An in-situ system for a gas turbine engine blade inspection including a sensor system configured to capture images of a forward surface of at least one gas turbine engine blade; a processor coupled to the sensor system, the processor configured to determine damage to the at least one gas turbine engine blade based on video analytics; and a tangible, non-transitory memory configured to communicate with the processor, the tangible, non-transitory memory having instructions stored therein that, in response to execution by the processor, cause the processor to perform operations comprising receiving, by the processor, data for the forward surface of at least one gas turbine engine blade from the sensor system; determining, by the processor, a rotational speed of a fan; and determining, by the processor, a fan synchronization.

An assembly for an aircraft propulsion system includes a propulsor section, an imaging device, a plurality of light sources, and a controller. The propulsor section includes a propulsor. The propulsor includes a plurality of propulsor blades. The imaging device is disposed in the propulsor section. The imaging device includes a camera. The plurality of light sources are disposed in the propulsor section. The controller includes a processor in communication with a non-transitory memory storing instructions, which instructions when executed by the processor, cause the processor to: control the plurality of light sources to direct light to the plurality of propulsor blades, control the camera to capture image data of each propulsor blade of the plurality of propulsor blades, and identify a presence or an absence of damage for each propulsor blade of the plurality of propulsor blades using the image data.

A method is provided for an engine. During this method, a saturation current of a gas flow is measured. The gas flow includes combustion products generated by the engine. The saturation current is monitored to determine presence of debris entrained within the gas flow.

Detecting engine exhaust debris using saturation current

A method of inspecting blades of a gas turbine engine for abnormalities includes projecting light from a light source into an illumination area; utilizing a sensor to record data of at least one reflection of the projected light from a blade that is part of a gas turbine engine and is disposed in the illumination area; determining, based on the recorded data, whether the blade is abnormal; and based on the determining indicating that the blade is abnormal, providing a blade abnormality notification. A gas turbine engine is also disclosed.

A fuel gas removal system includes a venturi for reducing a pressure of the fuel, a bubble separator containing media to assist in the formation of gas bubbles within the fuel to separate the gas bubbles from the fuel, and a port to remove gas bubbles created by the reduction of pressure of the fuel and the bubble separator.
