GE Aerospace Bengaluru Engineers Drive CFM RISE Program

Engineers at GE Aerospace’s John F. Welch Technology Centre (JFWTC) in Bengaluru, India, are spearheading the development of Open Fan architecture and hybrid electric systems designed to deliver a 20 percent reduction in commercial aircraft fuel burn.

In an official company article published on August 18, 2026, GE Aerospace detailed the specific contributions of its Indian research and development hub to the CFM RISE program. The engineering push in Bengaluru follows the manufacturer’s recent flight testing milestones, including a transatlantic hybrid electric flight demonstration in July 2026.

Doubling historical efficiency gains

The CFM RISE program targets a significant leap in performance over current-generation powerplants. Previous engine iterations developed by the company, including the GE90, GEnx, GE9X, and CFM LEAP, each delivered fuel efficiency improvements of 10 to 15 percent.

Nitesh Jain, a consulting engineer with 26 years at GE Aerospace, noted that the current development cycle aims to double those historical margins. Achieving a 20 percent improvement requires fundamental changes to engine design rather than incremental updates to existing turbofan models.

“We found the only way to get this kind of step change in fuel-burn efficiency without excessive weight and drag is to remove the constraints of the engine’s cover,” Jain stated in the company release.

The resulting Open Fan architecture relies on a combination of advanced aerodynamics, thermal systems design, and additive manufacturing. Jain indicated that these disciplines must work in concert to meet future commercial aviation demands for operability, durability, and manufacturability.

Scaling hybrid electric power for high altitudes

Alongside the Open Fan design, the Bengaluru team is adapting megawatt-scale hybrid electric systems for commercial aircraft. A primary technical hurdle involves engineering electrical components that can function reliably above 30,000 feet.

Sumitha Mohan, a senior engineer who has spent four years adapting hybrid electronics for aircraft, highlighted the distinct challenges of aerospace applications compared to terrestrial electric vehicles.

“Cars are designed to operate at sea level, at normal temperatures, with relatively few weight demands. With aircraft, you need systems as power-dense as possible, so as not to negatively affect fuel burn, and that can operate at high ambient conditions,” Mohan explained.

The integration efforts in Bengaluru directly supported recent flight tests of GE Aerospace’s modified Electrified Powertrain Flight Demonstration (EPFD) aircraft. In May 2026, the EPFD testbed completed the world’s first high-altitude hybrid electric flight. Two months later, in July 2026, the aircraft crossed the Atlantic Ocean en route to the Farnborough International Airshow, demonstrating the viability of integrating a megawatt-class hybrid system with existing onboard electrical networks.

The detailed spotlight on the John F. Welch Technology Centre underscores a broader industry shift toward distributed, globalized research and development. As engine manufacturers approach the thermodynamic limits of traditional enclosed turbofans, achieving the 20 percent efficiency target of the CFM RISE program requires concurrent breakthroughs in materials science, aerodynamics, and electrical engineering.

We view the successful high-altitude and transatlantic flights of the EPFD aircraft as critical validation points for GE Aerospace. However, transitioning these megawatt-scale hybrid systems from a modified testbed to a certifiable, production-ready commercial airliner will require sustained engineering investment. The work emerging from Bengaluru indicates that GE Aerospace is positioning its international engineering hubs to carry a substantial portion of that developmental load.
