ABSTRACT:
A casing structure for a gas turbine engine comprises an outer load-bearing casing within which is supported an inner casing which forms the static structure of a compressor. Bearing panels carried from the outer casing carry the rotor of the compressor and its associated turbine. In order to mitigate the undesirable consequences of the bending under load of the outer casing, the inner casing is mounted at a forward section by forward mounting means which maintain it concentric with the rotor axis and at a rearward section by rearward mounting means which maintain it parallel with a section of the outer casing which retains its parallelism with the rotor axis even when the casing bends. The forward mounting illustrated is a dogged engagement while the rearward mounting utilizes a parallel series of links as a parallel motion linkage.
