Propeller Balance Monitoring Systems
The Ultra Electronics Controls PBMS system has been adopted on the following platforms:
- Bombardier Q200, Q300 and Q400
- Lockheed Martin P-3
Successfully trialed on the Lockheed Martin C-130
System Features:
- Accelerometers mounted on the engine gearbox communicate radial vibration data to the controller.
- This data and phase data are gathered periodically at the shaft rotation frequency (1P).
- Data is then transferred from the controller to the balancer terminal (laptop PC) at the operator’s convenience.
- The balancer terminal informs the operator of the optimum, minimum mass, rebalance solution
Benefits to the Operator:
- 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 < 1 hour
- No test flight required
