Just a theoretical question that someone may be able to help with.
Alot of helicopters have only two rotor blades, ie:Robinsons, Bells,
etc. Others have multiples, ie:dauphins with 4, Hughes etc.
If a blade is thrown on a two blade, bend over and kiss your rear bye
bye. What would happen if you had a 4, 5, or even 6 blade?Would you
still be able to autorotate? I know the airframe would probably
vibrate violently, but would it be survivable in an autorotate, or
even low power to at least get to the ground.
Have there been instances in the past where this has happened with a
2 blade.

If you lose a blade, the imbalance will be so large as to take the
transmission and everything attached to it out of the aircraft, most
likely. It isn't survivable, just as losing a wing on an airplane isn't
survivable, except in the most unusual of circumstances.
