What happens when a hydrogen plane crashes?
Will it explode immediately if it crashes or will it burn without black flames like a normal kerosene airplane would?

What happened in Stuttgart?
ByMannweib
Eight army planes just flew over my house in a row formation towards Stuttgart. What happened there?
Can you fly a Rotorvox with an ultralight pilot’s license?
I was wondering this because (according to my information) the training for an ultralight pilot's license only involves practicing with one aircraft and the Rotorvox is a helicopter. If not, what kind of license do you need?
I urgently need help with chemistry. What does that mean?
Our chemistry teacher has listed all the topics for the 10-hour test. But I don't understand what he means by "(12-1=11)."
Solve accelerated movement with time loss?
ByQHD2016
During a car race, a car's speed is 240 km/h. Due to a penalty, the driver with a constant acceleration of -30 m/s² reduces his speed to 80 km/h and drives at exactly this speed for 300 m. He then accelerates steadily and reaches his original speed after 4.0 s. Determine the minimum time loss…
Can anyone help with physics?
Hello. Can anyone help me with the following task? I've managed to calculate the number of turns. But how do I calculate the thickness (I think that's the diameter) and the length? I would be happy to receive answers. Best regards
Can anyone do chemistry titration?
Can someone help me with this task: "Explain why the equivalence point of a titration curve does not always coincide with the neutral point."
In the event of a crash, the cause of killing should be the impact. It doesn’t matter what happens after that. Let us consider an emergency landing either with fire on board or the danger of fire. Hydrogen is immensely grateful, insofar as the discharge nozzles do not pass through the strong expansion, hydrogen is not only extremely volatile but also light. Explosions would occur, but they would rather occur in the hydrogen cloud escaping upwards. Kerosene is more dangerous here: liquid and also spreads in a burning manner everywhere, for example can also be sprayed in a burning manner.
The H experiments are less but not harmless: The pressure wave could not only endanger the ears, but above all the lungs. Nevertheless, when choosing between hydrogen and kerosene, it is better to be involved in a disaster with hydrogen than kerosene.
Depending on what you call a crash, the term is not clearly defined.
But also here people die regularly by flames. A crash does not necessarily have to be in the ground with the nose, but usually there is still some control.
In the pure combustion of hydrogen, steam is formed, otherwise other things arise due to incomplete combustion products, for example when other chemical compounds are in the aircraft.
If hydrogen burns, the flame is invisible.
Don’t worry.
Whether kerosene or hydrogen:
When both catch fire, it doesn’t make any difference to which plane you chose:
You go there or something.
But you go with hydrogen eco-friendly on it.

No, that’s wrong. The hydrogen would not burn (economically) usefully for its actual purpose: To bring the passengers to the destination alive.
So also here: No matter whether kerosene or hydrogen: Both would be harmful to the environment if they burned meaninglessly.
Have enough people survived a plane fire.
Compared to kerosene,
in a “unfortunate” landing.

Look at the crash of Hindenburg. Then you have an idea of what can happen with hydrogen and oxygen supply.
Hello,
a huge WUMMS!!
And a huge stubborn flame.
In contrast, the crash of the airship Hindenburg was,
a children’s play.
But relatively environmentally friendly.
Hansi
You can’t compare the Hindeburg.
The whole thing burns like a natural gas vehicle.
So hydrogen is very much looking very responsive,
as methane. (CNG)
Energetic a completely different house number.
Hansi
Hydrogen does not burn faster, lighter but not faster, and if the whole thing burns no matter.
Each substance immediately reacts when the activation energy is reached.
Hydrogen is not more dangerous than propane, natural gas, etc.
Have you ever looked at the tank systems for hydrogen and been busy with it? I have already worked with fuel cell systems and there are no special safety regulations for hydrogen which do not apply to other combustible gases. Hydrogen is not particularly dangerous in practical use and has no additional risks to other gases and in this area is also not more dangerous than kerosene.
Rather, hydrogen can also be used in some cases more easily because it can be easily prevented from enriching it outside of leaky tanks because the reaction to water without fire with corresponding catalysts can be carried out easily. In the nuclear power plant area, the candles are called potters.
Hydrogen burns much hotter and faster.
Because he’s going into a reaction right away.
What Knallgas is, I guess everyone knows.
Hansi
It’ll burn both. The Wumms is a cnalll gas reaction to this must be a hydrogen air mixture and this is exactly the case with methane. The ignition energy is smaller yes, but the difference practically does not matter because in this case both substances would ignite.
When a tank leaks hydrogen flows out and begins to burn in the air, which is exactly the same as in a natural gas tank.
That hydrogen is more dangerous than methane is simply a legend based on the Hindenburg crash, but if you look at the Videoas. The explodates also not but burns quickly.
The difference the Hindeburg itself consisted of combustible material and therefore could quickly escape and ignite due to the burning of the material of the hydrogen.
Possibly (I would recommend it Airbus and Boeing) the hydrogen tank is similarly stable, although much larger than the flight recorder. The tank should stay completely.
It’s just like a normal plane crashed.
A hydrogen plane is also broken down into all components when it crashes.
The crash is generally understood as a more or less uncronized flight into the landscape and no the aircraft is not necessarily torn apart and yes you can survive it.
That the plane really falls out of the sky comes as good as never before
see Hindenburg…
but at least the bums would be environmentally friendly compared to kerosene!
It disintegrates into its individual parts.
