Abstract：Based on the diffusion characteristics of water body and the requirement of engineering test, a measuring method of quantitative ground adhesion characteristics of fire extinguishing aircraft was designed. This method mainly includes three aspects: test equipment for ground data acquisition, matrix layout and accuracy evaluation. Considering the limitation of engineering test cost, the CFD simulation results of aircraft water delivery were presented. The paper cup ground array method was used to collect the falling water quality, and the mathematical methods such as numerical simulation and linear interpolation were synthesized. To evaluate the accuracy of water delivery for large amphibious aircraft, an experimental matrix scheme and a specific method were presented. The validity of the measurement method was verified by comparing the results of the test data drawn with foreign specific models.
