Ekranoplans: Autonomously Expanding the Limits 

Ballsy move in a glider, a bit of wing flex and that sh*t can go real wrong

Even noticeable in a hang-glider when the wing is a couple metres from the ground.

@@afrog2666 Wing flex? What are you talking about? Glider aerobatic demonstrations rely hugely on ground effect.

GIGACHAD HOLY

@@thefirstsin what ?

Learn to hang-glide !?

thanks for the tip, on order...

Here is the one good model developed back in 1987 en.wikipedia.org/wiki/Lun-class_ekranoplan

@@sergouss I was there this summer, saw that soviet monster with my eyes and almost cried of his unlucky fate. Hope someone will continue the history of экранопланs Btw "экран" means "shield", in this case its air shield / buffer

What they are doing is an absolute beauty !

I think that’s what we all love about rctestflight!

Well, the USSR developed real ekranoplans in 1975 GEV

If he can build a full size WIG craft that can carry 8-10 passengers and navigate over 5'-10ft seas it will overfly all the current WIG craft I've seen fly.

Is the concept all in your head, as I couldn't see anything on your channel?

@@ruzziasht349 no no it was part of my masters thesis

At this scale? You mean tiny little teeny toy scale? What was your model, only drawn on paper?

are you guys fucking high...you did your masters thesis on a concept thats already full scaled in production? ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--r7mFSq8PRU.html

I found it a bit odd that 'the company' gave them pretty much open ended design freedom, and sounds like they came up with the design!!!?? So the company, that's been working on this for some time, didn't even have a concept design????

@@pawspaws101 it has. This configuration of an inverse delta in ground effect is very old, first designed by Prof. Lippisch in the early 60's and first "flown" in 1963. It was subsequently developed into larger more capable (prototype) models that culminated in the design of the company talked about here.

No way that is amazing that you met him! I'm jealous!

Awesome!

yea pretty much. if your designing and making their test model

yea no kidding... highly doubt they paid them even close to enough, akin to "i can trade you for exposure"

Pete sripol made one

I checked your channel, you have nothing.

@@ruzziasht349 I never said I made videos I said I've been make RC WIG vehicles for years.

@@willowehrich6207 It's much, much easier to make a video (to prove what you've been doing), than to make and an actual WIG vehicle.

It is also how most big birds can slow down to a few km/h before landing

I mean - noticing the effect is basically guaranteed - any aircraft that has fixed wings will experience it during takeoff and landing.

@@tofaanshinwari6431 Nobody wants that bullshit here.

@@ABaumstumpf Yes, but WIG craft are specifically designed to fly in the effect efficiently.

Supernice edited and music as well!

Let's hope modern Americans aren't too afraid of Russia to embrace the technology they pioneered decades ago ... 😂

Yeah, and once you realize this would never work at full scale, you realize it is a huge fail.

@@VidarrKerr this does work at full scale. I don’t understand your comment.

@@toxaq Bro, it is a tiny little model plane. That is NOT full scale.

@@VidarrKerr I'm aware as I watched the video. I've asked for data to see how useful the effect is at this scale. You stated "this would never work at full scale". I don't understand how you could state this as there are plenty of ground effects vehicles at full scale. So I'm wondering what you meant by your comment.

@@VidarrKerr You do realize ekranoplans get better the bigger they are right? both in efficiency and in stability

I hope it gets added too.

I don't have plans to share for the first one, this one is completely different in every way though. You should go for it, these things are a hoot.

@@thinkflight would you be willing to send me the airframe if I cover freight charges? Or let me know how much you would need to part ways with the airframe and onboard electronics (receiver, servos, anything that might difficult or help impossible to remove. ) you I have a selection of autopilots, sensors, batteries, and transmitters. I’m an electronics engineer and embedded systems designer/programmer. I just don’t have mad fabrication skills you’ve demonstrated, though you have inspired me to develop those skills over time. Best wishes and keep up the good work!

Canards are pretty unstable and how would it perform if it was in ground effect?

The reverse delta already is one of the more stable forms for ground-effect, but with small aircrafts you really want the extra stability that comes from the surface that is further away from the ground. Canards would like have a similar problem as the wings - their effect would vary greatly depending on how close to the ground it is.

I am honored Alexandre, gratitude.

Yes drag goes down so efficiency goes up. Can't give you numbers though

@@Veikra i am expected efficiency to go up. Id like to know by how much. Ground effect craft are kinda niche market and need to prove a lot if they are going to catch on.

Yeah I'd like them to run a few battery tests at least, one flying it as a plane, and another at ground effect and use flight times as a metric for efficiency.

@@bucklogos exactly!

Yeah, and waves doesn't scale, those were som mountains if you take scale into it. On a fullsize craft the waves are more like ripples in the ground

@@someoneelse7629 I would say that survivability gets worse with increased scale because the length, area, volume, strength, mass, velocity & Rn ratios involved in scaling, full size things tend to be more fragile for their size than models.

ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ifllgTA2pmY.html"!"

In larger aircraft, independent canards controlled by electronics would be the most likely candidate to take the place of throttle modulation for a more direct attitude control, while the elevator would be used for more traditional attitude changes. Minor correction would really be all that you'd need, and that can be accomplished with canards no problem. Larger aircraft have a tendency to be a bit more stable as well, perhaps not the best use of the word in this case (not as sensitive?), but flight path and attitude changes can be made more gradual without microsecond adjustments due to inertia and momentum. A quick youtube search of Kevin Quinn's waterski record, or any video of an ag plane spraying a field illustrates how stable they are without any sort of attitude control beyond pilot input in comparison to small RC sized aircraft. Even with a good 6-axis gyro/accelerometer, most RC planes can barely approach that level of smooth flying even with a good pilot, and it took considerable effort to design a system that works as well as the plane in this video.

I would love to see this data. Once in ground effect mod the increase lift would require much less propeller push. I would guess is a trade of speed x efficiency in this condition.

The optimal height depends on the size of the airplane and I suppose some other factors but the Caspian Sea Monster hat an optimal ground effect at 20m height.

@@Garium87 "The optimal height depends on the size of the airplane" Yes, hence why i said that downscaling has serious problems as you need to get closer and closer to the surface to get noticeable results, getting ever closer to the wave-tops.

With scaling down a model the behavior is much more sensitive compared to the full size one. In RC planes and helicopters, the larger the model, the more stable it is, so if anything, this video shows that the full scale one would probably be very easy to control (like you said, a proven design).
