United States, Oct. 10 -- GE Aerospace joint venture CFM International has begun dust ingestion testing on next-generation high-pressure turbine (HPT) airfoils. The earliest CFM has conducted this type of testing, it simulates the real-world operating conditions of engine technologies in development to optimize for durability. Dust ingestion testing uses a proprietary mix of sand and other particles developed by GE Aerospace. A specialized test rig injects dust into the engine over thousands of cycles representing takeoff and climb, cruise and landing. The test campaign will replicate how the parts would withstand flight conditions in severe operating environments around the world, important for customer operations. Core testingCFM is devel...
