The work studies the design method of cushioning packaging for airborne carrying equipment in order to improve the reliability of carrying equipment. The value of the opening and landing shock load was obtained from theoretical calculation to judge the input of the buffer packaging design. The design scheme of cushioning package was optimized through the reasonable selection of cushioning packaging material and the accurate design of cushion thickness. The feasibility and validity of the design method was verified by the ground test. By optimizing the design, after cushioning packaging, the landing impact of a certain type of airborne equipment dropped from 48.7g to 17.7g, which could ensure the good and normal use of airborne landing equipment. The difference between maximum dynamic load value and actual measurement value of the maximum dynamic load was relatively small. In conclusion, the calculation method used in this project can be used in design of cushioning packaging for airborne equipment. The cushioning packaging design not only can protect equipment, but also has important practical significance for weight losing.
