中文摘要：

飞艇作为平流层平台可以实现无线通信、空间观测、大气测量以及军事侦察等目的。本文主要结合平流层的环境特点对平流层飞艇动力推进系统的组成和概念进行初步分析，并对飞艇在升空、浮空、回收过程中的飞行控制策略进行探讨，同时简要分析了控制系统的组成、控制难点和飞艇应急控制问题。

英文摘要：

Stratosphere airships can be utilized as platforms for telecommunications, space observation, atmosphere measure and military surveillance. Considering the environmental characteristics of stratosphere, this paper first analyzes the powered propulsion system of a stratosphere airship. Then flight control strategies during launch, floating in the air and landing are studied. Finally, the configuration of the control system, the control methodology and the emergency control are reviewed.
