A Simple & Effective Performance Solution

Operators worldwide are amazed that something so simple contributes so much to everyday operations.

The BLR Tailboom Strake Kit is the most cost effective, multi-functional, value added, modification ever developed for single rotor helicopters (with enclosed tailbooms). BLR Tailboom Strakes are the culmination of seven years of wind tunnel and flight test work by NASA/US Army researchers during the late 1980's. BLR's strake design has been optimized for: ease of installation, improvements to handling qualities, performance improvements for climb & cruise flight, an increase in overall yaw control safety margins, and all while providing operators reductions in direct operating costs. This technology is now available in kit form for installation on Bell Models:
204B, 205A-1, 205B (Huey II), 206B, 206L, 212, AB212, AB205, OH-58, 412, UH-1 and AH-1.

Benefits Include:
Improved Hover-Hold Tasks
Improved Yaw Control Margins
Improved High DA Capability
Reduced Cruise Torque
Reduced Tail Rotor Power Requirements
Reduced Operating Costs (fuel savings)
