Abstract
This disclosure describes a tension torsion strap for part of rotor head of a rotary wing aircraft. The tension torsion strap includes, in a direction of a longitudinal axis, a first peripheral area with a connection eye, a central section, and a second peripheral area with a connection eye. The tension torsion strap may be of one-piece made of a multiplicity of joined layers. Improved production and installation is of the tension torsion strap may be achieved by that disclosed in this disclosure, resulting in, among other advantages, more simplified maintenance because the tension torsion strap has an overall asymmetric shape relatively to a transverse axis due to two unequally shaped peripheral areas which cannot be brought into alignment when folding around the transverse axis.
