Abstract: A mount assembly for attaching a heat exchanger to a casing of a gas turbine engine comprises a first attachment feature by which in use the mount assembly is attached to the casing and a second attachment feature spaced from the first attachment feature by which in use the mount assembly is attached to the heat exchanger. The first and second attachment features are joined by an elongate member. The assembly is characterised in that the elongate member is significantly larger in a length direction and a height direction than in a thickness direction, so that it is relatively stiff in the length and height directions L, H and relatively flexible in the thickness direction T; the flexibility allowing movement in use within the mount assembly to accommodate differential thermal expansion between the heat exchanger and the casing.

Abstract: The present disclosure relates to a bracket for a gas turbine engine, the bracket comprising an engine fixing for attaching the bracket to the gas turbine engine at a first end of the bracket, a payload fixing for attaching a payload to the bracket at a second end of the bracket; and a box section comprising a first wall having a first curved shape and extending from the first end to the second end, a second wall having a second curved shape and extending from the first end to the second end, and a plurality of separation members arranged to rigidly fix the first wall relative to the second wall.
