That said, I sure hope my prop sim program has produced as good a blade

in

the real world as it is on the computer screen!  ;-)   It's only zeros

and

ones until
it is really tested.

You were the Man I was going to ask for help from
until Vance was mentioned.

So about this Prop sim program, can you help me out there.
I know it's not proven, but I could play with something like this.

To save a bit of time here is Bill's spread sheet.

George,

Send me your e-mail (  bfreeman@kcnet.com )  and I'll give you
the latest version of the spreadsheet - hope you have XL and know a
bit about running a spreadsheet.  We can discuss this directly if you
want to play with the spreadsheet, I'll give you some pointers.  It isn't really
an "easy to use" tool for just everyone, but takes a whole hell of a lot of
stuff into account and is based on Von Mises theoretical workup, so
I suspect it will be at least pretty darned close.  If you are doing
a fixed pitch prop, you should read the comment on fixed pitch back to
Ken Powell in a just previous post.
