CFM advances LEAP engine health monitoring

Business

  • Leveraging machine-learning capability
  • Providing most accurate engine operation data modeling to date 

MRO Americas – CHICAGO, Illinois – 10 April 2024 – As the number of LEAP engine operators grows worldwide and the fleet approaches the 50 million flight hour milestone, CFM International has expanded its engine health monitoring capabilities with machine learning to provide operators with more accurate insights than ever before.

The system now being used for CFM LEAP-1A and LEAP-1B engines models data from multiple engine sensors at takeoff, climb, and cruise  via  probabilistic diagnostic and prognostic machine learning tools.  These tools then provide targeted alerts based on known engine operating signatures.  The operational models being generated are the most accurate  the company has seen to date and are resulting in earlier detection of potential issues. 

The system has been used extensively for more than a decade on CFM56 and other engines and, thus, benefits from the experience of a wide portfolio of products, a quality dataset, and deep domain expertise. The CFM LEAP engine is helping advance the state-of-the art in predictive maintenance.

“With the combination of this health monitoring system and the expertise of our global CFM fleet support team, we have achieved 60 percent earlier lead time in identifying preventative maintenance recommendations,  a 45 percent increase in detection rates, and cut the number of false alerts in half over the past decade,” said David Harper, Fleet Support Director for CFM parent company GE Aerospace. 

“These state-of-the-art analytics are providing LEAP operators with the data they need to make informed, insightful decisions about fleet management,” said Agathe Venard, Head of Fleet Data Engineering for CFM parent company Safran Aircraft Engines. “As a result, they gain a level of fleet stability they can rely on in their day-to-day operations.”
