Development of High-Temperature Wiring for Engine Bays

Condition monitoring of the components of the gas turbine engine is essential. Gas turbine engines are being designed to run at sustained high temperature conditions. The limiting factor to the implementation of the control and diagnostic capabilities for health (condition) monitoring are not the devices themselves, but the temperature capability of the associated wiring. UES, Inc., in collaboration with Astro Industries, proposes to select, design and fabricate high-temperature wiring capable of sustaining the high-temperature engine environment. The suitability of the selected wire components and the complete wire in the high-temperature engine environment will be demonstrated and ranked. The highly ranked high-temperature wires will be further developed in Phase II. Also in Phase II, the developed wiring system will be integrated with the developing sensor and their suitability in the high-temperature environment will be evaluated.
