摘要： A system for detecting the presence of an anomaly within a component includes a motorized apparatus configured to move around the component. The system also includes an excitation device and a camera mounted to the motorized apparatus. The excitation device is configured to emit an excitation signal toward the component to cause the anomaly within the component to generate a detectable reactionary thermal signal in response to the excitation signal. The camera is configured to capture thermal images of the component. The thermal images include the detectable reactionary thermal signal and indicate the presence of the anomaly within the component. The system further includes a controller communicatively coupled to the excitation device and the camera. The controller is configured to receive and analyze the thermal images to detect the presence of the anomaly within the component. The controller is configured to adjust one or more operating parameters of the system to affect a characteristic of the detectable reactionary signal based on the thermal images.

The plenum housing includes an interior plenum that receives the two-phase mixture of ceramic-liquid droplets in the carrier gas from the atomizing zone housing. The device also includes one or more delivery nozzles fluidly coupled with the plenum chamber. The delivery nozzles provide outlets from which the two-phase mixture of ceramic-liquid droplets in the carrier gas is delivered onto one or more surfaces of a target object as the coating on the target object.

摘要： A system for on-line optical monitoring of a gas turbine engine includes a viewport into a combustor of the gas turbine engine and an optical filter optically coupled to the viewport. The optical filter is configured to receive broad wavelength band thermal radiation from an interior surface of the combustor while the gas turbine engine is in operation, to substantially block wavelengths of the broad wavelength band thermal radiation emitted and/or absorbed by a flame and/or by exhaust gas within the combustor, and to output narrow wavelength band thermal radiation from the interior surface of the combustor. The system also includes a detector array in optical communication with the optical filter. The detector array is configured to receive the narrow wavelength band thermal radiation and to output signals indicative of a two-dimensional intensity map of the narrow wavelength band thermal radiation.
