Airplane auxiliary power unit case study Spotbot Cellular GL
Industry: Aviation
Application: Auxiliary Power Unit
Challenge: An airline’s airplanes were being damaged in-flight, but no one knew why. The auxiliary power unit (APU), which is an
additional power source for the plane’s ignition, was destroyed sometime between every take-off and touch-down,
but the cause and timing of the impact was unknown. The APU’s design spec stated it could withstand a 9G impact
and the airline was concerned the design of the APU enclosure was defective.
Solution: The airline solved the mystery using a The ShockLog® Cellular GL impact monitor. They set the unacceptable
threshold level to 9G’s of impact, and mounted it to the APU’s enclosure on their plane before it took off.
The instant the plane landed, their questions were answered when a red dot appeared on the map in their
SpotSee Cloud. The airline company was easily able to pinpoint the exact time, location and magnitude
of the damage. It was determined that a 13G impact commonly occurred in the z-axis (under the aircraft)
upon landing, which was 4G’s beyond the specified impact threshold of the APU’s enclosure. This discovery
enabled the airline to write a more robust product specification and create an improved mounting solution
for their APU’s.
ShockLog® Cellular GL Overview
Real-Time Impact Monitoring and Tracking Solution
The ShockLog® Cellular GL Impact Recording and Tracking System combines an advanced shock and vibration data logger (the ShockLog 298) with real-time tracking. When a programmed impact level is exceeded, a detailed event curve will be recorded, and the ShockLog Cellular GL module will send a real-time alert letting you know when and where a potentially damaging impact has occurred during the journey. This allows you to act before the shipment is received or plan repairs before final installation of the asset in the field.
