Fluid mechanics (Bernoulli's theorem) and Newton's third law do not provide a complete explanation for lift.

Something else is missing: torsion physics.

And no one understood torsion physics better than Viktor Schauberger, the inventor of the jet engine.

You need to understand you are wrong.

Planes use wings to fly and glide. They can still glide without power. See the link.

Are you also saying propeller planes do fly with wings?

Yes, we know about captain Piche's formidable skills as a pilot, using the Airbus330 as a glider. However, in order to glide you need to reach a certain speed, easy enough for a single pilot glider. Fill a Boeing 787 with 300 people, on the ground, and try and glide that aircraft. It won't work.

This is what Newcomb was describing: the laws of physics, as we know them, do not permit a much heavier than air airplane to take off and fly with hundreds of people aboard.

You need torsion physics, the Schauberger effect.

If all you've got is Bernoulli's theorem/Newton's third law, certainly you'll need magic to explain lift on RE.

No can explain how airplanes fly, not even the best engineers at Boeing. Not even one.

Newcomb provided the calculations: it can't be done.

You need torsion physics, the Schauberger effect also to explain lift.

So why is the force in the upwards direction? How do planes fly upside down?

And gliders that dont even have engines still use this effect?


That glider is using the engine in the airplane towing it.  I live near a glider field and have seen tow planes pull gliders to altitude many times.  There is nothing magical about it.

No need for airplane's wings to be shaped like usual airplane's wings.

Flat wings are also okay. Even that was the case for earliest airplanes ~ at the beginning of 20st century.

Why the buck did Bernoulli's Principle showed up afterwards??
Because Bernoulli's Principle deals with fluid dynamics in general, not airplane wings exclusively.

If another lift force comes from air flow (bounch) between the plane & the ground, the plane's gonna take off a little bit. But the plane will fall again when the altitude gets a bit higher. (No air bounch anymore).

The case is, the lift from below works all the time regardless the altitude.

That's how DUD works.

First the quotes are opinions from over 100 years ago. They have no relevance today.

Second the paper reads like it is from a philosopher. Clearly people understand lift. Planes like the F-117 and B-2 aren’t just accidents.

Thirdly no one of those quotes or sources agrees with you. Do you even have a source that will clearly say a plane’s lift isn’t from the wings?

Cut the crap.

Lord Kelvin and Simon Newcomb, two of the best mathematical physicists, applied the known laws of mechanics/fluid mechanics to the subject matter and found out that an object much heavier than air cannot sustain flight. If ideas from one hundred years ago have no relevance, according to you, then a paper written some 350 years ago, should have no relevance either, right?

This is a proven fact.

Then, you need an additional force to keep the jet airplane in flight, which is derived from torsion physics.

The article proves that no one today, not even the best engineers at Boeing, has any clue as to how lift is produced.

No one has the slightest clue as to how the F-117 (as an example) has lift.

The article proves it.

If you think you know better, please outline the physics: Bernoulli's theorem and Newton's third law are dismissed very quickly when it comes to explaining lift.

All of those papers agree with me: lift cannot be explained by using the known laws of mechanics/fluid mechanics.

I don't think you understand what their conclusions were. It was a matter of practicability. They did not think technology of that era was capable of realising it, not that lift is impossible. Other people disagreed. Turns out they were wrong, and the other people were right. It happens.

Another quote by Newcomb:

Quote
Quite likely the 20th century is destined to see the natural forces which will enable us to fly from continent to continent with a speed far exceeding that of a bird. But when we inquire whether aerial flight is possible in the present state of our knowledge; whether, with such materials as we possess, a combination of steel, cloth and wire can be made which, moved by the power of electricity or steam, shall form a successful flying machine, the outlook may be altogether different."

So clearly his objection was that technology of that era couldn't realize flight, which was wrong because he failed to anticipate airfoils, even the rudimentary ones used back then (no, they weren't just using completely flat wings, contrary to what op says), as well as advances in internal combustion engines.

By Ed Regis

One of the best scientific journals, using the most significant sources comes to a very certain final conclusion: no one can explain lift.

If you read the article (which is published in a popular science magazine, NOT a scientific journal, and as such aims to be somewhat clickbaity), you'd realize that what the author is actually saying is that none of the usual simple, qualitative and intuitive accounts offer a complete picture as to why lift occurs, since the naive Bernoulli explanation has all sorts of problems, and the 2nd law explanation doesn't fully account for the phenomenon either. But the author DOES say that modeling fluid flow using the Navier-Stokes equations does account for the phenomenon:
Quote
Contemporary scientific approaches to aircraft design are the province of computational fluid dynamics (CFD) simulations and the so-called Navier-Stokes equations, which take full account of the actual viscosity of real air. The solutions of those equations and the output of the CFD simulations yield pressure-distribution predictions, airflow patterns and quantitative results that are the basis for today’s highly advanced aircraft designs. Still, they do not by themselves give a physical, qualitative explanation of lift.

So the Navier-Stokes equations which model fluid flow do account for lift, the only issue is that qualitatively explaining such a complex phenomenon is hard, because just showing to someone the Navier-Stokes equations doesn't make them understand what is physically going on very well. But that doesn't mean that the hydrodynamics of air don't completely explain lift, they do.

