Super Weapon Swap System

When the artillery appeared in human history, all kinds of officers and heads of state were particularly obsessed with the artillery. The scene of artillery firing was enough to shock people to an unprecedented level.

On the ground, the largest caliber is 155 mm artillery, and the shooting movement is earth shaking. When this 406 mm heavy artillery shoots on the ground, it is like a mountain collapse and earth crack, with no light in the sun and moon!

Qin Guan also felt it for the first time. Although he had seen battleships firing on TV before, it was a picture after all. Now it is also a picture. However, the ground under his feet is shaking, the picture on the wall is shaking, and the roar in his ears is unacceptable. This feeling can't be known just watching TV.

Even Dr. bull changed his face. Unexpectedly, the power of the propellant, which lengthened the barrel and developed with modern technology, was so fierce!

If he didn't come in, I'm afraid he would be injured outside now. If this huge shock wave hits him, he can damage his internal organs. Isn't that terrible?

The whole ground was shrouded in smoke. Part of the smoke was from the muzzle and part of the smoke was blown by the gas from the gun door. In short, nothing could be seen. The scene was blurred, and even gave Dr. bull an illusion that it would not be his own cannon? So heroic?

Fortunately, the sharp north wind soon dispersed the smoke. The outline of the super cannon appeared in front of him again. Everything remained the same. It was still so majestic and his cannon.

Dr. bull suddenly turned and strode out. He couldn't wait to see what the cannon looked like after it was fired.

The firing of artillery is quite spectacular. After firing, there will be another extremely important task, cleaning the bore. If it is not cleaned, the bore may be blasted in the next launch. It is also very difficult to clean this kind of artillery with a barrel of more than 100 meters. Fortunately, the barrel is thick enough for thin people to drill in and wipe, so that the artillery can rise slightly at an elevation and drill in from the muzzle, You can wipe it back all the way.

Dr. bull expects a cannon with a one meter thick barrel to be considered from various angles. After it is thick, it will be easier to wipe the barrel. Moreover, if the newly cast cannon can also be made into a smooth bore gun without rifling, it will be easier to wipe it.

Qin Guan didn't run out immediately. After the shells were fired, the later tracking data began.

The ground measurement and control network found this high-speed flying object. After taking off from the ground, it immediately reached the speed of seven kilometers per second. In flight, it continued to accelerate and accelerate. The rocket engine at its tail kept pushing it, continued to accelerate, increased altitude and acceleration, and the trajectory began to bend until it reached the highest point, If the speed is appropriate, it is an artificial satellite. If it is not appropriate, it is that the shell falls down again.

Can you launch a satellite with a cannon? Expensive experiments, if they always fail, will inevitably attract criticism. In particular, in the aerospace system, some old comrades can't turn their thinking around.

This is known from the development of hydrogen and oxygen engine in those years. Some old comrades were afraid of failure and obstructed the project. After the failure of the first launch, there were more voices. Fortunately, Qin Guan's support gave designers confidence. Later, successive successes made this doubt disappear.

Now, now they want to launch satellites with artillery, that is to grab the rice bowl of rocket experts. As we all know, the rocket structure is complex, the cost is huge, and the cost of launching is very high. As for artillery, it is very simple to launch once. This is definitely a low-cost space launch method. Once successful, it will lead to earthquakes in the whole industry.

Therefore, rocket experts have doubts. If the experiment fails, their opposition will be stronger. Qin Guan looked forward to the follow-up progress.

"The data looks good at present," said Qin Guan. He doesn't understand anything else. Just look at the coincidence between the observed curve on the screen and the predicted theoretical curve. Now the picture has been switched to this picture.

"Yes, it seems to be going to succeed."

If it is an ordinary shell, the speed will become smaller and smaller after it goes out of the muzzle. The speed out of the muzzle must be greater than 8000 meters per second before it can reach the first cosmic speed after it goes to heaven. However, the current shell is a rocket booster. After it goes out, it can continue to speed up. On the other hand, the mass of the rocket booster section decreases continuously during the ignition process, According to the most basic kinetic energy formula, we can know that its speed will increase. Now, under these effects, the shell continues to fly into the sky.

"It has reached the predetermined speed and the launch is successful!" the scholar looked at the image nervously next to him, and finally shouted, it's successful! Even laymen can see that the launch was successful!

"Quickly, find a radio and listen to his broadcast," Qin Guan said.

This kind of launch is a near earth satellite. It takes only 84 minutes to circle the planet. Therefore, when it circles over its own head, it should be able to hear the sound of the radio, right? The first man-made satellite in the Han Dynasty was like this.

"Wait, you see, those data seem to be wrong?" the scholar asked.

There were no Aerospace experts present, and Dr. bull had gone out to see the cannon. It seemed to him that the cannon was more important than whether the satellite was in orbit. As long as the cannon was intact, he could continue the experiment.

Now, what do you mean by constantly returning error messages?

"Well, connect me to the measurement and control center." Qin Guan said, "ask them about the situation there."

Although it is a wilderness here, the communication has been laid. The scholar soon called. When he learned about the situation, his face was also very ugly. He said to Qin Guan, "the measurement and control center has not detected any signal of this satellite. It may have been scrapped."

The launch was successful, but after it went up, it couldn't work. It was a real space junk.

Qin Guan listened for a while. Launching a satellite with a cannon is a fatal factor in principle. The acceleration in the initial stage is too large. Don't even think about it. Even electronic equipment may fail under that acceleration. To use an inappropriate metaphor, the current in it is formed by the flow of electrons. Under this acceleration, The direction of electron flow inside may change under inertia, so the circuit will naturally fail.

"Let's go and talk to Dr. bull about this problem." Qin Guan said. When Dr. bull said that there was no problem with gun launched missiles, Qin Guan agreed. Now think about it, although the principle is the same, the quantity value is different. The acceleration inside the super cannon is much greater than that of the tank gun launched missiles.
