Turbine Compressor Blade Evaluation – Phase II

NCMS Project #: 141031

Problem: As in the commercial industry, compressor airfoils in military gas turbine engines operate in both erosive and corrosive maritime environments.  For commercial and military aircraft engines and their relevance to safety, reliability and sustainability, a protective layer capable of resisting erosion and corrosion is sorely needed.  

Benefit: This explicit testing will show how the application of improved erosion controls on compressor blades for the AGT 1500 can reduce erosion under harsh conditions and will serve as an example of how to maintain airfoil integrity across the broad spectrum of gas turbine engines.  

Solution/Approach: Phase II will expand upon the accomplishments of Phase I, by utilizing specific rig-testing procedures to deliver practical application data for analysis.  The operating characteristics of the axial and axial-centrifugal compressor under adverse conditions of entrained contaminants, transient throttle position, and auxiliary loads are to be further quantified in Phase II to demonstrate the benefits of maintaining the integrity of the compressor airfoil properties.
