Chapter 717: "Alien"

phone-reading
The range of the naval gun is too far.
It is impossible to observe with the naked eye.
However, modern technology is very developed.
There are satellites in the sky. There are frigates at sea. There are also nuclear submarine tracking underwater. Trinity. Attention throughout.
The live video can be transmitted in the first time.
"preparation!"
"put!"
"Boom!"
There was a deafening noise.
Even wearing thick earmuffs, it feels very shocking.
The huge battleship also obviously paused aside. It feels like being pushed hard by someone. Almost sat down.
Fortunately, everyone is mentally prepared. I have long grasped the railing or handrail around me firmly.
The recoil of large-caliber naval guns is well known. Absolutely horrified.
If he didn't take precautions in advance, it would not be a surprise to sit on the ground with a shock.
In fact, with Wang Bu'an's ability, it is entirely possible to make a bigger caliber.
What is 499 mm?
999 mm can be made.
Even 1999 mm can be made.
However, these data are useless. Because no one can withstand its recoil.
The caliber ratio of this naval gun is very large. Reached 75 times the caliber. Its advantage is that it has a very long range. The impact of the shell is very strong. It can even penetrate a two-meter-thick homogeneous steel plate when shooting straight.
Everything has advantages and disadvantages. The negative effects brought about by this are also obvious.
The number of propellant charges is very large. The chamber pressure is very high. The recoil is very large.
According to calculations, if it is a salvo of three naval guns, the displacement of the entire battleship will reach ten meters.
If nine naval guns fired three rounds in turn, the displacement of the battleship would exceed 20 meters.
In other words, the battleship will be forced out ten meters.
One can imagine how powerful the recoil of the naval gun is.
If it is on land, the reinforced concrete base must be at least ten meters thick!
If there is no such standard, I am afraid that after a few shots, the entire base will be shaken loose, and then collapsed, and finally finished.
"Boom!"
"Boom!"
The naval gun continued to fire.
A hurricane passed by, very violent.
This is the death hurricane formed by naval gun fire. As long as it is a cannon with a caliber above 300 mm.
However, there is basically no artillery on land with a caliber exceeding 300 mm. Only naval guns are more common. Therefore, such death hurricanes generally appear on larger warships.
Why is it called a hurricane of death?
Thought it would overturn you directly into the sea.
Its impact is enough to shatter your internal organs. You don't need to fall into the sea, you're done.
When the naval gun is launched, there can be no moving objects within a radius of 50 meters. Otherwise, they will all be pushed into the sea. The surrounding railings will also be broken.
Wang Bu'an didn't believe in the allusion that the officers and soldiers of the Beiyang Navy put clothes on the gun barrel. Unless the Beiyang Navy really has no discipline.
Otherwise, once the naval gun fires, these clothes will be directly shattered by the shock and disappear completely.
The pile of debris on the deck is a dead end.
"The firing range is 138.24 kilometers."
"Deviated 37.5 meters from the target."
"The depth of the explosion is 8.40 meters."
Soon, the observation point sent back detailed data.
The range does not seem to be ideal.
The accuracy is not ideal.
The explosion depth seems to be substandard?
According to theoretical design, the range of this naval gun should be more than 200 kilometers.
Why is it less than 140 kilometers?
Either the inclination angle of the muzzle is not enough.
Either the charge is not enough.
"The angle is thirty."
"Five packages of medicine."
Chen Xiangmin saw the problem at a glance.
The angle of the muzzle is not high enough, and the range is naturally not far enough. The trajectory of the shell is parabolic.
According to the design of the naval gun, up to eight propellant packs can be inserted. But in the end only five were inserted. It shows that the number of propellant is far from enough. The chamber pressure is too low, and the range of the shell is naturally close.
Why didn't you put eight propellant packs? It is entirely for safety reasons. For fear of accidents such as explosion.
After all, today is just a preliminary test. Just test the basic performance of the battleship.
The maximum range of a naval gun belongs to the extreme performance and can only be carried out after the basic performance test is completed.
Extreme performance has negative effects. Harm to equipment and facilities.
There is no doubt that the recoil brought by the eight propellant packs will definitely burst even more.
Will it shatter all the equipment and facilities on the battleship?
No one can guarantee it. It can only be tested step by step.
There is no way to solve the problem of accuracy.
This is the most ideal accuracy.
After all, with such a long range, a deviation of thirty or forty meters seems normal.
If you want precision strikes, you can only use missiles.
It has to be the kind of laser end-guided.
After the missile arrives, someone else must illuminate the target with a laser.
If there is no external laser guidance, the shooting accuracy of the missile may not be as good as the artillery shell. The missile is certainly not as powerful as a cannonball. Not to mention the cost.
Don't look at the 499 mm diameter is very large. In fact, its shell manufacturing cost is really not high. UU reading www.uukanshu.com definitely does not exceed RMB 50,000.
The price of a medium-range missile, even the beggar version, is more than RMB 500,000.
The damage caused by firing 10 shells is definitely stronger than a missile.
The depth of the explosion is entirely a fuze problem. Just make some adjustments.
"Boom!"
"Boom!"
The other naval guns were tested one by one.
Each naval gun fired one live round and two rounds for exercises.
Why not launch more?
Mainly considering the life of the naval gun barrel.
It seems that the barrel of this super large-caliber naval gun has a very short lifespan.
Generally speaking, it is about 300 rounds.
If more than 300 rounds were fired, the internal injury of the barrel would be very serious.
So, when it's okay, use it sparingly. Don't have to fight, the gun barrel is already scarred.
Although Wang Bu'an has repeatedly assured that the barrels produced by Tyrannosaurus Rex will never be less than 100,000 rounds. You can practice hard at ordinary times. However, the navy leaders do not believe it. Including Guan Hongru. They trust their own experience more. Naval guns can only be used when they are most critical.
"Toot!"
"Toot!"
The phone watch prompts Yan Ruzi to call.
This beautiful female doctor always felt a little awkward with Wang Bu'an.
If it is not necessary, she will never be in the same position as Wang Bu'an. Even she gave birth to two children to Wang Buan. Even these two children have the surname Yan. In the future, I will inherit the incense of the Yan family.
"Beauty, what's the matter?" Wang Bu'an liked to tease Doctor Yan. No matter what time it is.
"We have a group of strange guests." Yan Ruzi said in a low voice.
