How Do Airplanes Fly?

How is human flight possible? Ever wonder how does that big hunk of metal in the sky stays there for prolonged hours and gets you to wonderful destinations?

We took a look at the interesting engineering behind how airplanes fly so you don't have to wonder anymore!

Do you know how many forces it takes to keep an airplane flying up in the skies? ✈️🤔

after watching this video my only question is, How do airplanes fly?🤔

[nevanpradhana]

Mom: son, why do you want to become pilot ?
Son : to overcome my biggest fear
Mom: heigts?
Son : D-Y-I-N-G A-L-O-N-E.

Amazing innovation! The engine architecture must be really impressive 😀

Attempting to make a mini plane using two ice cream stick and some paper without using any tutorial. This a clear explanation, thank you

[matthewalley]

Someone needs to show this video to Arthur Weasley, whose dearest ambition is to understand how airplanes stay up.

[Elnino]

NASA has specifically stated this theory is incorrect. You Need to look closer at Newton’s 3rd Law and Coanda Effect!!!

I found this by mistake now i am addicted

[sakethreddyvaka]

The video explanation of lift was great and started off by clearing up a misconception. The explanation of the airflow and the pressure created was very nice. The example of the hand sticking out of the car made it very interesting to learn.

Mind boggling engineering just did a 14hr flight on an airbus and I all I could think was thing big ass thing should not be this high up flying in the sky truly amazing

[dallascowboy]

After watching many videos on airfoils, jet engines and flight this video did make high level sense. Now if only I could find out why ships don’t sink

[collinsukpabi]

What I know is you humans who build great things for us all are special.

[luxarxtv]

I learned something new today, thank you! Great explanation .

I got one (or a couple) for you all. Please help me!

The earth spins at a 1000 mph only at the equator because there the circumference is 24000 miles(:24hr). The circumference gets less and less untill it's basically 0 at either pole. A helicopter hovering at the equator would make a 24000 mile loop in a day while it would not make any kind of movement while hovering above the pole except off course the motions of flying around the sun and simultaneously around a black hole at speeds i cannot imagine. Just ignore these last 2 motions for convenience since they are constant and we don't notice them anyway.

U could say it would have to automatically make a pirouette above the pole though because if it doesn't automatically align to the earth the world would actually spin beneath the helicopter :P And yes I understand that flying an actual helicopter requires constant manual adjustment. This thought experiment exists on a world without wind with a perfectly balanced state of the art helicopter with unlimited fuel.

Say this helicopter were to fly from the equator straight over the pole to the other side of the planet . At take off it is going 1000 mph sideways along with the planet. Then this speed would have to decrease untill 0 mph because the circumference gets smaller as it flies toward the pole. After flying over the pole the speed would increase again but.. not only that! The direction at which it goes along with the earth actually changes to the opposite after flying over the pole.


The helicopter went from a sideways 1000 mph loop toward a 0 mph pirouette and then changed "sideways" direction after crossing over the pole to then accelerate to 1000 mph again untill it's destination on the other side of the planet. Besides this it went from a 90 degree angle to 0 and back again. For the helicopter "down" is always the center of the earth and regardless of it's own speed, direction and location the earth always seems stationary. Seen from space however it has to make all these movements to stay aligned with the earth.

Objects in motion stay in motion unless acted upon by an outside force. This makes sense to me. What I don't understand is how
the speed relative to the earth gets automatically adjusted. According to Newton's law there has to be some force acting upon the helicopter so it can stay alligned with the earth. If there were no force acting on the helicopter it would keep going sideways at a 1000mph and after just a couple miles toward the pole the allignment would be broken and the helicopter would literally start moving sideways(relative to the earth) as well as forward. I know air friction is not the answer because that would be deadly. Gravity also doesn't answer my question.

So in short:
-How does the speed at which flying machines move along with the earth get automatically adjusted in relation to their position along the meridian?
-How is it possible that we don't feel the change in speed?
-How can a helicopter hover above the pole without seeing the earth beneath it spin? What makes it allign with the earth so the earth seems motionless?

If you've made it this far I thank you for reading. I would love some respectfull answers to these questions burning on my mind. I have believed the earth is spherical all my life but I can't wrap my head around this! In fact I never even thought about it until I heard a believer of the flat earth mention it.

To those who don't understand what I'm asking here I say :

If someone decides to smack u with the end of a broomstick. Would you rather he made the same movement with a stick of 10 cm(0.33 feet) or 100 cm(3.33 feet)?

The earth is a sphere. It spins around its axis. From the axis to the outside of the sphere is the "radius". The radius is longest in the middle of the sphere. From the middle to the top and bottom(poles) the radius gets smaller and smaller. If u measure the sphere in the middle u get the length of the equator. If u measure it at any point at a 90 degree angle to the axis u get the circumference. The radius and circumference are directly related to each other. Because the earth revolves around it's axis once every 24 hours the time is set however the radius and circumference are variables. The longer the circumference the more distance is travelled in these 24 hours and so we get the 1000 mph at the equator of 24000 miles. The closer you get to the poles the smaller the circumference which means that the speed at which u move along with the earth gets lower and lower untill u are at 0mph at the pole.

He forgot to mention Bernoulis theorem. Take off & descent are based on it. The wings of an aircraft are designed accordingly

[matthewajlouny]

great video. The engine is not the only reason that the plane flies. Newtons laws explain a lot about lift other then just pressure diffrerence. fluid will have to act in the opposite and equal magnitude

[justinmiller]

This was a great explanation of lift! Your explanation of lift that states that air flowing over the top of the wing needs to meet the air at the bottom of the wing was good, but not very thorough. Additionally, you implied causation between velocity and pressure, which is incorrect, as these two factors effect one another simultaneously. However, I enjoyed the fact that you mentioned the impact of shape on lift, though I feel as though you failed to give good reasoning as to why this is. The faact that you mentioned putting your hand out of a window and making different shapes was a very good comparison though and brought me back to my childhood. Thanks for the great video and keep it up!

I was gonna say sticking your arm out the window but he beat me to it
