It's difficult to build a working four-rotor helicopter that spans 100 feet and only weighs 80 pounds. It's even harder when your engine is a 0.7-horsepower person. But one team of engineering students is trying to do just that.

Your indignation is not righteous 🤣🤣🤣🤣
Honestly, I believe what you guys need isn't an extra engineer but actually an expert in biomechanics. The way the pilots have to work really isn't optimal, especially the arm motion is off.
Exactly
Correct, leaning sitting like a bike would for example be more efficient
Wouldn't that make it harder to lift it? The machine would be significantly heavier with two more pilots.
@@neocyran we shouldn't have 2 pilots... I think you misunderstood this

As amazing as this is, they need a bit of input from someone with some athletic experience in the mix. That ride position is terrible, and the upper crank arms (the ones they grip with their hands) are awkwardly short because of it. The lower crank also shouldn't be directly out in front, but below the operator, like a bicycle. Just fixing those two things, then putting someone with excellent conditioning in the cockpit, would likely get them well over 10' with their current design.

Think 25 speed… my first bike was a 3speed. Then a 10, then a 15 then a 20 that was really fast. Good try, but not even touching 50 year old technology yet. Think faster smaller rotors. More gearing. Smaller = less weight, more speed.
@@krdelux3919 thank you for your thought but those engineering students would have thought of it, if it would make sense, those rotors need to be that big to create strong enough force its allways a fight on weight reduction while maximizing thrust

Can't believe what little motion from the propellers can product such lift. Nice.
I was going to say the same, I think it must be fake.
You have 80 lbs spread over a frame that takes up 100 ft and those propellers are close to 50 ft long, they're producing a lot of lift.

I knew that second guy was going to crash haha he was being too cocky.
McClover No he wasn't, it's just that once the aircraft gained that forward momentum it didn't wouldn't stop going in that general direction, it possibly couldn't.
Ziyad Thunku Ousmand I think the problem is they yell at him to back down when it is basically too late, then it starts dropping too fast.. so yeah its not entirely his fault. They probably need a bigger space to test it in and some padded material to protect it when it crashes. Although to the credit of McClover, had a bad feeling about mustachio as well.. blondie had more respect for the task and showed more control on his run. It makes me wonder when he had such a good run why they had the other yahoo try.. talk about a bad decision
+Arthur Kay I think they yell like it's super bad so he basically like stops the thing
+GremlinFPV The instability you describe is inherent to all rotary wing aircraft, not only quads. Indeed, this one did not have any kind of control and for this reason it lost the competition to another, even larger quadcoopter - the Aerovelo Atlas, which had huge, 20m diameter rotors turning at just 10 RPM and one very important difference: it had control, allowing the pilot to remain inside the assigned area throughout the flight. So the Aerovelo team pocketed US$250,000.
***** No worries, your point came across as well. Happy flying, fellow FPVer! :)
I've been dreaming of this since I was 10. Until Carbon Fiber blades I had little hope but still no feasibility. Great to see someone else is all over it!

Ryan Lockwood Bigger doesn't necessarily mean stronger. There's certainly much stronger people out there that weight even less than these guys.
Lex Someone resurrect Bruce Lee he'll fly to the next planet
The pilot Henry actually helped me buy a bike when he worked at a bike store! It's so cool seeing him do this as I didn't know he was involved:)
As a somewhat competitive amateur cyclist, my lukewarm take is that the hand cranks were a net-negative aspect of the design. Even pedaling for 1 minute at 90-100rpm is a highly aerobic activity so the limiter is getting oxygenated blood to the muscles involved. Hand cranks added the requirement of additional coordination, anaerobic contributions, weight and friction in the drivetrain of the apparatus.
Da vinci APPROVED THIS
If you look closely you will notice smoke and steam rising off the da Vinci machine. So much for man power. If the thing at the bottom was indeed a platform, the man would spin himself off it. His ornicopter, however, could have flown using a man power. It was engineered for movement like climbing a ladder, very efficient. Perhaps better take than this one, as here left goes with left and right goes with right, not the most efficient way of going about it. And I mean this already is awesome, indeed. Not everybody is da Vinci.

