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.

Most of the weight is spar and metal eroision strip, thats the stuff you
want to keep onboard. I've been looking thru my stuff since this tread
started looking for a weight figure I read one time on what the centrifical
load was on a 206 M/R blade but can't find it. I remember it was a whole
lot more force than I ever would have guessed. Made me respect for the
strength of those TT straps.JC
