几十年来，飞艇被贬低到仅仅被认为是一种好奇心的程度，现在它们似乎又重新出现了。其主要原因与材料、空气动力学、能源和推进技术的最新进展有关。飞艇也将自己呈现为绿色友好的空中交通工具，特别是如果考虑太阳能飞艇。它们能够长时间保持在空中，这也扩大了它们所适合的使命剖面的范围。在这里，我们集中在一个关键的概述飞艇推进机制。其中包括过去，现在和未来的飞艇推进技术的详细概述。不同的概念被重新审视，飞艇的几何形状和飞行力学之间的联系是为不同的推进系统机制。
After a few decades in which airships have been depromoted to the level of being only considered as a mere curiosity they seem now to reappear. The main reasons for this are related to the recent progress in technology of materials, aerodynamics, energy and propulsion. Airships are also presenting themselves as green friendly air vehicles, in particular if solar powered airships are considered. Their ability to remain aloft for long time periods have also expanded the range of mission profiles for which they are suited. Herein we have concentrated on a critical overview of propulsion mechanisms for airships. These include a detailed overview of past, present, and future enabling technologies for airship propulsion. Diverse concepts are revisited and the link between the airship geometry and flight mechanics is made for diverse propulsion system mechanisms.
