Proven Condition Monitoring Solutions

RT-TipTrak Information

RT-TipTrak has been developed as an aircraft installed device for measuring helicopter rotor blade height and lead lag either as an integral part of on-board HUMS systems or Rotortuner Track and Balance Systems.

The RT-TipTrak system uses ’Line Scan‘ camera technology allowing track measurement to be made at the blade tip, regarded in the helicopter industry as the optimum point of measurement.

Housed in a lightweight alloy casting and containing no moving parts, the RT-TipTrak has been designed as a high reliability system to meet the EMC and Environmental requirements of DO-160E.

The option of internal or external mounting offers maximum installation flexibility, the RT-TipTrak is provided with internal heating to prevent misting and ice accretion. The RT-TipTrak is fully compatible with all systems adopting the RITA data transfer protocols. Available as either a ‘day-only‘ system or with an optional removable ‘night mode‘ illuminator the RT-TipTrak has the ability to provide 24hour blade tracking capability.
The RT-TipTrak contains internal 1/rev conditioning allowing direct interface to an unconditioned 1/rev measurement sensor, negating the need for any additional signal conditioning units. Advanced blade recognition technology with 14 bit resolution eliminates the need for supplementary blade contrast enhancements such as the continual painting of rotor blades.
