High Temperature Optical Fiber Instrumentation for Gas Flow Monitoring in Gas Turbine Engines
Abstract
Fiber optic sensors have now been used for medical, chemical and biomedical applications and to measure pressure, temperature and strain in a number of different industries. In order to use one of the techniques utilized in fiber optic sensing, a design must be chosen which is capable of making absolute measurements with a high accuracy, and high data rates. The sensor technology chosen here is the self-calibrated interferometric/internality-based (SCIIB) optical fiber sensor. This document discusses the initial stages of the development of an SCIIB system to meet the requirements for pressure measurement in gas turbine engines. It was possible to show that a tube-based sensor could be modified to generate an increased frequency response, however it came at the cost of increased temperature sensitivity and a lack of repeatable results.
