Tool and method for inspecting an annular space of an engine

A tool for inspecting an annular section of an engine, the tool comprising:

• a first segment extending along a first lengthwise direction between a forward end and an aft end and wherein the first segment defines an outer side and an inner side;
• a second segment extending along a second lengthwise direction between a forward end and an aft end and wherein the second segment defines an outer side and an inner side, the forward end of the first segment pivotably coupled to the aft end of the second segment at a pivot axis at the respective outer sides of the first segment and the second segment, and the first segment moveable relative to the second segment between a bent position and a coupled position, the first lengthwise direction defining a coupled angle with the second lengthwise direction when the first segment is in the coupled position relative to the second segment;
• an adjustment member operable with the first segment, the second segment, or both to adjust the coupled angle defined by the first lengthwise direction with the second lengthwise direction and wherein the adjustment member is coupled to the inner side of the first segment, the inner side of the second segment, or both;
• and
• a third segment extending along a third lengthwise direction between a forward end and an aft end, the forward end of the second segment pivotably coupled to the aft end of the third segment, the second segment moveable relative to the third segment between a bent position and a coupled position, the second lengthwise direction defining a coupled angle with the third lengthwise direction when the first segment is in the coupled position relative to the second segment.

• and
• an insertion tube defining a substantially 90 degree bend, wherein the first segment and the second segment are moveable through the insertion tube, and wherein the first segment is positioned in the bent position relative to the second segment when moved through the substantially 90 degree bend of the insertion tube.
