Blade attachment for a bearingless rotor of a helicopter

A blade attachment for a bearingless rotor, particularly a main rotor, of a helicopter, comprising:

• an airfoil blade having a tip end and a root end forming opposite ends thereof and having a pitch axis from said tip end to said root end;
• a flexbeam including a flexbeam body and a flexbeam head at an end of said flexbeam body, said flexbeam body being flexible;
• a control cuff enclosing and extending along at least a predominant portion of said flexbeam;
• a separable junction arrangement between said flexbeam head, said control cuff and said root end of said airfoil blade, wherein said junction arrangement is mechanical between said flexbeam head, said control cuff and said root end of said airfoil blade with removable fasteners respectively removably connecting said root end of said airfoil blade and said control cuff with said flexbeam head, said removable fasteners comprising a main bolt and a supporting bolt both arranged lying perpendicular to the lead-lag pivoting plane of the airfoil blade and being asymmetric with regard to said pitch axis of said airfoil blade.
