冰霜和雨雪是影响系留气球系统露天安全系留的关键因素,为增强系留气球在寒冷气候和雨雪天气下的除冰融雪能力,论述了一种阵地式系留气球内囊气体循环加热的地面除冰雪方法。通过建立不同大气温度、风速和不同积雪速度下内囊气体与球体表面积雪的换热模型,计算了典型冰雪天气和恶劣冰雪天气下的需用加热功率,模拟分析了不同气象条件下内囊气体加热除冰雪方法的除冰雪效果,对于综合评估除冰雪试验的实际效果具有很好的参考意义。
Frost and rain and snow are the key factors influencing the safety of tethered balloon system in open air. In order to enhance the deicing and snow melting ability of tethered balloons in cold and rainy and snowy weather conditions, a gas tethered balloon balloon circulation Heated ground ice and snow method. Through the establishment of the heat transfer model of the snow in the inner bag gas and the sphere surface under different atmospheric temperatures, wind speeds and different snow velocities, the heating power under typical ice and snow conditions and severe ice and snow conditions are calculated. The effect of deicing and snow removal by the method of deiceration with gas in the pocket is very good for evaluating the actual effect of deicing and snow test.
