Paul,

I did a lot of background research on prop design
a few years ago and started a Excel spreadsheet
prop simulation program.  Got sidetracked and never
got back to it.  Is this spreadsheet available?

Sure Bill check out Don Bate's web site.

It is not a spreadsheet type program. It performs iterations.

"The Prop Optimizer(tm) series of three programs are designed for
separate or complimentary use. 

The Advanced program is great for the average user. 

The PRO program requires some understanding of airfoil aerodynamics. The
strength calculation is included in both the Advanced and PRO programs
and is also provided as a separate program for checking or optimizing
strength size separately for existing propellers." 


The user interface is not very friendly but it is a very sofisticated
program. If you buy one please explain it to us how it works :-).

Don will probably be at Sun N Fun giving a talk.
