摘要： A method for operating a debris monitoring system comprises continuously sensing the passage of particulates through a gas turbine engine (12) to produce a time-domain sensor signal. The time-domain sensor signal is Fourier transformed to produce a frequency domain sensor signal. The frequency domain sensor signal is partitioned into bins corresponding to particulate composition categories. At least one feature is identified within each bin, and is used to determine the amount of particulate flow in each particulate composition category.

摘要： A turbine blade damper-seal assembly (28) includes a seal (30) nested within a damper (34) such that both the seal (30) and damper (34) are disposed to provide sealing between adjacent blade platforms (16). The seal traverses a seal slot (50) in the damper (34) and seals the gap between adjacent blade platforms (16) for the full axial length of the neck cavity between adjacent blades (12). The damper (34) is located in an aft most position and includes features to facilitate vibration-dampening performance. The damper (34) also includes features that cause entrapment between blades (12) and therefore avoids the conventionally required protrusions on the blade to retain it in the assembled position.

摘要： A turbine engine section (18) has a stationary vane stage (100) and a rotating blade stage (54, 74). The blade stage (54, 74) is spaced from the vane stage (100) to form an annular chamber therebetween. A manifold (126) delivers a pressurized fluid to the chamber. An outer diameter (OD) sealing means restricts leakage of the pressurized fluid from the chamber. An inner diameter (ID) sealing means restricts leakage of the pressurized fluid from the chamber. A flow guide (146; 358) extends radially between the inner diameter sealing means and the manifold (126). The flow guide (146; 358) bisects the chamber to form a stationary chamber portion and a rotating chamber portion, the rotating chamber portion at least partially along a disk of the first blade stage.
