  • Tip end joint arrangement for a rotor blade with reconfigurable attributes for structural and aerodynamic tuning
    Patent number: 12497166
    Abstract: A rotor blade configured to couple to a rotor assembly having an axis of rotation includes a blade radius R between the axis of rotation and an outboard end of the rotor blade when coupled to the rotor assembly. When an inboard end of the rotor blade is coupled to the rotor assembly at about x/R=0.10, between about 18 percent and about 22 percent of the total mass of the rotor blade is located between about x/R=0.88 and about x/R=0.93, x corresponding to a radial location of the rotor blade measured from the axis of rotation.
    Type: Grant
    Filed: February 3, 2025
    Date of Patent: December 16, 2025
    Assignee: LOCKHEED MARTIN CORPORATION

  • Tip end joint arrangement for a rotor blade with reconfigurable attributes for structural and aerodynamic tuning
    Patent number: 12214872
    Abstract: A rotor blade configured to be installed on a rotary-wing aircraft includes a main blade body including an inboard end configured to be coupled to a rotor blade hub and an outboard end. The rotor blade includes a blade tip removably coupled to the outboard end of the main blade body, the blade tip including an inner cavity. The rotor blade further includes a tip block including an inboard portion coupled to the outboard end of the main blade body and a cantilevered portion extending beyond the outboard end of the rotor blade and into the inner cavity of the blade tip.
