Rotortuner RT-TipTrak
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.
Description
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 a 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.
