Hi guys!

I'm doing a project on aerodynamical characteristics and I'm missing some data about the airfoil of the DC-8. I know that the airfoil used on the DC-8 is the DSMA-277/-280/-281, but I can't find any details. Any information about leading edge radius, chamber, etc. is appreciated!

Kindest regards,
FemaleFan

I have data for almost every major airfoil around except the DSMA 277/280/281 'series'! I can't find anything! Maybe someone else has what you're looking for...

Cheers,

That might be pretty hard to find. It looks like a proprietory wing section.

This site has one DSMA section...doubt it helps, but maybe you can contact the site owner and find out if they have more info.

Hi FemaleFan, Buzz here. I didn't know what kind of airfoil was installed, i remember hearing the story of the 4% leading edge extention.

Every so often we would install a stainless steel patch to repair leading edge . Stainless steel patches were able to be made thinner than the standard aluminum patch. That was back in the mid-80's so the details are getting kind of fuzzy.

I have a book on my bookshelf, "The Big Eight", it's some of the story on designing / building / selling the DC-8 but is kind of light on engineering.

OK it's a nice day to go flying here (near Portland Oregon) so i'll borrow my friend's Champ and fly with the windows open for awhile.
g'day
