Propeller balance monitoring system (PBMS)

Our propeller balance monitoring system (PBMS) leverages our extensive experience in aircraft vibration control. Our system has been providing operators with propeller balancing solutions since 2000 and has been fitted to seven different aircraft types. The system utilizes normal service operation to determine the balance state of the propeller systems, and our dedicated ground terminal software can provide this status to maintainers, provide balance solutions and vibration predictions and allow the operator to maintain the system.

Core features

  • Reduces operating costs compared with carry-on systems

  • No dedicated ground runs are required

  • No dedicated flights are required

  • Data is gathered during normal service operation

  • No carry-on equipment required, all parts permanently installed

  • High reliability of components

  • No parts calibration required

Operator benefits

  • 56% reduction in overall vibration levels compared with the standard ‘carry-on’ method of propeller balancing

  • Balance data is gathered continuously during the normal flight envelope and is readily available

  • The time taken to balance a four-engine aircraft is less than 1 hour

  • No test flight or dedicated ground runs are required
