Heilongjiang Mudanjiang A worker riding hydrogen balloon to hit the pine tower was blown away due to improper operation. The good news is that the worker has been safely implemented.
Take the hydrogen ball to pick the pine tower. It has emerged in recent years, but hydrogen balloons have a history of hundreds of years of manned history.
The world's first hydrogen balloon was born in 1780 and was made by French chemist Brack pouring hydrogen into the pig's bladder. The world's first flight hydrogen balloon that does not carry any passengers or cargo was designed and implemented by Professor Jacques Charles in August 1783.
1783 Charles and Robert flew their second hydrogen balloon in a manned flight. After that, the balloon technology developed slowly.
900, airship and meteorological balloon appeared one after another. 900, the German Count Ferdinand von Zeppelin built the first hard airship - Zeppelin .
Airship shines brightly on the battlefield. The technology at that time could not detect the airship, and even if it was detected, it could not be blocked. But the biggest enemy of the airship is the capricious weather.
Then, in 1902, German meteorologist Asman was the first to use rubber balloons to detect the atmosphere.
927, Soviet meteorologists developed the radiosonde method, which opened a new era of meteorological detection and promoted the rapid development of rubber latex balloons.
my country's first latex balloon manufacturer was established in Guangzhou in 1955. It uses domestic natural latex as the main raw material and successfully develops meteorological balloons that can measure clouds and winds using ion deposition.
With the development of technology, air balloon has gone through a process from simple to complex and simple in appearance structure, from circular balloons to streamlined balloons, combined balloons to circular balloons, and the diameter is getting bigger and bigger. This not only increases the balloon's lift-off height, but also greatly increases the reliability of the balloon.
Why can the balloon fly into the sky? The reason why the balloon can float in the air is because the gas density it fills is smaller than the air density. There are two common gases with a density smaller than air: hydrogen and helium and . What is the difference between
hydrogen balloon and helium balloon ? Hydrogen is a lively gas that is flammable and explosive; while helium is an inert gas that does not burn or explode. What should I do if
Hydrogen balloon is out of control? Hydrogen balloons are of storage properties, the size of the balloon volume, controlling their rise and fall.
When it is full of air, the lift is fixed. If you want to decrease at this time, you need to reduce the hydrogen reserve. Just like when we usually blow a balloon, if we have a small mouth, the balloon will gradually become deflated and becomes smaller.
When the worker was riding a hydrogen balloon to pick the pine tower, there were two safety ropes on the ground and on the branches to prevent the hydrogen balloon from being scraped away. If an accident occurs, pulling the "zipper rope" to release hydrogen can save yourself and make the hydrogen balloon land slowly.
So, how high can a hydrogen balloon fly? The current answer is that it is 10 kilometers above sea level, which is "one head taller" than Mount Everest . This number is the upper limit of flight altitude of meteorological balloons that are commonly used. A hydrogen balloon that exceeds this height will eventually explode.
The higher the balloon fly, the air pressure of the outside air gradually becomes smaller than the air pressure inside the balloon, and the balloon will rise bigger and bigger, eventually exceeding the limit of the balloon's skin, resulting in rupture.
The ordinary toy hydrogen balloons we usually play with are limited once they fly away, and most of them will explode after more than 2,000 meters.
. Many balloon toys sold to children on the roadside are filled with hydrogen. Because helium production is more complex than hydrogen, it is cost-effective and expensive, so many people are unwilling to inflate it with helium.
Finally, I would like to remind everyone to be cautious when buying hydrogen balloons and pay attention to safety when playing.
