GE Aerospace secures a NASA contract (HyTEC Phase 2) to enhance aircraft engines for greater fuel efficiency and reduced emissions. The program aims to develop groundbreaking core technologies and evaluate sustainable aviation fuel (SAF) combustion, marking a significant step towards a greener aviation industry.



GE Aerospace has entered Phase 2 of NASA's Hybrid Thermally Efficient Core (HyTEC) program, an endeavor focused on revolutionizing the next generation of commercial aircraft engines. This partnership targets significant advancements in fuel efficiency and emission reduction, crucial for the future sustainability of aviation.

Mohamed Ali, GE Aerospace's VP of Engineering, expressed gratitude for collaborating with NASA, highlighting their mission to redefine flight's future. HyTEC aims to surpass existing propulsion systems, aiming for a substantial leap in fuel efficiency, a critical factor in reducing environmental impact.

Phase 2 will witness the development of core technologies for a demonstrator test. The evaluation will include the combustion of 100% Sustainable Aviation Fuel (SAF) and advancements in hybrid electric systems integration—a move toward more electric engines.

This initiative aligns with NASA's Sustainable Flight National Partnership, contributing to the United States' goal of achieving net-zero greenhouse gas emissions by 2050.

GE Aerospace's commitment to innovation extends beyond HyTEC. The company is actively engaged in CFM International's RISE program, aiming for over 20% improved fuel efficiency and 20% fewer CO₂ emissions by the mid-2030s, leveraging cutting-edge open fan engine architecture and engine compact core work.

All GE Aerospace engines can operate on approved SAF blends. Furthermore, the company is dedicated to developing technologies compatible with alternative energy sources, including 100% SAF, with several successful tests on different aircraft engine models.

In another stride toward eco-friendly aviation, GE Aerospace collaborates with NASA on the Electrified Powertrain Flight Demonstration (EPFD) program. This venture targets ground and flight tests for a megawatt-class hybrid electric propulsion system, set to be conducted in collaboration with Boeing using modified aircraft and GE Aerospace’s CT7 engines.


GE Aerospace's active involvement in NASA's HyTEC Phase 2 program underscores its commitment to pioneering advancements in aviation technology. With a focus on fuel efficiency, emissions reduction, and exploring sustainable aviation fuels, GE Aerospace is steering the aviation industry towards a greener and more sustainable future.
