Damage Tolerance for Gas Turbine Engines


The simultaneous demands for reliability and minimum weight for aircraft and propulsion systems offer some of the most challenging technical problems that structural and safety engineers can encounter. Although much information is available on fracture mechanics and aircraft damage tolerance, this course specifically relates to damage tolerance for gas turbine engines. The need to consider damage tolerance more broadly in new engine designs has just recently been written into FAR 33.70 and new EASA guidelines. With an increasing need for education, both in the U.S. and internationally, this seminar relates directly to the growing interest and priority the AIA, FAA, and engine OEM"s have placed on turbine engine damage tolerance.


This two-day seminar offers a broad survey of damage tolerance, one of the many principles behind one of the safest industries in the world. Although the basics of fracture mechanics will be covered, this is not an advanced fracture mechanics course. Attendees will be presented information on how experts in the propulsion community use the principles of prevent, quantify, and improve to keep air travel safe. The instructor will guide participants through notable historical events as well as experiences within a leading engine manufacturing company. The basics of fracture mechanics will be covered with a view towards practical application. Traditional deterministic and the newest probabilistic approaches will be introduced. Finally, attendees will be exposed to a broad range of improvements that have been made to address specific threats within the propulsion business.

What Will You Learn

By attending this seminar, you will be able to:

  • Evaluate the sensitivity of structures to different types of damage
  • Explain what it means for a design to be “damage tolerant”
  • Identify three pronged approach of prevent, quantify, and improve aimed at safety
  • Discuss basic principles of fracture mechanics
  • Identify steps involved in deterministic and probabilistic approaches

Is This Course For You
