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.
Today's blimps are not filled with flammable hydrogen gas like Hindenburg was, but normally the non-flammable helium.
Zeppelins.
The gas was Hydrogen.
Airships today are used for advertising and carrying TV cameras to film large special events like auto races.
machine guns, airships, airplanes, anticraft gun, poison gas, and tanks
Airships do use gas, to provide lift.
There never were hydrogen powered airships. Hydrogen provided lift, not propulsion. Propulsion came from combustion engines using diesel or gasoline.
the gas that helps airships is i hate you wikianswers.com
gas is still used in airships to provide lift.
Hydrogen used to be used in 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.
Modern airships use Helium for lift which is non-combustible whereas in the past airships such as the Hindenburg used Hydrogen for lift which is highly combustible. In addition, modern airships take advantage of new alloys and polymers which give them a much stronger airframe.
Today's blimps are not filled with flammable hydrogen gas like Hindenburg was, but normally the non-flammable helium.
in the twetieth century for the most part but they are still in use today like the good year blimp
Zeppelins.
because hydrogen used to be in those airships and since hydrogen is flammable it was very dangerous
Airships move primarily through the use of buoyancy and propulsion. They are filled with a lighter-than-air gas, such as helium or hydrogen, which allows them to rise. For horizontal movement, airships are equipped with engines and propellers that generate thrust, enabling them to steer and navigate through the air. The combination of buoyancy for altitude control and propulsion for forward movement allows airships to travel efficiently.
