Looking at the Lift Formula, and how we can alter its constituent parts to change the amount of lift an aerofoil is generating.

Seeing as your [actually superb] work has initiated some drag, I shall also become criticatory insofar as bad-mouthing your word usage. Air particles, while invisible and itty-bitty, can in principal be counted if you can see invisible itty-bitty things. Therefore, you can have FEWER air particles. Air itself is totally beyond accounting for, and therefore you? can have LESS air. But you can never have LESS air particles, because that would be bad. Grammar is the adhesive tape of logic.Learn it.

@LS8eighteen I’m sorry my video has offended you so. However, this video (subtly hinted at in the name) is explaining the elements of the lift formula, and not how lift is produced. For an explanation of *that*, you should check out the equally enigmatically named video 2 in the series, covering all aspects you mention. While I agree the animation with air particles could be better, their behaviour is not a focus; rather how their quantity changes with a? change in air density.

Your video is wrong on so many levels, it boggles the mind. Transition time for air particles for top and bottom of the wing are NOT equal, for example. Lift explanation with Newtons 3rd law as mentioned below is the easiest way to understand lift, combined? with the notion of circulation which you omit completely. I have commercial licenses power and glider, 2,500 hours.

@profpilotcouk Is this really? what you see on a PPL ground school?

And this is why my My indicated airspeed is very very low compared to my TAS when flying at FL330
, less? air particles

@TheC17A (Or you could see video profpilot.co.uk | #2 How Lift is Created for a more photoshopped explanation? of how lift is produced). (WIth big wigs). (And a flying Guinea Pig).

the way lift is produced is not? that particals pass over the wing it is the direction of the after flow of the air leaving the wing, generally the air is force in a downwards motion off the wing as newton’s 3rd law explains “for every action there is an equal and opposite reaction”, therefore the downwards moving air pushes the wing up thus creating lift.

L=Cl 1/2 p v2 s
L – is for lift
Cl – is for the coefficient of lift
p – (Rowe) means density
v2 – is the velocity squared
s – is the area( the area is determined by the shaddow of the wing? if light is being shined straight down upon the wing.)

amazing video
i? love this guy :’)

also if you double velocity (speed) you? get 4x more lift, half velocity 1/4 of the lift woot!

Density? is Rho (more like a P), not D.
