Blade defects decrease engine efficiency and power, while increasing fuel burn (specific fuel consumption) and exhaust gas temperature (EGT) - resulting in higher maintenance costs, and decreased aircraft availability. Additionally, defective compressor blades can pose a safety threat if not replaced in a timely manner. While researching areas for increased aircraft optimization, Air Force Operational Energy found that cost-effective and reliable blade inspection ensures engines are performing optimally, and is paramount to maintaining aircraft readiness.
