Rotor centrifugal force retention device

A rotor assembly for use in an aircraft, the assembly comprising:

• a plurality of rotor blades;
• a tension-torsion strap for each blade, each tension-torsion strap including a radially inner end and a radially outer end;
• a blade retention device with a body having a plurality of protrusions that extend outward from a central portion of the body, each protrusion defining an elongated cavity sized for receiving the radially inner end of one of the tension-torsion straps, the radially inner end of the associated tension-torsion strap being carried within the cavity;
• wherein each cavity is oriented such that, when the radially inner end of the tension-torsion strap is received therein, a central plane of the tension-torsion strap is inclined relative to a blade plane of rotation defined by the plurality of blades;
• and
• wherein a fastener extends through each protrusion, cavity, and inner end for retaining the respective tension-torsion strap in place within the respective cavity.
