Abstract
The invention relates to a rotor, specially for a gyroplane. The rotor comprises elongated connecting members respectively inserted between the rotor hub and the rotor blades. Each connecting member comprises a bundle of fibres having a high mechanical strength and agglomerated by a vulcanized elastomer at least in the mid part of the fibre bundle. A rigid tubular sleeve extends in a spaced and surrounding relationship to each elongated connecting member. Each tubular sleeve has an outer end connected to the root part of the respective blade and an inner end with a lateral lug articulated to the blade pitch control lever. An annular elastomer member is inserted in the annular space between the inner end of each tubular sleeve and the corresponding end of the respective connecting member.
