摘要： This invention relates to a rotorcraft rotor head which includes an even number of blades arranged in groups of two blades (2) which are diametrically opposed to each other, and linked to each other by a connection system without any link with the rotor hub. Each blade (2) is articulated in flapping and in pitch on the hub body (1) by a sleeve (3) which is arranged between the root of the blade (2) and the hub body (1). The sleeve (3) bears against the periphery of the hub body (1) by a laminated spherical stop (5) and includes an introduction member for controlling the pitch of the blade (2). Each system for connecting two diametrically opposed blades (2) is comprised of two tie rods (4) which link the two diametrically opposed sleeves (3) of the blades (2). The two tie rods (4) are arranged parallel to the plane of the rotor on either side of the longitudinal axis which is common to the two diametrically opposed blades ( 2). The two tie rods (4) are parallel and substantially spaced apart with respect to the common longitudinal axis. The member which fastens the two tie rod (4) to each sleeve (3) is arranged on the outside of the laminated spherical stop (5) of the sleeve (3) with respect to the rotor axis such that the length of the two tie rods (4) is significantly greater than the distance between the centers of the two diametrically opposed laminated spherical stops (5).

摘要： Landing gear for aerodynes and especially helicopters comprising two lateral members (2) for contact with the ground being linked to the fuselage of the aerodyne by at least two crosspieces (3, 4). These crosspieces (3, 4) are produced as a bundle (7) of unidirectional synthetic fibers sheathed by a skin (8) of tissues of fibers which are crossed with respect to the unidirectional fibers of the bundle (7). The extremities (9) of the crosspieces are embedded in the lateral members (2) for contact with the ground. The structural links between the crosspieces (3, 4) and the fuselage of the aerodyne (H) allow the pivoting of the crosspieces (3, 4) about transverse axes of the aerodyne (H).

摘要： The rotor comprises a hub 2 rotated with a mast 1 about an axis of the rotor ZZ, and each blade 3 is connected to the hub 2 by a member 5 on which the blade 3 is mounted so that the blade 3 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 1. In automatic folding, the blade 3 is held in a fitting 6 pivoting on the member 5 about the axis of folding BB, whereas in manual folding, the blade 3 is held on the member 5 by two pins 8, one of which is removable to allow the blade to be folded about the other pin 8, the longitudinal axis of which is the axis of folding BB inclined in the radial plane.
