OPEN FAN ARCHITECTURE: A STEP CHANGE IN PROPULSION EFFICIENCY


The pursuit of ever-increasing propulsive efficiency has driven the growth of engine fan diameter in commercial jet engines over the past five decades. This progression is ultimately leading to the open fan concept which is currently the most efficient option to improve the propulsive efficiency of the engine. The advanced open fan architecture to be demonstrated as part of the RISE program will fly at the same speed as current single-aisle aircraft (up to Mach 0.8, or 80 percent the speed of sound) with a noise signature that will meet anticipated future regulations.

ADVANCED TECHNOLOGIES & MATERIALS


Foundational technologies will be developed and will form the basis of any future CFM engine:

Carbon fiber composite blades manufactured with a 3-D weaving process enable a larger fan diameter to improve propulsive efficiency

An advanced compact core that will increase thermal efficiency and significantly decrease fuel consumption

Hybrid electric systems

Advanced metal alloys and ceramic matrix composites will also improve thermal efficiency
