spinner drag spinner drag gerritgroot (Aerospace) (OP) 28 Oct 09 05:36 Hi,Does anyone know where I can find data about propeller spinner drag?Is there an ideal elliptical relation? nose radius? or whatever?(At relatively low speeds, incompressible and Re=0.3e6)Thanks in advance,Gerrit RE: spinner drag rb1957 (Aerospace) 28 Oct 09 11:12 Hoerner "Fluid Dynamic Drag" would be where i'd start RE: spinner drag gerritgroot (Aerospace) (OP) 28 Oct 09 12:43 I've got it, didn't find anything skimming through the book, I'll look again... RE: spinner drag FranAle (Aeronautics) 1 Nov 09 20:27 GerrigrootI'd try Roskam series. It contains a lot of drag estimations for shapes when you are in the design step.regards,FranAle RE: spinner drag gerritgroot (Aerospace) (OP) 2 Nov 09 06:05 Hey, thanks, I didn't think about that.I think I've got them somewhere, I'll look it up.
