摘要： The invention relates to a blade attachment (1, 20) for a bearingless main rotor of a helicopter with an airfoil blade (2), a flexbeam (3, 21) including a flexbeam body (16, 17) and a flexbeam head (13) at an end of said flexbeam body (16, 17). A control cuff (4, 22) encloses and extends along at least a predominant portion of said flexbeam (3, 21). A separable junction arrangement between said flexbeam head (13), said control cuff (4, 22) and said root end of said airfoil blade (2) is mechanical with removable fasteners. Said removable fasteners comprise a main bolt (7) and at least one supporting bolt (8)

摘要： The invention relates to an airfoil blade (2) of a bearingless rotor of a helicopter. Said airfoil blade (2) has a pitch axis from a tip end to a root end and said root end is provided with junction means for a separable junction arrangement of said airfoil blade (2) with a flexbeam head, and a control cuff (4, 22). Said junction arrangement is mechanical with removable fasteners respectively removable connecting said root end of said airfoil blade (2) to said control cuff (4, 22) and said flexbeam head (13). Said root end comprises at least two openings (7, 8) being asymmetric with regard to said pitch axis.
