摘要： A temperature measurement system includes at least one filament configured to emit thermal radiation in a relatively broad and substantially continuous wavelength band that is at least partially representative of a temperature of the at least one filament. The system also includes an optical system configured to receive at least a portion of the thermal radiation emitted from the filament. The optical system includes a wavelength splitting device configured to split the emitted thermal radiation into at least one relatively narrow wavelength band of thermal radiation. The optical system also includes a detector array configured to receive the at least one relatively narrow wavelength band of thermal radiation and to generate electrical signals at least partially representative of the received thermal radiation. The temperature measurement system further includes a controller communicatively coupled to the detector array. The controller is configured to transform the generated electrical signals to a temperature indication using a predetermined conversion module.

摘要： The present invention provides a cooling apparatus for cooling a turbine blade. The cooling apparatus comprises a pressure side plate comprising a plurality of pressure ribs, a suction side plate comprising a plurality of suction ribs, and a plurality of flow redirection areas. The pressure side plate is disposed over the suction side plate, where the pressure ribs are disposed at a first angle with respect to a blade span reference line and the suction ribs are disposed at a second angle with respect to the blade span reference line, to form the flow redirection areas. The present invention provides a method of fabricating the cooling apparatus for the turbine blade comprising aligning the pressure side plate and the suction side plate to form the plurality of flow redirection areas between the pressure side plate and the suction side plate.

摘要： A thermal inspection method is provided for a component comprising at least one complex internal passage arrangement defining at least one opening. The thermal inspection method includes flowing a fluid through the at least one complex internal passage arrangement.
