  • Constant velocity joint with asymmetric opposed tracks
    Patent number: 12234864
    Abstract: A constant velocity joint assembly includes an outer joint member defining a first longitudinal axis and including a closed end, an open end, a first set of outer tracks extending at least partially between the closed end and the open end, and a second set of outer tracks extending at least partially between the closed end and the open end. The assembly also includes an inner joint member defining a second longitudinal axis coaxial with the first longitudinal axis and including a first set of inner tracks and a second set of inner tracks, the inner joint including an attachment feature to receive a driveshaft. A path followed by the center of a ball in the first set of tracks is constrained by an outer race track path and an inner race track path, the outer race track path being a piecewise continuous function.

  • Rotary beam variable stiffness wing spar
    Patent number: 6000660
    Abstract: A segmented rotatable beam provides a spar or rib in an aircraft wing. The rotatable beam has a variable stiffness dependent upon the radial orientation of the rotatable beam about a longitudinal axis of the beam. The segmented rotatable beam comprises a plurality of tubular segments that are pivotly interconnected by connecting beam links that are rotatably mounted in bearings disposed along the longitudinal axis of the beam.
