The brief

Analyst view

• CFM is jointly owned by GE Aerospace and Safran Aircraft Engines with roughly $1B+ annual revenue.
• The RISE program has completed approximately 500 test campaigns across five years, with designs targeting the A320 successor due in 2030s.
• Ground and flight tests of the open-fan architecture are planned this decade, with Airbus testing on an A380 in 2029.

Technical approach

As reported

Open Fan

Eliminating the engine casing

The open-fan design removes the traditional ducted casing around the fan, allowing larger fans that reduce drag and improve efficiency.

Compact Core

Smaller, hotter core

A compact core burns fuel more efficiently by operating at higher temperatures and pressures, reducing fuel consumption.

Hybrid-Electric

Electric motors on shafts

Electric machines on high and low-pressure shafts extract or deliver power, enabling hybrid operation.

Sustainable Fuels

Compatible with SAF and hydrogen

RISE engines are designed to work with Sustainable Aviation Fuel (SAF) and hydrogen, meeting future aircraft decarbonization goals.
