    Abstract: A heat shield (44) for an external component, such as a gearbox (42), of a gas turbine engine (20) for limiting heat transfer from the engine (20) to the external component is disclosed. The heat shield (44) may be formed to the shape of the gearbox (42) to reduce the geometric envelope of the gearbox (42) and heat shield (44). The heat shield (44) may be formed by a thin thermal insulation core (50) surrounded by a metal sheet (51). The small thickness of the heat shield (44) also reduces the geometric envelope of the heat shield (44). Since no extra equipment is needed to provide cooling fluid to the gearbox (42), the heat shield (44) reduces the overall weight of the gas turbine engine (20) as well.

    Abstract: A turbine engine assembly includes a turbine engine case, a gearbox and a plurality of mounts connecting the gearbox to the case. Each of the mounts includes a linkage and a fuse joint. The linkage extends towards the case substantially in a first direction. The fuse joint is configured to substantially prevent movement between the gearbox and the case when the fuse joint is subject to loading less than a threshold, and to permit a constrained movement between the gearbox and the case when the loading is greater than the threshold. The fuse joint of a first of the mounts has a different configuration than the fuse joint of a second of the mounts.
