    摘要: The invention provides a balance bar twin blade hub. A beam is formed of a tube made from a composite material of evolutive form whose section is cylindrical at its end on the blade side and progressively elliptical as far as its central connection part. It is connected to a support stirrup 2 conical stratified stops 4 forming balance bar bearings identical to the conical stratified stops forming the centrifugal force take up and angle of attack bearings providing the connection between the blade 16 and the beam.

    摘要: The flexible girder made of composite materials and with high energy absorption is in the form of an elongate box of laminated structure comprising two rigid flanges (6,7) connected by two webs (9) which have aligned apertures (13). A deformable energy-absorbing block (14') is arranged between the two flanges (6,7) at the apertures and comprises a block of an elastomeric material (15). The block (14') absorbs the buckling deformation energy of the flange (6) which is subjected to compressive stress during flexion of the girder, by resting on the other flange (7) which is subjected to tensile stress. The block (14') controls the buckling of the flange (6) and only gives back part of the energy absorbed. Application to the equipment in particular of skid landing gear for helicopters and tail skids for aircraft.

    摘要: The invention concerns laminated stops of curved shapes, particularly for helicopter rotors. The stop has an inner fitting and an outer fitting connected by cupped elements of a resistant and rigid material alternating with layers of flexible material. The layers of flexible material increase in thickness from their centers outwardly, and the mean thickness of the flexible layers increase from the inner fitting to the outer fitting.
