GE• RISE program progress and technology targets
- GE Aerospace outlined R&D progress on CFM RISE, targeting a 20% fuel-efficiency gain versus current engines.
- Open Fan architecture aims to enable larger fan diameters, lifting thrust while supporting the fuel-burn target.
- Compact-core technology, paired with adaptive-cycle capability, is intended to improve durability while reducing dust ingestion in harsh environments.
- Frontier supercomputer simulations supported an Open Fan aeroacoustics result, favoring uneven outlet guide vane placement to cut noise.
- Engineers reported integration of a megawatt-scale hybrid system designed to operate at altitude, a step toward electrifying aircraft subsystems.
