Department of Transportation Federal Aviation Administration How Airplanes Fly 1968 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.

That’s interesting, the other Jimmy must have quit YT & left his screen name for someone else (you). Sorry for bothering you. Take care.

I’m no engineer, but I think you’re right on the money. I don’t think airplanes are sucked into the sky. Look at how much downwash a helicopter makes. It couldn’t fly w/ neutral blade pitch.
I don’t think they explain stall right either. The condition called “stall” is the loss of laminar flow w/ a significant increase in drag. That doesn’t mean it stops producing lift tho. It’s just the drag increases way beyond the thrust of most airplanes’ engines ability to keep it up.

@jemhson no, that is not wrong. What the wind tunnel is showing is that air gets compressed when you have two airfoil shapes and that, even if you take one away, the same kind of effect happens. It is done to make more sense of how lift works because it shows how an airfoil acts like a funnel almost. Concerning biplanes, their wings are not like that. The airfoils are “upright” so to speak

hello the corect ans to ? is, air plane fly bq have wings

This is so retro! Thanks.

you can experience stall by playing gta san andreas using the same plane shown here by pressing w+down arrow quickly from the keyboard during takeoff. Its a 0 airspeed 0 altitude scenario.

hey at 03:48 seems wrong, why is the wing on top upright? is that what really biplane airfoil is? note that it cancels lift from below by the top airfoil

I would say, make your move by imbalancing forces, then you have to make them in-balance)

This theory is outdated, the major causee of lift is the reaction of the bottom of the wing surface forcing air downward. The low pressure on the top helps a bit, but the most lift is because of the theory “every action has an equal and opposite reaction”

This video was very helpful, Im taking ground school right now and I had a hard time understanding what angle of attack was
THANKS

Thanks for uploading! Very interesting and educational. Has really helped increase my understanding lift and the other aerodynamics.

This video was the first video i ever watched at my local aeroclub where i started my Pilot License!

Thanks for uploading! certainly a really education one though it is in 20th century!
Btw, the video says. All forces must be imbalance ? or does it means, in- balance? can someone enlighten me please?
