1526815 Helicopter rotor blade attachments MESSERSCHMITT - BOLKOW - BLOHM GmbH 20 Nov 1975 [26 Nov 1974] 47857/75 Heading B7W A root attachment fitting for a helicopter rotor blade comprises a hub attachment pin 3 encased by a bush 2 around which is formed a looped eye 4 of fibre-reinforced plastics. To ensure more uniform distribution of forces between the bush 2 and the eye 4 a further loop 5 constructed in the same manner as the eye 4 is formed in the loop cavity with further fillers 7 and 8 of plastics with or without fibre inserts inserted in the remaining cavities. The construction may provide for the fibres in the loop 5 to be interwoven between the fibres of the eye 4.
