Thermodynamic Study for Venus Balloon

Abstract:

The environment of Venus surface is extremely harsh, while the lower attitude atmosphere is similar to the Earth's stratosphere, so the balloons can be exploited extensively for Venus exploration. First, the Venus atmospheric environment is described with mathematical model. And the Venus balloon thermodynamic model is established. Then, the floating process of a helium prototype balloon, whose floating altitude is 35 km, is numerically examined by this model. The results show that (1) Wherever the Venus balloon releases at the altitude between 30km and 40km, it could reach floating altitude quickly and keep long-term floating; (2) The balloon system temperature should endure the temperature between 440 K and 520 K; (3) Its instantaneous maximum speed is less than 10 m/s.
