Abstract
Inspection systems for a gas turbine engine (20) are provided. The inspection systems may comprise an inspection port (106), a bore-scope plug (100), a seal seat (108) and a seal (110A/110B). The bore-scope plug (100) may comprise a shaft (102A/102B) having a uniform or stepped profile. The seal (110A/110B) may be a multi-part seal (110A) or a piston seal (110B). Moreover, the bore-scope plug (100) may be configured to support, carry, and/or stabilize one or more internal structures such as, for example, a mid-turbine frame vane 82. In various embodiments, the inspection systems described herein may provide for increased inspection efficiency during development, qualification, maintenance, and event inspections.
