Abstract:
1. A tension-torque-transmission element for a rotor blade of a rotary wing aircraft, wherein a centrifugal force acts on the tension-torque-transmission element in use along a longitudinal direction, the tension-torque transmission element comprising: a connecting section on each of a blade side of the tension-torque-transmission element and a rotary axis side opposite the blade side; a connecting eye on each connecting section; and a torque-transmission section that connects the connecting sections, wherein the tension-torque-transmission element being designed in a fiber-reinforced composite design comprising several layers of a textile fabric, the several layers being interconnected at the connecting sections; the several layers of a textile fabric comprising: wherein in the region of the torque-transmission section, the tension-torque-transmission element forms height slots along the longitudinal direction between two unidirectional fiber bundles, each height slot being arranged as an air gap providing free space from one lateral surface of the separate lamellae to the lateral surface of the other separate lamellae.
