Fiber-optic-coupled differential-pressure transducers are being developed for use in hot, harsh environments like those in the cores of aircraft turbine engines. The prior approach to the measurement of pressures in such engines involves the use of pressure transducers coupled to pressure taps via long tubes, which introduce delays and degrade responses to high-frequency pressure variations. In contrast, the fully developed versions of the developmental transducers would be mounted directly in the affected compressor, combustor, and turbine stages; because there would be no long pressure-coupling tubes, these pressure transducers would yield more-accurate readings in more nearly real time. The readings could help to identify conditions that must be corrected in maintenance work and could, potentially, enhance safety in flight by providing indications of impending compressor stall.
