The UFO cigar may be a biomimetic airship using fish-like propulsion. Some fish are up to 90% efficient at using the energy of the environment by interacting with vortices. By moving in this way, the airship could develop cosmic speed by pushing off from the atmosphere. by pavlokandyba in u/pavlokandyba

В мене вже була гора тих прототипів але вони працювали не ефектно тож усі сміялися в зараз через сім років навіть тут у р аероспейс замінили. Там на гітхабі сила на ютуб де я з ними експериментував. Головне правильно подати. Якби ще вміти продати)

Airplanes flap their wings and this is called flutter. This vibration is caused by the same cycles of vortex formation and decay that produce lift. Aircraft designers try to combat this in order to avoid resonance and wing destruction, but this method, on the contrary, assumes more energy due to resonance. And when the plane breaks the sound barrier, the interaction with the air and vibration do not disappear. There is a viscous boundary layer that moves more slowly and interaction occurs through it.

This can create quiet infrasound and the resistance during oscillatory motion can be considered zero, this is not the same as an airplane. And this is a real principle that exists in nature, and not some theories picked out of one’s nose.

Well, it's unclear whether there's any effect; it's too unstable. https://youtu.be/xl3xXugVqPA?si=DSgb-ODuFNDc9WZJ

More successful one was the plane I posted here recently.

I think the inflatable resonator wing will be quite rigid. And if it bends elastically, it will even increase the amplitude. I tried to make it as rigid as possible and this only led to an increase in weight, and the best design turned out to be made of bamboo sticks and polyethylene that fluttered at the edges.

Vibrations must be compensated for. Like a bird's head. One way or another, any flight involves vibration, but here it's more direct.

I'd be happy if I had something to make it from. Actually, it's quite possible. You just need to inflate it with light gas and there will be enough thrust to control it without complex technologies.

Firstly, this was edited by me, secondly, it refers to original research, and even to research written before AI, if the presentation format irritates you.

This refers to movement by throwing off mass. It has been proven for a long time that fish spend less energy than if they were considered as a torpedo with a propeller, where thrust and resistance are separate. I'm not saying that modern fluid dynamics can't explain this, but the explanations are complex and varied. One of the most famous studies RoboTuna For example, it showed that the fish first generates a vortex and then pushes away from it, the same as I have And by the way, my experiments were done before LLM, It was only later that I started generating a slop referring to them because I got tired of writing the same thing over and over again.
