Hi folks.
I'm after what impact seams and rivets (as with wood or aluminum skins) have on a 140-150 kt design cruise, all else being equal of course. Is this speed so low as to be negligible? I'm guessing not, since modern sailplane designers seem to pursue ultra-smooth lines for 60-70 knots (and finishes, but that's a different story, sorta). But does it become negligible again, say, as compared to the the drag of a windmilling (or stationary) prop? Or a soft-chined fuselage?
Thanks.
