abstract

High cycle fatigue (HCF) is a widespread technical problem in aircraft gas turbines, and can lead to the premature failure of plumbing, pumps, accessory drives and airfoils. Roughly 35% of the problems associated with newer production engines are the direct result of HCF. This paper discusses three innovative technologies that can assist in the avoidance or elimination of high cycle fatigue failures in aircraft gas turbines. This work was performed under the sponsorship and direction of the Defense Advanced Research Projects Agency (DARPA) and the United States Air Force Research Laboratory.
