Compressor Airfoil Protective Coating for Turbine Engine Fuel Efficiency: Demonstrated on the T56, AGT 1500, and T700 Engine Platforms

Abstract

Several DoD weapon systems were experiencing an unacceptable level of erosion and corrosion from operating in austere environments such as Iraq, Afghanistan, and over oceans. Particularly hard hit were engine compressors and compressor blades. The Army, Navy, and Air Force identified the three engines that underwent demonstrations and field evaluations as part of the CTMA initiatives. The AGT1500, T56, and T700 are installed in different platforms (two air and one tactical ground vehicle), yet all were experiencing unacceptable degrees of corrosion and erosion. Findings from the demonstrations and evaluations with the MDS Coatings Technologies (MCT) will each be highlighted within this report. All three projects were in response to engine compressor and compressor blade degradation from operating in excessive amounts of sand, dust, salt, water, volcanic ash, and other natural elements. The compressor and compressor blade degradation increase engine maintenance, fuel consumption and compressor airfoil replacement, which ultimately increases total operational costs. The subsequent erosion and corrosion negatively affected the engine performance, life span, and reliability.
