发明名称 Aerodynamic blade attachment for a bearingless rotor of a helicopter
摘要 The invention relates to an aerodynamic blade attachment (1) for a bearingless rotor, particularly a main rotor, of a helicopter, comprising: an airfoil blade (2) 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 (3); a control cuff (4, 22) enclosing and extending along at least a predominant portion of said flexbeam (3) and a separable junction arrangement between said flexbeam (3), said control cuff (4) and said root end of said airfoil blade (2), wherein said junction arrangement is mechanical between said flexbeam (3), said control cuff (4) and said root end of said airfoil blade (2) with removable fasteners (5, 6) respectively removable connecting said root end of said airfoil blade (2) and said control cuff (4) with said flexbeam (3). Said junction arrangement comprises fairing means (10, 27, 28, 31, 32 and 39) encompassing the removable fasteners (5, 6) and said flexbeam (3).
