It is precisely because of this way that when the rocket is launched, everyone will see a lot of water sprayed directly at the bottom of the rocket, but many people don't know why. Today we will decipher why the rocket will spray water after launch.
Rockets can't be launched into the sky until they are ignited, so will water spraying put out these fires, so it can't be guaranteed to be launched?
But since this method has been chosen, it shows that it is reasonable. It can not only prevent rockets from being launched into the sky, but also solve some problems.
First of all, the first reason is that spraying water at the bottom of the rocket can cool down. If the rocket wants to fly into the sky, it needs a lot of fuel. After all, it takes more fuel to push this big guy into the universe.
The heat generated by these fuels during the ignition process can reach 3500, which can melt many things, so the material selection of rockets is also very strict.
However, it still has a certain impact on the surrounding facilities and personnel, so spraying water is first to cool down. In order to ensure the smooth launch of rockets, some manned rockets and launch vehicles, and ensure the safety of people inside, measures such as cooling must also be taken. When it comes to cooling, water is definitely the first choice.
The second reason is to reduce noise. As we all know, there is a limit to the sound that people can hear and the sound that affects people's ears. Noise will make people more agitated, and excessive noise will even endanger human health.
When the rocket is launched, the noise can reach 220 decibels, which is very high. After all, the sound of 130 decibels can easily break the glass. If people directly hear the sound of 220 decibels, the consequences are unimaginable. There are many ways to eliminate noise, and water is one of them. In addition, it can cool down before, which is also a way to kill two birds with one stone.
How does water eliminate noise? In fact, water molecules can absorb some sounds, and when spraying water at the bottom of the rocket, they can use decibel energy like other things, and use it to convert the decibel energy of sound into heat energy, thus eliminating noise.
The last reason is that water is actually a cheaper way. Rockets have a lot of cooling or silencing needs, and the cost of water in 400 miles is relatively small.
It can not only solve the problem but also save money. Why not choose water to cool down? The launch of the rocket led to the exploration of space. What scientists need to do is to provide more technical support for the exploration of Heaven.
Launching is very common now. Although many people don't understand why 400 tons of water should be sprayed, these are actually for more protection.
Through the exploration of scientists, numerous theoretical supports and the final experimental results, it is proved that this method is feasible. Therefore, spraying water at the bottom of the rocket is not only to cool down, but also for many reasons.
