Abstract: A method and apparatus for cooling the hot gas casing of a gas turbine power plant is disclosed. The apparatus includes a shell which is spaced from but which encompasses the hot gas casing so as to form an air channel about the casing. A compressor provides a supply of cooling air which flows into the air channel through openings in the shell, and which air absorbs heat from the hot gas casing as it flows through the air channel.

Abstract: A method and apparatus for counteracting an axial thrust imparted to a shaft of a fluid turbine is disclosed. The apparatus includes first and second shaft thrust plates affixed to the shaft. A first, stationary axial thrust bearing engages the first shaft thrust plate. A second axial thrust bearing, having components which are axially movable, engages the second shaft thrust plate. The apparatus also includes a system of fluid lines for supplying pressurized fluid to bellows-like thrust chambers in the second axial thrust bearing. The source of the pressurized fluid is fluid compressed by a compressor mounted on the shaft.

Abstract: Turbine blades having heat localization segments, especially for use in gas turbines, are disclosed. The segments are provided with covering elements in the form of thin cover plates that are supported against the blade root. The segments are formed as one piece together with both the actual blade and with reinforcing elements. The segments are used to impede access of a hot working medium to the turbine rotor.

Abstract: A composite support structure for the casing of a rotary machine comprising coupled turbine and compressor units includes a pair of non-articulated multiple bar type pendulum supports upstanding on a support base at opposite sides of and secured to the casing. The load imposed by the casing on the pendulum supports is relieved by a system of vertical adjustable sprung supports extending between the casing and support base, and a pin projecting downwardly from the casing in alignment with a vertical plane through the machine axis is secured to a horizontally positioned flexible membrane which likewise is secured to the support base for securing the casing against movement in any and all directions in a horizontal plane but permitting expansion in a vertical direction. A transverse metallic sheet either slotted or provided with cut-outs is secured between the underside of the casing and support base and accommodates torsion and/or axial expansion of the casing.
