How Does A Plane Wing Work?

What was the last flight you went on? Where did you go?

You missed the horizontal stabilizers in the drawing. Without that, a plane is uncontrollable.

Does anyone else legit just watch these videos but are too lazy to actually try and make it lol PRETTY COOL HUH

Dave, Thanks for explaining that Bernoulli's principle is a mis-applied and incorrect explanation for wing lift. The Coanda effect , or "Wall Attachment effect", is responsible for the laminar air flow on the top surface to follow the contour of the wing (if the angle if attack is not great enough to stall the wing).Proof experiment: gently hold a soup spoon with its convex surface slowly nearer and nearer to a running faucet's stream of running water. As soon as the water stream just touches the backside of the stream, the Coanda effect will attach the stream to the spoon and instantly pull the spoon (lift!) closer to the stream. The fluid pulls the air out from the boundary of the spoon and the water creating a low pressure area which allows atmospheric air pressure to push the spoon and water together. You will have created "horizontal" lift. Key point, the resultant water flow is now flowing in a new direction. THAT is the downward reflection of air coming off the trailing egde of the plane. If you put pressure gauges on the ground under the flight path of a plane just taking off, a higher pressure will be momentarily sensed. Now hear this: the total mass of downward moving air coming off the trailing edge of a flat or airfoil shaped wing is equal in that instant, to the TOTAL WEIGHT OF THE AIRCRAFT. Fly a giant imaginary scale under the plane as it is flying and it will measure most if the weight of the plane as it is flying....the giant air cushion is there. Wing tip vortices are simply the faster downward moving air and the realtively level air near the tips if the wing attempting to re-join...causing dangerous for too-close- following aircraft, rotary clear air horizontal rotary turbulence. Who said "Every force has an opposite but equal reaction." ? Right. Put an entire jumbo jet on a giant scale or table and the plane will transfer its weight through the table to the ground. How else could anything be supported? The push of the wings of a flying plane essentially push down on the air. The faster the air flow the "harder" or more solid the air becomes. Thus , faster plane, smaller wings. The final question NOBODY is asking is "why are wings fatter in the middle? Elementary dear Watson! Answer: That is where the support spar was when marerial science had provided only limited strength materials. Look at the airfoil of an X-15. Practically flat. And to make it very clear...planes actually can fly upside down. I learned this when I was 10 years old from flying .049 powered U-controlled (control line) model airplanes that I designed and Not from incorrect science books. I am a pilot.

PRETTY COOL HUH THIS DIALOGUE NEVER GO OLD

I really enjoyed this video since it is a bit more science centered and it also has a pretty simple way for explanation that even kids will understand i would like to see more videos like this

Dude, now I think he's a professor.😂

Never did I understand how planes really flew until your experiment. Thank you.

Very well explained and demonstrated Sir 👍 Thank you.

I knew most things about airplanes Some of this I learned from you Thanks Dave

The lift force of the wing profile is created due to the difference (difference, Delta) in atmospheric pressure. Another thing is why two such zones are being created? The most working hypothesis is that the mass of air elements - molecules - have inertia. And this inertia of the air flowing around the front upper part of the wing creates a vacuum zone behind it, and the oncoming lower part of the wing is a very small seal. Compaction is a weak force in this pair, and vacuum is a much larger share in the lift of the wing. This is what explains the behavior of your model in the film.

Wow, that's so awesome! Thanks for sharing about it! 😉

My son was studying aeronautical engineering in ICL - he did try and explain a few things, but it flew over my head (haha)!

(GASP!) The explanation was perfect. I hope you’ll make more educational videos like this one.

Amazing ! Learned from this.

Honestly I learn more from this than school

u can put vertical tail below too to stabilize for wing from below too

hi im jenil from india i would like to thank you that you made this video for us and i request you to make more videos on this in heavily detailed also some aerodynamics in simple language thx GREETINGS FROM INDIA

Please folks, this is a simple experiment to understand how physics and an airplane can work. It's kind of silly to ask about horizontal stabilizer and other things that are obviously not relevant since the purpose of this video is to provide a basic explanation. Stop asking nonsense.

You can see that the straw is tilting rightward, so maybe you could reduce friction between the straw and the string if the string was also slightly tilted rightward. great video as always :)
