If the two chase boats had stayed just under each wing it would have gone on forever kind of like a moving wave. that's how efficient this aircraft is. Wow.
@@thedave7760 Probably they are forbidden from doing so, but if it was allowed maybe they could just add a large deflector plate to one of the boats and make the largest walkalong glider ever. Essentially slope soaring on a moving slope.
@@tylerrandolph6193 what is a Bimini top? Thank you! Edit: I assume that you mean one of those fabric canopies, right? But it would need to be slanted to make the standing wave, right?
Oh. My. Goodness, congratulations to the whole team, what a wonderfully splendid achievement. I watched all 451 graceful meters with a huge grin upon my face
Impressive! Beautiful sailplane. Beautiful, graceful glide. Congratulations! Now that I know it glided 451.12 m, please tell me how high above the water surface was the launch?
@@tmt-q6d Thank you for your response. I appreciate it. So, if the sailplane leaves the ramp some 10 m above the surface of the water, then it follows its average Lift-over-Drag ratio (L/D) is about 45.1. And that is pretty darn good for a sailplane. Makes this effort even more impressive. Congratulations and best wishes.
@@dr.gudmundssonaircraftdesign Add another 1.5 m or so for how high the plane was carried. Still, that's a damn good ratio. The best gliders are a tad above 60 today.
Time to bust open Flugtag! Awesome achievement. Other than a tiny bit of weight displacement, it looks like the pilot had no control inputs. Very stable design! Cheers from Sydney - Dave
I think the pilot controls pitch by weight shifting, and maybe they have some rudder control via pedals. The wing curve will easily give you roll control with rudder only, but as long as the flight path is straight enough adding rudder control might just add complexity and drag. I also think that the wingspan is too large for the Flugtag rules, so the record there will require some other design approach.
@@TDOBrandano Thanks for your response. Looks like quite an achievement to me. I was a PPL some years back but now enjoy RC. May get back into flying - including gliders - in the next few years. My son is mad about planes and will begin learning to fly in a DA40 next year. Clearly you're an aviator too! Cheers and thanks - David
For some perspective - this is a video from 2021, with an amazing result. It was recently (2023) beaten at the same place with a similar shaped glider to a little over 500m. The platform height is 10m, that would imply these gliders have a staggering glide ratio of 1:50. The best commercial gliders max out at about 1:44. (this attempt's glide ratio is 1:45). . Overall well done in pushing glide technology forward!!!
Actually the glide ratio of the best commercial glider is around 1:70, and that isn't taking account of ground effect, which obviously benefitted the effort shown in this video.
@@delboy1727I was going to say, with such a wingspan that glider spent *most* of the flight in ground effect. It would take a lot more calculating to determine its glide ratio than simply distance divided by height. Still an interesting craft. I would love to see its true performance with a much higher launch and significantly longer out-of-ground effect flight.
@@delboy1727 The top 'commercial' glider is the JS3 with a glide ratio of 1:55. Never heard of any commercial glider with a 1:70 ratio..... I'm a glider pilot in the market for a glider... I'd gladly save more money and buy a 1:70 ratio instead.... if such a beast existed.
@@markplain2555 OK, maybe not commercial, but a glider does exist that is close to 70:1 glide ratio, though from other commetns I believe it is a prototype. My original comment was meant to dispel the comment that 'commercial' gliders max out at 44:1, which is clearly not true.
Meus parabéns... Vocês tem de participar, com está aeronave, no Redbull... Congratulations... You have to participate, with this aircraft, in Redbull...
Молодец девочка,но могла бы ещё чуть дальше пролететь. Перед посадкой, она начала назад сдвигаться,чего не надо было делать. Планер потерял скорость и спарашутировал, то есть плюхнулся. А так,в общем, команда молодцы,а пилот , вообще красава. Удачи вам во всём.
Congratulations on your great record. However, it is surprising that Japanese people still protect with masks, when overseas peoples already forget about the coronavirus.
What make you think masks are solely about coronavirus? Japanese people are polite to the point that they wear a mask when they suspect they might have a respiratory infection of any kind, even a common cold, just to not inconvenience other members of their society by exposing them to this infection. It's not like "my body, my freedom, my choice to be whatever asshole I want to be" but rather "I won't be a nuisance to you"
i wonder why they dont build a small curve to the downside on the edge of the wing? so the wind can push the plane upwards? a small curve or a bit curve downward on the edge back of the wing?
There is no energy source to support the rise. You will sacrifice speed to allow the rise. The only strategy here is to use the energy of dropping height as much as possible to battle the wind resistance at the most efficient speed.
Look at the arifoil shape of the wing, all the right stuff is done there. The wing is alway pushing upwards otherwise the glider would accelerate downwards wouldn't it..?
Amazing glide ratio! They took advantage of ground effect too
If the two chase boats had stayed just under each wing it would have gone on forever kind of like a moving wave. that's how efficient this aircraft is. Wow.
@@thedave7760 that is an incredible thought! Especially if they had a Bimini Top.

