Research Abstract

The aim of this research is to study the feasibility of a unique balloon system that floats below the clouds in the Venus atmosphere at the altitude of 10 to 20 km. In that region, the environmental temperature is more than 300 C and atmospheric pressure is 20 Atms.
The structure and material system effective for the Venus balloon were discussed in terms of the severe environmental conditions. A conceptual design showed that both the spherical and the isotensoid structures formed by the filament winding process are preferable candidates for the Venus balloon. The comparison of two structures was performed experimentally using a small test model. It is concluded that analytically the isotensoid body is the best shape but actually the spherical vessel reinforced by polar winging is superior to it.
High temperature electronics is another key technology for the Venus balloon. We organized a High Temperature Electronics Meeting in 1993 and 1994 to survey the related technology. Through the discussions at the meeting, the mission is believed to be feasible on the basis of current available techniques.
