So cool! Now it just needs some pitch control so you can fly up out of ground effect 😉
We'll see if weight shift can handle it, if not....
@@thinkflight
Weight shift: no moving parts = better
Control surfaces: have moving parts =less better
@@2ndch. less and sluggish control authority with weight shifting alone.
I agree ! The advantage of having no moving parts is obvious. However, aerodynamic controls act faster and with a bigger range. As an aircrafter I would vote for the pitch control.
@@thinkflight You sound like a true hang glider. KISS.
Have you heard of the flairboat? It's a ground effect vehicle that was made a while ago that had a layout very similar to yours, except it also had fins(?) or a skirt(?) for lack of better word connecting the ends of the front wings to the back wings. Its only control surface was the rudder, and the roll was aerodynamically stable. Perhaps this addition of a skirt might help funnel air under the wings and increase the air pressure to help stability. Also counterintuitively, your craft might be too light and can generate enough lift to leave the ground effect. Maybe extra weight will help keep it in a safe ground effect as well as lowering its center of gravity to make it easier to control. Otherwise, I'm _really_ impressed with what you've been able to accomplish in a simple home shop. Keep up the good work!
That extra weight should be movable front-to-back and controlled by a computer and a level sensor.
@@snekmeseht Don't know about computer controls since we're trying to keep this backyard shop friendly, but definitely agree on movable mass for trimming thr balance in between runs
@@snekmeseht this weight moving should be all directions I think. Not only front to back.
Moreover it should work like feathers on a birds wing. When you look at birds landing they us there feathers to smooth it out. This is also the case with bats. They don't have feathers but a very flexible wing. So maybe some kind of cape like endings on the wings could help?
The inflexible wings are working great at the start, but are a pain in flight. It is intuitive that we gave bat- and superman a cape. 😏😁
@@snekmeseht or maybe just use flaps?
Also need to make the airfoils tiltable.
It looks like you’re making good progress on this project… but the BEST part was seeing the pure joy on your face 😁😉 Congrats on a first successful flight ! 👏🏻 👏🏻 👏🏻 BraVO I say !!
Been waiting for this video! Great Job!
I know you already committed to the tandem wing but that is causing the runaway effect once angle of attack increases beyond what your weight shift can counter. If you were to make a new one or modify this design then a larger rear wing with a smaller wing at the front that has a higher angle of incidence would most likely cure that problem. Same as any Canard aircraft configuration works. The front wing stalls first and drives down the front so the rear never stalls. If done right I imagine it could be towed at varying speeds and be self stabilising. Also I wondered about the choice of that single rear fin behind you, if you were to lose grip on the handle and fall backwards then you'd injure yourself on that fin, maybe think about a twin fin design? Love your ambition and that you go out and build and then fly this thing - keep up the great work you're doing on this channel!
I agree with all of this especially the part about an awesome channel.
The Chariot Ekranoplan!
I love how you simplified everything so much. No complex circuitry and no control surfaces. I love these small ground effect craft, but instead of spending hours retuning code, you just rode it like a chariot!
Yup, you get it!
you should switch to a twin tail and larger tails. your body is blanking out the small current tail. plus if you fall back with a twin tail you fall between the tails. (safety) your upright should be held on with break away pins in case you take a nose dive. there are a few other changes I would make but that should get you going.
What he said!
the upright is foam it will break away ...lol.....
Impossible to hold the craft manuell against the upcomming wing-in-ground effect forces. Learning by doing is not the right way and will become dangerous.
The secrets of the Flairboat are the result of a longtermed R&D.
"It's a very efficient way to fly, and now you know why!" (2:06) .. the Ekranoplan way. ♥
Amazing progress, and achievement. Human flight!
The ability to control centre of lift, or amount of lift on front wing would help to better manage pitch control.
Thinking a simple hinged spoiler (pair) on front wing controlled via a bicycle brake could help? Even if pretty small, spoilers should add just that bit of extra control in addition to weight-shifting to enable endurance runs.
Hey I'm just a nobody but I wanted to tell you I absolutely love your videos. Please keep up the creative work. Watching your videos just gets my brains soaring. The possibility of your little flying machine is so cool. Thank you again. I sure hope someone helps you with their boat.
I’ve been waiting to see how long it would take for the modern world to realise the efficiency and benefits of ground effect and Ekranoplans
This is such a fascinating project, and can’t wait to see how it develops.
I understand your comment about flying something that you have created. You deserve a round of applause and the joy you have already received by completing the project!
That looks so freaking cool! Congrats on flying your own creation.
Very nice! Deserves follow up in adding some kind of elevator surface and 6-axis-gyro to improve pitch-stability.
