Abstract: A tip shroud of a bladed rotor can be monitored for integrity using a sensor configured to detect the tip shroud. A signal from the sensor can be monitored and if the magnitude of the signal changes, such as beyond a defined amount, an indication of possible damage can be made. A baseline sensed pattern for a revolution of the tip shroud can be compared to an operation sensed pattern for a subsequent revolution, and the indication of damage can be made if there is more than the defined amount and/or percentage of difference between the patterns.
Abstract translation: 使用被配置为检测尖端护罩的传感器，可以监视叶片转子的尖端护罩的完整性。 可以监测来自传感器的信号，并且如果信号的大小改变，例如超过限定的量，则可以产生可能的损坏的指示。 可以将尖端护罩的旋转的基线感测图案与用于随后旋转的操作感测图案进行比较，并且如果存在超过限定的量和/或图案之间的差异百分比，则可以进行损伤的指示。

Abstract: According to one aspect of the invention a turbine shroud engagement arrangement includes an outer shroud and an inner shroud operably connectable to the outer shroud. The outer shroud has at least one of a channel formed in and a protruding member extending from an inner radial surface thereof. The inner shroud has at least one of a protruding member extending from an outer radial surface thereof that is complementary to the at least one channel of the outer shroud or a channel formed in the outer radial surface that is complementary to the at least one protruding member of the outer shroud. The turbine shroud engagement arrangement is primarily axially slidably engagable and configured to radially support the inner shroud relative to the outer shroud.

Abstract: A method is presented. The method includes selecting a first window of signals and a second window of signals from clearance signals representative of clearances between a rotating component and a stationary casing surrounding the rotating component, determining a first signed average power value corresponding to the first window of signals, and a second signed average power value corresponding to the second window of signals, determining a resultant value based upon the first signed average power value and the second signed average power value, and determining one or more defects or potential defects in the rotating component based upon the resultant value.
