CFM International has initiated critical dust ingestion testing for its next-generation high-pressure turbine (HPT) airfoils, marking the earliest this type of durability assessment has ever been performed in an engine program. This testing is a core component of the CFM RISE technology demonstration program, which aims to develop advanced, sustainable propulsion technologies. The tests utilize a proprietary mix of sand and particles developed by GE Aerospace, a parent company of CFM. A specialized test rig subjects the engine components to thousands of simulated flight cycles, including takeoff, climb, cruise, and landing, to replicate the severe operating environments encountered by global airlines.
The primary goal is to optimize the durability and efficiency of future engine products. This early and rigorous testing incorporates operational lessons from the current flying fleet to ensure the new technologies are robust. The RISE program is developing a compact engine core, which includes the high-pressure compressor, HPT, and combustor. This core has already passed its Conceptual Design Review. Earlier in 2025, the program completed more than 3,000 endurance cycles on advanced HPT airfoils, validating their thermal, mechanical, and system performance.
Unveiled in 2021, the expansive RISE program has completed over 350 tests to date. It is maturing a suite of revolutionary technologies, including open fan architecture, hybrid electric systems, and a high-speed turbine and compressor. A key target for the program is achieving more than 20% improved fuel burn compared to today’s best commercial engines. Technologies from the RISE program are progressing toward ground and flight tests later this decade, with work actively underway on aircraft and engine integration.
