Geeze! I had a scientific physics oriented totally gurued explanation of why an airfoil lifts when inverted but it went into cyber space when I had to leave my computer to save a lady who was drowning in a river somewhere. Anyway, airfoils don't care if it is straight up or crooked down. The secret is the angle of attack and the reaction to the flow off the trailing edge. The airfoil will react to the decrease in pressure on the more curved surface and it will react to the flow coming off that surface. " Inverted" flight is the same to the airfoil as setting the wing at negative angle of attack in level flight. It will still produce a pressure differential but in a very inneficient way. The best thing is to have a symetrical airfoil that will only produce a pressure differential when there is an angle of attack, " up" or down. I just made all this up and you already knew it anyway.

Hmmm.....interesting story. Did she give you a sword? ............... Oh wait... that was the "Lady in the LAKE " Ok so they don't care. From what you are saying, an aircraft travelling vertical develops lift from the airfoil.... Isn't that lift 90 degrees, to the direction of travel? Lessee... level flight... lift = up^ (away from the force of gravity) Vertical flight... lift = some direction other than up. < > (perpendicular to gravity??) Do rockets have lift, when flying parallel to the surface?? How big do you have to make a plane, to NOT be physically & areodynamically able to fly?? Is the moon really made of green cheese? and If so, why hasn't the Cheese and Macaroni companies capitalized on this?? Who ever heard of orange cheese anyhow? Will the price of fuel ever get back, to what we grew up with? If a hen and a half can lay an egg and a half an hour, how much is a chicken dinner?? If a chicken Catches Tori, wouldn't "Mr Spelling" be upset? SEE! It wasn't me that started something... It was all you guy's with the right answers! Thank goodness I don't have the answers, cause there'd just be more questions! :0
Like the rocket flying straight and level, you're a boot in the ass. Here's a real stumper for you. It's very sientifiker. If a centipede a pint, how much would a precipise?
OOPS ! I'm a flyer, a writer, and a painter. Not a speller. But. I'm havin a good time in my ol' age.
It's amazing what a few scotches will do to your spelling. Of course, I NEVER do that so I wooden know. It's pretty neat, though. I can go flyin' whenever I want and I don't have to buy the gas. I jes sit and think back to 1945 and the years after and have more fun than you can imagine. Av gas was something like 35 cents a gallon. Rent a Stearman for 12 dollars wet and go out and have a ball. The cumulus clouds in the morning were cotton puffs to play tag in but in the afternoon they had turned into big bad boys that stretched to 30,000 feet and dumped vertical rivers of rain and blasts of lightning that convinced you to stay on the ground and watch. I just made that up and you guys know about that stuff anyway. Switches
Lessee.... If a centepede a pint than a waterfall would likely result from a precipice. At least it makes sense to me.
Did all this actually start with a question about slips? Ain't it funny how things can segooey from one thing into sompin else? It's like jumping off a PRECIPICE to find out where the edge is. And that has nothing to do with segooeys or slips.
'cept is you forward slip off a precipice, at the bottom one would se(e)gooey! (I can' believe I've gotten caught up in this.)
I don't remember what started this......I wuz two cornfusecated... Just remember this....you can always segooey on a slip , but you can't always slip on a segooey.... specially the ones spelt differntly, unless there's a banana peel, nearby.... Er...phonetically that's 'seg- oo- ey' as in: segment, ooh-la-la, and hey you! But we ain't usin the phone... This hear is the Interject! We love youse too, Roy! Hmmm... "If a centipede a pint, how much would a precipise?" That my dear friends, depends on the size of his bladder and prostate.... ( an old "man's" joke) Charlie
You would "se(e)gooey", only if you were Elmer Fudd! Everyone else, would "see gray" I can sell you a can of "Propwash"....cheap! It cleans up every liddle im"prop"er mess.... Uh huh!! You're caught up in it..... alright...! Charlie
And to think, there are people like this who are out there flyng airplanes around by themselves ! ! The situation prbably improved when I had to quit. Switches
Sounds like Homeland Security has done it's best....... But I still don't feel any safer.... Too many udder piluts out there.. I hate Flying Udders!! dripping .........Er... TRipping out... me! I am.... Come to think of it.... I never felt in any danger from terrorists... even on a trip to Europe, back in March/April '03 Ummm..... Oh yeah, Except for those with "DDS" after their names.... Why am I yawing to the left??
