Let's change the subject.Simple: how does a Frisbee works? The simple explanation I find by typing the innocent phrase "How does a Frisbee works" says that the air on top moves faster than the air below the contraption. Don't bother to go to Wikipedia, the knowledge of how a disc rotates faster on top than below is still under cover.
Let me raise my humble objections to this (for the novice) ridiculous explanation, knowing in advance they will be crushed by the unsurmountable power of this humble and wise forum (may the gods of electronics keep Tomba away from harm!):
I fail to see why this rotation theory could work. Simple: the air on top and the air below rotate at the same speed relative to the disk. I'm tempted to add the word "duh", like in "duh! the disc is solid, for the love of Pete! How are you saying to me that it rotates faster on the top? Are you out of your mind, dear physicist?".
The explanation also talk about angle of attack. As the Frisbee profile is symmetrical, I also find this explanation unconvincing. There is no wing profile at work. If you take a flat plate, the size of a Frisbee, and throw it in the same "angle of attack", to test this theory, you'll convince yourself that this kind of non-aerodynamical drag cannot make a Frisbee to "float" the way it does.
A chopper, more complicated as it can be, is very "understandable" for a person like me: you have a wing and the wing rotates, period. In the end, I have not the same level of respect for Mr. Igor Sykorsky as the one I'm quickly developing for the Wham-O Toy Company, be his corporate soul blessed.
Could this be connected somehow to Area 51? The Frisbee was invented in 1947, Rosswell happened in 1947, then the rotating disk aeronautical craze began. Coincidence? I don't think so.
Some people will say: "UFOs, Ciro? Oh, c'mon, have you lost it? What about clay shooting targets? Surely they precede Wham-O and Rosswell... And what about the Frisbie pie platters?". Yeah, keep dreaming: as if they didn't meddle with history and with your own minds!
So, rotating air or alien invention?
What's the story on the aerodynamics of Frisbees? If you can understand how a sidepod works, the regulations about safety cars and the financial history of Bernard Ecclestone, surely you can solve this enigma.
For example, I also find that " The outer third of the Frisbie disc is called the 'Morrison Slope', listed in the patent".
So, oh, please, illustrious aerodynamicists extraordinaire, lighthouses of knowledge, vast abysses of understanding, will you englighten this little grasshopper? Is there any alien in this forum, besides me, that can give us a simple explanation (you, know, for Earthlings, wink, wink).
