EC665 Tiger PT3R HAC - s/n 98+23 - Berlin SXF, Germany - 17 May 2006
The Tiger's main rotor is a four-blade FEL-type hingeless design with fiber elastomeric bearings.
The hub is made of a titanium centerpiece with composite star plates bolted on top and below.
Flap and lead/lag motions are allowed by elastic bending of the blade necks, pitch motion is allowed by elastomeric bearings.
Lead/lag damping by solid-state visco-elastic dampers (visible at upper left).
