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.

A perfect glider, a perfect pilot, ... and a helpful groundeffect! Welldone!

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

Perfect conditions + epic design. Superb!

Great job..very well done! 👍

Excellent design, good launch. Good flight by a trained pilot. Good crew.

So amazing and impressive. A massive achievement.

very nice, neatly flown. also not to forget the builders, well done! respect! Greetings from the Netherlands! Rob

Her tension at the launch was so palpable yet positive. Love it when the pilot/aviator utters 'This is fun!" :)

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.

Wow,amazing team support

Wow that's a long glide over such a low altitude.

@@user-ft8fl2nl3w 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.

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

@TDOBrandano

Жыл бұрын

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.

着水後まできれいでした。

I have an idea for a launching system that would send that plain to the stratos.

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!!!

@delboy1727

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.

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?

@qian333

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.
