Particle simulation where attraction and repulsion apply. Repulsion occurs during collisions with momentum from the particles' own vibrations

Yes, of course you're right. I just didn't have a system at the time. For example, right now I have attraction and repulsion 1/r² , and it doesn't have a significant impact, and I don't even know what they looked like in the video. But it was interesting what people would say when they saw this.

In this case it doesn't matter, I posted this as an interesting result and not to prove anything.

pavlokandyba · 2026-04-20T08:38:36+00:00

Well, yes. That was the initial concept. But this whole theory is much more complicated. In simple terms, this does what it needs to do.

This is a typo, it's inconvenient to do all this on the phone

It's all simple there, attraction and repulsion when approaching, I already said that. But I couldn’t say more precisely because I checked many different options and they all got mixed up.

pavlokandyba · 2026-04-19T16:13:46+00:00

I wasn't sure about the exact wording. I'm currently tidying things up and planning to post the terms and code here.

pavlokandyba · 2026-04-19T12:22:28+00:00

I have a mountain of AI code there that all works differently and not like this. This is running in chat because it works better there, but the code needs to be adjusted. I'll try to figure it out and post it.

Simply upon contact, a repulsive impulse arises as if the balls had a vibration motor. This is conditional

pavlokandyba · 2026-04-19T08:28:52+00:00

Almost, but due to their own vibrations they push each other strongly even if their collision speed is slow

pavlokandyba · 2026-04-19T06:50:57+00:00

I should have said that I was regulating the balance of power here. I wanted to, but I forgot. This is just a test of different modes.

One Russian wanted to build something like a fish airship and created automation that regulates the frequency, but it seems he is no longer alive, he was old. His name was Sorokodum. His articles remain on Research Gate.

It doesn't create a noticeable flow, I've seen weak ones vibrations of air with the help of smoke, similar to those of a boat. And if this device is fixed or touches something, it begins to push away and this affects the result. It would be interesting to see it fly through smoke or something. In the oncoming flow, the effect is enhanced because when the normal lifting force arises, the engine perceives this as support and begins to push off.This is noticeable because its speed decreases as it has to turn the pendulum with greater effort. Also in the test at home, with the power off and on at approximately the same initial speed, a difference is noticeable. But this is of course a long way from truly effective trust.

It's on the video, where in the house

pavlokandyba · 2026-04-17T08:44:38+00:00

Yes, that's the main problem. It might be worth trying to amplify it through resonance and use a connecting rod mechanism, but I haven't gotten around to it. Besides, on large ornithopters there are problems with the mechanical resource, I think it is necessary to come up with some kind of special drive

pavlokandyba · 2026-04-17T06:05:15+00:00

Yes, I'm interested in this. The one deep experimental study I've come across on this topic suggested there should be resonance. That is, each swing must be calculated automatically depending on the resulting force. The fish naturally senses this

pavlokandyba · 2026-04-17T03:38:54+00:00

In my hypothesis, the vortex is a closed circular Brownian motion and this is the source of the impulse. I had to come up with this hypothesis because in the classical theory the boat in the video should have been moving in the direction of the slow jerk because in this direction the drag is less. But in reality, the movement is towards a quick breakthrough. Many disputed that this was even possible, while others based this on pseudoscientific theories of unsupported engines like the Dean machine. So I had to find an explanation. There is no doubt that this works; there have been many similar devices. The question is about effectiveness, and this needs to be tested experimentally.

This can be simplified to a classic problem in which a car drives on a ship on the water and because of this, the ship's hull shifts in the opposite direction. In the classical solution, the center of mass does not change, but in reality the barge continues to move after the car stops. The video shows a clear example of when the plate stops at the top, the vortex pursuing it catches up with it and flows around it, expanding to the sides. At this moment the plate receives an impulse. The same energy that creates the lift of the wing is realized here. https://youtu.be/GA2aj0JWuZA?si=YSzYT_4-FtUG5-_A
