As a training manager on Sikorsky helicopters I monitored a class being presented by a US Army instructor teaching H-37 flight controls and dynamic systems. One of his students asked what would happen if the H-37 lost a blade in flight. The instructor replied that the remaining blades would reposition themselves and the helicopter could continue flying.
The centrifugal force (and if NickLappos is reading this) the centripetal force created by the spinning blade is around 72,000 pounds which would create a tad bit of imbalance.
