Our help centre (and more specifically our on-topic page) states (emphasis mine):
Aviation Stack Exchange is a site for pilots, engineers, controllers, mechanics, and aviation enthusiasts. If you have a question about…
Flying technique, maneuvers, navigation, procedures, etc.
- Air Traffic Control
- Aviation Weather
- Aviation Regulations
- Aerodynamics (related to aircraft)
- Aviation Safety
- Aircraft Design and Manufacture
It is safe to say there are a lot of very smart people here, who understand the fine details of avionics, wing design, aero-mechanical engineering, the physics of flight etc.
Very occasionally we will get a question which is quite obviously not "related to aircraft" but is almost certainly answerable by the sort of experts who frequent Aviation StackExchange.
Status quo dictates that those questions should be closed. They are not on-topic, but with lack of a specific site (Wings.SE? Sailing.SE? Aerodynamics.SE?) we're perhaps the best place on the network to get an answer. There is some argument that Physics.SE would be the most appropriate however this particular example would not be a good fit.
In principle questions about aerodynamics/hydrodynamics (or whatever else might be "wing-related") are on-topic [on Physics.SE], but your particular example would be off-topic as engineering and/or homework-like, since it asks about a specific solution to a problem rather than about the physics behind it. chat
So we're left with a choice of 3 and I would like the community's opinion which would be best
- Close as off-topic (Status quo)
- Update on-topic advice to include wing design but not related to aviation
- Attempt to migrate questions about non-aircraft wings to Physics as long as they fit that site's on-topic reason
Or perhaps there is a fourth, better, option that I have not thought of?
Note that this has been discussed back in 2014 but it is sometimes a good idea to get an updated opinion from today's community.
