摘要： An active bypass flow control system for controlling bypass compressed air based upon leakage flow of compressed air flowing past an outer balance seal between a stator and rotor of a first stage of a gas turbine in a gas turbine engine is disclosed. The active bypass flow control system is an adjustable system in which one or more metering devices may be used to control the flow of bypass compressed air as the flow of compressed air past the outer balance seal changes over time as the outer balance seal between the rim cavity and the cooling cavity wears In at least one embodiment, the metering device may include an annular ring having at least one metering orifice extending therethrough, whereby alignment of the metering orifice with the outlet may be adjustable to change a cross-sectional area of an opening of aligned portions of the outlet and the metering orifice.

摘要： Thermoacoustic sensors, such as dynamic pressure sensors, in the combustor measure vibratory responses of the combustor. An integrated monitoring and control system controller correlates sensor readings with combustion thermoacoustic properties in order to identify combustion anomalies by wavelet or Fourier analysis techniques; determine bulk temperature characteristics within the combustor with dominant mode frequency analysis techniques; and optionally determines absolute active path temperatures within the combustor with acoustic pyrometry transmission and time-of-flight analysis techniques. In some embodiments all of the monitoring functions are performed with a commonly shared array of thermoacoustic sensors that function as both combustion dynamics thermoacoustic vibration/wave receivers and acoustic transmitters. The monitored combustion properties are used for controlling gas turbine combustion.

摘要： Broken remnants of turbine engine rotor thru-bolt/nut interfaces are enveloped in a housing that is coupled to the rotor, so that the remnant does not migrate to other portions of the engine. In exemplary embodiments the housing directly mates with and engages the thru-bolt stud male threaded portion that projects outwardly from the nut, such as by a female threaded sleeve that is engaged with the male threads. The sleeve is in turn coupled to and/or supported by the rest of the housing. Some housing embodiments surround one or more of the threaded stud/nut interfaces. Housing embodiments of the invention are installed in situ without removing the rotor structure from the engine.

摘要： Inspecting a retaining ring of a dynamoelectric machine includes placing an optical device in a stationary component of the dynamoelectric machine and directing the optical device toward a radial view of the retaining ring. An image is obtained and transmitted of a circumferential portion of the retaining ring, using the optical device during rotation of the rotor. Identification is made of a location of one or more stress cracks forming and visible at the circumferential portion of the annular edge. Further, a structural condition is determined for at least one location on the retaining ring using a metric to identify a value of the metric exceeding a predetermined acceptable value of the metric.

摘要： A gas turbine combustor for producing hot gas by burning a fuel in compressed air comprising a combustor central axis and multiple main swirlers with respective swirler axes disposed about and parallel to the combustor central axis, each main swirler delivering an air fuel mixture flowing through it and about its swirler axis, wherein each swirler imparts rotation to the air fuel mixture flowing through it in a direction opposite that of adjacent swirlers. This combustor configuration reduces shear where the outer edges of adjacent flows meet, allowing for greater tuning of the combustion chamber and reduced NOx and CO emissions.

摘要： A turbine blade includes an airfoil and a shroud coupled to a tip of the airfoil. The shroud includes a mid portion positioned directly above the tip of the airfoil. The mid portion includes a ramped radially outer surface extending from a first edge to a second edge in the direction from a pressure side toward a suction side of the airfoil, the second edge being positioned further radially inward than the first edge. In a first aspect, the shroud may include a curved pressure side portion positioned upstream of the pressure side of the airfoil, the pressure side portion being curved radially inward. In a second aspect, the shroud may include a curved suction side portion positioned downstream of the suction side of the airfoil, the suction side portion being curved radially outward.

摘要： A turbine engine blade removal apparatus with a pair of opposed outwardly biased blocks are positioned proximal a blade root and corresponding rotor disc slot between opposed axial faces of the subject first rotor disc and an adjoining second rotor disc. The blocks are outwardly biased in abutting contact with first and second rotor disc axial faces, aligning an aperture of a guide bushing with an exposed axial face of the blade root, the guide bushing coupled to at least the first block. A punch is inserted in the guide bushing aperture so that a punch tip is in abutting relationship with the blade root axial face. An impact tool drives an opposite impact end of the punch, causing the punch to direct a relative driving force on the blade root, separating the blade root from the corresponding rotor disc slot.
