Abstract
A helicopter rotor damper system including a torsional damper with a damper centering bearing providing a damper center of rotation axis, a first elastomeric torsional damper with 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, and a second elastomeric torsional damper with 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. The helicopter rotor damper system includes a damper link linked with the torsional damper, with the torsional damper and the damper link connected between a helicopter blade and a helicopter rotor with the elastomeric torsional damper nonelastomeric bonding surfaces relatively rotating.