I was also thinking to add a gyro as well and adding some shifting weight that can move back and forward. That said i have no clue on how heavy that wait needs to be and how much can be add to this concept. From what i have you seeing doing it needs to be a good quantity. That makes it quite possible that this idea of my is not able to be used is it?
This needs way more views! FANTASTIC WORK!
Thanks X3 for sharing your video ....watching you fly your creation takes me back to my younger years trying out things I built myself...back then was a bit harder because there were no stores and neither the materials nor tools neither the internet access that we have today .... it was always fun to be the actor, be with the small crow or curious people and friends that had not clue but were the greatest helpers .... it was all fun even after the cuts and bruises..... keeping the creative child in us is really an art with all the adult needs and distractions .... congratulations you have plenty of experience to make it perfect while sharing with others ; )
Been waiting, figured it was going to be successful- but so great to see you flying it!!! Amazing idea, engineering, and build. Rock on fellow human. I'll be sharing this with my middle school students.
Great project! If it’s not too much work, can you overlay/pip the current speed in your next video?
Congrats to your own designed and built machine. Awesome.
Seeing the photos is one thing, seeing the video is another. I can’t imagine what’s it’s like to ride it
That Is EPIC! I sail a foiling Moth and can still remember how cool my first flight was, I can only imagine how good yours felt!
I like it. Safety is first. Flying over water at low speed is practically harmless.
Congratulations, it's a great development. May be you can measure the tension force in the rope for power requeriments calculations. Pitch stability could be improved increasing the angle of attack in the front wing like a canard. Greetings from Ecuador
Do dual throttle handles, attaching them to split elevators (right/left) on the horizontal stabilizer.
Set them up so that the natural rotation on the throttles from forward/backward body movement cause the split elevators to counter react.
Ergo, knuckle down rotation from leaning forward would send the elevators down, forcing the nose down.
Ergo, knuckle up rotation from leaning back would send the elevators up, forcing the nose up.
The same would apply to sideways leaning, as well, which would correct for roll.
That's the solution.
FINALLY! Let's Gooooo!!!!!
Great post my friend. Super Fun indeed ! 🌞🌴⛵️
I volunteered with a ski school that specialized in teaching disabled people how to ski. In 1980 they taught me to ski when I was 10, then again when I was about 22 and went from skiing "2 track" to skiing "3 track"
In the winter they teach snow skiing, in the summer they teach water skiing. As water skiing for some disabled people means tying the ski to the boat (if they can't hold the rope). This means a quick release on the boat, and someone ready to release the rope the instant the person fell or signaled they wanted to stop. Dragging disabled people through the water is 100% politicly in correct, also, it is not very fun to experience. I know, all the volunteers had to experience being dragged through the water for a couple of seconds, just so we would be motivated to pay close attention to the skier and be ready to release the rope.
In some cases (like me) this involved dragging disabled people through the water, but it was done for a good reason, so it was okay.
That was the most satisfying and rewarding jobs I have ever had, paid or volunteer.
The system we used was way more simple that your method. There was a link between the rope and the boat. A small tug opened the link and the rope was released.
hand-operated control surface for pitch? Like a bicycle brake lever controlling an elevator? Just great content, I've been looking forward to this video since you started talking about it.
Glad to see you didn't hurt yourself. A better control system might be two poles taller than you, connected at the top and side wired to both leading and trailing edges of the wingtips. Or, if you have sufficient backing for two struts per pole, you wont have to make the control poles that high. But you will need at least two struts per side, forward and trailing to make a captured triangle. On launch you can walk through the control frame and hold on with arms behind you.
Remember that boat speed does not necessarily equal airspeed. They sell cheap digital anemometers nowadays that plug into your phone.
At least she flew. Too much more time investment into this may prove frustrating as one bad landing will result in serious structural failure. But hey, you did it and that must feel amazing. Grats!
Instead of weight shift, you could try tow point shifting. Low tow point will help getting in the air, higher tow point will prevent kiting.
Sailplanes use a high tow point for aerotow and a belly hook just forward of cg for ground winch/automobile/bungee launch. Winch tows utilize kiting for a parabolic launch curve.
Thanks
Woooowwwww sir that is over the top generous. Gratitude.
I had my doubts about the durability of the build but I was wrong completely wrong. I stand corrected with a giant smile on my face because that looks like a lot of fun. Your ambition was rewarded with what a would call a complete success. Very cool build just a fantastic result.
Congrats! Looks like you had a lot of fun! :)
Amazing Vee-hickle. Well done.
that is awesome dude. Don't quit. Please. You are making a change in the world.
Spars proove worthy! Thankyou ! Ive been studyin homebuilts for 30 years ,your proof helped show me
congrats on first flight man, that run looked killer! I love all the Ekranoplan/Ground Effect content you and Daniel have been producing; very cool stuff!
