Abstract
A turbo-machine casing comprises a part double skinned portion at a location surrounding at least one stage of rotor blades; the spaces defined between the two skins containing a heat insulating medium, and the inner of the two skins being additionally provided upon its radially innermost surface with a lining of heat insulating material, the casing being connected to a mass disposed radially outwardly of the casing whereby the rate of thermal expansion of the casing can be reduced nearly equal to the bladed rotor which it surrounds.
