After Zhang Xu heard this, he fell into deep thought. He was not sure whether he could withstand the impact of Mach 33, which is 33 times the speed of sound, up to meters per second.
After activating the python transformation, Zhang Xu's own movement speed was only 483 meters per second. Although his body did not reach the limit, the gap between his own speed and the speed of the missile was too big, so naturally he did not dare to take risks.
"It's better to put me into the explosive warehouse. Although you can't see the outside situation this way, I will time it according to the time. 1500 kilometers, which is about 200 seconds." Zhang Xu said seriously.
The missile did not reach Mach 33 all the way, but started to accelerate after it penetrated back into the atmosphere. 200 seconds is only an approximate. If it is to be accurate, it still needs to be calculated by the experts in front of you.
Fan Yucheng looked at an officer not far away. He remained silent throughout and slowly said, "Old Lu, why don't you modify the pulse fuze circuit at some point? Let the missile-borne computer transmit the signal to the explosive chamber. Just emit a beacon when you reach your destination?”
"Yes, but it will take time." The officer nodded. It is indeed feasible to modify the missile-borne computer to give a signal light to the explosive warehouse. If it is close to the target, it will give a signal to Zhang Xu. He doesn't understand the principles of these weapons. It's better to leave these to professionals. He is only responsible for bringing his compatriots back!
"What do you think?" Fan Yucheng cast a look. Zhang Xu said that there was no problem. Squidward might not land for more than ten days. As long as the modifications were made in time, he wouldn't have too many problems. By the way, he also had to plan the route to transfer these hundreds of thousands of people.
"Okay, let's do that. But you are not familiar with country R. Why don't you bring Qimeng with you? She has studied in country R and can help you?" Fan Yucheng stood up slightly and looked at Liu Qimeng again. , asking for their opinions.
Strategic missiles refer to the type of missiles that are precisely arranged. They require strict calculation of ballistic trajectory, target location, external factors, etc. Basically, the distance from the target is not less than a kilometer, and it is very accurate. Among them are the well-known atomic bombs, hydrogen bombs, Neutron bombs, intercontinental ballistic missiles, etc.
The largest of them can weigh up to one hundred tons. Even if it is not the highest-standard strategic missile, it is not a problem to fit a few people into the explosive warehouse. Tactical missiles were not chosen because they were inaccurate, too small, and could not hold people in the explosive chamber. The most important reason was that they were not concealed enough.
Everyone looked at Liu Qimeng. It was obvious that she had no intention of refusing. Fan Yucheng nodded. Now that the plan was roughly drawn up, the next step was to wait for the strategic missiles to be deployed.
…
Zhang Xu heard the sound outside. He slowly opened his eyes. The surroundings were dark. At this moment, he was standing in the explosive chamber of an intercontinental missile, with Liu Qimeng beside him.
Since the explosive warehouse was previously filled with high-density liquid explosives, it was sealed. After removing the fuel, they entered the warehouse wearing a pair of oxygen tanks.
The lung capacity of evolutionaries can far exceed that of ordinary people. Zhang Xu, Liu Qimeng and the others are also testing how many oxygen tanks can sustain the two of them for how long.
The explosives warehouse slowly opened, and a ray of white light came in. Zhang Xu squinted his eyes, and he slowly climbed out of the warehouse.
There were several familiar faces outside, and Zhang Xu's face darkened because he saw Gao Peng.
"Why did you bring him here?!" Zhang Xu looked at Fan Yucheng and others with a questioning tone.
Ma Jin opened his mouth to speak, but Gao Peng was the first to say, "Oh Brother Xu, I'm here already, and I also want to go to Country R with you."
"No!" Zhang Xu said categorically. Going to other countries during this post-apocalyptic time period made many people think that this was a kind of invasion taking advantage of the situation.
This will bore many people, and other civilian evolvers will not welcome evolvers from other countries. Why are they here, come here to grab supplies?
In the face of foreign evolvers, one thing people from other countries can do is to drive them away!
Gao Peng looked at Liu Qimeng behind Zhang Xu, scratched his head in embarrassment, and then he forced Zhang Xu out of the door.
Seeing no one around, Gao Peng hesitated and said: "Brother Xu, I... this..."
"If you have anything to say, please tell me." Obviously, Zhang Xu was a little impatient. He didn't want to see Gao Peng get into trouble again, so his attitude was unusually firm.
"I like Liu Qimeng, just let me follow you." Gao Peng said quickly, but Zhang Xu heard him clearly.
He was silent, helpless, sighed again, and finally patted Gao Peng on the shoulder and said: "Okay, you can participate in the mission this time... but you have agreed to follow me closely."
"Brother Xu, I love you to death..." Seeing Gao Peng happy, Zhang Xu just smiled, and then put on an expression of disgust: "Come on, you go love your Liu Qimeng."
The two went back quickly. After Zhang Xu's suggestion, Gao Peng was able to participate in the mission. Only Liu Qimeng, who looked indifferent, continued to stay in the explosives warehouse.
