Abstract

Stratospheric airships are the frontier research focus with strong innovativeness and huge technical challenges. Stratobus is the only on-going large long-endurance stratospheric airship project abroad. The basic scheme and overall progresses of Stratobus are first summarized, followed by generalization and analysis of the technical proposal and development status of the key technologies, including envelope materials, solar cells, regenerative fuel cells, and gondolas. Additionally, three important balance conditions determining the design feasibility of the stratospheric airships are analyzed using numerical simulation, involving balances between buoyancy and gravity; power production and power consumption; and thrust and drag. Some experiences and lessons from the Stratobus project are finally presented, providing reference for the design of and research on stratospheric airships.

Key words： Stratobus stratospheric airship; envelope materials; energy system; solar cells; overall scheme
