Abstract

The present invention reduces a probability of condensation forming in a container for a flying object. Container 12 is a cabin of a gas balloon. Container 12 comprises Main Body 121 that is an airtight container filled with air and accommodating Crew Member H1, and Partition 122 that divides the space in Main Body 121 into Space S1 and Space S2. Partition 122 has one or more narrow Holes H. When the altitude of the flying object increases and Container 12 cools from the outside, air in Space S1 cools more slowly than the air in Space S2. A pressure difference between Space S1 and Space S2 is rapidly equalized by air flow through Holes H, but it takes a long time to equalize a temperature difference between Space S1 and Space S2. Therefore, a temperature in Space S1 becomes higher than a temperature in Space S2, and a temperature in Space S2 becomes higher than a temperature in the space outside Main Body 121. As a result, condensation is unlikely to form in Partition 122 and in the portion of Main Body 121 that forms Space S2.
