Meggitt propeller monitoring chosen by ATR

Meggitt has been awarded a contract from ATR for the OEM to use Meggitt’s proprietary onboard propeller-balancing system, which monitors the vibration of propellers so they can be balanced correctly, reducing cabin noise and wear on both engine bearings and gearbox components.

The first units will be delivered in 2017. Also, the onboard propeller-balancing system can be retrofitted to the existing fleet of 1,500 aircraft.

“Introducing propeller vibration monitoring is part of our incremental development policy. It will contribute to enhance passenger experience, increase reliability and reduce ATR aircraft maintenance costs,” explained David Brigante, ATR’s senior vice-president, procurement. “The system is designed to interface with our most recent propellers[on the] ATR -600s, and the legacy configuration in retrofit.”

Annette Hobhouse, president, Meggitt Sensing Systems, added, “Before our new lightweight distributed system, there were limits to what could be monitored on an aircraft because of technical and commercial barriers. Now, virtually any aircraft system can be monitored to improve performance and plan economic, condition-based maintenance.”
