- Hi! In this video we look at an Airfoil or Aerofoil, which is the cross sectional shape of the wing. The Airfoil is mainly responsible for the lift created on the wing. We look at different terms and their definitions related to an Airfoil. We also look at the different types of airfoils.
Apologies for the Robotic Voice! :/

Keep the videos coming man
We love it!!
Thanks man! Will do!
Thank you for sharing this knowledge 🙏
My pleasure :)
Your videos are excellent, Thank you so much 🙂
You're very welcome!
You made aerodynamics so simple!!!!
God bless you;;;
Keep going;;;
Thank you! Check out my other videos as well!
why is the airflow above of the wing faster than the airflow below the wing?
The shape of the airfoil causes the air flow to accelerate.
Very useful
Thank you! Check out my other videos as well!
謝謝
Welcome!
Hi, do you know any other institution besides NACA that designed Airfoils?
Excellent video 👌
Thank you! I am not sure, would have to check!
I think the aircraft manufacturer designed their own airfoil shape so its not naca
only for this answer someone?
if it is a symmetrical wing? 🤔 0:47
The pressure over the top and bottom surface will be equal so no lift is created.
If an increase in angle of attack increases lift, isn’t lift because of angle of attack?
No, there is also lift happening at 0 degrees angle of attack.
If you choose a higher AOA, you are of course increasing lift, but at the same time drag is increasing also. So there's an optimal point where lift/drag ratio is best, usually lower than 5 degrees AOA
Is a 'positive camber'when the camber line is above the chord line. And 'Negative camber' when the camber line is below the chord line?
Thanks!
Thank you! Check out my other videos as well!
sir are you a pilot or ame
I am an Aero Engineer and Instructor!
The authors have two wrong scientific approaches: researching the creation of Lift force and Low pressure at upper side of the wing, relative to the ground surface and Earth. I explain the aerodynamic cavitation and existence of Lee side aerocavern, and creation of Aerodynamic force.
Thank you! We communicated on email as well!
@@JxJAVIATION When a solid body in fluid is displaced, in its previous place in a moment, in a small time lag that cannot be measured, there is/was a "cavern in the fluid".
The body moving through the atmosphere pushes and swept out the air along the way and creates an aerocaverne - a zone with subatmospheric pressure on it backside.
Lift is not upforce! In the dictionary, Lift means pick up and move to a different position. In aerodynamics, Lifting is a lateral moving, Lift is component of the aerodynamic force that "displaces" an object from the line of air flow.
the lift force is actually due to Newton 3rd law and not because of Bernoulli's theorem..
Its a combination of multiple concepts!
I didnt understood the camber line shit
