This is great! FYI, talk to your meteorology department about finding good sites to fly. The water is safe.... but often is pure sink in terms of air movement. The sun warms the surrounding land, causing air to rise, but there is never a vacuum at ground level, replacement air needs to come from somewhere. That would be from the lake, which is cooler than the surrounding land. This is why it is often clear skies over lakes. You should either fly over fields during the day for some free lift (and at 1m off the ground there is low risk), or get up early! At 6AM the land is cool and the lake may actually be warmer, providing some lift. Based on the shadows this was filmed near mid-day.
I kind of fail to understand why they would fly over water instead of dry land. Did they think this would provide better motivation for the pilot/human-engine to stay airborne?
In the late 1970s, human powered flight was achieved by the Gossamer Albatross. It flew from the UK coast to the French coast. As for this flight, and looking at the Gossamer Albatross, both being almost of the same design, the main difference is the reclining position of the person here as to the conventional upright position in the GA. Up right the pedaller could muster that last bit of energy much easier.
I just love that sense of adventure & 'go for it' attitude on display here. Hopefully much was learned & the next effort will be even better. Kanazawa is such a lovely part of Japan to conduct this experiment. Well done Japan. Gambate kudasai.
A noticeable improvement is no longer possible. The wing has a huge aspect ratio and is incredibly light, as you can see from the way it follows the swell of the water.

I watched a documentary about 25 years ago where they attempted to recreate the Icarus man-powered flight (myth) and flew about 30 miles from one Greek island to Santorini (if I remember correctly). The guy flew into the sea about 300m short of the beach having flown about 30 miles. It doesn’t appear that much progress has been made since.
@@cyrildanilchenko6776 Thanks. My memory is a bit vague now but it was a huge achievement at the time. In light of all the new materials and technology available now, they seem to have taken a step backwards. However, I don’t really know any details of this project. Maybe they only had a small budget.
Beautifully built aircraft congratulations !!! I am curious why they would fly it over water because water cools the air off and generally speaking. Hang gliders down. If this flight was over a Salt Flat with a hot-air swells happening it would probably stay in the air a lot longer.
Human powered flight means the craft must gain altitude. That was a glider with the human slowing the decent of the craft. Quite a few designs of hyper-light honeycomb 3D printing designs floating around they could use to replace structure members. Decrease mass by 10 to 20 percent could make a big difference.
And the pilot needed the extra weight of a crash helmet why? But this is great. Humans being good, and great and, yes! Why not build a human powered airplane and fly it into the water? That guy in the wetsuit and fins who jumped in off the boat to assist, the boat drivers, the guys and gals who helped run the plane during takeoff. Yes, human beings being great as human beings. Not breaking anything. Not tearing down someone who doesn't look like them or come from their neighborhood. People can be wonderful if they work together and put their minds to it. I love this.
Two questions: 1. Was the lake flight dictated because of a desire to take advantage of ground effect and smooth laminar air flow? 2. Was the lake flight dictated by lack of space elsewhere in Japan? Great video. Thank you. Cheers, D.
The lake is good for the safety reason. This is a human powered aircraft ( just like a bike). So all aircrafts end up landing on water when the pilot stops pedaling to rotate the propellor. Because it’s human powered, the aircraft is designed to be broken properly so the pilot can get out when landing on water. This is a flight efficiently competition among Japanese universities.
219 / 5000 Very nice and beautiful to see, (Beautiful / Great performance!) Congratulations!!! also here I wonder why the wing is so narrow? a little wider maybe more lift? Healthy and Friendly Greetings from the Netherlands! Rob
I actually think this would't apply to a record attempt. Since they start on land, and then go to water, they essentially start higher than they end, adding potential energy. That means part of its distance was achieved through gliding over that vertical distance.
Nose heavy for sure. Over stable. Move the CG aft and he won't have to maintain as much airspeed to fly and reduce drag by not having to constantly adjust his AOA. I was lucky enough to be a spectator of the Gossamer Condor. The first manpowered flight back in the seventies. Strange that we haven't got it figured out after all these years.
@@Txdvsz damn thats fascinating. Do you think perhaps also the propeller is at two high of a tilt? lower angle and higher rpm i think would work better but im sure they have the math to justify the propeller they used.
@@Txdvsz The Gossamer Condor was not the first manpowered aircraft, both the SUMPAC and the Hatfield Puffin preceded it by 16 years and Jupiter was into the air 5 years before the Gossamer Condor.
@@Txdvsz Youi claimed it was simply first, I gave counter examples. No extra requirements. The end. But, by all means, push the goal posts around till they suit you.
@@007floppyboy Or shoulder wings (mid fuselage mount), but it adds complexity. Human powered flight is very difficult. I think it should only count if it leaves the ground effect.
@@007floppyboy The Kremer Prize only required flying over a 10 foot hurdle at the beginning and the end of the flight, but it was not valid for all altitudes - flying the whole course 3 ft above ground would not count.
