    • A method is disclosed for assembling a multi-stage compressor or a multi-stage turbine for use in a gas-turbine engine. The method comprises the steps of assembling a rotor drum so as to comprise a plurality of rotor discs 17, 18, and then releasably connecting a plurality of static components 38 to the assembled rotor drum 19, thus forming an intermediate structure. The intermediate structure is then inserted within an outer casing 50, preferably by lowering the outer casing 50 over the intermediate structure, whereafter the static components 38 are fixed to the outer casing 50. The static components 38 are then released from their connection to the rotor drum 19 in order to permit rotation of the drum 19 relative to the static components 38 and the outer casing 50.
    • 公开了用于组装用于燃气涡轮发动机的多级压缩机或多级涡轮机的方法。 该方法包括以下步骤:组装转子鼓以包括多个转子盘17,18,然后将多个静电部件38可释放地连接到组装的转子鼓19上,从而形成中间结构。 然后将中间结构插入外壳50中,优选地通过将外壳50降低到中间结构上方,然后将静态部件38固定到外壳50.静电部件38然后从与转子 鼓19以允许滚筒19相对于静态部件38和外壳50旋转。
