在-1~-9益的环境温度条件下，采用开放式结冰条件模拟技术可以为民机或军机发动机短舱防冰系统性能试验模拟出合适的结冰气象条件。采用气液两相喷嘴模拟水雾结冰环境时，所采用气体和液体的纯度是过冷水滴产生的先决条件，气液两相压差、风洞吹风速度和试验对象距离是影响结冰气象参数的关键因子。采用改造后的FM-100传感器可实现对结冰气象参数的实时测量。通过升降机构、小角度俯仰和万向轮等辅助结构设计，开放式结冰条件模拟系统可以满足不同试验对象的试验要求，可以适应不同风向的试验环境，具备非常广阔的推广应用前景。

Ground freezing fog simulation technology can generate icing condition for commercial or military air-craft nacelle anti-ice system performance evaluation under -1~-9℃. Purity of water and air used for fog genera-ting is the precondition, icing parameter is impacted by diff-pressure of liquid-gas, wind tunnel velocity and dis-tance between test article and test rig. Rectified FM-100 sensor can be used for icing parameter measurement, rig lift, small angle pitching and universal mechanical structure design make the fog simulation rig can satisfy the re-quirements of different test articles and wind directions.
