Full-scale LEAP fan blade-out rig test yields outstanding results

Testing of CFM International’s advanced 3-D Woven Resin Transfer Molding (3-DW RTM) fan is proceeding on schedule and the company is achieving outstanding results . In May, CFM completed a full-scale fan blade out rig test, simulating certification requirements for the proprietary 3-DW RTM technology.  The company has also completed extensive full-scale component tests, including bird ingestion testing with the same very positive results. Endurance testing of 3-DW RTM fan is also proceeding on schedule, with 3,500 of the planned 5,000 cycles completed.  The demanding test was designed to evaluate fan behavior within a real thermal and vibratory environment.  The results have been outstanding, meeting or exceeding all pre-test predictions.
