Hydrogen airships can vary in size, but most commercial airships are around 200 to 250 feet in length. However, historical airships like the Hindenburg were much larger, at approximately 800 feet long.
Airships typically run on one of two things: helium or hot air. Helium is a non-flammable gas that provides lift for the airship. Hot air is used in hot air balloons to provide lift by heating the air inside the balloon.
Blimps are non-rigid airships with an envelope that maintains their shape, while dirigibles are semi-rigid or rigid airships with a structure inside the envelope to maintain their shape. Dirigibles are typically larger and have more internal structure for support and control.
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.
The speed of an airship typically ranges from 40 to 90 mph, depending on the size and design of the airship. However, some modern airships can reach speeds of up to 120 mph.
Just like how a ship floats in the sea because it weighs less than the amount of water it displaces... an airship weighs less than the amount of air it displaces.This is accomplished through the use of lighter-than-air gasses such as helium. In the past hydrogen was used for this, but due to its high flammability this is no longer done. Helium is completely non-flammable and thus is perfectly safe lifting agent.The pilot adjusts the airships bouyancy by either adding more gas, venting gas or by dropping ballast (usually water tanks or sandbags) Once the airship has neutral bouyancy, it can be steered using the elevators and rudders.It is similar in principle to a submarine, which uses 'air' in the ballast to float to the surface and water to descend. Airships rise when 'air' in their hull tanks is replaced with a 'lighter than air' gas, such as Hydrogen or Helium.Just like how a ship floats in the sea because it weighs less than the amount of water it displaces... an airship weighs less than the amount of air it displaces.This is accomplished through the use of lighter-than-air gasses such as helium.

The most famous airships are Hendenburg and Zeppelin.
Airships do use gas, to provide lift.
Airships are usually the shape of a oval. They look like blimps. Airships are usually filled with helium to keep them afloat.

Hydrogen used to be used in airships.
Curly's Airships was created on 2000-10-05.
gas is still used in airships to provide lift.
Hydrogen and helium are two elements that are kinda-sorta interchangeable in airships.
The USA uses airships to protect its sea areas, and to act as spotters, especially against submarines in wartime, and helping with sea rescues in peace time. The Germans and British nations both developed airships, but did not use them for long after some terrible disasters caused by using highly inflammable gas to give them buoyancy to ride through the air.

Hayao Miyazaki has featured airships in several of his films, including Nausicaa of the Valley of the Wind and Castle in the sky. You can also find airships in Howl's moving castle.
