平流层飞艇的能源技术和平衡分析

Power Technology and Energy Balance Analysis of the Stratosphere Airship

平流层飞艇作为近空间对地观测平台的一种实现方案,主要依靠自身庞大体积产生的静浮力而不像其它飞行器依靠相对空气运动产生升力,所以飞艇能够以较慢的速度飞行甚至能够在空中长期保持定点悬停即相对地面静止。具有长时间在平流层自主飞行的能力,是平流层飞艇设计的一个重要目标。文章对平流层飞艇能源系统的构成、部件及能源平衡分析方法作了介绍。

The stratosphere airship which is a solution for the earth - observation platforms in the Near Space, unlike aircraft, generate lift through the buoyancy instead of through the aerodynamics . Airship can fly at very low speed, even it can station at a fixed area for a long time. The ability to fly automatically for an extended duration of time at high altitudes has been an elusive goal. Addressed in herein are the structure of the power system and the method of energy balance analysis.
