Resource Abstract

By 2018, GE Aviation had more than 33,000 engines in service, being the world leader in jet engine manufacturing. GE Aviation has manufacturing, engineering and service business units spread around the world, being GEIQ the engineering design campus in Mexico. Among several engineering services GEIQ offers to GE Aviation, there is rotor and turbine life assessment and External Hardware ownership and design, just to mention a few. This paper summarizes the challenges that GEIQ faces when analyzes such external components by Low-Cycle and High Cycle fatigue loads, elastoplastic loads such Fan Blade Out or Burst Pressure, buckling, and the validation process from a simple modal analysis to ping/engine test. It also walks through the FEA evolution from the reliable CFM56 to LEAP and how that 30% efficiency improvement was possible, and gives an insight about some tools that are going to be used in the future such as additive manufacturing and design optimization.
