RISE Program testing
Redefining the state of the art
Progress is accelerating for the Revolutionary Innovation for Sustainable Engines (RISE*) technology demonstration program, with more than 250 tests completed and successful and new research partnerships formed as technologies continue to mature on the way to full-scale Open Fan tests.
CFM RISE program activity is now moving from component-level evaluations to module-level tests.
New propulsion technology features
Wind Tunnel tests
- 1:5 scale demo of the Open Fan
- Aerodynamics & acoustics up to SMR cruise speed
- 300+ test hours performed
- Including test with Airbus demonstrator plane wing to optimize aircraft integration
Supercomputing capability
- New capability in last 10 years supports faster, improved design iteration
- Addresses aerodynamic, acoustic performance
- Multiple simulations run on one of world’s fastest supercomputers (Frontier) … awarded additional hours to model aircraft integration
- Correlating with wind tunnel test results
Hybrid electric
Our program objectives integrate multiple electric generators:
- Demonstrate turbofan and electric machine control
- Validate performance modeling
- Mature and demonstrate up to 1MW-class, flight-quality electric power components
- Mature control logic needed to optimize engine performance
Compact core
- More than 3,000 cycles run with high-pressure turbine airfoils
- Dust ingestion testing planned next
- Reflects early focus on durability and reliability of next-generation engine designs
