Abstract
Asymmetric loading within such machines as gas turbine engines can cause distortion of a casing surrounding a rotating assembly. Such distortion may cause rub and therefore inefficient energy usage and shorter operational life. By providing driver armswhich extend from radially extending linksin a first or high pressure compressor inner casingto a second outer casing, compensation for asymmetric loading can be achieved. The casingsare presented upon relatively stable bearing supportsand therefore, reaction loads are compensated for in order to retain concentricity of the casing
