Well, I'm quite ignorant in aerodynamics in general, but I couldn't find any aircraft that fits this description. And yes, I know that wouldn't be as efficient as a conventional aircraft, but I'm still curious.
From what I read in this forum about wings and aircraft that uses the Magnus Effect of Coanda Effect on spinning wings aren't as efficient than a fixed wing, and a quote I saw is very clarifying: "a golf ball uses the Magnus/Coanda Effect to fly because it doesn't have wings, an airplane, in other hand, does" (it wasn't in these exactly words, but...).
- The idea:
So, the idea is that a magnetic equipment would be inside of a sphere (I can't tell what texture or material such sphere would need) and it would spin the spherical shell so it would use the Magnus/Coanda Effect to change direction and speed. Imagine it like a spinning bullet in the air.
Of course, I can imagine it wouldn't be possible to take off with this thing, even if you somehow made it float (with a magnetic bed, I think).
- The problems:
In any case, I can think it would have a lot of problems from taking off and landing. Even so, I'm still curious about how such machine would perform.
For now, I can only think that this thing would hit the ground in a really interesting way.
