The document discusses next generation aircraft engine evolution to meet growing global air transportation demand. It summarizes commercial engine industry growth projections showing a 38% increase in engines from 2012 to 2022. It also outlines the International Aircraft Engine Association's (IAEA) vision to promote global collaboration across the aircraft engine industry through initiatives like common contracts, an ecommerce platform, and an integrated aircraft engine engineering curriculum. Finally, it discusses various technical challenges for next generation engines like larger fan sizes, fan drive systems, higher temperature materials, and modular design considerations.
