FasTrak
"No Hands" Helicopter Blade Tracking
The FasTrak day and night optical Blade Tracker as part of a 8500C or CHAMP™ system, provides blade track and lead/lag data automatically, without operator interpretation. The FASTRAK is mounted on the fuselage, oriented upward toward the underside of the rotating blades. It views each blade from each rotor through a ten degree window and operates on the principle that a high-flying blade will remain in the field of view longer than a low flying blade. Installation and operation with Chadwick systems are straightforward, using aircraft specific brackets and software.
