    Abstract: A helicopter hub main retention plate is described made up of graphite and glass fiber reinforced epoxy resin. The graphite fiber reinforcement is in-plane isotropically laid continuous graphite fibers and the glass fiber reinforcement comprises segments of fiberglass continuously and circumferentially wound round the areas of retention. Such materials and configuration provide crack resistance, damage tolerance, and integrity inspectability to the retention plate.

    Abstract: A helicopter rotor having an even number of articulated blades wherein opposing blades are interconnected by a common spar passing across the rotor axis. Pitch change is introduced to the blade at the spar-blade attachment joint through a torque member connected at its outboard end to the blade joint and including a control horn at its inner end to receive pitch inputs. Drive for the rotor and support for each blade is provided by a spherical bearing directly connecting the torque member to the blade associated hub arm.
