Benouilli Effect: How Airplanes and Paper Fly

[Chagur]

Yes, Fairfield, you did:

The importance of the "lift" airfoil design is over hyped
because most airplanes can be flown upside down
without losing altitude, it just takes more gas.

Completely ignoring that when flying 'upside down' you
are relying completely on an increased angle of attack
and that the required AofA increases drag; hence the
greater power/fuel requirement.

No, zoobyshoe, I cannot read minds, but I do know a little
about aerodynamics. A simple vector force analysis is all is
all that is required to determine even extremely slow flight
or 'flight' via turbulence creation, the 'flapping of wings',
either by birds or insects.

Given the required control surfaces and sufficient power,
even a kitchen table can be made to 'fly'. An excellent
example would be 'the hopeless diamond' which became
the F-117 in its combat configuration.

OK Chagur, I over simplified the problem. I completely agree with you.

That's good, cause neither can anyone else here. Therefore quote the remark you are taking exception to, especially when you are being irritated and testy about it, because otherwise it looks like you are referring to the last thing said.

I am not sure why you are directing this explanation at me. I am the one who said earlier that it is possible to design a wing that works exclusively on Newton III.

Thanks for the suggestions, Fairfield. The dashes were not moving, and nothing I did would make them start. WebTv can download nothing. It's just a modem and a keyboard. Not even a mouse - you have to use the arrows. (I can plug a printer in, which I have done, because these just print straight off the web.)

Now that webtv has been exposed, may I suggest an economical computer with a Windows operating system, and all the needed extras, which can be had for about $440 (before tax and shipping) at

" http://www.tigerdirect.com/applications/Category/category_tlc.asp?CatId=6 "

If you love the frustration of installing the operating system yourself you can get a computer for about $300, and buy a slightly passe version of Windows at

http://www.recycledsoftware.com/

for about $100. The software sold there is not used, just superseded. Make sure you get an OEM version of Windows, and not earlier than Windows 95, if you buy it. You'll still need to get a monitor, or else an adapter card to use your TV as a monitor.

Not a bad suggestion at all, except my finances are such that the odd 4 or 5 hundred dollars that comes my way must always go to maintaining my vehicle, among other more pressing things.

The webtv is as limited as you can get and still be on the web, and I find I have to make excuses for it frequently, but it is cheap and, at this point, that overides the limitations.
