I came across this: http://www.nasa.gov/press/2013/november/nasa-boeing-finish-tests-of-757-vertical-tail-with-advanced-technology/#.UoV8GJGyxBU
Even though I find it hard to imagine this having any impact on GA design the development is very interesting nevertheless.
Not another one please – I’ll not be made a fool twice, at least not from the same name, and not at so short in interval!

I beg you pardon?
Who is going to tell him this time?

Beautiful. If this were Facebook, I’d want to hand out a double-like now.
Jan, I think there’s nothing wrong with this press release. 
I can’t see what it actually does. Can anybody explain it?
I am not sure, but it looks like they re-energize the flow over the airfoil. There is a transition point where the airflow gets turbulent and further a separation point were the airflow gets separated from the airfoil. With this technology the airflow “attaches” longer on the airflow, reducing the area needed to produce a force to get things done (lift ect.).

This involves adding energy into the airflow, but evidently the net efficiency gain is large enough for them to consider this to be applied to the design of future aircraft.
