Tackling the trillion-dollar problem of corrosion and aircraft durability in harsh conditions.

Learn how a combined CFD and corrosion tool kit analysis can help achieve more robust designs.

The NACE 2016 IMPACT study estimates the global cost of corrosion to be $2.5 trillion. It is estimated that savings of 15%-35% of this cost could be realized by implementing corrosion control and better design practices. 

From air fleet teardown inspections it has been found that more than 80% of aircraft structural failures are initiated from corrosion pits, many of which result from unintended galvanic interactions between a spectrum of materials ranging from modern light alloys, traditional, sacrificial surface coatings, and carbon fiber composites. The estimated annual cost of corrosion for the Naval and Marine Corps is $3.6B (LMI 2014). 

An important military impact of corrosion is asset availability (or lack of), as production scales-up for new assets such as F-35 Joint Strike Fighter, it has been necessary to lengthen the flight life of current fleets such as F/A-18s from 6,000 hours to 10,000 hours. (USNI News, April 2019).

In this webinar, you will learn how a combined CFD and Corrosion Simulation Tool kit analysis can help you achieve more robust designs through materials selection. We demonstrate how early design analysis can help engineering make better decisions mitigating potentially costly corrosion problems before they happen.

This session covers:

• Impact of the digital twin on durability in the next generation aircraft program 
• Validation of galvanic corrosion methods 
• Methods for identifying galvanic corrosion problems in design process 
• Evaluating proposed design alternatives through simulation 
• Troubleshooting identified corrosion issues
