The Hindenburg disaster
Hydrogen used to be used in airships.
There never were hydrogen powered airships. Hydrogen provided lift, not propulsion. Propulsion came from combustion engines using diesel or gasoline.
Helium has replace hydrogen in airships
No, Hydrogen is a gas. The verb "fly" can not be applied to a gas.
The gas that helium replaced was Hydrogen
The gas was Hydrogen.
An example of a gas element is helium, which is a noble gas commonly used in party balloons and airships.
Hydrogen gas is highly flammable and poses a significant safety risk. Therefore, helium gas is commonly used in airships today as it is non-flammable and safer. Additionally, helium has a higher lifting capacity compared to hydrogen, which allows for better control and stability of the airship.
Airships do use gas, to provide lift.
In their early history, buoyant airships (zepellins, blimps) were filled with hydrogen, a highly flammable gas. Since the Hindenburg disaster, hydrogen has been supplanted by helium, a much more expensive material, but one that is inert and hence much safer.
the gas that helps airships is i hate you wikianswers.com
Using hydrogen in airships is considered dangerous because hydrogen is highly flammable and can lead to explosions if exposed to air. This risk was famously demonstrated by the Hindenburg disaster in 1937, where an airship filled with hydrogen caught fire and crashed. As a result, helium is now the preferred gas for use in airships due to its non-flammable nature.
