficiency. With some tweaks I think U of M team can easily get to the 60 second mark. Congrats on the great show!

  46. and the wrong weight, he would be too heavy and it would get altitude. Look at the guys build in the video and how high he got at that body weight.

  48. OK, this is a marvel in engineering, and not many people could do this, but to be honest, he’s not really flying, he’s creating lift by ground effect, vs real flight propulsion. Still impressive tho!

  49. Yes thanks for the info Ive seen it a while ago it is amazing achievement; as for this machine and timing I rather think it’s too overrated. Description ” flew for 50 seconds! ” Have a good day.

  50. How wonderful !! As science wil come up with even lichter and stronger materials; the sky wil no longer be the limit!! And as all trolls that only can come up with negative dribble on all these videos of marvalous scientific breakthrougs will hopfully kill themselfs soon (the only positive thing they could do) The surviving good fibe will push science to even bigger milestones.

  51. 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.

  53. LOL true… this weakling dude… probably study and gaming all days…they probably picked him because he is the most prominent in the group. 50 seconds record for human flight, wow that’s pathetic..

  54. My research has gone beyond anything I’ve seen or ever heard of online. I’ve figured out that a prop system involving a 90 degree angle of attack in a linear motion with two plate-shaped props can have an 80% efficiency of motor HP input to /liftthrust HP output. 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.

  58. this thing flies more like a hovercraft than a helicopter… hover in ground effect is nothing compared to actual hover.but great achievement nonetheless

  59. You are so full of shit, it hurts. First of all, it’s not strong enough- it’s already broken with minimal use; it’s a fragile piece of shit that’s not going to ever be practical for human-powered flight as otherwise it will be too heavy for that. Second- it is utterly USELESS for conventional aircraft, as it relies almost exclusively on an extreme ground effect and has no use for anything that needs to go more than two feet off the ground.

  61. 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.

  62. Oh, the definition of a helicopter. How about the definition of the word “Practical”? The best designs are the simplest, but they are also ones that work and are practical. If you are going to have something controlled by “brain waves” which is a ridiculous idea, then you are going to need computers, and that means a parasitic generator for the electricity to run the generator or the added weight of solar panels, servo motors etc.. anyone can design something impractical and useless like this…

  63. I’ll bet you’ve never designed or built anything in your life. The definition of helicopter incorporates none of the things you claim it does. As far as I’m concerned, this is a helicopter. In the future, a control system for moving forward and turning by slowing 1 or 2 rotors based on something that uses brain waves can probably be implemented with very little weight cost. Someone like Lance Armstrong may be able to fly it for 10 minutes, which is enough to get across a gator infested moat.

  64. How is that a helicopter? I would call it a hovering platform at best. Does nothing but go up and down. When someone builds one that can go up, the pilot can turn it and travel in any direction they choose, then you will have a helicopter. This thing does not even look like it would have any stability to stay upright or do anything in a breeze but get torn apart.

  67. With the right fuel, you can always do what you want… Neil Armstrong could have written this quote.

  68. An upright cyclist can shift his bodyweight from pedal to pedal thus working with gravity to drive the pedals–especially in sprints and climbs while standing (not seated). A recumbant cyclist relies solely on power derived through muscular contraction. The hand pedals are not going to help either since the limiting factor is the work capacity of the cyclist. The extra set of gears and pedals just add weight.

  70. Nice!… it is not flying yet, but just floating because of ground effect. If you put him up 10feet, it will still drop to the ground. But this is good advancement, we want to see more!

  71. In the future airliners will ask passengers to pedal for them, they are the new efficient and green air crafts of the 22nd Century.

  72. Do you honestly expect these same people to have ever even heard the word derision, let alone understand its meaning? I agree with you btw, but you probably figured that out by now 🙂 Cheers mate.

  74. The only reason it’s flying at all is ground effect, which provides stabilization and extra lift.

  75. How a professional biker sits is limited by the equipment he has to use, for example recumbent bicycles are illegal, and by the fact that professional cyclists cannot use their arms to power their vehicles.

  76. Мечтать! Летать! И думать о прекрасном! Во сне касаться звезд и облаков! И верить в то, что это не напрасно, что в жизни нашей будет любовь! Надеяться на Чудо, верить в Сказку! Любить друг друга, и тепло дарить! И жить по настоящему, без маски. Смеяться. Плакать. И судьбу творить! Дарить друг другу радость и улыбку. От счастья плакать, от любви пылать! И не бояться совершать ошибку. Весь опыт жизни в мудрость превращать!

  77. You have to start somewhere and all advanced technologies start with simple tests that don’t seem significant on their own. But in the totality of everything, down the road this might be the catalyst of something great

  78. So what’s the point of all that? No controls at all, just brute power. Well there is one good point actually it’s a good exercise highly recommend to all the americans, most of whom won’t last even 10 seconds -)

  79. I can see a human powered helicopter achieving the 60 second mark but the height requirement of the Sikorsky Prize is going to take, I imagine, an order of magnitude improvement in design.

  85. Toward the advancement of aeronautical engineering. I’m no engineer, but I do understand that learning to build lighter aircraft (or helicopters, in this case) that require less energy to power will ultimately lead to more efficient aircrafts — less fuel, pollution and dollars. The vehicle in the video is just a stepping stone in the process. It’s not expected to be practical.These kids and others like them are the best hope of American ingenuity. They should be applauded, not ridiculed.

  86. …implying they aren’t TRUE. Tell us then, how it could ever get past even two feet off the ground, that which it requires such close proximity to in order to work well at all? Hmmm?

  87. these comments are ridiculous.i find them juvenile observations meant solely for derision ..like a bully at the clay table in kindergarten… .

  88. 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.

  89. 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.

  90. 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.

  91. *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…

  92. Wish they’d have uploaded a version with proper audio narration and not all this noise. Already watching your video, I gotta *read* about this to figure out what’s going on? No thxtl;dr: Pedal powered heli 50 seconds. omg.

  93. Remember Da Vinci’s drawing of a concept for a helicopter? It was in the form of a spiral screw. 500 years later, man powered helicopters take flight.

  100. I was expecting it to be a bit smaller… make this electric, give it a nice pod to protect you and make it waterproof and we have water walkers 😀

  101. 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.

  102. 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.

  103. 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

  104. para com isso, de que material isso é feito? papel? porque precisa ser incrivelmente leve para ele conseguir voar, com apenas essa velocidade das elices.

  105. OK, so it might not be the most convenient of transports… but why does this not have more views?

  106. Record-setting 50-second flight of the human powered helicopter, Gamera II, from University of Maryland! Piloted by Kyle Gluesenkamp. Shout out to pilot Colin Gore who also flew for 49.2 seconds right afterwards! #gamera
