This piqued my curiosity so I called up an engineer I used to work with. Here's the skinny: While you're probably not going to really hurt anything using this stuff, it takes serious knowledge of boundary layer theory and a lot of calculations to use it right. (You just might get lucky and put it in the right place, who knows.) It works best with smooth, high contour airfoils in high lift situations. On top of that, it needs to be placed at a specific location to really work right. That location varies by airfoil, altitude, airspeed, and a host of other things including the amount of bugs splattered on the leading edge. I can't parrot the techno garble, but it has something to do with a laminar flow separation being far worse than a turbulent boundary layer that sticks. Long story short, it's neat stuff that won't do us much good. The wings on an Ercoupe are already "rough" and cause a turbulent boundary layer of their own accord, especially the cloth covered ones. The net result is no real benefit for us. I didn't ask him about propellers, I assume the same applies. -Chris > -----Original Message----- > From: Ed Burkhead [mailto:[EMAIL PROTECTED] > Sent: Thursday, February 12, 2004 10:38 AM > To: Coupe-Tech > Subject: [COUPERS-TECH] Dimple tape > > ----[Please read http://ercoupers.com/disclaimer.htm before following any > advice in this forum.]---- > > > > This looks interesting.
