Zeppelin

Zeppelin refers to a type of rigid airship named after the German engineer Ferdinand von Zeppelin and the company he founded, Luftschiffbau Zeppelin. A Zeppelin consists of a rigid framework of rings and joints that maintains its shape independent of the lifting gas, with multiple sealed gas cells inside. Propulsion is provided by several engines driving propellers mounted on the hull, and steering is achieved with rudders and fins. A gondola or control car houses the crew and passengers. Historically, early Zeppelins used hydrogen, a light but flammable gas; later designs used non-flammable helium where available to reduce fire risk.

The Zeppelin concept was developed in the late 19th and early 20th centuries, leading to the first successful airship, LZ 1, in 1899. The fleet expanded through larger ships such as Graf Zeppelin (LZ 127) and culminated with the Hindenburg (LZ 129) in the 1930s. The Hindenburg disaster in 1937, when the airship burned while docking in New Jersey, significantly diminished the use of large passenger airships and marked the end of an era in commercial air travel. Despite the decline, the Zeppelin concept influenced airship design and continued in specialized applications.

In the late 20th and early 21st centuries, Zeppelin Luftfahrt GmbH and related firms revived interest with semi-rigid airships under the Zeppelin NT line, used for tourism, advertising, research, and patrols. The term Zeppelin remains a generic reference to this family of airships, and the name persists as a brand associated with airship design and related tourism.