Time waits for no one, and with the addition of Gao Peng, the weight calculation begins again. Whether it is the weight of the human body itself or the weight of oxygen tanks and flying equipment, these must be reconsidered.
However, Zhang Xu refused flatly, because they were evolutionaries. He himself could glide with the help of blood and bone wings, and Gao Peng could fly himself. Two of the three were not afraid of high altitudes.
In the same way, although the explosive chamber must be sealed during launch, a few ordinary people would definitely be suffocated to death within a few minutes, but for evolutionaries, there is no need to deliberately prepare for a flight of just a few minutes. .
This is also the suggestion that Zhang Xu tested.
The majestic ballistic missile springs up from the horizon like bamboo shoots after rain. Its black-gray body is like a jungle panther ready to go. This is the Dongfeng M-397 ballistic missile, which is relatively cheap among ballistic missiles, and One of the models available for sale, it reveals its entire body as the silo rises.
The Dongfeng M-397 ballistic missile is powered by a three-stage liquid fuel rocket with a maximum range of about 7,500 kilometers. It can carry a single warhead or multiple smaller warheads, induced warheads and re-entry vehicles.
The liquid fuel uses compressed liquid hydrogen and liquid oxygen. The advantages are that the specific impulse is as high as 457S, no carbon deposits, and no pollution. It is the best choice for the upper stage of multi-stage rockets. However, the disadvantages are also obvious. Under the same volume, the molecules of the liquid fuel The density is definitely not as good as solid fuel, and the fuel tank will be larger.
The Dongfeng M-397 ballistic missile applies many technologies, such as small-momentum space rocket technology that other small countries are coveted. It is also a nightmare for many small countries.
To put it simply, small-momentum space rocket technology can change its trajectory in mid-air and disrupt the enemy's computer system. This change can make the opponent's anti-aircraft missiles unable to intercept it.
This is why Zhang Xu is still afraid of Country Z's cutting-edge weapons even if he has become such a high-level evolver. It will change its orbit, making it almost impossible to avoid flying in the sky while running on the road, and the explosion range directly covers 500 kilometers. This high-temperature explosion is enough to wipe out everything.
Zhang Xu is still a carbon-based creature. As long as it is a carbon-based creature, it is afraid of flames and combustion. It's just that evolvers have stronger recovery capabilities and can survive longer.
Combustion is both a chemical phenomenon and a physical phenomenon. Fire is the energy released when material molecules are separated, collided, and combined into low-energy molecules after splitting.
If you want to crack it, other than launching a large number of undifferentiated anti-aircraft missiles, a blind cat will kill a mouse, but this is almost impossible. The rest requires supercomputers to calculate, and their computing power exceeds that of the Dongfeng M-397 ballistic missile. Flying speed, you can easily estimate its flight dynamics.
Many small countries do not have supercomputers at all. It can be said that this Dongfeng M-397 alone makes most people helpless. Although Zhang Xu has Xiaoan, a supercomputer, he does not have anti-aircraft missiles.
The majestic ballistic trajectory is launched with the countdown, and a series of equally spaced circles at the end emits a dazzling light. This is the Mach ring. It is because the gas produces a cycle of expansion and compression when the internal and external pressures are inconsistent, and the hot plasma heat wave seems to Brown everything.
The ballistic missile launches very quickly and flies even faster. It rises resolutely like a shining sun, then disappears from people's eyes and leaps across the atmosphere.
Zhang Xu and the others felt violent vibrations, and suddenly calmed down after just a moment. This is a state that can only occur when entering space.
People know that there is no absolute vacuum in the universe, and there is extremely thin gas in the vacuum. The missile cannot touch a large amount of air, and the friction is almost negligible, so it is extremely stable and flies very fast.
So why don't other countries invent such ballistic missiles? The principle is already known. Isn't it faster?
But although we know the principle, it is extremely difficult to put it into practice. First, when the missile enters space, the wings lose their function and the missile cannot be controlled. It can only fly in a straight line.
This means that they cannot turn in the orbit and then land at the desired destination. This technology is only in the hands of big countries. Even if they get the sample, many people can only watch it and cannot learn to imitate it. This is also One of the reasons why country Z dares to sell.
In order for a missile to maneuver in space, it must place both oxidizer and combustion agent inside the missile body. General missiles do not have built-in oxidizers and most rely on oxygen in the air to work. Therefore, most missiles cannot fly freely in space. flight.
Under vacuum conditions, the missile wings have no effect. To change the missile's flight attitude or direction, a lateral injection device must be installed on the missile.
This requires precise electronic control, because you don't know when the missile will enter space and whether you need this device. You have to rely entirely on the missile's internal missile-borne computer to calculate it alone.
After a very short period of stability, Zhang Xu and the three of them felt a violent vibration again. Yes, they had returned to the atmosphere again.
"Are you ready?" Zhang Xu said in a deep voice in the dark warehouse.
"Yes." The two responded in exactly the same way, and such a straightforward agreement also represented their firm will.
As soon as he finished speaking, the indicator light in the warehouse glowed bright red, like a sunset ruby, indicating that he was ready to land!
