How do airplanes stay in the air? - Raymond Adkins

video description

Rating: 4.5; Vote: 2
Explore the physics of flight, and discover how aerodynamic lift generates the force needed for planes to fly. By 1917, Albert Einstein had explained the relationship between space and time. But, that year, he designed a flawed airplane wing. His attempt was based on an incomplete theory of how flight works. Indeed, insufficient and inaccurate explanations still circulate today. So, where did Einstein go wrong? And how exactly do planes fly? Raymond Adkins explains the concept of aerodynamic lift. Richard: I used to teach basic Physics to students in HS years ago. Debunked the idea of Bernoulli's law to explain flight and the notion that lift is generated by the difference in the flow of air above and below the wings. Physics books continue to teach this.

As an aerospace engineering graduate, this pretty much sums up what you learn in basic aerodynamics. And because of we still don t know how it happened, we used a lot of coefficients (which is derived from experimental methods) to account for them

Use to stick my arm out of the car window while dad was driving on the highway
Sometimes my hand/arm would just slap the door or. if I felt it right. would ride the wind. Just had to move my hand and arm to match the wind perfectly ig

You only explained the first of the 3 terms in the equation and made it seem like that's basically it with some details. The other two terms are ALSO very important and crucially are often left out of popular explanations.
reply

That's your theory. My theory is that it runs on belief. Everyone just believes the plane will fly, so it does. Once they stop believing it'll fall back down. It's just like Wi-fi, there's no way that's real.
reply

It doesn't matter how a plan flies. What does matter is that the first inventor was Brazilian inventor Santos Dummond
Wright Brothers invented a human slingshot
Dummond invented the airplane.

Literally just now looking out the window watching a propeller powered plane take off from the local private airport wondering exactly the question that makes the title of this video.

now lets go over what causes turbulence, cause i be ready to sht myself had an extremely shaky flight one time through a storm and have had flight anxiety since

Another interesting fact about the Navier-Stokes equation is it's one of the millennium prize problems in math. You will be awarded 1 million if you solve it.

I work across the airport and whenever I can I take a minute off of my computer and I look at the airplains getting airborn. Now I know how they do it.
reply

its explained how to take off
but how the plane stay float in air?
is it because the movement of propeller in the engine? i dont quite understand it

reply

Things fly bc they have a momentum. If I throw a ball it flies, if I put wings on it it can go up & down, if I put a propeller it can keep itself in the air.

reply

It's just turbolence, physics of fluids in motion
No, a wing detatched, look!
Hey, I'am the pilot here, just let physics do its things!
