- Project Description
- The Rotary Dynamics Laboratory at NASA Glenn Research Center has acquired data on simulated engine disks for the purpose of developing crack detection schemes. They have taken data on a baseline disk and on a disk that has a fairly large crack introduced on it. The data consists of blade tip clearance measurements acquired at several speeds for a g...Moreiven duration. The intent is to see if one can detect the change in the center of mass of the disk due to the crack.
How Data Was Acquired: The data presented is from a physical simulator that simulated engine disks.
Sample Rates and Parameter Description: All parameters are sampled once per revolution measuring 32 blade to edge clearances on each revolution. Data is recorded for approximately 3 minutes for each run. The parameters are the revolution measurement, the clock time, the measured RPM, the maximum, average, and minimum gap across all gap sensors, and the measured gap for blade 0 to blade 31.
Anomalies/Faults: Faults include medium and large cracks on the disk....Less
