ABSTRACT:
A pair of upper isolators (30) are vertically aligned with a pair of lower isolators (30). The isolators (30) in each pair are spaced horizontally. Each isolator (30) connects and extends between a rear mount bulkhead (16) that is part of a strut (10) and an auxiliary bulkhead (18) that is attached to the aircraft engine (6). The isolators (30) are flexible in a vertical direction to isolate vertical vibrations and are stiff in a lateral direction to resist side loads and engine roll torque. Instead of pairs of isolators (30), a single upper isolator (30b) and a single lower isolator (30b) may be provided. Longitudinally spaced isolators (30) may be formed by stacks (32) of metal plates that bend under vertical loads and resist side loads and torque in shear. Laterally spaced isolators (30e, 30e') resist side loads and torque in tension/compression and isolate vertical loads by bending or in shear. The stacked metal plates of an upper isolator (30d ) and an aligned lower isolater (30d) may be formed by wall portions of nested rectangular tubes (52d, 54d).
