Greetings.

I have been working on a spreadsheet that would compute the Reynolds number that a propeller works at.

One of the variables here was elevation.

Locations
Urbana 738
Racine 620
Kent 1050
Lakehurst 101
Kibbie Dome 2610

Before I submit this, if there are any locations you'd like me to include, please send it my way.

Also if anyone knows of a way to compute dynamic viscosity in air given elevation and temp in the same equation, please send it my way. It would make the spreadsheet even easier to use...

Also I am including data points for two outlines - John Kagan's 'Fatboy' outline and Brett Sanborn's 'Source Decay' outline.
If you have others that you'd like me to include, please send them my way in a simple format.

Prop shaft to beginning of blade length. i.e. 1 inch

Length from innermost part of blade, width (both in inches) Fatboy below...
1.25 1.6875
2.375 2.25
3.5 2.48
4.625 2.48
5.75 2.25
6.875 1.6875
7.25 1.3125

Also please do not let the F1D data fool you - this will work with all prop types. I'd love to include a couple pennyplane or A6 props.

Regards.
