The innovations that make BLR products so effective are deceiving in their simplicity – and the FastFin® Tail Rotor Enhancement and Stability System is a case in point. FastFin modifies the tailboom with Dual Tailboom Strakes and a re-shaped vertical fin. This optimizes airflow in a way that delivers big improvements in handling, safety and lifting. FastFin provides a dramatic increase in tail rotor efficiency by reusing energy from the main rotor wash to aerodynamically enhance the anti-torque available for hover operations. Additional efficiencies are gained by reshaping the vertical fin to reduce blockage area and minimize hover challenges associated with critical wind azimuth.
When BLR products get new STC Approvals, be among the first to know.
