How Airplanes Fly
NTIS AVA08357VNB1
What makes an airplane get off the ground and stay in the air? Easy to understand film combines animation and live sequences to explain ... all » basic aerodynamics. Forces of lift, weight, thrust and drag are shown in relation to flight.
Physics never goes out of date. I would imagine that airplane in the video is still in operation today
@hunkrahul11111: Correct! that's why it is impossible to get a car moving from start with gear 3, 4 or 5 because they're soft gears, meant for cruising only
aerodynamics is the only reason im pickign aeronautics engineering next year.. !! amazing .. love to be in the world of aviation
4 years of aerodynamic engineering science in 20 mins. love it
I am a big fan of aviation and i have knowledge about how an aircraft flies. But ive never seen the info this good.
Old but very very clear explanation!!!!
Good stuff!
Hello from future 👋
thanks for video
Again, thank you science. SCIENCE RULES!!
how old is this video? the dust thingys, the voice, the fashion? great video though :)
Thanks a lot for this video....helped to clear some quesions on how it takes off.
thanks for that nice video
it heps me to clear lot of things about flying
nice video
well explained.....
Wow, I was expecting this to be full of misinformation and the like which always work their way into these ye olde informational videos. I'm rarely happy of being wrong, but in this case I'll make an exception, favorited!
I couldn't tell you for sure but my understanding is that for most major airlines, if your glasses or contacts correct your vision so you have 20/20 acuity, then yes you should be fine.
?
A simple proof that it is primarily AOA (turning flow) that is critical - is that a flat plate, a kite, a hang glider all produce lots of lift with low drag. So many people think a wing has to be curved on top and flat on the bottom but this is simply not true. make yourself a paper plane and prove it. Flat plates work just fine but stall at a lower angle of attack. Wings are not venturis, the upper airflow does not speed up to meet at the trailing edge ever, in fact the upper flow slows down.
No worries- not circulation flow theory.
As NASA describes it,"lift is a force created by turning a fluid."
Turning flow is what happens when solid objects come into contact with a fluid and the object changes the direction of the fluid. The flow turns. The resultant force is known as lift for our purposes. A flat plate or symmetrical aerofoil at 0 AOA creates no lift. Incline it to the relative airflow and it does. Turning the air causes lift. Pressure diff is a result of this, not the cause.
I own an airplane so I know what makes airplanes flys. Its money, no doubt about it.
is it because the elevators move in sync why it doesnt affect the roll of the plane?
yeah i was thinking all thats missing is little timmy "but how do the wings hold the plane up Mr gelson?" "im so glad you asked timmy!" lol
In high school I chose Aviation to satisfy my Science requirements. We watched this film in class.
the best video ever!!!
Interesting and excelent video.
Great video!Keep them coming!
is there one about turbulence..I'm a nervous flyer and i figured one way to calm myself down is to understand what happens when an airplane flies...
This helped me on my test thanks
excellent^^^^^^^i just cleared my misconceptions
I wonder if it is possible to make a circular airplane?
why did i suddenly remembered old cartoons watching this video?
OMG IT'S SUNDAY NIGHT HOW LONG WAS I OUT!!!!!!
fab! nice and clear!
Great video.
The aerodynamics of lift is wrong here. How old is the source of this video?
Very great!
Pressure differential is primarily caused by AOA. Flat plate wings prove that. Lift is caused by turning flow. I have yet to see a satisfactory explanation of circulation flow and why it is not visible in a wind tunnel or in CFD.
Well said.
1968, and I know what you mean, they didn't talk anything about the axis of the aircraft or their static and dynamic stability.
very nice old video
Money can buy planes but it takes the qualifed pilot with fundamental understanding of aerodynamics to fly planes safely. I would have been the last person to fly on a plane piloted by some one who think money can make airplane fly. Money can ofcause make planes more close to nature resembling eagles for instance.
I Love it!!
Not true anymore regarding the glasses comment. As long as your vision is correctable to 20/20 by your glasses, you're fine flying or training to fly with most airlines.
It depends on the country you live in.
looks easy - now give me fighter jet and some rockets
i thaugh it was cool 20 mins. of flight school in your house or were ever you are
go on...
Bernoulli's Principle is an entirely incorrect assumption for what causes lift. It dramatically underestimates the component of lift on the suction surface of the aerofoil. It's an old video but unfortunately it teaches the misconception which needs to die.
To be fair, Physicists/Aerodynamicists tend to work at the fringes of performance where they are trying to explain things that may make a very small difference. To an airline this is big news as 1/2 a per cent can make a big difference but the overarching principle of how aircraft fly has been known since the very early days of aviation. It is simple turning flow, otherwise hang-gliders, kites and paper planes wouldn't fly. People also misunderstand Kutta. and misquote this all the time.
Good
The only problem is that wings are not venturis and never will be. A venturi behaves such as it does because it is a closed system. A wing has no relation to a venturi. This video is very misleading. Wings work by bending the airflow.(Turning flow) It is turning the flow that causes the pressure differential not the wing shape as shown by the symmetrical aerofoil and also by supercritical wings that are used on all airliners which are curved on the bottom and flatter on top.
The plane in the video wasn't cleared for landing so thats why it took off when it touched the ground. (LoL just kidding it was a touch and go) :D
1968
I read this comment and I was like "That's like totally something I'd say". huh
Anyone els had this weird thought all the time in the head (barrel roll) while watching this video? :/
I also have an Airplane, I put money in fuel tank but it doesn't fly,
how
dated but somewhat reassuring
When the narrator speaks of the equation, he tries to sound like an professor. Not a good narrator should be like this
yeah it's funny how people get carried away with silly notions. I teach this at university to pilots in a degree program and it's amazing how most have been taught equal transit time or the wing is a venturi stuff. When I throw a paper plane at them and ask them how it works, they get very quiet. I have had intense discussions with 10,000 hour airline pilots who still believe equal transit time... I tell them, stick your hand out of a moving car window and you will figure it out...
really? i thought it was the engine
Money make plane fly.XD
haha, there is no such thing as free huh.
Let's bone up on basic aerodynamics!
This is so so dated!!
