Abstract: IMPROVED CROSS BEAN ROTOR 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.

Abstract: ELASTOMERIC HELICOPTER ROTOR LOAD REACTION SYSTEM A helicopter rotor having one or more blades mounted for rotation with the rotor hub and each supported therefrom by an elastomeric bearing, and having a lead-lag damper connected to the blade and the hub and extending substantially parallel to the blade axis, and including the improvement of apparatus for preventing tension loading of the elastomeric bearing as the blade moves radially inwardly as a result of rotor braking.

Abstract: IMPROVED HELICOPTER ROTOR LEAD LAG DAMPER A helicopter rotor lead-lag hydraulic fluid damper has an internal anti-torque shaft preventing rotary motion of the dynamic fluid retaining seal. An independent fluid reservoir under centrifugal force supplies lubrication to the low-pressure side of the seal. At rest, the fluid returns to the lower reservoir chamber by gravity.

Abstract: This invention relates to a helicopter which has a rotor retractable from an elevated position to a retracted position. A first shaft projects from the helicopter fuselage and is supported therefrom for rotation about an axis of rotation. A second shaft projects from the first shaft and is connected to be drivingly rotated by the first shaft about the axis of rotation. The helicopter also includes a main lift rotor including a hub and blades, and the rotor is movable between the elevated position and a retracted position wherein the rotor hub envelops the first shaft for connection thereto. The invention also relates to a method for retracting the helicopter rotor from the second shaft to the first shaft.

Abstract: The fiber reinforced braided composite main helicopter rotor hub retention plate has a fiber orientation that withstands forces both in the plane of the retention plate and normal to the plane. The retention plate comprises a fiber reinforced resin braided tubular ring (3) having substantially circumferential fibers interwoven with angled fibers disposed about a central core. Arms (24) extend inward from the braided ring (9) for attachment to a driveshaft.

Abstract: ELASTOMERIC HIGH TORQUE CONSTANT VELOCITY JOINT A nearly spherical laminated elastomeric bearing has a non-circular latitudinal cross-section to accommodate high torque loads in elastomer bending rather than in shear. The nearly spherical profile of the bearing accommodates tilt primarily in shear. Both inwardly and outwardly extending lobes, or splines, are disclosed. The nearly spherical, lobed bearing is useful for a constant velocity joint.
