Talk:2678: Wing Lift

Any chance this is related to the equal-transit-time fallacy? 162.158.146.57 16:19, 29 September 2022 (UTC)

For more information have a look at my paper here-https://arxiv.org/abs/2110.00690 AerospaceDoctor (talk) 02:59, 30 September 2022 (UTC)

"The plane of the wing" - looks like Randall messed up on the title text InfoManiac (talk) 05:52, 29 September 2022 (UTC)

Or maybe not: It's the plane of the wing of the plane! 172.68.51.160 07:21, 29 September 2022 (UTC)

Yeah, I also don't think that this is a mistake. The word "plane" is not used as the device that can fly but as the description for the (bottom) surface of the wing. One word for two totally unrelated things. I removed the trivia-part. https://en.wikipedia.org/wiki/Plane_(geometry) vs https://en.wikipedia.org/wiki/Airplane Elektrizikekswerk (talk) 09:23, 29 September 2022 (UTC)

If you want to know how a wing really produces lift, it's complicated, and the best reference on the net for that is See How It Flies. B jonas (talk) 09:39, 29 September 2022 (UTC)

There's also a Scientific American article from a couple of years ago that says there's no scientific concensus. Barmar (talk) 13:13, 29 September 2022 (UTC)

It's quite simple really - without wings, people wouldn't believe the plane would fly - the wings create faith, and faith lifts the plane.162.158.159.125 15:15, 29 September 2022 (UTC)

It's even simpler than that.  As the air goes over the curved top of the wing, it has farther to travel; this creates a pressure differential between that mass of air and the air beneath the wing.  This low pressure draws the wing up, like pulling liquid up a straw.  So in other words, airplanes fly because the wings suck.

Lift is not complicate if you look at Prandtl’s original work, and Doug Mclean has done a good job editing the actual Wikipedia article. If you consider the entire atmosphere the asymmetric flow around an asymmetric body in a fluid results in an asymmetric pressure distribution, which is equal and opposite the pressure on the ground. That is, a wing produces a pressure difference that is transmitted in steady state to the earths surface which ultimately supports the aircraft as a reaction force. The asymmetry in the flow is the result of fluid mechanics and can be determined from Navier Stokes, which is Newtons laws of motion applied to a fluid, with viscosity. People get lost because they want to invoke momentum transfer, which is not needed in the global view. To see where the momentum transfer is occurring, you can only utilise think slices of the atmosphere as the control volume, hence the reason it is confusing. This is compounded by people seeing trailing vortices and stating that those must be the mechanism for the momentum transfer, and they are not. This was all established over 100 years ago. That Scientific American article is click bate, and I immediately asked the editor if I could write a response to it, and I got no reply. AerospaceDoctor (talk) 02:39, 30 September 2022 (UTC)

Could the spooky skulls be an inderect reference to quantum spooky action? Not sure how that would apply to lift, though.

I assumed this was in reference to recurrent discussions of the use of 'golf ball' dimpling in anything related to aerodynamics. AFAIK this is entirely theoretical/experimental as far as use in aircraft wings, but I imagine it's something that crops up a lot in semi-informed lay conversations on the subject. 172.70.86.26 15:31, 29 September 2022 (UTC)

This, following "Aviate, Navigate, Communicate", suggests to me that Randall is in the middle of a private pilot training course and reflecting on its lessons. BTDT. 172.70.38.237 14:32, 29 September 2022 (UTC)

it says 3 main reasons and then lists 2?? 172.69.68.20 15:13, 29 September 2022 (UTC)Bumpf

If you mean 1) Bernoulli, 2) the angle, and 3) Coanda... that's definitely three. If you don't, then I'm not so sure what you're referring to. 172.71.178.187 21:15, 29 September 2022 (UTC)

Can anyone help fix my reference. It said citation needed, so I went to the first great source, which is Prandtl. However, even though I followed the wikipedia way for making a reference, it has not produced a helpful link at the bottom. AerospaceDoctor (talk) 02:46, 30 September 2022 (UTC)

I can see why this was confusing. On this site, there's an inside joke surrounding the citation needed tag, based on an older comic and on the way it's used in the What If section of xkcd. It basically means the opposite of what it means on wikipedia, and is sometimes inserted as a joke behind obvious statements or common knowledge. Your edit was fine, don't worry. No actual citation needed. 172.71.102.49 07:26, 30 September 2022 (UTC)
