Re: number of rotor blades

I had heard that the centrifugal load on the hub from the blade is
something like 25,000 lbs for a small helicopter.  I'm sure that there
is a formula somewhere that takes the total weight of the blade, the
RPM and the length.  I don't have it though.  I'd have to brush up on
my calculus to figure out the formula.  I'm sure that someone here
probably has it already figured out.
