Very long boring technical discussion of Lift Faries adn ThrustDemons....(NASA)

An ostrich after all, with all it's feathers, CAN'T FLY. Oh, come now. You need to apply mathematical and scientific reasoning. It's already been experimentally established that it takes two pounds of feathers to lift ten pounds of Canada goose. An ostrich weighs much more than ten pounds, but does not have a commensurate amount of feathers. Feathers are not magical, they operate by strict scientific principles and an insufficient amount of feathers won't even make a fruit fly. If you want to convince me that it's not feathers, do some experiments. Attach a pound of feathers for every five pounds of ostrich, and toss the ostriches out of an airplane. Do this a statistically significant number of times, and then we'll talk turkey. Jose OhMyGod! Shades of WKRP in Cincinnati! |

The Impossibility of Flying Heavy Aircraft Without Training
I just got my new Chevy Blazer, and returned to the dealer the next day, complaining that I couldn't figure out how the radio worked. The salesman explained that the radio was voice activated. "Watch this!" he said, "Nelson! The radio replied, "Ricky or Willie?" "Willie!"...and On The Road Again came from the speakers. I drove away happy, and for the next few days, every time I'd say, Beethoven!" I'd get beautiful classical music, and if I said, "Beatles!" I'd get one of their awesome songs. One day, a couple ran a red light and nearly creamed my new car, but I swerved in time to avoid them. "Chicken**** Assholes!" I yelled. The French National Anthem began to play, sung by Jane Fonda and Michael Moore, backed up by John Kerry on guitar, Al Gore on drums and Bill Clinton on sax.... Man!, I LOVE this car! Richard |

lift, wings, and Bernuolli
There is a *net* downward momentum of air.
I have several aerodynamics books that say differently. Otherwise there is no lift. If there is a pressure difference between the top and bottom, you will have lift. Your airfoil is blisssfully unaware of the air with which it has no contact. No. wingtip vortices are caused by downwash. Infinite wings don't have wingtip vortices because they don't have ends, not because they don't have downwash. Again, I have many aerodynamics books that say differently. Even Aerodynamics for Naval Aviators. On Fri, 24 Feb 2006 01:22:36 -0600, "Highflyer" wrote: Disagree. There is a *net* downward momentum of air. Otherwise there is no lift. However the downward momentum for any finite section of the infinite wing is infinitesimal. Note, however, that even though in Calculus 100 we assume that an infinitesimal is approximately equal to zero and can be ignored, it is only approximately to zero and only very very near zero. While zero times any number is still zero, almost zero times infinity is NOT zero. Ergo, the downwash is not zero either. |

Obviously it IS impossible. After all, they did it with three of them

Very long boring technical discussion of Lift Faries adn Thrust Demons....(NASA)
So, after the test flight, how do you get down from your
mechanical goose? Surely everybody knows you don't get down off a goose, you get down off a duck (eider for preference). Eddie Bauer uses goose down. Jack Bauer never ever sleeps and saves the world every 24 hours. Aunt Bea learned how to fly and soloed on Andy Griffith [a really good episode], but she usually cooked birds. I heard that fast airplanes go so fast because the aluminum is afraid of noise, the more noise the harder the aluminum tries to get away. Penguins have feathers and can't fly because the air is too thin, but they can fly in water. Humans don't have feathers and can't even fly in water. I did see a video of a guy who jumped out of a helicopter wearing a batsuit and flew down a mountain http://www.alexisparkinn.com/photoga...06-batsuit.wmv and it looked very cold. Maybe cold makes people fly? How do you get down from a horse? Some people fall off.

Shades of WKRP
I have lurked here for years, waiting for some words of wisdom I could cling to, at last a discussion I understand .....sigh..... |

In article . net, Richard Lamb says... According to Shafer "Lift is caused by Lift Demons. These little, invisible demons hold on to the leading and trailing edges of the aircraft and lift it into the air by flapping their wings (so, in a reductionist sense, lift is actually caused by feathers). First honest thing I've read in this thread. Lift is caused by feathers is a known scientific fact and I can prove it . Take a 10 # Canada goose and it will fly very nicely. Now pluck all the feathers and then watch this now naked Goose do high speed taxi's with it's little naked wings flapping wildly. The Goose sans feathers cannot fly so the answer is obvious to those who take the time the think about it. The average goose has 2 pounds of feathers so therefore for every pound of feathers you can lift 5# of goose. Therefore I propose that we build a man carrying mechanical Goose to prove this phenomena. We can start small with say an Ultralight version with a gross weight of 600#. We would need only about 120 # of feathers. We will need to fund this all important project so I'll be accepting donations...cash only . Later well do a project on how speed is caused ,you'll be amazed how it works.A small clue is electromagnetic plasma pulses rectified by an alum pyramid shaped hat. Don't forget to send money ... Lift Faries?? Pure bunk!! It's feathers my boy feathers!! Count Clipper Well, Chuck, I have to admit, you almost had me won over. At near 10 stone, I'd need to collect only 40 pounds of (pretty!) feathers and I'd be able to fly just like Peter Pan. Finally, a life long dream realized! Researching through my technical library, I came across an ancient documentary film - "Those Magnificent Men And Their Flying Machines". In the opening sequence, Red Skelton attempted feathered flight. Fortunately, for the squeamish souls among us, this tragedy was filmed in a very long shot. But that shot DOES allow us to measure the L/D directly from the filmed evidence. The result was a dismal .01:1 glide ratio... Well, back to the drawing board... Richard |

("ChuckSlusarczyk" somehow found the keyboard)
I can for see a time when men with a huge fire coming out from behind their butts could go as far as the moon in vertical flight. "Behind their butts" is similar to "talking behind someone's back" ...which is essentially IN FRONT OF THEM - if you get right down to it. Therefore "a huge fire coming out from behind their butts" is really ...OMG! Um, this has already proven not to work ...25 years ago at college - and only when I pee'd. Montblack Not the hook!
