"No Hands" Helicopter Blade Tracking
The FasTrak™ day and night optical Blade Tracker as part of an
8500C or Enhanced Vibrex 2000 Plus 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.
