Abstract
The rotor comprises a hub,rotated with a mast,about an axis of the rotor ZZ, and each blade,is connected to the hub,by a member,on which the blade,is mounted so that the blade,can pivot about an axis of folding BB between a flight position and a folded-back position. The axis of folding BB is in a substantially radial plane passing through the axis of the rotor ZZ and is inclined with respect to this axis of the rotor ZZ so that it converges towards it, on the opposite side to the rotor mast,. In automatic folding, the blade,is held in a fitting,pivoting on the member,about the axis of folding BB, whereas in manual folding, the blade,is held on the member,by two pins,one of which is removable to allow the blade to be folded about the other pin,the longitudinal axis of which is the axis of folding BB inclined in the radial plane.
