摘　　要：结合低空气象条件,详细分析了飞艇的热环境情况和影响因素,并运用计算流体力学软件FLUENT及其提供的接口编制的并行的UDF程序,对标准飞艇模型进行了数值模拟计算,获得了全天时飞艇内部、蒙皮表面的最高温度、平均温度等分布情况。该方法具有较高的精度,对于指导飞艇材料的选取,以及推广到平流层飞艇的热环境分析具有指导作用。The thermal environment and influencing factors of low-altitude airships are analyzed in detail by combining the weather con-ditions of low altitude with characters of low-altitude airships.A numerical simulation approach is used to compute a airship model which uses computational fluid dynamics（CFD） software FLUENT and compiling parallel UDF programs with its providing interfaces.The results predict the distribution of temperature including the highest temperature and average temperature of airship in boat and shin surface.This method has higher accuracy,the results well conduct the material selection used in airship shin and research the thermal environment in the stratospheric airship.
