Problems solved by technology

However, the formation of such slots near the rotor bore can create significant stress concentrations on the rotor during operation
Over time, continuous operation with such stresses can lead to rupture of the rotor and / or premature failure of components or systems

Embodiment Construction

[0065] The exemplary methods and systems described herein overcome disadvantages of at least some known probe assemblies and housings, including at least some plugs or bore tubes, for example, used with rotors of turbine engines. More specifically, embodiments described herein provide a probe assembly including a tube connected to at least one flange having a generally oval shape. The shape of the flange facilitates concentric alignment of the tube within the bore defined in the rotating element to substantially prevent relative rotation of the tube during operation of the turbine engine. Furthermore, having an assembly with such a flange enables the rotor bore to be formed without inspection slots, and the assembly enables plugs and / or bore tubes to be used without including any pins and / or slots, thereby enabling The amount of stress concentration induced to the rotor is reduced when compared to at least some known rotors that include plugs or bore tubes.

Abstract

A method of assembling a probe assembly is provided. At least one probe (207) is coupled to an annular tube, wherein the tube includes an interior surface and an exterior surface. The tube also includes at least one first opening (302)that extends between the interior and exterior surfaces and at least one second opening (304)that extends between the interior(201) and exterior surfaces(203). Moreover, at least one annular flange(208,212) is coupled to the tube. The flange has a substantially elliptical shape that facilitates substantially preventing the relative rotation of the tube.

Description

technical field [0001] The field of the invention relates generally to turbine engines, and, more particularly, to probe assemblies that can be used in the rotor of a turbine. Background technique [0002] At least some known power generation systems include at least one component that may become damaged or worn over time. For example, known turbines include components such as rotors that wear over time. Continued operation with a worn rotor may cause additional damage to other components, or may lead to critical fracture of the rotor and / or premature failure of the component or system. As such, routine evaluation and / or testing of turbine engine components is necessary. [0003] Proper instrumentation is necessary to perform this test. For example, sensing instruments such as probes may be used to measure various states of the rotor and / or turbine when inspecting the rotor and / or flow parameters around it. Additionally, at least some known probes may be inserted into ro...
