Airwolf develops Tension-Torsion Straps

March 08, 2011
March 8, 2011 – Airwolf Aerospace has developed a new Tension-Torsion (TT) strap for Bell 206 Jet Ranger and 206L Long Ranger helicopters, civilian and military. The straps will be on display at HAI Heli-Expo, 2011 (Booth #3561). Airwolf manufactures the straps under an FAA Parts Manufacturer Approval (PMA).

Airwolf’s TT straps anchor each rotor blade to the mast while accommodating the multi-directional forces inherent in rotorcraft flight. The straps are manufactured from a specially designed, proprietary process to far better accommodate the torsion and tension requirements of the rotor hub, smoothly and safely.

Airwolf Aerospace Senior Engineer, John Montana, said, “The development of Airwolf’s new Torsion-Tension straps is the result of more than seven years of R&D. We have created a product that is technically superior and significantly less expensive than those from the factory.’’

Airwolf will launch its newest certified product at Heli-Expo 2011 to answer any questions regarding its price, its use and installation, and to show potential consumers the benefits that this product offers to Bell 206 owners. TT straps must be replaced at 1200 hours or two years, according to Bell Helicopter.

“For years the only ‘option’ was no option at all. Now, there’s a much more affordable and FAA-approved alternative,’’ Montana added.

The straps can be installed in the field by a licensed engineer, are priced significantly lower than those from the factory. They are approved for all Jet Rangers, Long Rangers, and military OH 58s.

Airwolf Aerospace LLC. is the world’s leading manufacturer of helicopter rotor blade anti-erosion tape specifically designed to eliminate the delamination of Robinson R22 & R44 main rotor blades.
