Abstract

A flash thermography device for generating an infrared image of each of a plurality of rotating turbine components located within a turbine. The device includes infrared sensors for detecting thermal energy radiated by each component. The apparatus also includes a borescope having a viewing end positioned on the longitudinal axis of the borescope. The borescope is positioned in the inspection port to position the viewing end inside the turbine such that at least one component is within the field of view of the viewing end. Additionally, the device includes a flash source that generates a plurality of light pulses corresponding to the number of components rotating during a single rotation of the rotor, wherein the light pulses are oriented substantially transverse to the longitudinal direction. Thermal energy radiated from each component is transferred through the borescope to an infrared sensor to enable the generation of an infrared image.

Description

[0001] Cross References to Related Applications [0002] This application is a continuation in part of 35 U.S.C. § 120 of co-pending U.S. Patent Application No. 14 / 684,471, filed April 13, 2015, entitled "SYSTEM TOPROGNOSE GAS TURBINE REMAINING USEFUL LIFE," which This application is hereby incorporated by reference in its entirety, and this application claims the benefit of priority from the above-mentioned application. technical field [0003] The present invention relates to flash thermography devices used in conjunction with turbines, and more particularly to flash thermography devices having an infrared sensor and a borescope, wherein the borescope is positioned in an inspection port to position the viewing end of the borescope at inside the turbine such that at least one rotating component of the turbine is within the field of view of the viewing end, and wherein the borescope includes a flashlight source that generates a number of light pulses corresponding to the numbe...
