  • Devices and methods of applying one or more testing forces to a rotor blade
    Patent number: 10732072
    Abstract: A device for testing a rotor blade of an aircraft. The device is configured to receive and secure a shaft of the rotor blade. Once secured, the device is configured to allow for inputting combined loads and bending moments into the rotor blade to simulate the rotor blade behavior in flight. A testing assembly is also disclosed that includes the device and the rotor blade and methods of use that provide for testing the rotor blade.
    Type: Grant
    Filed: February 1, 2018
    Date of Patent: August 4, 2020
    Assignee: THE BOEING COMPANY

  • Joint assembly and method of forming thereof
    Patent number: 10167075
    Abstract: A joint assembly includes a first component formed from a first material and a second component including a portion that extends at least partially into the first component and that has an uneven outer profile. The first material is configured to form the first component into a shape that is substantially complementary to a shape of the portion to facilitate restricting movement of the second component in an axial direction.
