GE Aerospace has successfully completed more than 3,000 endurance test cycles on advanced high-pressure turbine (HPT) airfoil technologies. The tests mark an important step toward developing a more compact and efficient jet engine core for future aircraft.
The HPT blade and nozzle tests showed better durability and improved fuel efficiency compared to current turbine designs. The test campaign simulated high-thrust phases like takeoff and climb to evaluate how the components hold up under real-world flight conditions.
Earlier testing efforts focused on verifying the thermal, mechanical, and system performance of the HPT hardware.
These developments are part of GE Aerospace’s work on a next-generation engine core—including the high-pressure compressor, HPT, and combustor—for a core demonstrator planned later this decade under the CFM RISE (Revolutionary Innovation for Sustainable Engines) program.
“With endurance tests conducted on new high-pressure turbine blade cooling technologies, it shows the CFM RISE program’s early focus on durability and reliability,” said Arjan Hegeman, vice president of future of flight engineering at GE Aerospace. “This is the earliest in new technology development that we’ve done durability tests, incorporating the experience of our commercial aircraft engines flying today.”
