More innovation with Eurocopter s signature tail rotor



More innovation with Eurocopter s signature tail rotor


Eurocopter, March 08, 2011 - The Fenestron shrouded tail rotor, which was pioneered by Eurocopter and has been applied on five of its helicopter products, has been further improved and optimized for its newest application on the EC145 T2 that was unveiled this week at Heli-Expo 2011.

Overall advantages of the Fenestron include significantly higher safety levels on the ground, during landing/takeoff operations in confined areas, and in flight; enhanced anti-torque control efficiency; reduced power demand in forward flight; and lower sound and vibration levels.

For the EC145 T2, Eurocopter has sized the Fenestron at a diameter of 1.15 meters. Among its features is the use of 10 composite blades, each of which is mounted using integrated tension/torsion straps. This application of the integrated blade and strap design eliminates blade mount joints, removing the opportunity for corrosion build-up, and significantly improving maintenance with easy blade removal and reinstallation.

The EC145 T2’s Fenestron is driven by an all-new lightweight gearbox that has a high operating lifetime, and the helicopter’s tail rotor drive shaft utilizes state-of-the-art ceramic bearing supports with very good corrosion resistance and a longer lifetime. Another new feature is the EC145 T2 Fenestron’s installation on an all-composite tail boom, which has a damage-tolerant design and includes provisions for easy customizing – including the installation of antennas.
