Abstract
An adapter to permit borescope access inside a gas turbine engine including a compressor stator having a plurality of compressor stator segments comprises a body portion defining a bore extending longitudinally therethrough from a first end to be disposed adjacent to outside surfaces of adjacent compressor stator segments to a second end to be disposed adjacent to inside surfaces of adjacent compressor stator segments. The bore permits a borescope to enter therethrough. The adapter further comprises an attachment portion for circumferentially coupling at least one compressor stator segment to an outer casing of the gas turbine engine.
Claims21
An adapter to permit borescope access inside a gas turbine engine having an outer casing and including a compressor stator having at least one compressor stator segment, the adapter comprising:
- a body portion defining a bore extending longitudinally therethrough from a first end to be disposed adjacent to outside surfaces of the outer casing to a second end to be disposed adjacent to an inside surface of the at least one compressor stator segment, the bore permitting a borescope to enter therethrough;
- and
- an attachment portion for circumferentially coupling the at least one compressor stator segment to the outer casing.
A gas turbine engine comprising:
- a compressor section having an outer casing and including a compressor stator and rotor, the compressor stator including a plurality of compressor stator segments;
- a combustion section communicating with and disposed downstream of the compressor section relative to a direction of airflow;
- a gas turbine section communicating with and disposed downstream of the combustion section relative to a direction of airflow;
- and
- an adapter circumferentially coupling at least one of the compressor stator segments to the outer casing, the adapter including a body portion defining a bore extending therethrough from at least an outside surface to an inside surface of an associated compressor stator segment, the bore permitting a borescope to enter therethrough.
