RT-Balancer Information

The Rotortuner Balancer (RT-Balancer) is a portable or semi-permanently installed Propeller Balance and Vibration Analysis system for use on fixed wing propeller aircraft. Comprehensive balance solutions, unique advanced vibration analysis capabilities and a user-friendly interface make the RT-Balancer the engineer’s favourite propeller balancing equipment.

System Control
Overall control of the RT Balancer is through an ergonomically designed Hand-held System Controller (HHSC) with a touch sensitive membrane over a high-resolution back-lit LCD display. It is robust and easily readable making it ideally suited to the demands of the flight deck or cockpit environment, and is powered from the Data Collection Unit. All data and solutions may be viewed in flight and hard copies obtained from the integral printer. The unit currently supports two user-selectable languages; English, or German.

Data Input and Storage
Data from up to 8 accelerometers and 4 tachometer channels are integrated in the Data Collection Unit to provide data viewable as polar balance plots and frequency domain vibration signatures. All data is stored to a removable PCMCIA Card which is used for data transfer and subsequent detailed off-line analysis in the RT Vision Ground Support Station.

Data Analysis
The capabilities of the RT Balancer are determined by the Firmware currently installed, a full description of which may be found in the Firmware Data Sheet. In general the system will collect balance data from up to 8 different flight conditions and supply balance solutions according to the operators requirements, a range of vibration signatures up to 1000 Hz and 6400 lines resolution are available with at least one range covering the 1 x P and N x P frequencies. Other ‘windowed’ ranges may be configured to extract and highlight frequencies of special interest for specific aircraft diagnostic requirements.

Firmware Upgrade Options.
The system is designed so that future improvements and upgrades to the overall systems functionality, as well as refinements to aircraft information, may be incorporated through the use of Firmware Upgrade Cards or Aircraft Data Cards supplied on PCMCIA cards.
