Abstract
A frangible mounting arrangement between a bearing and a bearing support in a gas turbine engine comprises a plurality of frangible bolts connecting mounting flanges of the bearing and the bearing support. The bolts are disposed on a circle. A distance on the circle between a first pair of adjacent bolts is greater than a distance on the circle between a second pair of adjacent bolts. The bolts are configured to break when subjected to a breaking load above a predetermined value. The breaking load results from at least one of a bending moment and a shear load on the mounting flanges. When subjected to the breaking load, the first pair of adjacent bolts breaks before the second pair of adjacent bolts. A method of providing a frangible mounting arrangement between a bearing and a bearing support is also provided.
