Stratobus平流层飞艇项目研究进展与仿真分析

Development status and simulation analysis of stratospheric airship Stratobus

平流层飞艇是当前的前沿热点研究方向,创新性强、技术挑战大。针对国外公开在研的大型超长航时平流层飞艇项目Stratobus,首先对基本方案进行总结分析,梳理总体研究进展,然后归纳剖析囊体材料、太阳电池、可再生氢氧燃料电池、吊舱移动系统等核心关键技术方案和研究进展,在此基础上,通过数值仿真,对决定平流层飞艇总体方案可行性的浮重平衡、推阻平衡、能源平衡进行综合分析,提出了Stratobus项目发展的启示,为平流层飞艇总体设计和研究发展提供参考借鉴。

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.
