    Abstract: An aerodynamic seal assembly for a rotary machine is provided. The assembly includes multiple sealing device segments disposed circumferentially intermediate to a stationary housing and a rotor. Each of the segments includes a shoe plate with a forward-shoe section and an aft-shoe section having multiple labyrinth teeth therebetween facing the rotor. The shoe plate is configured to allow a high pressure fluid to a front portion of the plurality of the labyrinth teeth and a low pressure fluid behind the plurality of the labyrinth teeth and further configured to generate an aerodynamic force between the shoe plate and the rotor. The sealing device segment also includes multiple bellow springs or flexures connected to the shoe plate and to a top interface element, wherein the multiple bellow springs or flexures are configured to allow the high pressure fluid to occupy a forward cavity and the low pressure fluid to occupy an aft cavity. Further, the sealing device segments include a secondary seal attached to the top interface element at one first end and positioned about the multiple bellow springs or flexures and the shoe plate at one second end.

    Abstract: The invention relates to a method for determining the size of a radial gap between rotating and torsion-proof parts, particularly the parts of a turbomachine. According to said method, an original signal emitted by a transmitter device located on the surface of the rotating part is received in a modified manner by a receiver device disposed on the torsion-proof part and is redirected to an evaluation unit. Said evaluation device determines and displays the size of the radial gap from the received signal by determining the parameters of the trajectory of the rotating transmitter device.

    Abstract: A method enables a gas turbine engine compressor including a stator assembly and a rotor assembly to be assembled. The method comprises providing a casing formed from a plurality of rings, and coupling a first of the casing rings around the rotor assembly such that a radially inner surface of the first casing ring is axially aligned with, and radially outward from, a row of rotor blades extending from the rotor assembly. The method also comprises coupling a second of the casing rings to the first casing ring with a fastener assembly, such that the first casing ring radially inner surface facilitates insulating the fastener assembly from the compressor flowpath.

    Abstract: A gas turbine engine having a housing and an axially extending shaft journaled to the housing by two axially spaced apart bearings. The bearings are located along the shaft so as to define an overhung shaft portion. A rotating component such as a turbine wheel or compressor wheel is mounted on the overhung shaft portion and is concentric about the centerline of the engine. An annular shroud that is part of the housing is disposed about the rotating component, the annular shroud being concentric about a centerline radially offset from the engine.
