Abstract
A casing support structure for a gas turbine engine is provided with means for reducing the effect of distortions such as are produced by differential heating of the structure on shut-down. To this end the casing is mounted from supporting structure by links which are arranged to be individually heated by associated heaters. The degree of heating of the links is arranged to provide differential expansion which moves the casing so as to reduce the effect of eccentricities on the clearance between the casing and its associated rotor structure.
