Bladed disks vibrate in complex, and often peculiar ways. Within a single IBD, some blades may vibrate strongly in an engine, while others barely at all. And two seemingly identical IBDs may vibrate so differently that one fails quickly from HCF while the other operates without issue for its entire lifespan.
BDC understands the intricacies of bladed disk vibration, and has developed software that accurately predicts the vibration levels of IBDs. BDC’s FMM Predictor is a patented algorithm that accurately simulates how a given IBD will vibrate in an engine based on its unique characteristics, or Vibratory DNA.
As a Core Technology, FMM Predictor is a key component of many BDC products and services.
