Abstract:
1. A helicopter rotor damper system for damping a motion of a helicopter blade relative to a helicopter rotor, said helicopter rotor damper system including: a torsional damper with a damper centering bearing providing a damper center of rotation axis, at least a first elastomeric torsional damper, said first elastomeric torsional damper having a first elastomeric torsional damper torsional elastomer bonded between a first elastomeric torsional damper first torsional damper nonelastomeric bonding surface and a first elastomeric torsional damper second torsional damper nonelastomeric bonding surface, at least a second elastomeric torsional damper, said second elastomeric torsional damper having a second elastomeric torsional damper torsional elastomer bonded between a second elastomeric torsional damper first torsional damper nonelastomeric bonding surface and a second elastomeric torsional damper second torsional damper nonelastomeric bonding surface, and a damper link interface, said damper link linked with said elastomeric torsional damper, wherein said elastomeric torsional damper and said damper link are connected between said helicopter blade and said helicopter rotor with said first elastomeric torsional damper first torsional damper nonelastomeric bonding surface rotating relative to said first elastomeric torsional damper second torsional damper nonelastomeric bonding surface, and said second elastomeric torsional damper first torsional damper nonelastomeric bonding surface rotating relative to said second elastomeric torsional damper second torsional damper nonelastomeric bonding surface.
