| Abstract: |
| The paper aims to build a snow simulating technique and provide technical supports for aircraft snow test in climatic environment test facility. Based on the comparative analysis and tests on mechanisms of natural snow and its laboratory simulation, key factors of simulating snow were proposed. In combination with theoretical analysis and experimental study, the optimal water particle diameter and the cooling loads of simulating snow in facility were elucidated. The paper built the simulating snow technique for the climatic environment test facility. Both intensity and quality of the snow met the requirement on snow environment compatibility test of aircraft and other weaponry. The environmental simulating snow technique is practical and effective, and could be used to study the snow environment adaptability of aircraft and other weaponry in facility. |
