GE Aerospace has announced revenue rose by 27% in Q2 2022 thanks to new additive manufactured (AM) fuel nozzle-enabled engine sales. The revenue boost is thanks to its sale of over 200 CFM International LEAP-1B engines to major clients Delta Air Lines and Qatar Airways. The engines feature AM fuel nozzles that are 15% more fuel efficient than CFM56 alternatives. As part of the July 2022 agreement, the engines will soon be fitted to the customers’ fleets of Boeing 737-10 aircraft, allowing them to be more sustainable and reduce fuel consumption.
