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?
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.
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
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"
Amazing glide ratio! They took advantage of ground effect too

@@thedave7760 that is an incredible thought! Especially if they had a Bimini Top.

@@DoNotPushHere correct, off the windscreen.
So impressive. Respect given to this team! They have obviously worked hard to earn and deserve a very well done❤️💯
Absolutely brilliant. She was such a cool pilot. Very well done. Congratulations on an epic feat.
A perfect glider, a perfect pilot, ... and a helpful groundeffect! Welldone!
Perfect conditions + epic design. Superb!
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）.

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.

母校の活躍、純粋に嬉しい
ナウシカのメーヴェみたいでかっこよすぎる！
まさに実写版ナウシカ！！ナウシカのBGM聞きながら画像見たらカッコよさ感動倍増！！
Excellent design, good launch. Good flight by a trained pilot. Good crew.
That is incredible! Spectacular achievement. Huge respect for the whole team, particularly the pilot. She did a simply sensational job.
,
Almost half a kilometer. Insane.
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!" :)
AMAZING!!! A wonderful design and EXCELLENT engineering. Well done!!!

Beautiful wow 🎉🎉 that was awesome 👌 👏 👍
Flite test let's see if you can break this record! Amazing flight, congratulations!
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.
Dumont manda . Parabéns .....uma incrível distância percorrida ...
桜さんかわいいなー！
Bravo, excellent, belle machine et bon pilote 😀
So amazing and impressive. A massive achievement.
Wow that's a long glide over such a low altitude.
Thanks thats Brilliant!! Congratulations!! 🎉🎉🎉🎉🎉.
Very good. First nose down, get some safe speed. And then leveling out, and go for a max. stall at the end... Not too much steering, to slow it down.
Great job..very well done! 👍
Looks like that camera boat might have caused the starboard wing to stall @3:23 Beautiful flight nonetheless.
What a spectacular achievement by the whole team. 🙏🙏🇬🇧🇮🇳
Increíble, felicitaciones desde Argentina!
絶対こいつらのカードの暗証番号451やろうな
その発想😂
いいね！気持ち良さそう
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.
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。

nice 60 km ,amazing team support
0:27 桂さんって東北大ウインドノーツOBの？
I like these gliders better than the pedal plane competitions!
Are those boats helping to generate lift by creating up-currents?
Wow, that was very impressive.
Amazing. Now where is the YF-19?
Phantastische Leistung der Erbauer und sehr gute Leistung der Pilotin meinen grossen Respekt an die Mannschaft !!!!!
Fantastic job, well deserved🥳
Brilliant engineering. Congratulations.😂
❤ wonderful effort congratulations 🎉🎉
Great bit of engineering.
Best Flutog ever.
Meus parabéns...

レッドブルはあれが良いんだよ。
Brilliant. Well done.
Where does this competition take place????
3:32, that looks terrifying as hell, with water quickly filling up the cockpit. I wonder how she got out so quick'
Amazing! Now improve the structure and add controls and they will have a beautiful aircraft
最高の鳥になった🎵 よくやったね😊😊😊
Beutifull. Good work
Imagine doing this with a controllable glider on a slope with this glideratio.
Even with the slightest wind breeze it stays airborn for days
fantastisch!👍👍👍👍👍❤️❤️❤️❤️❤️ Gruß aus Deutschland!

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
Congrats Guys....fantastic
awesome, well done all around
doesnt even compare to the red bull contest
Holy shit. That's seriously impressive.
Now strap a pair of little EDFs to it to keep it going further!

Education and discipline my friend
Incredible job team!
I believe the only control she had was moving CG forward and afterwards moving her body.
My goodness the Japanese take bird man rally seriously. Think in Australia they attain something like 10 metre's. Big congrats to japanese.
着水後まできれいでした。
Absolutely amazing 👍
Wow,amazing team support
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.
Excellent!!!
Very impressive. Congratulations. 👍😁🇦🇺
WOW....this is very impressive❤
That was great!
Fantastischer Flug 👍👌
機体が美しい
The magic of ground effect!
Most Excellent!!!
Fantastic flight! Well done indeed...
I knew it would got far but that was incredible! Wish I knew Japanese.
How far did she fly? I didn’t understand what they said
Thats awesome 👏👏👏👏👏👏👏
すげぇ
Wow! Super impressive achievement.
Very impressive next time off the top of a mountain
Lindo lindo lindo, parabéns!
Put a electric motor on it ..
Wow... that's cool 😎
สุดยอด ไปได้ไกลมาก
Impressive job!
SO cool!
Fantastic achievement!!!
A tiny head wind breeze, and she could have gone to the end of the bay.
Even in America this is cool
That was unbelievable.
Fantastic...hi...from india...state tamilnadu...
Very nice result! Impressive
alucinante!👍🏿✊🏿✊🏿✊🏿
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.
泣ける😂
