ABSTRACT:
Tiltrotor aircraft drivelink includes a nonelastomeric outer drivelink member with a first linkend and a distal second linkend. The tiltrotor aircraft drivelink first linkend has a first linkend cavity with a first linkend cavity inner circumferential bonding surface, and a first linkend nonelastomeric inner member contained in the first linkend cavity, the first linkend nonelastomeric inner member having a first linkend outer circumferential bonding surface, and a first linkend elastomeric intermediate having an outer circumferential elastomeric bonding surface and an inner circumferential elastomeric bonding surface, the outer circumferential elastomeric bonding surface bonded to the first linkend cavity inner circumferential bonding surface and the inner circumferential elastomeric bonding surface bonded to the first linkend outer circumferential bonding surface, the elastomeric intermediate containing N nonelastomeric outboard bonded shims and no more than N−1 nonelastomeric inboard bonded shims. The tiltrotor aircraft drivelink second linkend has a second linkend cavity with a second linkend cavity inner circumferential bonding surface, and a second linkend nonelastomeric inner member contained in the second linkend cavity, the second linkend nonelastomeric inner member having a second linkend outer circumferential bonding surface, and a second linkend elastomeric intermediate having an outer circumferential elastomeric bonding surface and an inner circumferential elastomeric bonding surface, the outer circumferential elastomeric bonding surface bonded to the second linkend cavity inner circumferential bonding surface and the inner circumferential elastomeric bonding surface bonded to the second linkend outer circumferential bonding surface, the second elastomeric intermediate containing N nonelastomeric outboard bonded shims and no more than N−1 nonelastomeric inboard bonded shims.
