Message #659 of 1371 |

I have an airfoil profile Tom Speer designed for LYDIA, with a 0012
flap (approximately). I'd appreciate Tom's thoughts on that foil now
some 17 years later.

One last thought: Flying on a 757 last week, I noticed the aft-most
fowler flaps had vortex generators tucked in the slot. Has anyone
ever tufted the flaps to see if they are causing flow separation at high
angles?

John, I just want to make sure I understand right. I would have thought that you would start with a big flap deflection and then ease off as you go faster. ...	foiledagain20	Dec 10, 2008 3:03 am
