摘　　要：分析了金星独特的大气环境,归纳了影响金星气球飞行的主要环境因素,并建立了数学模型.依据金星气球的投放、飘浮程序,设计了金星原型氦气球,设计驻留高度为35km.建立了金星气球热动力仿真平台.计算结果表明:金星气球在30～40km高度释放,可快速到达驻留高度并作长期飘浮;金星气球系统的温度范围为440～520K,最大速度低于10m/s.这为进一步开展对金星气球的研究提供了依据.The Venus atmospheric environment was described with mathematical model. The Venus balloon thermodynamic model was established. Then, the floating process of a helium prototype balloon, of which the floating altitude was designed as 35km, was numer- ically designed by this model. The results show that when the Venus balloon is released at the altitude between 30 km and 40 km, it can reach floating altitude quickly and keep long- term floating, the balloon system should endure the temperature between 440 K and 520 K, its instantaneous maximum speed is less than 10m/s. This research would provide basis for the further development of Venus balloon further development.
