Proven Condition Monitoring Solutions

WhirlTrak Information

The Helitune WhirlTrak™ system is a totally integrated solution for the measurement of rotor blade track upon whirl tower test stands. The system comprises Helitune’s RT-TipTrak line scan tracking camera, a 1/Rev indexing sensor and a base station PC system running Helitune’s WhirlTrak control software and results management database.

The system is able to be integrated with discrete I/O logic from the rotor tower control system for precise rotor tower test condition identification. In addition, the system provides a real-time digital data stream output which can be integrated with additional third party control systems. Interfaces are provided for the integration of an optional CCTV camera and wind measurement system to supplement the WhirlTrak data if required.

The Helitune WhirlTrak™ controller software, which runs on the base station PC system, is responsible for all system control, measurement and data management functions. The system provides a continuous real-time interface, allowing both live and averaged track output readings. A single system installation is able to support multiple rotor blade types and test profiles, which are configured independently against the requirements of each blade type. The system automatically configures the Helitune RT-TipTrak measurement camera, based upon the selected blade type and measurement procedure, providing for reliable and error-proof system operation. The Helitune WhirlTrak controller software supports access control for administrator and operator levels, allowing system configuration parameters to be available to the system administrator only.


All measurement results are stored into a Microsoft® SQL results database, which allows for reliable data archiving, data retrieval and output reporting. The user interface has full integration with Microsoft Excel for results export, allowing operators the flexibility to generate unique output report template profiles.