But it doesn't.

"Still, they do not by themselves give a physical, qualitative explanation of lift."

Please upgrade your knowledge of the Navier-Stokes equations.

Here are the ether Navier-Stokes equations:

Physical vacuum is a special superfluid medium

St. Petersburg B. P. Konstantinov Nuclear Physics Institute,
NRC Kurchatov Institute

University of California, Berkeley


We have a 500 ton behemoth with hundreds of people aboard, which is able to gain lift and fly into the atmosphere.

What causes the lift? It can't be Bernoulli's theorem, Newton's third law, high school bull sessions using low pressure on top of the wings, or the Navier-Stokes equations.

Something is missing: torsion physics.

No airplane could lift itself off the ground on a spherical Earth.

Airplanes can fly only above the flat surface of the Earth using torsion dynamics caused by ether drift flows.

You age getting confused here. It's possible to use new discoveries to improve existing things. It's not a difficult concept.

It's not difficult to ..... debunk Bernoulli's principle.
No real dicovery is based on something that doesn't exist.

If it's so easy then just create an experiment, record it and publish it and become famous.

Make a youtube video showing how you disprove Bernoulli's Principle.

Otherwise, it's your word against a large amount of evidence and experiments.  And we all know how much THAT is worth.

Like, it's not hard to verify Bernoulli's principle on your own...

Comparing the modern plane's wings, with plane's wings at earliest aeronautics history is certainly easy for everyone.

Thanks to internet era that makes anyone as if had a huge library. Before internet era, nearly all students probably didn't know about flat wings on planes at earliest era of aeronautics.

But I already told you that old plane wings don't contradict Bernoulli's principle... It's simply that the usual explanation of how lift works is not very adequate. Again, it's not that older plane wings contradicted Bernoulli. The way these wings worked was that when the wings were slightly tilted upwards, an area of lower pressure was created right above the top of the wing, while the bottom of the wing pushed slightly downwards on the air incident on them. This is similar to the way modern airplanes work (their wings are always installed at an angle to create the effect I described), and the airfoil shape is such that it both maximizes that effect as well as minimizing drag and stress on the wings. Bernoulli's principle does have something to do with all this, but the way it comes into play is more complex. The bottom line is, air does flow faster at the top of the wing, but it isn't just because of the shape of the airfoil, but more because of the slight tilt of the wing.

So the way it works is not according to the naive Bernoulli's principle explanation which only mentions the shape of the airfoil that is sometimes offered, and you are right that the lift is not created by the shape of the wing, and that the same can happen with different shapes of wings. I mean, fighter jets can often fly upside down, which according to the naive explanation wouldn't be possible. But the fact that Bernoulli's principle shouldn't be applied in that naive way to explain the phenomenon without further elaboration doesn't mean that it is wrong. Bernoulli's principle simply states that when you have an increase in the speed of the flow of a fluid, you have a decrease in the static pressure of that fluid. There is the simple Bernoulli equation that we learn at school which only applies to incompressible fluids like liquids, and there is also a more general one that also applies to gasses in some cases, but its action isn't as simple as that.

If Bernoulli's principle is reviewed independently, or not necessarilly put into the explanation about 'lift', it's fine.
My main concern is definite: Bernoulli principle is not a must to build a fuctional air vehicle.

About the tilted wings, if that is the case, isn't this system gonna urge the pilot to 'dip' the plane all the time due to natural adding of altitude and 'hiking' path? Moreover if the speed is high. To me tilted wings system is not necessary.

Passengers need convenience with the plane going horizontal, not tilt up.
Even the plane's design has a similar issue, i.e. the cockpit part will always be lighter than the rest parts of the plane, not to mention those parts have more burden with passegers and luggage.

Again, my focus so far is not the Bernoulli's principle itself, except in its connection with aeronautic designing.

A plane acts like a skimming stone over water.
Anything flying horizontally, must angle wings against that, whether the whole wing is slightly angled or the leading edge of a straight wing curves over and down to an angle  to the rear of the wing.

A plane is just an air speed boat. You're just skimming along.

It takes a closed system with uniform atm to realize a lift. It will fullfil the mechanism of action - reaction at propellers for thrust.
The thrust itself, or moving condition is the requirement for air hit from underneath of the plane. The more speed the more volume/mass of air hit upwards.

If another lift force comes from air flow (bounch) between the plane & the ground, the plane's gonna take off a little bit. But the plane will fall again when the altitude gets a bit higher. (No air bounch anymore).

The case is, the lift from below works all the time regardless the altitude.

That's how DUD works.
Actually, it's called ground effect and is fairly well known.

Ground effect ain't exist anymore when the plane's altitude is getting a bit higher. It will land back. That's what would be the case if gravity existed.

If it's so easy then just create an experiment, record it and publish it and become famous.

Make a youtube video showing how you disprove Bernoulli's Principle.

Otherwise, it's your word against a large amount of evidence and experiments.  And we all know how much THAT is worth.

I have uploaded some of such videos on Youtube. Unfortunately it's in Bahasa Indonesia.

Famous? Is it a pleasure thing? I have no idea. But many famous people said it's like living in a jail.

Majority is mostly wrong.
