Abstract :
The fleet of Health and Usage Monitoring Systems (HUMS) equipped aircraft is growing rapidly. With the UH-60M having HUMS as original equipment, it is anticipated that there will be more than 1200 aircraft proving parametric and vibration data. Considering that each aircraft produced 20 MB of data per flight hour, 100 flight hours per month, a fleet of 1200 aircraft will generate 29 Terabytes of data. This paper explores a methodology for data compression to significantly reduce the storage requirements for this data. The effects of compression on event detection (parametric and vibration) is explored and bounds are error are given.
