How Do You Use Helium In An Airship?
Airships were originally filled with hydrogen, which is cheaper but more flammable than hydrogen. The discovery of natural gas fields in the United States has allowed American airships to use helium since the 1920s. The following steps will explain how to fill an airship with helium. Step 1 Calculate the amount of lift that will be provided by the helium. One cubic meter of pure helium gives about one kg of lift. The lighter helium will force out the air as it fills the blimp. Step 2 Spread the envelopes on the hangar floor. The envelopes are very strong and made from a combination of synthetic materials such as Dacron, Mylar, polyester and Tedlar. A modern airship consists of an outer envelope that protects the inner one from the elements. The inner envelope actually contains the helium. Step 3 Place a net over the envelope and hold it down with sand bags. Have plenty of trained personnel available as inflating an airship requires constant supervision. Step 4 Feed the gas into the inn
