A mounting assembly for mounting an auxiliary component to an engine case of a gas turbine engine, the engine case extending along an axial direction with respect to a central rotational axis of the gas turbine engine and extending along a lateral direction with respect to the central rotational axis of the gas turbine engine, comprising:
- a first flange configured for attaching the mounting assembly to the engine case;
- a second flange configured for attaching the mounting assembly to the auxiliary component;
- and
- a mechanical fuse disposed between the first flange and the second flange and configured to shear during an overload event, the mechanical fuse includes:
- a center portion connected to the second flange and extending away from the second flange and toward the first flange, the center portion defines a rectangular block bounded by a first lateral side and a second lateral side;
- a first fuse member spaced a first lateral distance from the first lateral side;
- and
- a second fuse member spaced a second lateral distance from the second lateral side.
A gas turbine engine, comprising:
- an engine case, the engine case including a plate for mounting a gearbox;
- and
- a mounting assembly for mounting the gearbox to the engine case, the engine case extending along an axial direction with respect to a central rotational axis of the gas turbine engine, the mounting assembly including
- a first flange configured for attaching the mounting assembly to the engine case,
- a second flange configured for attaching the mounting assembly to the gearbox, and
- a mechanical fuse disposed between the first flange and the second flange and configured to shear during an overload event, the mechanical fuse includes:
- a center portion connected to the second flange and extending away from the second flange and toward the first flange, the center portion defines a rectangular block bounded by a first lateral side and a second lateral side;
- a first fuse member spaced a first lateral distance from the first lateral side;
- and
- a second fuse member spaced a second lateral distance from the second lateral side.