F'KEN silly comment. How would it land? It's designed to come down on water using it's belly. Also lots of advantages to having the wing above the cockpit, especially clear visibility and a strong design using the wing as a kind of girder, it provides structural integrity. Bloody TH-cam experts, can't appreciate things for what they are.
I think what they need is more tension on the chain that drives the propeller so they can get more turns out of it and make it go a bit faster but not too much tension that the person gets tired out after a few minutes of peddaling
Sorry, why don't you use a variable pitch propeller? It is necessary to optimize the friction of the propeller to manage a pedal stroke and a constant altitude.
Thinking Non water absorbing floats would add only 4 pounds and would keep the cabin on top of the water and not “in” the water. Design them like medical capsules to be wind friendly.
Probably. The pilot probably was only pedaling flat out, it takes a lot of energy to keep a human in the air. A non-professional cyclist can only keep that up for so long.... Still, amazing project, just too bad that every attempt essentially costs them an aircraft.
You should use the same principle in electric bikes, that would be more efficient. Using the legs will help to give necessary trust and increase autonomy.
Makes you appreciate how amazing evolution in nature is making birds and some other animals fly. Mankind dreams of it since the beginning and even after several thousand years of civilization, bringing people to the moon, making it possible to communicate around the globe, and more breathtaking inventions, they still only manage to fly a couple of hundreds of meters on human power alone.
"The current distance record recognised by the FAI was achieved on 23 April 1988 from Iraklion on Crete to Santorini in the MIT Daedalus 88 piloted by Kanellos Kanellopoulos: a straight distance of 115.11 km (71.53 mi)." Source: en.wikipedia.org/wiki/History_of_human-powered_aircraft
It clearly wasn't using ground effect as the speed and angles wouldn't take any advantage of this effect, there's a tiny altitude difference but minimal and water is usable safe space. It's amazing how close you are I think the rigidity is an issue as ur loosing energy but it's obviously very hard to balance, if you could improve the rigidity I think ud get very close to gaining altitude and making a turn. Wish u all the best.
fix the gear box so you have to pedal ALOT LESS like half a pedal rotation to give your propeller 10x the rotation..i can already see this plane flying alot higher alot longer with alot less pedal effort :), very interesting build :)
hah, I'm afraid you have no idea what you're talking about. Do you think that people from an engineering university didn't optimize as much as they could? The propeller is of that size and this rotation speed plainly because it appears that this is the most efficient way to propel the aircraft with very limited power.
Yes. If the altitude was meant to be that low, they should have stayed over land. Only if they intended to fly higher, being over water would be better in case of a crash.
Still lake water guarantees a soft landing for the delicate craft and efficient recovery. There are also significant benefits to flying in ground effect, which can be more difficult in uneven areas. Water is just easier and more predictable to deal with.
Exactly. Air tends to sink over water, and rise over fields. All soaring pilots know this. If you've got plenty of kinetic energy you can fly over a lake or river for a short time, but want to get back over fields or near hills to take advantage of rising currents.
@@OYeahan Water is softer to land on than a dry salt lake bed. Try doing a face plant on water, and then try doing a face plant on a dry salt lake bed, and then report your results back to us.
@@ItsVideos it all depends on speed, but I obviously meant that with little vertical speed and more horizontal speed the deceleration is much less abrupt on a dry salt lake bed, whereas the sinking of parts of the structure provides lots of hydrodynamic drag and leads to structural decomposition (vide airplanes ditching; actually it is safer to crash-land on some long meadow). Maybe less of an issue with those speeds, but as the airframe is extremely fragile, this destructive hydrodynamic breaking effect is demonstrated in this very video.
@@OYeahan ... I stepped though the landing frame by frame. Most of the energy was dissipated by the shell, and the small canard took the rest. The wing tips did not touch the water until the plane had stopped. I see no damage. It wouldn't surprise me if it was immediately airworthy. You call it "destructive" braking without providing any evidence of damage. Your talk about ditching aircraft that weigh thousand of pounds has little relevance here. However, I encourage you to send your ideas and your credentials to the Kanazawa Institute of Technology 😁
Did he try to touch the water and was surprised by breaking effect, so that the aircraft slowed down and was drawn into water? Or was it just so straining that he couldn´t keep the speed up and had to land?
Doesn't the upward curved part of the wings lose its ability to create lift and create unneeded weight? Couldn't the extra weight of wire struts to keep them straight be insignificant?
Was it made out of sugar? The moment it touched the water it got dissolved XD I guess it's for safety reasons so the pilot can easily escape. Well done!
It's called 'Canard ' because you have to pedal fucanard.
LOL!
Excellent.

Easier to find flat water than flat ground in Japan I would imagine.
They are using what is called “ground effect” birds use this often over water
@@zacharyerskine4277 that would technically make this an ekranoplan.
Maybe because they knew the plane would eventually fall down and falling on water would hurt less than impacting the ground
@@InsanitiesBrother How far was that? I am sure there are countless airfields that could have provided that distance.
