This steam turbine blade is provided with: a blade body (61) extending in a radial direction and having an airfoil profile in a cross section perpendicular to the radial direction; and a heater (H) including a heating wire disposed so as to extend along a trailing edge (Er) of the airfoil profile in the blade body (61). This configuration makes it possible to further mitigate an efficiency drop due to moisture attached to the surface of the steam turbine blade (60).

A wash optimization system and related methods are provided that increase the efficiency and the effectiveness of engine washes. A system comprising at least one processor receives sensor data representing one or more measured parameters of a turbine engine and determines at least one performance parameter based on the sensor data. The at least one performance parameter represents one or more particulate values associated with the turbine engine. The system generates a health state for the turbine engine based on the at least one performance parameter and generates a wash identifier based on the health state of the turbine engine.

Ice detection test apparatuses, systems, and methods are disclosed. In some cases, ice detection and precautionary system shut-down event reduction systems and related methods are provided. The system utilizes a turbine engine ice detection apparatus that includes and engine pressure simulation device, an air moving device, and a first air pressure sensor associated with the engine pressure simulation device. The embodiment further includes an ice monitor controller that receives inputs from the first air pressure sensor and at least one second sensor located adjacent a turbine engine intake. The ice monitor controller performs comparisons of inputs from these sensors against each other and stored values to determine actual icing conditions then generate warnings on a display to an operator. The exemplary control section has multiple modes including manual, semi-manual and automatic.

There is described a fixture for supporting a plurality of gas turbine engine blades that are to be imaged. The mobile fixture comprises a plurality of interconnected mounts arranged to lie within a common plane, wherein each mount comprises at least one support surface for holding a respective blade. Support surfaces of respective mounts are oriented such that their respective normal vectors have the same angle with respect to the common plane.

The present invention relates to a method for exhausting high concentrations of toxic gases generated during chemical stripping for high-temperature parts of a gas turbine, the method including the steps of: allowing a pair of openable/closable doors mounted on top of a tank whose top is open to accommodate a chemical substance therein to be closed during the chemical stripping so as to close top of the tank; collecting the toxic gases generated from the interior of the tank through hoods located at the inside of the tank; and exhausting the toxic gases to the outside through exhaust pipes mounted on the hoods or collecting the toxic gases to a separate storage tank.

A gas turbine engine according to an exemplary aspect of the present disclosure includes, among other things, a compressor section, a combustor section, a turbine section, and at least one rotatable shaft. The engine further includes a seal assembly having a seal plate mounted for rotation with the rotatable shaft, a face seal in contact with the seal plate at a contact area, and a seal carrier supporting the face seal. Further, in normal operating conditions, the seal plate includes a plurality of tabs configured to separate from a remainder of the seal plate in a worn seal condition in which the seal carrier contacts the seal plate.
