hennie we cannot possibly do that what would the neighbours say being serious interesting topic -skin friction at the molecular level makes methnk about the tesla turbine
we could go to a mat finnish suppose but how about those who flew with just the primer on their planes -did they see any difference phil ----- Original Message ----- From: "Hennie van Rooyen [HQP]" <hennie.vanroo...@kumbaresources.com> To: "KRnet" <kr...@mylist.net> Sent: Thursday, April 13, 2006 10:26 AM Subject: RE: KR> Armoural > > Hi all, > > Just my 2 cents on this subject.

Therefore a very slight rough surface on i.e. a wing (pinholes) will produce less friction than a very smooth wing surface and therefore also higher top speed. > > You actually want dull surfaces for more speed as bright smooth surfaces are purely for appeal and not for speed.
