<P>PROBLEM TO BE SOLVED: To provide a load reduction system used in a supporting system for a fan assembly of an engine. <P>SOLUTION: A rotor decoupler system includes the load reduction system 60 disposed between a bearing system and a bearing support. The load reduction system includes a fuse 75 and a damper 71, and the damper transfers at least a part of a radial load from the rotor to the bearing support 70 when a fuse fails. In one exemplary embodiment, the damper includes a wire mesh disposed around the outer race of the bearing. In another exemplary embodiment, the damper includes a rope damper assembly. In further another exemplary embodiment, the load reduction system is disposed between a support structure and a frame, includes a damper disposed between an extensional fuse and the support structure. The damper transfers at least a part of an unbalance load to the frame when the extensional fuse fails. <P>COPYRIGHT: (C)2009,JPO&INPIT |
