[@GunganWorks]

I have built a number of ground effect gliders over the years. The key is to have a very far aft CG and positive incidence on the tail. As the craft accelerates, the tail creates more lift, pushing the nose down. At the same time, as the nose lowers, the wing gets closer to the ground, ground effect becomes more powerful, and lifts the nose up, balancing the lifting force of the tail. After a few oscillations, the ekranoplan reaches a point of dynamic stability such that the faster the craft flies, the higher it floats in ground effect (but never leaves ground effect). A good ground effect craft is a terrible airplane out of ground effect-for my gliders, if you throw it fast, it nosedives; and if you throw it slowly, and it pitches up like a MIG-29 doing a cobra maneuver, and falls down like a feather. If I can upload it, I know I have video of one of these gliders somewhere...

[@air-headedaviator1805]

Ah interesting, so the designs are made to force the wing into the proper state. That makes sense

[@GunganWorks]

Air-headed Aviator that is a great way to put it. Ground effect only works in ground effect, so the tail is designed to force the craft to stay in ground effect.

[@jdrissel]

Ok, sounds like my advice on the wing stall speed vs rear stabilizer is backwards and the orientation of the rear airfoil is wrong too. I was thinking a forward CG.

[@GunganWorks]

@@jdrissel yep. Rather than pulling the nose down with a forward CG, you push the nose down with the tail.

Well, that was worth the wait, good to see you well. Great (and frustrating) project. I made an airboat from foam and a reinforced bottom. Good brushless power and fast as well. I decided that some stubby wings and winglets, plus stabilizers on the back were in order. I managed a good bit of ground effect use, but the balance of power and weight is a pain, along with cg and cf. I decided to get a brushless whoop for the lockdown, and have a Pt-17 and Zohd Talon nano on the way. This coronapocalypse is going to break me one way or another.

The saddest part of that video is that it was only 10:03 long. This and all of your videos I've seen have been so interesting that they warp the sense of time making a 10 minute video seem like three or four minutes. Seriously enjoyable.

[@darthgbc363]

4 wings with 4 motors on a really long chassis seems like the most stable setup. 1 wing & 1 motor in each corner.

[@comradesoupbeans4437]

making a small Ekranoplan is inherently difficult since the space for ground effect increases with the size of the vehicle, so the Caspian Sea Monster had several feet for a margin of error where one of the size you built has potentially as little as millimeters

[@roiwaters2807]

The simplest grond effect wing I could think of is shaped like a set square with fin at the tip on the backside. In other works - turn a set square with the long edge to the front and the angled sides downwards (this supports the ground effect and inhibits taking off and loosing stable aero dynamics) and put a fin on the back to get directional stability.

[@ninehundreddollarluxuryyac5958]

Project steamboat ekranalyork have large thrust engines up front to blow air under wing to liftoff and get to speed only. These get shut down and steamboat flies using less thrust engines in tail. Try three engines, two up front to lift wing when stationary, and small sustainer engine in tail. Shut down forward engines as soon as it flies and throttling the small engine is less tricky because entire throttle range represents bottom 20% of big engines, possibly less.

[@davidpayne4315]

[@donnyforeback4252]

James...perhaps if you put some sliders on the bottoms of the wing fences it might slide a little easier on rougher terrain

[@dylanthrust6683]

An Ekranoplanunlike a plane requires it Center of lift to be in front of the CG. That way the nose can be lift first. That is why most have engine up front to control that lift. The rear tail is needed to bring it down, So it actually work backward from a plane.

[@Taverius]

In the future you might try pointing the engines at the top of the wing like the USSR did - that's a more efficient way of getting a pressure differential :)

[@anventia]

2 questions: 1: How do you go about designing the airframe? Do you make something that looks about right and see if it works, or do you do some sort of simulation or calculations first? 2: Where is a good place to buy these electronics?

