摘　　要：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 snow are the key factors to affect the safety of the tethered - balloon system. To enhance its capability on snow - melting and defrost under cold and rainy weather, we presented a new method on loop heating system of the gas in the fixed - tethered balloon. By establishing different beat - transfer models of gas and the surface area in different temperature, wind speed and different snow conditions, the paper calculated the heat power needed in typical and severe weather, simulated and analyzed actual effects on the snow - melting and defrost by gas - heating in balloon, which offered a good reference in evaluating this experiment.