They need a bigger room to do it in. Like a legit hangar or Blimp hangar. They are getting limited by their own vortices. The air is cycling down, back up the walls and down from the ceiling. That wind has velocity which is undermining the rotors lift a bit.
The difference between 10ft and 8ft is that he's trying to get out of ground effect, and the power he must generate increases tremendously.
Gear box maybe two or three speeds, maybe even 18 like a bike to more appropriately clear the ground effect. Possibly carbon fiber filaments to control two of the rotors pitch to provide some control.
Jeremy Cook
A gear system would be for "cruising", and they're a long way from that. They need to generate maximum power, which occurs at a fairly high RPM. And every gram of extra weight makes a big difference.
I agree and I believe the distance of the pedal crank is too short for this guy. He's not extending his legs enough for full power capability. Not trying to be critical, they've done an amazing job. Good luck on future attempts! :}

Gravitation pulls us down with 9.8 Newton per kg, so you need an upward force of 9.8 Newton per kg every second to keep floating, which is 9.8 W per kg.
If the total weight is 100 kg then the human needs to output 980 W at 100% efficiency to float, 1225 W at 80% efficiency. Basically even top athletes will feel like puking after flying with this for a minute no matter how well it is designed or built.

As a point of interest William Denny and Brothers Limited, often referred to simply as Denny, was a Scottish shipbuilding company in Dumbarton. They worked on the development of propellers. They had a flying prototype helicopter before the First World War. Development was shelved on the outbreak of the war so they could concentrate on supplying shipping for the war effort, and never restarted afterwards.
4:35 sounds like my boss when I start getting creative
Like when I have a really good idea, tell my boss, he disregards it.. then later on, someone "thinks" of the same idea and its implemented company wide
they're using the same gearing for arms and legs, It would be better o have slower for legs and faster for arms to cater to their max strength outputs
but it would be heavy, and I think they considered that already
Kommentator 123 I would have thought that they would have considered it already but it should only produce a negligible weight increase (max 500g if done right). simply increase the size of the leg gear and reduce the size of the arm ghear to get the ratio and then resize the spindle to maintain the same kinds of rotational speeds.
Could work!
the arms are just lightening the load of the legs. it's the same gearbox for both of them. there are no separate gearboxes, just two inputs.
***** This is not entirely true, the arms are producing torque, just like the legs and while at the moment, they are attached to the same geartrain, what we were discussing was the possibility of changing the gearing ratio for the arms (which just requires changing the size of the arm pedal gear), thus allowing them to bettwer utilise the arm power of the user

I remember asking him one day. "Dude, what happened to your accent?" He was like. "....... Its gone" 😨.
The main difference I see between this helicopter, and the one that beat it, is the Atlas didn't try to reinvent the wheel using a reclining bicycle and a hand wheel. The pilot is kicking forward for 60 seconds, and there's nothing to counteract those forces. They seem to stop when the helicopter starts drifting, not when the pilot gets tired. In hindsight it's pretty easy to see that this design wouldn't keep on target.
None of this was necessary . I drink a Red Bull and I'm good to go
Clearly operating on ground effect, and sliding off of the pressure column causing drift
Indeed.
Would like to see at least basic controlles to help with drift. The draw wheel that pull's the string should be much larger current one looks to be 24/26 inch wheel a 29 inch wheel would take up string just a bit faster and gear up just a bit would make it easier to hold it off the ground but might take a bit more to spool up to get off the ground up date please

Clearly.
@@thomasnygard2246 A tag line (if allowed) would do wonders.
Ground effect. That is why these human-powered helicopters can't fly arbitrarily high. Ground effect happens when the aircraft is very close to the ground, and essentially the air being pushed downwards by the blades hits the ground and reflects back upwards, making it *easier* to fly while at that low height. The effect increases exponentially as you get closer to the ground, which is why these helicopters shoot up off the ground so easily but then lose lift and can't gain more height. The distance off the ground that ground effect takes place is about half the length of a rotor blade. Note how large the blades are on this aircraft. That is helping them try to "cheat" and keep ground effect in play up to the 10 foot height.

