Description
technical field [0001] The invention belongs to the technical field of helicopter fatigue testing, and relates to a loading device for fatigue testing of a main rocker 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 has the ability to absorb the landing process during the landing process of the helicopter, which can reduce the impact on the helicopter during the landing process. The main rocker arm joint is connected to the main landing gear of the helicopter and fixed on the front fuselage. Its fatigue performance plays a vital role. In order to explore the fatigue performance of the main lifter joint of the unmanned helicopter, the main Rocker arm joint fatigue test loading device. SUMMARY OF THE INVENTION [0003] In view of the above situation in the prior art, the present invention provides an unmanned helicopter main ...
