Scott Campbell's Article on Airfoils and Turning Ability

[hohun]

Hi everyone,

Seeing Scott Campbell's name mentioned in the news section of the Indysquadron website, I wonder if he's active on this forum, and interested in a discussion of his great article on WW1 aerodynamics.

("Airfoils & The Turning Ability of WW1 Fighters", published in WW1Aero #182 and, according to WW1AERO, originally in AERODROME #140.)

Basically, I've probably used a very similar approach to the one he chose, though my focus mainly was on WW2 aircraft.

I've recently been trying to see what results my approach might yield for WW1 aircraft, so it would really be interesting for me to compare notes with Scott, especially as all the complicated bits are not covered by the article.

Here's an attachment showing what kind of results I get from approach. Scott's article covers a much greater variety of aircraft types, which would get confusing in my presentation. It does cover the drop-off of performance with altitude, though.

Different from Scott's approach, I didn't account for the different wing profiles of the various types. I'm also off a bit in assuming the use of a constant speed propeller, simply because I'm not sure how to handle fixed-pitch propellers mathematically.

This is in no way the final word on the three types, depicted, but rather a demonstration of the type of results my approach delivers. Just as Scott pointed out in his article, everything has to be open to criticism and question in various ways :-)

Any comments or questions you might have on this, or any tips on how to contact Scott in case he's not actually reading this forum, would be highly appreciated. Many thanks in advance! :-)

Regards,

Henning (HoHun)

Scott is active in the game, but he no longer lives in Indy or plays with us regularly. He moved to KS and started a new squadron there. Pretty much anything that makes dogfights fall rather than climb would be welcomed by DP'ers!
