Summary

Broadside depicts two airship designs conceived by Ernst (Ernest) Pétin, incorporating four spherical balloons propelled by manually operated helical screws attached to a large flat surface, the lower part providing promenade decks for passengers. Surrounding text documents the history of ballooning from the Montgolfier brother's flight in 1783 to a description of Pétin's airships, ca. 1850. (Source: A.G. Renstrom, LC staff, 1981-82.)

Hot Air Baloons and Gas Baloons

The main types of airship are non-rigid, semi-rigid, and rigid. Non-rigid airships, often called "blimps", rely on internal pressure to maintain the shape of the airship. Semi-rigid airships maintain the envelope shape by internal pressure but have a supporting structure. Rigid airships have an outer structural framework which maintains the shape and carries all structural loads, while the lifting gas is contained in internal gas bags or cells. Rigid airships were first flown by Count Zeppelin and the vast majority of rigid airships built were manufactured by the firm he founded. As a result, all rigid airships are sometimes called zeppelins. In early dirigibles, the lifting gas used was hydrogen, due to its high lifting capacity and ready availability. Helium gas has almost the same lifting capacity and is not flammable, unlike hydrogen, but is rare and relatively expensive. Airships were most commonly used before the 1940s, but their use decreased over time as their capabilities were surpassed by those of aeroplanes.