A perfect glider, a perfect pilot, ... and a helpful groundeffect! Welldone!
That is incredible! Spectacular achievement. Huge respect for the whole team, particularly the pilot. She did a simply sensational job.

Impressive! Beautiful sailplane. Beautiful, graceful glide. Congratulations! Now that I know it glided 451.12 m, please tell me how high above the water surface was the launch?
The slope is 10m from the water, 10m runway, and 3.5 degree slope（down slope）.

@@dr.gudmundssonaircraftdesign Add another 1.5 m or so for how high the plane was carried. Still, that's a damn good ratio. The best gliders are a tad above 60 today.
Even the highest quality gliders will not be able to achieve a glide ratio of 60 in this competition where the initial speed is low.
very nice, neatly flown.
also not to forget the builders, well done! respect!
Greetings from the Netherlands!

Her tension at the launch was so palpable yet positive. Love it when the pilot/aviator utters 'This is fun!" :)
Excellent design, good launch. Good flight by a trained pilot. Good crew.
Beautiful wow 🎉🎉 that was awesome 👌 👏 👍

Guys that participate in flugtag are veeeery behind from this
flugtag has more rules as per max wing span and length, this glider would not be allowed to participate.
Great job..very well done! 👍
What a spectacular achievement by the whole team. 🙏🙏🇬🇧🇮🇳
Fantástico!!! Abraço do Brasil!! Curtindo e acompanhando!
Increíble, felicitaciones desde Argentina!
桜さんかわいいなー！
So amazing and impressive. A massive achievement.
絶対こいつらのカードの暗証番号451やろうな

いいね！気持ち良さそう
Dumont manda . Parabéns .....uma incrível distância percorrida ...
nice 60 km ,amazing team support
Amazing. I just wonder if those boats to the left n right didn't disrupt the ground effects of the air flow being that close to the tips of the wings.
Best Flutog ever.
Looks like that camera boat might have caused the starboard wing to stall @3:23 Beautiful flight nonetheless.
Fantastic job, well deserved🥳
Great bit of engineering.
私は一応ここの半世紀前の卒業生なんだけれど。
今の都立大女子はこんなことをやるのか。ただただ驚いた。
Wow, that was very impressive.
I like these gliders better than the pedal plane competitions!
Brilliant. Well done.
well made glider!! well done!! amazing glide distance.
Amazing. Now where is the YF-19?
❤ wonderful effort congratulations 🎉🎉
fantastisch!👍👍👍👍👍❤️❤️❤️❤️❤️ Gruß aus Deutschland!
Imagine doing this with a controllable glider on a slope with this glideratio.
Even with the slightest wind breeze it stays airborn for days
Casi 1/2 Km. Felicidades. Ustedes si son personas dedicadas. Red Bull Flugtag no ha llegado ni a 50 metros.
creo q el flutag es para borrachos con talento, nada mas
Incredible job team!
Very impressive.
Excellent!!!
That was great!
Beutifull. Good work

Congrats Guys....fantastic
Where does this competition take place????
Amazing! Now improve the structure and add controls and they will have a beautiful aircraft
Brilliant engineering. Congratulations.😂
Wow,amazing team support
最高の鳥になった🎵 よくやったね😊😊😊
Absolutely amazing 👍
Phantastische Leistung der Erbauer und sehr gute Leistung der Pilotin meinen grossen Respekt an die Mannschaft !!!!!
3:32, that looks terrifying as hell, with water quickly filling up the cockpit. I wonder how she got out so quick'
Most Excellent!!!
WOW....this is very impressive❤
My goodness the Japanese take bird man rally seriously. Think in Australia they attain something like 10 metre's. Big congrats to japanese.
Very impressive. Congratulations. 👍😁🇦🇺

Fantastic flight! Well done indeed...
Holy shit. That's seriously impressive.
Now strap a pair of little EDFs to it to keep it going further!
Thats awesome 👏👏👏👏👏👏👏
awesome, well done all around
doesnt even compare to the red bull contest
The magic of ground effect!
Wow! Super impressive achievement.
What a result. Where can I find out more about this aircraft and how far they flew?
watch all the video, it tells you how far.
451.12 meters and that is pretty far, well done team
Complimenti dall'Italia...!
It's the summer event every year in Japan, including man powered aircraft.
Fantastischer Flug 👍👌
Impressive job!
SO cool!
I believe the only control she had was moving CG forward and afterwards moving her body.

Put a electric motor on it ..
Wow... that's cool 😎
I knew it would got far but that was incredible! Wish I knew Japanese.

Very impressive next time off the top of a mountain
Even in America this is cool
That was unbelievable.

Curves are drag... drag on gliders are not okay. Like said above me, no engine to turn that into lift.
RESPECT
Why didn't they add a bycicle driven propeller to keep pushing the glider?
There is a glider section and a human-powered propeller section.