Best Squarespace sponsor ad I've seen in a while. Also, fantastic engineering and effort!
There's a reason why no ground effect prototypes use your 4 wing design.
You also need to rethink the amount of vertical stabilisation.
TAB-VII-5,TAB-VI1-5
I love the skirt idea. Similarly, What about a tube that connects the front and rear wings. After becoming airborne it would open on both ends simultaneously and the excess pressure front would be placed in the rear, and help level the structure.
THIS IS TOTALLY AWESOME!!!!!!!!
That is so cool, I would love to try and fly on it. Would love to see it have some kind of steering.
Congratulations on another great design. That looks like a ton of fun in the water. I was worried you might slip and fall back onto the vertical stabilizer. If your footing is ever an issue, you can add some gritty non-slip surface where your feet go.
So glad it worked, great project! Maybe two handles going front to back, one on each side of you like railings, rather than one right in front of you? Would let you move forward/back more.
RC towboat. Make one from an old jet ski and put controlls on your craft.
I love this project!! Maybe just changing your handle with side hand rails can fix your pitch control.
Regards 😁
Create a reverse pendulum weight pivoting at your haldlebars. As the nose rises, the pendulum swings forwards, equalising the pitch. Analogue altitude keeper.
Totally hilarious and cool. Bravo!
Hugely impressive - great results from a sleek and visually simple design. I did wonder if you could create a more progressive transition from boat to plane if you had some small hydrofoils fitted to reduce drag at the point of leaving/returning to the water's surface ?
The Perris Lake Monster lives!!!
Thank for sharing the joy
Awesome...| I think you should incorporate some control surfaces into the craft as well as add another rope release that is controlled by you the piolet. could be an Awesome new water toy that tons of people would buy.
Birds use this effect when landing.
Another thought:
Towing does create a wave street that is not there when you have some kind of propulsion on the vehicle itself...
That's amazing. Such a lot of work and perseverance. Awesome. BTW I think they used a large horizontal stab that is raised above ground effect to counter the shifting Cp, moment of rotation problem. I'm sure I've seen that in another WIG video. I'm also confident you could do it with a control system that spoils the front wing. Perhaps like a surface follower wand like they use in hydrofoil heave control.
Well done! Congratulations
Sooooo sick!!
That looks really fun.
OMG here we go! 🤩cheers from china mate. watching the vid now
dude... wow that was insane. 😱there was actually some serious airtime in these clips. i still wish there would be some automatic controlled tail surfaces on to increase flight time by gyro. if nose gets too high the tail could push it down again. same for the left and right drifting. seems body weight shift might not be enough?
also very nice to hear your happy voice while flying. aw never mind i just remember your voice in the videos already sounds super happy all the time 😜😅
An interesting and fun vee-hickle!
Very nice! consider adding elevators or canards.
The thumbnail is epic really.
You did it!!! So happy to see it all come together!!!
It seems like two vertical handlebars that you can lean in-between would be the simplest method of weight shifting.
Gorilla Glue should totally sponsor this project! The Square Reset 😂
They should!!
The boat owner sure is a good dude. I'd do it too if I were anywhere near. Or still had a boat.
Try to put a chair on small rails. When you lift, you pull yourself forward to move the CG...Also put an engine in the back with a push propeller. That's my plan for mine (different design)
Great stuff! How about gymnast parallel bars to give you more range of movement? If that doesn't work it might need a mk2 version with more natural stability.
Some ideas:
* Add some dihedral for roll stability.
* Small front cannards like another commenter said. Set them at a higher angle of incidence than the main wings to help get the nose up, but if it pitches up too much they stall and drop the nose back down. Ideally they should end up hovering just before stall.
* I'm guessing you're trying to do this without control surfaces, but at least being able to trim the tail (maybe with a bicycle friction shifter) will make things a lot easier.
Some of this could be very wrong. My aero is fairly rusty.
Very happy for you.
I used to live there and you make it sound like a totally different place to me
Well done guy! You've finally do it !
As I've said previously on ideas, you absolutely need a better vertical rudder. Including basic cablecontrol of whole surface or half if more easy to built. At least 3 or 4x actual vertical surface you have
And I think I use this mod benefit to add an horizontal control surface with big dièdre for stability and help controlling the attitude
Upper than your own size.
And for the center of Gravity, push forward your whole position.
After that it will fly forever.
Well done 👍
Cheers from France 🇲🇫
Красавчик!!! У тебя получилось!!! Я верил в тебя!!!🤙🏻✊🏻👍🏻
Double the wingspan, this will double the ground effect height, hence keep you clear of bumpy waters by a foot, I guess it helps with stability.
