It was hydrogen. That's why it caught fire. Modern airships use helium.
The purpose of Helium gas in any airship, including modern airships, is to reduce the overall density and thus provide "lift."
Some use hot air (like a hot air balloon) and others use helium.
If the airship is shrunk by an enemy, the volume of the gas inside the airship will reduce in proportion to the shrinkage of the airship. The gas molecules will be more compressed, leading to an increase in pressure within the airship.
No, the Hindenburg airship was filled with hydrogen gas, not helium. The use of hydrogen was a factor in the Hindenburg disaster, as the highly flammable gas led to the airship catching fire and crashing in 1937.
An airship, made up of a huge gas-filled balloon, and powered by propellers.
The Hindenburg airship was filled with hydrogen gas, specifically about 7 million cubic feet of hydrogen. This highly flammable gas was used as a lifting agent to help the airship float.
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.
Helium has replace hydrogen in airships
Airships and Zeppelins and Observation balloons were used successfully in WW1. They were filled with Hydrogen which is the lightest gas but is also explosive when ignited. (Later, airships began to use Helium) The airship flew because it was filled with a gas that was lighter than the air so that it "floated" in the sky. This is the same theory that makes boats float. For an airship to fly, the weight of the airship and the hydrogen contained it in has to be less than the weight of the Air it displaces. In other words, the Airship takes up space in the air and if it weighs less than the air, then it will fly. For it to move forward, the airship had propellors to push it forward. It also had control surfaces on the tail to turn it and help it climb or dive.
It did for 28 seconds until a fatal gas explosion occured.
an Airship is an aircraft of the lighter-than-air type sustained in the air by gas an aeroplane in a mechanically propelled heavier-than-air flying machine
