  • Variable hub-to-hub phasing rotor system
    Patent number: 10549849
    Abstract: An aircraft includes a first rotor assembly, a second rotor assembly, and a rotor phase angle control system. The system includes a phase adjustor operably associated with the first rotor assembly and the second rotor assembly. The method includes sensing vibrations exerted on the aircraft and offsetting a phase angle of the first rotor assembly and the second rotor assembly to minimize the vibrations.
    Type: Grant

  • Composite and metal hybrid gear
    Patent number: 10371243
    Abstract: According to one embodiment, a gear includes a steel portion that is oriented on a center axis. The steel portion includes a hub, a cylindrical rim, a web, and a plurality of engagement features. The hub is centered about the center axis. The rim has an exterior surface and an interior surface that surrounds the hub and is centered about the center axis. The web extends from an exterior surface of the hub to the interior surface of the rim. The engagement features are on the exterior surface of the cylindrical rim. The gear also includes a first composite piece adjacent to a first side of the web, the first composite piece extending from the hub to the interior surface of the rim, wherein the first composite piece does not extend past the hub towards the center axis.

  • Hybrid fluid elastomeric damper
    Patent number: 9334920
    Abstract: A damper includes a housing that forms a fluidly sealed cavity for receiving a fluid therein. The fluid is configured to change fluid properties as electrical energy is induced. An electrical subsystem provides electrical energy to the fluid, which is monitored with a control subsystem. The method includes inducing the fluid with electrical energy to change the dampening effects of the damper in real time.
