  • Prop rotor hub
    Patent number: 6296444
    Abstract: A prop rotor hub includes a constant velocity joint in the same plane as a prop blade yoke. Torque is transmitted from a shaft to the blades through the CV joint, hub plates attached to the CV joint, and the yoke, which is attached to the hub plates. Providing all elements in a substantially planar arrangement results in a hub assembly which has significantly less height than a traditional design. The hub itself is in-plane with the yoke, resulting in a more efficient torque transmission from the mast to the rotor.

  • Technique for making fiber composite object
    Patent number: 6263936
    Abstract: A complex object, such as a spar for a tilt-rotor aircraft rotor blade, is manufactured from fiber composite materials. Unbroken fiber strips are laid along the length of the spar to maximize the number of full length fibers used in the spar. Cross-sectional areas along the length of the spar can change in both shape and area. The fibers are laid to accommodate and form these variable shapes. The locations for the fibers are determined by defining locations for the strips for each cross-section, then connecting corresponding points together to specify where the strips are to be laid down.
