Travis Harper and his colleagues are developing the technology that could ultimately lead to an engine that would use 20% less fuel and produce 20% fewer CO2 emissions than the most efficient jet engines today.

GE Aviation and Safran today launched a bold technology development program targeting more than 20 percent lower fuel consumption and CO2 emissions compared to today’s engines. The CFM RISE (Revolutionary Innovation for Sustainable Engines) program will demonstrate and mature a range of new, disruptive technologies for future engines that could enter service by the mid-2030s.
