What is borescope turbine inspection?
Gas Turbine Borescope Inspection. Borescope inspection of gas turbine can help view and access impossible or hard to reach areas. Gas turbines operate at the extremely high temperatures, hence professional assistance is necessary for safe NDT (Nondestructive Testing) and RVI (Remote Visual Inspection).
What is a borescope inspection on aircraft engine?
Borescope inspections are a type of visual inspection that can examine hard-to-reach or inaccessible components without taking them apart or damaging them.
What tool is used for turbine section inspection?
Rigid borescopes are used when the area to be inspected is reachable in a straight path, as in many machined parts, tubes, and some moulded parts. For many turbine blades and combustion chamber inspections, a rigid borescope is the best bet.
What are some of the tell tale signs of damage that should not be ignored during the borescope inspection?
During inspection with tools like an aviation borescope, the operator can spot issues that indicate future, or imminent failure….Don’t Ignore These Signs
- Wear of Components.
- Poor Lubrication.
- Contaminated Fluids.
- Leaks.
- Cracks.
- Corrosion.
When carrying out a borescope the damage on turbine blades that would indicate a failure is?
32. . When carrying out a borescope the damage on turbine blades that would indicate a failure is. Option A. speckling.
What items are checked in a hot section inspection of a turbine engine?
A hot section inspection (HSI) involves examining the condition of a number of key engine parts, including the turbine blades, the combustion chamber, the stators, the vane rings, the compressor turbine disk and the shroud segments. A hot section inspection is performed on a PT6 engine.
What will happen if one compressor blade of the turbine engine is missing?
Failure of any blade or vane can lead to severe collateral damage in both the compressor and turbine section of the engine. Root cause analyses (RCA) often find foreign and domestic object damage and operational issues as among the usual suspects.
