CINCINNATI – CFM International, the joint venture between GE Aerospace (NYSE:GE) and Safran Aircraft Engines, has commenced dust ingestion testing on next-generation high-pressure turbine (HPT) airfoils, marking the earliest such testing in the development of its RISE technology demonstrator.
Designed to simulate real-world operating conditions, the testing campaign aims to optimise durability and ensure engine technologies meet the rigorous demands of commercial operations. The proprietary test protocol uses a mix of sand and other particles, injected via a specialised rig over thousands of cycles to replicate takeoff, climb, cruise, and landing conditions.
Arjan Hegeman, vice president for the future of flight at GE Aerospace, said: “With the RISE technology demonstration program, we’re pursuing durability and efficiency improvements with equal focus. This incorporates lessons from the flying fleet today to inform our future engine products by testing early and often.”
Core Development Underway
CFM is developing a compact engine core encompassing the high-pressure compressor, HPT, and combustor technologies for a demonstrator planned later this decade. The core has already completed its Conceptual Design Review. Earlier in 2025, more than 3,000 endurance cycles of advanced HPT airfoils were successfully completed, building on prior testing of HPT blades and nozzles that validated thermal, mechanical, and system performance.
About the RISE Program
Launched in 2021, the CFM RISE (Revolutionary Innovation for Sustainable Engines) program is one of the most comprehensive aviation technology demonstrators to date. Over 350 tests have been conducted, covering advanced architectures including Open Fan, compact core, high-speed turbine and compressor, and hybrid-electric systems.
RISE targets more than a 20% improvement in fuel burn compared with current commercial engines while maintaining a focus on safety, durability, and efficiency. Technologies from the program are maturing toward ground and flight tests this decade, with ongoing aircraft and engine integration work in collaboration with industry partners.
In September, GE Aerospace appointed Craig Higgins as Chief Mechanic and Architect for Open Fan technology, emphasising the producibility, durability, and maintainability of next-generation engine designs.
Note: RISE is a technology demonstration program and is not offered for commercial sale.
