Chapter 1207 The Wind in Wanhujiao (Third update, please subscribe)
Wanhujiao in the evening has a different kind of beauty. The gentle sea breeze blows from the sea, and the sea, beach, coconut trees and The sunset together forms a beautiful picture.
The most eye-catching thing in this picture is the huge launch tower. This is just one of them. With the development of the aerospace industry, Wanhujiao now has four launch sites, four Launchers of different sizes are lined up along the coastline, which is so spectacular.
On the coastal road leading to the launch site, there is an electric transportation vehicle parked - this type of electric vehicle using sealed lead-acid batteries is very common in Nanyang. Although the range is limited, it is used in the field A transportation vehicle is also very suitable.
Zhang Yuanpeng, who was sitting in the traffic car, first handed a cigarette to his friend, and then just sat there, smoking silently. Occasionally, he would cast his eyes to the No. 2 launch pad in the distance. , where a Wanhu-5 rocket stands. In a few hours, it will send three artificial satellites into space.
After the United States and the Soviet Union, Nanyang will be the third country to realize the "multiple satellites with one arrow" technology.
However, when looking at the rocket, what Zhang Yuanpeng was thinking about was the "Peace Guardian" intercontinental missile. This missile is an intercontinental missile that has just been successfully developed by Nanyang. Its range is 12,000 kilometers. During the development of this When building a missile, in order to improve accuracy, he used a high-performance computer - a computer composed of multiple integrated circuits. Its response time and system performance were qualitatively improved, far superior to those of the U.S. and Soviet intercontinental missile systems at the time.
As an engineer involved in the development of this missile, Zhang Yuanpeng stared at the rocket in the distance and said to himself:
“It is a pity that such technology is not used in missiles!”< br>
“What?”
Wang Ping'an, who was sitting aside, wondered:
"What technology?"
"One arrow has many stars."
Pointing to the rocket in the distance, Zhang Pengyuan said :
"Although our "Peace Guardian" only has a range of 12,000 kilometers, as you know, because of the equator, its payload exceeds one ton. Such a missile only needs to launch a nuclear warhead. What a shame.
Nowadays, the miniaturization of nuclear bombs is going very smoothly. If the one-shot-multi-satellite technology is used, at least four nuclear bombs can be launched to enemy countries. Attack four targets at the same time, or even ten targets! ”
For all the engineers involved in the "Peace Guardian", although they are very aware that the performance of the Peace Guardian is very advanced, but if its performance can be further improved, naturally no one will refuse it. .
"At that time, one of our missiles will be equivalent to several missiles, and only a limited number of intercontinental missiles can destroy a country. ”
When mentioning “destroy a country”, Zhang Pengyuan sounded very calm, as if he was mentioning one thing after another.
This is the characteristic of the era of nuclear war. , war is no longer about winning or losing the war, but about destroying the enemy country and using destruction as a means.
It was under the deterrence of such nuclear weapons that the world truly entered a peaceful era. After all, before this, the purpose of war was based on victory.
Now, in the era of nuclear weapons, the purpose of war has changed. , turned into destruction, taking destruction as the ultimate goal of war.
So, for Zhang Pengyuan, the question he needs to think about is how to maximize the power of the "Peace Guardian" intercontinental missile, so that he can more easily complete his design mission-to remove enemy countries from Wiped off the earth.
"Your idea is very normal. We have been studying this since the Americans used the last stage of the "Thor-Able" launch vehicle to send three satellites into low-Earth orbit last year. The Americans are high-profile The reason for promoting this is to tell the Soviets that they can launch several nuclear bombs at once. "
This is the truest aspect of the Cold War. The core of the so-called "space exploration" is to serve the war. However, everyone puts on the cloak of "for peace" and "for all mankind". To put it bluntly, it is just to sound good, but deep down they want to destroy them!
Of course, nice words always need to be said, but those words are meant for outsiders.
Wang Pingan said.
“But don’t forget, accuracy, “one arrow, multiple stars” is to put it bluntly, it is clustered multiple warhead technology. Just spread the warheads like salt in the target area, but the problem is What about the accuracy? "
Turning to look at Zhang Pengyuan, Wang Ping'an said:
"Don't forget, when we were developing the "Peace Guardian", we found that we could double the missile's strike accuracy. This means that to destroy the same target, the yield of the warhead required can be reduced to 1/4 of the original.
