A fuel cell system for driving a pipeline transmission device. The fuel cell system may include a fuel cell stack in communication with the pipeline, a turbine engine in communication with the fuel cell stack, and a DC motor in communication with the transmission device.

A measuring system for measuring axial displacement of a tube relative to an axially stationary component in a rotating rotor assembly includes at least one displacement sensor adapted to be located normal to a longitudinal axis of the tube; an insulated cable system adapted for passage through the rotor assembly; a rotatable proximitor module located axially beyond the rotor assembly to which the cables are connected; and a telemetry system operatively connected to the proximitor module for sampling signals from the proximitor module and forwarding data to a ground station.

A new stator core cooling concept is provided that can be implemented with a conventional core structure having cooling ducts interspersed at intervals along the axial length of the stator core. To enhance cooling of the stator coils, the cooling ducts are radially closed off so that cooling air is forced to flow circumferentially, preferably through small holes, channels, or slots, to impinge directly on the armature bar surface. Accordingly, rather than flowing cooling gas through the cooling ducts and immediately discharging it into the annular gap between the rotor and stator, cooled gas flows radially down through the cooling duct and then must flow circumferentially whereupon it impinges directly on the armature bar surface itself.

A turbine casing is provided in two casing halves joined one to the other along a horizontal splitline having flanges with spaced boltholes. A circumferentially extending rib is provided about each casing half at a location just forward of the turbine buckets to minimize or eliminate distortion caused by internal pressure and meridional roll of the casing. One or more axially extending ribs is provided on each casing half. The axial ribs have a radial stiffness which substantially matches the stiffness and thermal response of the flanges.

Casing distortion control for rotating machinery

A cast article having a reinforced structural composite core is disclosed. The cast article includes a structural element which is embedded in the otherwise cast metal article. The structural element is comprised of a metal matrix composite structural core. It includes a plurality of reinforcing fibers within a metal matrix. The fibers are generally a non-metallic material such as a ceramic which degrade at a temperature below the melting temperature of the cast metal comprising the article. The metal matrix composite structural core is encased with a sheath. The sheath, attached to and completely surrounding the core, is made of the same metal as the cast metal article. In a preferred embodiment, the article is a titanium alloy strut for a gas turbine engine.

The present invention is a damper assembly included in a strut on the front frame for a jet propulsion engine. The damper assembly is disposed within the strut for damping vibration of the strut as a result of air stream pressure pulses from first stage fan blades causing strut excitation when the fan blades are operating at least at transonic speeds.