Give up weight shifting, you are never going to be that swift, put on some flight control surfaces, like ailerons, tail profoundor or nose canard config, maybe the front wings can tilt at will to act as canard control surfaces, stearing is easy, dive a plank in the water with a rudder of sorts at the rear end. that will help keep it going straight and take turns as water is 800 times more dense than air.
Great video! I love how it looks, flies (well.. not really), and just how it turned out! Keep up the good work! Also, here’s another idea. Giroboat. Pretty much a gyrocopter on a canoe yet again towed via boat. No power needed. That would be fun to see!
Look at bensens first gyro gliders from the '60's I have only found a few videos but it looks cool. The costs of the rotors is the painful part
Nice! Congrats on your first flights!! A dream come true indeed!
Very cool. That was fun to watch 👍🏻
I still think the canard is not set to the correct positive angle of attack relative to the aft wing. Canards are referred to as "stall proof" for a reason: There is inherent stability in the design, given an arrangement that positions the canard at a few degrees positive AoA relative to the aft wing. That should also cure your rapid center-of-pressure movement forward during weight shifting.
LAKE PARRIS CALIFORNIA! I’m surprised that they let you fly there.
I haven't finished watching the video but wanted to offer a thought before I forgot it.
It seems to me like the rope release should be under the control of the towed vehicle. That's the person that would know if he can recover or not. It could be a deadman switch which would automatically release if he falls off. Also seems like there would be less down time between aborts, with quicker reconnects. Looks fun.
Better would be to allow both to disconnect.
If you deepen the fuselage, it might allow the wings to gain lift much less aggressively. Also, you could make a handle-operated system to stall part of the front wing, enabling you to recover from high nose moments.
That was a great video, Fellow Human.
Good to see it! That was worth waiting for. Hope you get another video out of it.
Must have been super satisfying after all that hard work, awesome job!
Yes, it is amazing how far you came just with learning by doing. But be careful, ground effect forces are nothing to play with as you seem to do. A good advice of the owner of Flairboat technology.
This build needs: An Intel powered Mini PC, LED marker lights in compliance with aviation/boating laws, some custom flight software, and an elevator.
This could evolve in to whole new water sports activity.
I like your plane builds very much sir!
maybe a slight wingspan stagger so the rear wings are slightly wider than the front, but not by too much, letting them catch more air so the craft pitches up slower
Kool but I noticed the rope hitting the water kinda affected the handling
They make a ball that floats and it’s about 1/2 way on the tow line
Keeps the line out of the wake and makes a big difference when you’re tubing
Very cool, would using a "traditional" ekranoplane design reduce the necessity for weight shift?
As shown in some video excerpts, for that scale, the Lippisch design is more common. The real Ekranoplan is much, much longer, and I don't think it's any random. Now, this one is towed, I wonder if it was propelled by pusher propellers: I have the feeling there is something more than just the centre of pressure and the centre of gravity, I suspect there is a difference if you pull at a spot or push at another, intuitively you'd visualise vectors.
Now, the big question is: did you put some kind of plans online or should I redo everything starting with the CAD model and the wooden model (I loathe epoxy but I have plenty of HDPE foam and light-ish wood)?
A couple of years ago, I built a Lippisch-style model with fabric forward-swept wings (around a cylinder, makes it easy to wrap the skirt), but it turns out that 3D printing made things too fragile for my motors -- the propellers probably were oversized too and my terrace was too short, and everything broke at first start. The 5-second video shows it rather stable until it crashes into the railings, but on such distance (5 yards), not much to see or say. Now, I have a chisel...
@@RegisMichelLeclerc Ekranoplans (GEVs) with a pusher propeller have a thrust vector that is above the centre of gravity, this would create a pitch down component. Example: a burst of power could help counter a pitch up tendency. However the opposite is true too .. a sudden power reduction at speed could enhance a pitch up tendency. This assuming not other control inputs used.
When I saw the short version , I thought it was drunken frat boys goofing around . But this guy is actually legit , pretty cool.
Very good ... very inspiring!!! Keep going!
need to move your tow point higher on the boat as well as your vessel. try a wake cage
you need some side rails so you can walk back and forth 6 to 10 feet
Great work. Congrats!
Absolutely awesome project!
You NEED to get rid of the single rudder in the back, it's completely blocked by the turbulence of your body. try dual stabilizing rudders.. on the back and you could also do it on the outer wing tips.. which would give you better control as you pull the nose up. Yes.. both on the wings and the tail. The ones in the back would actually cut thru the water. cool design.. congrats
Good job, very impressive !
Great. Looks so much fun
Wing end floats will aid initial lift.
If you want to keep the same style, adjust the ability to change wings up and down, using your hand holds for aileron advantage
Wow that's so well done! Maybe rails on either side of the body would let you move your weight around easier, looks like you're still being restricted by the current handle.
