Ceramic pedestal and shield for gas path temperature measurement

摘要

A mounting stand for a temperature sensor is disclosed. The mounting stand includes a base, a pedestal, and a shield. The pedestal extends from the base to a pedestal end distal to the base. The pedestal includes a first hollow cylinder shape forming a bore there through. The shield includes a second hollow cylinder shape extending from the base about the pedestal and extending beyond the pedestal to a shield end distal to the base forming a flow region between the pedestal and the shield. The shield also includes a first aspiration hole extending through the second hollow cylinder shape.

主权项

1. A mounting stand for a temperature sensor, the mounting stand comprising:
a base for mounting the temperature sensor to an airfoil of a gas turbine engine, the base including a cylindrical disk for inserting into an embed hole of the airfoil; a pedestal extending from the base to a pedestal end distal to the base at a pedestal length, the pedestal including a first hollow cylinder shape forming a bore there through, the bore being sized to hold the temperature sensor; and a shield including
a second hollow cylinder shape extending from the base about the pedestal and extending beyond the pedestal to a shield end distal to the base forming a flow region with an annular shape between the pedestal and the shield, anda first aspiration hole extending through the second hollow cylinder shape; and wherein the temperature sensor is secured within the bore using a bonding agent, and the temperature sensor is configured to microstructurally change according to a temperature surrounding the temperature sensor wherein the base, the pedestal, and the shield are formed of a ceramic material.
