Anyone else, besides me... going to the Oshkosh, WI airshow?



I can't wait!

I was going to make the trip from Alaska but I couldn't get all the money things ironed out. Seems the insurance company wanted way to much money to fly down.



RT66DOC, pick up this months Private Pilot. They have a couple page feature on Aluminum Overcast. And a couple articles on OSH.



I'm going next year. I'll either fly myself or buy a plane ticket. I'm going. Maybe buy a one way ticket south and buy a plane down there?!?!?!

No, but my company is sending me to NBAA in Oct. for a day. Oo.

Thanks for the tip C-Pilot.

Soooooooooo, since we were talking about vintage aircraft and WWII fighters, who here can tell me why the Spitfire's wing is considered "elliptical", and why it is basically the only elliptical wing to ever make it into production?



And on the new water-cooled V8's for GA... . finally! Why in the world is it that I can drive my Cummins for 10,000 miles w/o using a single ounce of oil and you can't fly a 300HP C206T for 1 hour w/o burning a whole quart! Dam engineers finally did something! Wait, I'm one of them... ... so, what do you pilots want to see in future planes?

Re: the Spitfire, I believe it was the rounded shape of the wings and that they were wider near the tips... . here is a good site that shows the wing (btw: I believe some of the german WWII planes were elipitical as well)... http://www.clarkindustries.on.ca/spitsxii.html

Negative... . next guess? Here's a clue: It doesn't have to do with the shape! (well, it does, but not in the matter of it's geometrical properties)

Maybe it has to do with the weight of the wings? heavy at both ends but light in the middle??? just a guess... . curious as to the answer???

"Heavy at both ends but light in the middle?" That would be Ohio.

The wing wasn't shaped like a reg airfoil (flat bottom)... ???

I have no idea we give already

sorry guys, forgot all about this post since I wasn't subscribed to it...



It has to do with the downwash on the wing created by the unequal pressure (top to bottom). On a standard wing there is a large amount of downwash at the tip, and it gets less and less the closer you get to the root of the wing. On an elliptical wing, the downwash is constant over the entire wing, making it handle much differently (better?). THe problem is that these wings are expensive to design, and even more so to build.

Cool! Great question!
