AI Technical Summary

Problems solved by technology

However, routing the rigid yet flexible tubing through the series of slots and holes in the rotor can be difficult and can often result in leaky or broken connections
Also, the use of waveguides limits pressure measurements to static measurements, since waveguides cannot be used to measure dynamic pressure due to the large volume of air between the sensor and the measurement point

Embodiment Construction

[0122] According to aspects of the invention, there is provided a sensor capable of measuring static pressure and / or dynamic pressure content at a point of interest of a rotor of a turbine. The point of concern (or measurement location) is the harsh environment, and the sensor is exposed to high g-loads and extreme temperatures. The sensors and associated electrical leads are each strategically oriented and secured in probe holders that ensure that the sensors can withstand the extreme centrifugal loads of the spinning rotor. Each point of concern requires a unique detector holder design and wire routing strategy. The interface of the probe holder to the main rotor member is designed to transfer gravitational loads and to resolve stress concentrations.

[0123] Each probe holder encapsulates the sensor on the rotor at the point where data acquisition is desired such that a specific high strength surface of the sensor contacts the bearing surface of the probe holder. This arr...

Abstract

A probe holder for turbine engine sensor is related. A turbine (10) is provided and includes a component having a body, which is rotatable about a rotor centerline (122) and which is formed to define a cavity radially proximate to a point of measurement interest (20) defined at a radial distance from the centerline, a sensor (25) to measure a condition at the point of measurement interest (20), a communication system (30) by which condition measurements are transmittable from the sensor (25) to a non-rotating recording system (75) and a probe holder (90) insertible into the cavity to secure the sensor (25) proximate to the point of measurement interest(20).

Description

[0001] Cross References to Related Applications [0002] This application is related to "Sensor With G-Load Absorbing Shoulder" and "Sensor Packaging For Turbine Engine" filed concurrently with this application and entitled "Sensor Packaging For Turbine Engine" Co-pending U.S. Patent Applications for "Communication System For Turbine Engine" and are cross-referenced with these applications, the entire contents of each of which are hereby incorporated by reference. technical field [0003] The subject matter disclosed herein relates to turbine engine sensors, and more particularly, to turbine engine sensors disposed on a rotor at some radial distance from the rotor centerline. Background technique [0004] In a turbine engine, high temperature fluids are channeled through a turbine section where they interact with turbine buckets rotatable about a rotor to generate mechanical energy. The environment within the turbine section and around or on the rotor is therefore characte...
