Abstract

This work demonstrates a 1000°C capable fiber optic (Wave-Phire™) sensor for gas turbine engine control and health monitoring. This fiber optic pressure sensor can be further developed for flight applications and is amenable to miniaturized (integrated optic) interrogation. The sensing and interrogation technology are both suitable for wide application beyond the engines in other parts of the aircraft, even when high temperatures are not required.
