Prop pitch calculation

Greetings.

I've been working on a fixture for cutting prop blocks.

Here is the Excel function required:

=ATAN((2*PI()*U7)/S14)*180/PI()

U7 here equals c in Fujikawa and Zseleczky's paper (See page 6.) I think it would be called moment arm typically, this is the distance from the center of the pivot to the angle the pivot arm rests upon.

S14 here equals pitch.

I'll upload a quick and dirty Excel spreadsheet a bit later.

Regards.
