Blade Diagnostics Corporation (BDC) software

An IBD’s risk of developing High Cycle Fatigue (HCF) problems can change dramatically over its lifetime. Blade Diagnostics provides the tools to monitor HCF health over the life of the part, so you can keep your fleet operating safely.

When it comes to vibration, no two IBDs are alike. Every IBD has a unique set of properties that causes it to vibrate differently than all other bladed disks, even those of the same design. One of BDC’s objectives is to identify which parts are genetically predisposed to fail from HCF, and then alter them to lower HCF risk.

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.
