GE Highlights Sustainable Aviation Fuel in Testing 10 Different Engines

After completing testing on its tenth engine model running exclusively on Sustainable Aviation Fuel (SAF) since 2016, GE Aerospace achieved a significant milestone towards a more sustainable future of flight.

This confirms that the company and its joint ventures have one of the industry’s largest programmes for testing alternative fuels.

Additional engines include F414, GE9X, LEAP-1A, Passport, GEnx, HF120*, and CFM56 engines that were tested at the component, engine, or aircraft level using 100% SAF. The extensive battery of tests covers a variety of propulsion systems utilized in business and general aviation, military aviation, and domestic and international commercial aviation.

Numerous other variables were also assessed in these tests, including engine performance and the effect of 100% SAF on emissions and contrails. Approximately three-quarters of all commercial flights worldwide are powered by GE Aerospace and its joint ventures.

GE Aerospace is moving from engine system testing to engine component and sub-component level evaluations to aid in the qualification of new 100% SAFs. This includes assessing all parts affected and exposed to fuels, ranging from the fuel system of the engine to the combustor, which burns the fuel. Tests are being conducted on different types of SAF produced from different pathways to determine if there is any effect on engine operability, efficiency, durability, and emissions.

Additionally, GE Aerospace is an inaugural investor in the United Airlines Ventures Sustainable Flight Fund to help increase the supply of SAF.