[@granttoye5852]

Actually, you would have done well to put a few motors on the back. 1 thing that the large ekranoplan taught the Russians, was that they only needed massive power directed under the wings at takeoff. Once 'hovering' in ground effect, the 2 motors at the back were the only ones needed to keep it at cruise. Pete Sripol built a model on KZbin, and Mustard has a great docu-vid on the original Russian monster that's worth a watch

[@SnowingNapalm]

While the tail thruster would create forward movement it would also push down on fuselage nosing down into water where motors forward of wings whould create the cushion of air you desire like a hovercraft but at higher speeds wouldn't be as needed as winglets finally provide thier own compressed air cushion under the plane remember the tail is not so much a lifting surface as it is a steering surface for the lifting body of acranoplane

[@sufysprojects2689]

[@2WHEELSor2WINGS]

You asked for ideas. How about a tail-sitter or tailsitter is a type of VTOL aircraft? 😎

[@TekAutomatica]

Try using reverse Delta with anhedral as invented by Alexander Lippisch

[@macrumpton]

It looks like the last version just needed a bit more power. Another thing is that WIG vehicles work much better at larger sizes because the ground effect is proportional to the wingspan.

[@allenmoore9848]

How do you calculate the CG on your craft? I had one as a push along using a reverse lippish delta style wing. The horizontal stab was angled up at the front to force the nose down. Once underway the ground effect lifts the nose, but the stab forces it back to level again. Thanks in advance Allen

[@TimInertiatic]

Can you recommend a good starter kit for getting into RC aircraft. I really like the idea of playing with some of the oddball designs...but learning with something forgiving and cheap seems a good idea. Happy building with foam board etc... Don't have any RC kit so starting from scratch. A turnkey setup that could then adapt from would be great

[@jugnoo_official9438]

hi i had a question actually i have recently build a rc plane but its tale is too much heavy and i cant add more weight because it would be cause of under power motro

[@michaeltalbot8242]

How does it turn and control pitch?

[@JosePineda-cy6om]

Seems to me an ekranoplan with canards would be more stable than your single lifting surface designs: if you pitch up too much then the canard gets out of ground effect and thus the nose immediately gets lowered until its back down at the level where ground effect can happen. Same would happen, some milliseconds latter, with the main wings - so this design would always remain in ground effect.

[@jdrissel]

I suspect both of these ekranplanes will fly with the right airfoil and morning the CG back. (And maybe a little more power on the white one). See gungan works reply - he has built some gliders. I do not think you have a thick enough airfoil in any of those models. You have very thin flat wings which are good at high speed but produce almost no lift at lower speeds. The vertical stabilizer should be a similar profile but thicker so it stalls at a slightly higher speed. This will tend to stabilize the craft when it pitches up by having the lift at the front fall of quicker than the lift at the back. This would counter the instability you can see when the red one pitches up and then stalls in your slide testing. A thicker airfoil will produce more lift at lower speeds and lower angle of attack leading to a more controllable craft. As slow as these models need to fly, make the wing look more like a modern airliner with the flaps and droops all the way down. If you determine that is too much sand some off the bottom of the leading edge. Start with about a 5° angle of attack for the wing and about 10° for the vertical stabilizer as measured when the fuselage is level and trim from there. Under steady but slightly excessive power (take off power or a little less) it should pitch up and leave ground effect briefly before setting back into ground effect. This is called fugoid oscilation. It should almost stop with a slight power reduction, but ekranplanes actually use this for stability so it will slowly pitch up and down when over a perfect surface. If instead of setting back into ground effect reliably it hits the surface then the vertical stabilizer needs to stall later and/or the wing earlier. Forcing air under the wings is actually somewhat counter-productive once you have any forward motion because the airflow over the wing will generate lift at vehicle speeds that would normally be below stall speed. In fact you can get lift without any forward motion this way, but in marine use there is suction from the water to deal with and a blast of air under the wing is just the ticket to break that grip. The pivot on the model that sank is not a bad idea at all. Arranging the pivot so that when pitched up most of the air goes under the wings but when set forward the props are over wing would be better. The reason airliners have the engines hanging below the wing has more to do with maintenance and safety than with efficiency - those mounts are designed to let the engine fall off rather than damaging wing if an engine locked up. One last tip from boat design is stepped hulls. Putting steps on the bottom of the fuselage and on the bottom and bottom sides of the end plates would probably greatly reduced takeoff thrust required without much increase in aerodynamic drag and would probably also make for smoother landings. I hope you get something flying. I have a dream of an ekranplane pontoon boat, but it would probably be crazy dangerous. Still it would be cool to blow past those speedboats and skiboats in something that looks more like a dock than a boat. LoL
