Abstract: A turbine engine assembly includes a turbine engine case, a gearbox and a plurality of gearbox mounts that connect the gearbox to the case. The case extends along an axis between an upstream end and a downstream end. The gearbox mounts include an axial mount that extends axially in an upstream direction from the gearbox to the case.

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 translation: 公开了一种用于限制从发动机（20）到外部部件的传热的燃气涡轮发动机（20）的外部部件（例如齿轮箱）的隔热罩（44）。 隔热罩44可形成为齿轮箱42的形状，以减小齿轮箱42和隔热罩44的几何外形。 隔热罩44可以由被金属板51包围的薄的保温芯50形成。 隔热罩（44）的小厚度也减小了隔热罩（44）的几何外形。 由于不需要额外的设备来向齿轮箱（42）提供冷却流体，所以隔热罩（44）也降低了燃气涡轮发动机（20）的总重量。

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.