Spandex warriors got me good lol
@@LW12386 You spammed all the comments in here? wow how low... I've reported you..
"Do you even lift?" Has now a new meaning
I love how they have no idea what to do when it goes out of bound ... everybody just starts to scream hoping that it will come down and back to its original place by itself :)
Yeah right... why didnt they attach like 4 loose strings to it, so it is held in place if it beginns to drift to far?
@@godmode8687 Because that would violate the rules. Moron.
@@captaindunsel2806 it violates the rules to secure the helicopter while testing it? It sure as fuck doesn't. All they need to do is remove those lines as soon as they are able to fly relatively stable and reach the correct height for their final test.
Seems like you are the fucking moron for not thinking about it at all?
@@godmode8687 let him know GodMode
@@captaindunsel2806 So does drifting. Moron.
I always say that transmissions are the way of effortless force to be able to reach high speeds, so they won't need to pedal that much
In 2013, 33 years after the competition was established, the award was officially declared won when AeroVelo's Atlas human-powered helicopter conducted a flight that met all the requirements of the AHS International competition, and received the $250,000 prize. Wikipedia.
3:24 that guy in the background tho
😂😂😂😂
Lol
Goooooooooool
Yes, there are people in the background, sub-genius.
@@Anthony_in_Bloomington_Indiana *genius. Fixed it for you. If you're gonna make fun of someone, do it right. Amateur.
On 13 June 2013 at 12:43PM EDT, AeroVelo managed to keep its Atlas HPH in the air for 64.11 seconds, reaching a peak altitude of 3.3 meters and drifting no more than 9.8 meters from the starting point. After the AHS International Human Powered Helicopter Competition Committee reviewed the data from the flight, AHS International announced that the flight had met the requirements of the competition and that AeroVelo had officially won.
AHS International awarded the prize on 11 July 2013 to the AeroVelo Atlas.

"You never fail until you stop trying"....Albert Einstein,
Being a mechanical engineer, I can feel your thirst for thrust!
It's reminiscent of those 19th and early 20th century videos we've all seen of failed early flight attempts ... but of course, the engineering on this contraption is quite advanced. I wonder if it would ever have any practical value? And how to stabilize it, so it doesn't drift?
That's all we need - a pack of these cyclists in their spandex and hovercopters hogging the traffic lanes and blowing through stop signs at 1.5 mph.
slow down grandma
Skinny bird- chested men only
you had me at spandex
OMG! Perfect.
fuck you and your gasoline powered vehicle. the man on a bicycle is the most energy efficient animal on earth
Do engineering students in America really use these antiquated "English" units that even the British don't use any more for engineering? "How quaint", as American tourists say when abroad. Even the challenge states 10m must be reached but then they think of heights in the length of an old boot. Hilarious.
Even when the world moves towards the metric system, they will still be using that obsolete imperial system. What can you do? It's just the way it is with them.
Imagine making 318 million people start using metric. Changing millions of road signs and so many other things just to make you happy. That would be quite expensive and not easy.
AJHedges Not to make *me* happy. Or him (or her?). When the world moves to certain direction, which makes sense, the rest must (or at least should) follow.
Of course it's not something that will happen from one day to the other, but they should at least begin by teaching it in their schools.
Ignorant. They have been teaching it for quite some time.
Have they been learning it then? And please keep it civil, I'm being polite with you.
A few decades ago when a group tried to win the prize for powered man flight, AKA Kremer Prize, they had a decent design and then tried powering it with one of their trained glider pilots thinking that piloting skills were critical. What they found was, that the pilot or engineer was not that critical. They ended up recruiting a trained cyclist and he had the horsepower to make the thing work and the won the prize prize. Geeks and brains are necessary but not complete without the brawn
All the hundreds of hours of design, engineering, construction, trial, and error and they praise the monkey who pedals hard like a God. Lol!
keep going, keep going, KEEP PUSHING IT ... BACK DOWN BACK DOWN !!!
4:30 lol
back down colin back down back down back down back down back downnnnnnnn................are you okay ?
12 cameras and no one shot the crash away view of the crash or aftermath?
They had good footage of the crash but then the editor got it. Editor has been watching lots of action movies.
They didn't want to show the crash. The new generation only shows success and a
fairy tale world.
The pilot needs a Red bull. Imagine a Red Bull label on it and the pilot drinking Red Bull while flying.
