The process of filling of the envelope of an airship with helium is explained in the United States.

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.
