Dual-Intent Locator Pin and Removable Plug for Gas Turbines

A gas turbine engine comprising:

• a plurality of bores through a first gas turbine engine structure, the bores equally spaced around a circumference of a gas turbine engine;
• a plurality of pins adapted for insertion into the bores to couple the first gas turbine engine structure to a second gas turbine engine structure;
• an inspection path defined through one of the bores, the second gas turbine engine structure, and an opening into a gas path of the gas turbine engine;
• and
• a removable plug for insertion into the inspection path, the removable plug adapted to couple the first gas turbine engine structure to the second gas turbine engine structure.

A method for constructing a borescope plug assembly within a gas turbine engine comprising:

• providing a gas turbine engine with a plurality of bores through a first gas turbine engine structure, the bores equally spaced around a circumference of a gas turbine engine, and a plurality of pins adapted for insertion into the bores to couple the first gas turbine engine structure to a second gas turbine engine structure;
• defining an inspection path through at least one of the bores, the second gas turbine engine structure, and an opening into a gas path of the gas turbine engine;
• and
• inserting a removable plug into the inspection path, the removable plug adapted to couple the first gas turbine engine structure to the second gas turbine engine structure.
