Give us empirical data to show that RDS gives % reduction in drag, and this x-% reduction in drag correlates to a y-% increase in "performance"-- speed, sink rate, whatever.
I have "nothing against" the RDS system, and it seems to be a wonderful idea, but these discussions take on the flavor of religious dogma with little empirical data to demonstrate claims. Let me see a before-and-after set of numbers to evaluate. --Bill >From: "Harley Michaelis" <[EMAIL PROTECTED]> >To: "Bob Pope" <[EMAIL PROTECTED]>, "Bill Harris" ><[EMAIL PROTECTED]> >CC: <[EMAIL PROTECTED]> >Subject: [RCSE] RDS drag reduction, speed increase. >Date: Fri, 16 Nov 2001 16:52:20 -0800 > >Just thinking, if 5% reduced drag could increase speed that much, a 16 >second run would be reduced to 15.2 seconds.
