What are the advantages of airships?

With the progress of aviation technology, airship has begun to get people's attention again. Although compared with airplanes, airships are big and stupid, inconvenient to operate, slow in speed and vulnerable to wind; However, the airship also has its outstanding advantages, such as vertical take-off and landing, long air time, long hovering time or slow moving speed, no oil consumption, low noise, little pollution and good economy. Moreover, with the wide use of helium filling the airship, the safety is greatly improved.

It is estimated that the cost of transporting a ton of cargo by airship is 68% less than that of airplane, 94% less than that of helicopter and half less than that of train. Therefore, countries all over the world began to develop airships, and new models of modern airships with advanced technology emerged continuously in 1990s, such as British Sentinel series, German LZ-07, Russian Scientific Static series, China Zhonghua and Shanghai Daejeon CA-80 series soft manned airships and so on. Modern airships have been widely used in modern aerial survey, photography, advertising, lifesaving and air movement.
