Description
technical field [0001] The invention belongs to the technical field of helicopter fatigue tests, and relates to a fatigue test loading device for a main lifter arm joint of an unmanned helicopter. Background technique [0002] The landing gear is an important part of the helicopter structure. The landing gear is the landing device of the helicopter, and it can absorb the landing process during the landing process of the helicopter, and can reduce the impact on the helicopter during the landing process. The main rocker joint is connected to the main landing gear of the helicopter and is fixed on the front fuselage. Its fatigue performance plays a vital role. In order to explore the fatigue performance of the main rocker joint of the unmanned helicopter, the unmanned helicopter main Rocker joint fatigue test loading device. Contents of the invention [0003] In view of the above-mentioned situation in the prior art, the present invention provides a loading device for fatigu...
