Abstract:

This design manual contains the recommended analytical approaches and engineering procedures to be followed by designers of elastomeric bearings for rotor head applications in helicopters. Three bearing configurations, namely, axially laminated cylindrical Type I, radially laminated cylindrical Type II , and spherical laminated Type III bearings are considered. Several levels of design analysis are presented closed-form operations, computer-developed design curves, and finite-element computer analysis. The design restraints determined by stability and service life are also considered. The material properties required for the design and the suggested experimental methods for their determination are also discussed.
