Thanks to rb1957 and mohr for the links. I havent looked at
Hoerner yet but the latter NACA link looks promising as it relates to radials which is what i have in mind. many thanks

I'm calculating the change to Cdo as a result of increasing the engine sizes on a twin piston engined aircraft. The change to basic equivalent flat plate area is simple enough using the increase in nacelle area and the appropriate factor. However there is another consideration, ie increased...
My guess is that you and i are talking about different things. The 10 kts you probably have in mind is a safety margin over minimum drag speed designed to prevent one inadvertently slowing to end up on the back side of the power curve in turbulence or when turning. What i am talking about purely...
Hi Guys,
I'm doing some historical research on aeronautical engineering and hope someone can answer a few questions.
Best range speed is always a little higher than Best glide speed for a prop aircraft due to the fact one has to take engine efficiency into account OK, as I understand it Vbr...
