The Tension Torsion strap provides critical attachment and pitch movement of the Rotor Blade in an aerodynamically efficient package.  This is a highly effective solution particularly where space is at a premium.

What are Tension Torsion Straps?

The TT Strap is a flight-critical part that attaches the rotor blade to the rotor hub of a helicopter. These parts take the entire centrifugal force of the rotor blade while allowing pitch input, or feathering, of the blades, all in a compact package

LORD TT straps are designed for more than 20 different aircraft applications and has manufactured more than 500,000 straps. This experience, coupled with ongoing investment in manufacturing facilities and equipment, gives our customers confidence in the quality and reliability of our product.

Our customers also benefit from the fact that Parker Lord is the PMA holder, designer and manufacturer of the TT strap the corporation supplies.
