Abstract

An assembly (200) for mounting an auxiliary component to an engine case (110) of a gas turbine engine (100) includes a support bracket (122), the support bracket having a first end (230) configured for attachment to a first flange (232) of the engine case, a second end (236) configured for attachment to a second flange (238) of the engine case, and an intermediate portion (246) located intermediate the first end and the second end; a bearing member (248) disposed within the intermediate portion; a locator (224) disposed within the bearing member; and a frangible ring member (260) disposed between the support bracket and the bearing member, wherein the frangible ring member comprises a porous metal material (e.g., frothed aluminum or thin-walled honey combed aluminum or steel). The frangible material thickness (262) can be set to absorb FBO energy while limiting system displacement during and post FBO event, thus reducing the energy transmitted to an auxiliary component (e.g., a gearbox housing (120)).
