| Abstract: |
| Currently, no snowfall test about a real civil aircraft in climatic environment laboratory has been conducted yet, and no completely-clear parameter which is critical to airworthiness of snowfall has been found. This paper analyzed the characterization methods of snowfall in climatic environmental laboratory. First of all, the literature related to the snowfall was collected from four aspects-meteorological standards, environmental test standards, airworthiness compliance verification methods and foreign civil aircraft test data. Ten characterization methods of snowfall environment were analyzed and extracted. Secondly, with airworthiness compliance verification requirements in the snowfall environment of civil aircraft, temperature, visibility, the total water content, wind speed and the density of snow were used to characterize the snowfall environment in climatic environmental laboratory. The characterization methods obtained in the research can provide references for carrying out snowfall test in climatic environmental laboratory in the future. |
