ABSTRACT:
In a rotor for a rotary wing aircraft, an integral central headpiece supps the rotor blades. The headpiece consists of two plates interconnected by a centrally arranged distance member. Each plate has a similar star-shape with at least four angularly spaced point-like arms. Each plate is formed of a number of superposed layers with each layer containing continuous loops extending in the direction of the point-like arms. At least one loop extends from one point-like arm into another diametrically opposite point-like arm. Others of the loops, located in the other point-like arms, extend radially outwardly from the loop extending through the two point-like arms. The headpiece consisting of the plates and distance member, is a unitary or integral structure.
