Hi folks,
Attached is a spreadsheet for calculation of propeller tip speed both static
and moving through the air. Thanks to Bernie and Bill for the equations - I
have not attempt to verify the equations, but they appear to be accurate and
further more if you put zero airspeed in the moving prop equation, you get
the same calculated values as the static prop - so appears they are in
agreement and accurate.
You may change any value shown in color Blue - the rest of the spreadsheet
is protected so folks don't accidentally erase an equation in a cell by
putting a number in it. But, you can view the equations in each cell, so if
someone wants to duplicate it unprotected - have at it.
Enjoy
Ed
