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.

Devices and methods of applying one or more testing forces to a rotor blade

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.

Joint assembly and method of forming thereof

Systems and methods for blade attachment are proved. The systems and methods include an aircraft system having a rotor hub including a blade connector and a composite blade including a lug fitting assembly. The lug fitting assembly includes a fitting core including a lug fitting aperture, a lug bushing coupled within the lug fitting aperture, and an outer fitting substantially surrounding the fitting core.

Systems and methods for blade attachment

A method for reducing bearing stress in a composite structure is disclosed. A composite structure comprises at least one coupling hole for coupling to the composite structure, and at least one bushing structure is coupled to the at least one coupling hole. A metal bushing retainer structure is coupled to the at least one bushing structure and the composite structure.
