What tool is used to accomplish internal inspection of an assembled turbine engine?

The tool that is specifically designed for internal inspection of an assembled turbine engine is the borescope. A borescope is an optical device that allows technicians to visualize the internal components of engines without requiring disassembly. It consists of a long, flexible or rigid tube with an integrated camera and/or lens system, which can illuminate dark engine interiors and provide a clear view of areas that are not accessible otherwise.

Using a borescope is crucial for conducting inspections on turbine engines, especially in relation to detecting wear, corrosion, or damage to critical components such as turbine blades, combustion chambers, and other internal parts. This non-destructive testing method ensures that technicians can assess the condition of the engine, identify potential issues early, and maintain safety and performance standards effectively.

Other tools mentioned, such as endoscopes and laser imaging, are not specifically tailored for the unique requirements of turbine engine inspection. Pressure transducers are used for measuring the pressure within systems but do not provide visual inspection capabilities. Thus, the borescope stands out as the optimal choice for such inspections.
