They are explained with the help of a balloon. Men aboard the balloon. The balloon ascends. The upward and the downward movement of the balloon is explained. An airship is like a free balloon. Functions of rudder, elevators and other parts of an airship are explained. Helium is used to inflate the envelope of the airship. Men work nearby.
From a U.S. Navy training film in the United States on working of airships. A diagram of an airship. The envelope of the airship consists of helium and air. The pressure of outside air becomes less when helium is filled in the envelope. As helium expands, air is released through air valves. In the same way, when the pressure of outside air increases, then helium is released. If proper pressure is not maintained, the airship can loose its shape. Animation shows the working and functions of the airship. The ascent of an airship. The process of the escape of gas is also explained.
From a U.S. Navy training film in the United States on the working of airships. Specifications and designs of airships are explained. Fleet type airships are called ZP2K airships.
