:Or maybe not: It's the plane of the wing of the plane! [[Special:Contributions/172.68.51.160|172.68.51.160]] 07:21, 29 September 2022 (UTC) | :Or maybe not: It's the plane of the wing of the plane! [[Special:Contributions/172.68.51.160|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 [[User:Elektrizikekswerk|Elektrizikekswerk]] ([[User talk:Elektrizikekswerk|talk]]) 09:23, 29 September 2022 (UTC) | : Yeah, I also don't think that this is a mistake.

If you want to know how a wing really produces lift, it's complicated, and the best reference on the net for that is [http://www.av8n.com/how/ See How It Flies].

:There's also a [https://www.scientificamerican.com/article/no-one-can-explain-why-planes-stay-in-the-air/ Scientific American] article from a couple of years ago that says there's no scientific concensus.

:It's quite simple really - without wings, people wouldn't believe the plane would fly - the wings create faith, and faith lifts the plane.[[Special:Contributions/162.158.159.125|162.158.159.125]] 15:15, 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.[[Special:Contributions/162.158.159.125|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.

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

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.

: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. [[Special:Contributions/172.71.102.49|172.71.102.49]] 07:26, 30 September 2022 (UTC) | :I can see why this was confusing.
