Embodiment Construction

[0060] In the following specification and claims, a certain number of terms will be mentioned, which shall be defined to have the following meanings.

[0061] The singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise.

[0062] "Optional" or "optionally" means that the subsequently described event or circumstance can or cannot occur, and that the description includes instances where the event occurs and instances where it does not.

[0063] Approximate language, as used herein throughout the specification and claims, may be used to modify any quantitative expression that is permissible to be varied without resulting in a change in the basic function to which it is related. Accordingly, a value modified by a term or terms such as "about," "approximately," and "approximately" is not to be limited to the precise value specified. In at least some cases, the approximate language may correspond to the precision of the instrument us...

Abstract

The invention relates to a system and method for servicing a turbomachine. A system for use in servicing a turbomachine, the system including a first tubular body including an interior channel, and a second tubular body. The first and second tubular bodies are bendable between a neutral shape and a biased shape. The bodies are bent when in the neutral shape. The second tubular body includes a tip end, and the second tubular body is translatable within the interior channel. The first tubular body and the second tubular body are rotatable to selectively orient the tip end in multiple degrees of freedom. The system also includes a steering cable extending from the tip end, wherein the steering cable biases the tip end for selective orientation in additional degrees of freedom.

Description

technical field [0001] The field of the disclosure relates generally to turbine maintenance, and more particularly to systems and methods for performing maintenance within the confined space of a turbine. Background technique [0002] At least some known turbine engines include a casing and at least one rotor including multiple stages of rotating airfoils, ie, blades, that rotate relative to the casing. Additionally, the casing includes multiple stages of stationary airfoils, ie vanes. The blades and guide vanes are arranged in alternating stages. In at least some known rotating machines, a shroud is provided on the radially inner surface of the stator to form an annular seal around the tips of the blades. Together, the blades, vanes, and shroud define a main flow path within the compressor and turbine sections of the rotating machine. This flow path, combined with the flow path through the combustor, defines a main cavity within the turbine engine. [0003] During opera...
