Abstract
A casing construction is provided on a gas turbine having a fan downstream of which a precompressor is situated, the precompressor casing being detachably connected with the casing of the compressor which follows the precompressor—viewed in the flow direction. An upstream end section of the precompressor casing is additionally linked to the compressor casing by at least two tension-rod-type tension devices which are situated essentially diametrically opposite one another with respect to the longitudinal axis of the gas turbine. Steel cables are preferably used as the tension devices and are fastened at least on one of the two casings by means of a tension-nut-type end piece. As a result, the precompressor casing can be constructed of a non-high-strength material and, in addition, can be linked by means of several pairs of tension-rod type tension devices to the casing of the compressor.
