| Subject: | Re: Full trigear speed kit vs hinge fairings only |
My thoughts were to blend from near the front of the wing, around the
flap hinge and blend back out near the back edge of the flap,
which as you say would in effect fence the outer edge of the flap when
the flaps are lowered, as well as =9Chopefully=9D a
meaningful
reduction in drag on that hinge.

Can't find anything in the NACA library, except:
http://naca.central.cranfield.ac.uk/reports/1955/naca-rm-a55c30a.pdf
which applies to swept wings.
Logically, there may be an effect in reducing the spanwise flow over the
outboard section of the (fowler) flap, when the flap is deployed. But
drag in that configuration is a definite advantage in getting the a/c on
the ground. Might be worth exploring to see if there is any detectable
decrease in stall speed?

While on the subject of the outer flap hinge, given its location, my
thoughts were it might be advantageous to turn that hinge faring into a
"fence" to help reduce spanwise flow.
What say yee gentlemen to that. Or is it a lot of work for no real gain

Exactly the two things I thought would be of interest to you and why I
posted the link (pure luck that I had read this article again earlier
this
week, otherwise I would not have thought of it [Wink] )

Ok thanks Christoph

Same here, once all is installed, especially wires, the panel really fills up fast
behind. Perhaps consider thinning out the cushion behind your back by 2 inches.
Not much is needed for comfort and you gain 2 inches space and can possibly
stretch out one of your feet between both rudder pedals while in cruise Christoph