When the hit accuracy remains unchanged, if the warhead power is doubled, the destruction capability will increase by about 0.6 times. If the warhead power remains unchanged and the hit accuracy is doubled, the destruction capability will increase by about 3 times.
In short, improving the strike accuracy is much better than increasing the power of the warhead. Therefore, we spend so much energy to solve its accuracy problem. "
As soon as Wang Ping'an finished speaking, Zhang Pengyuan asked.
"How to solve the accuracy problem? ”
“Computer! Improving strike accuracy depends largely on the performance of missile-borne computers and gyroscopes. ”
"Yes, it is a computer. In fact, without a powerful missile-borne computer, it is impossible to realize multiple warheads with separate guidance."
Zhang Pengyuan said and explained:
" At present, our computer and guidance system cannot meet the needs of a separately guided warhead. The main reason is that its performance cannot meet the requirements of rapid trajectory calculation. After the CPU calculates the trajectory, the warhead has already missed the window. "< br>
"This is why they have to complete calculations on the ground, and then release the satellites one after another. Satellites can be launched in this way, but missiles cannot. When we were developing the "Peace Guardian", a technical indicator, That is, the guidance system does not rely on any information outside the missile. In this way, a real nuclear counterattack can be carried out under the conditions of nuclear war. "
In fact, the Wanhu 5 rocket has never been qualified. Strategic missile, because it relies not only on the observation of the position of stars or land, but also on radio or radar signals, which means that if the command center or the measurement and control ship is destroyed, it will become blind.
However, the inertial guidance system of the "Peace Guardian" does not rely on this external information, thus truly achieving launch and forget. "In other words, without a powerful computer, one arrow with multiple bombs is actually just a cluster bomb. When it reaches the target and releases the warhead, the effect is not much different from one."
Listening to Wang Ping'an's analysis, Zhang Pengyuan pursed his lips and said:
"Then we will develop a more powerful computer. As long as this problem is solved, the remaining problems will not be a problem. !”
When Zhang Pengyuan said these words, his eyes were staring at the Wanhu Type 5 rocket, filled with some kind of desire. There was only one question on his mind - how. Protect the safety of Nanyang as much as possible!
An hour later, facing the afterglow of the setting sun, the Wanhu Type 5 rocket was successfully launched again, and once again successfully sent a satellite into space.
Although Nanyang has launched the fewest rockets in the past few years, and did not even launch its first lunar probe until the end of last year, Nanyang has been steadily advancing its rockets step by step. Plan and develop towards a long-term goal bit by bit.
Moon!
There is a picture of the moon hanging in Qian Fukang's office. It was a picture of the moon taken by the "Yutu 1". This picture represents a certain vision - the moon landing.
However, among Qian Fukang's current work, developing moon landing rockets is not the most important. The most important thing is missiles.
"Solid motor!"
Pointing to the drawings on the drawing board, Qian Fukang said:
"The military's requirements are very simple. They require that submarine-launched missiles must use solid motors."
In fact, no one in Nanyang knows submarine-launched missiles better than Qian Fukang. The plan for Nanyang’s first-generation boat-borne ballistic missile was to slightly modify the “Wanhu Type 4” medium-range missile that uses liquid propulsion on land. It is then equipped on the ship to form a shipborne weapon system.
Qian Fukang, who had just arrived in Nanyang at that time, made compromises and changes to the "Wanhu Type 4" missile from the original 29 meters long and 2.41 meters in diameter to 17.7 meters long and 2.67 meters in diameter. However, it has the same problem as the "Wanhu Type 4", that is, deploying liquid propellant missiles as a strategic missile system has many problems and difficulties in logistics, safety, launch and combat.
In addition, the ship-based "Wanhu Type 4" missile can only be temporarily filled with liquid propellant before launch, which takes a long time and is very complicated; when the missile is launched from a submarine, the acceleration of the missile when taking off is low, which may cause serious problems and consequences. . Therefore, the modified missile cannot meet the requirements of simplicity, reliability, and rapid and timely launch expected by the Navy.
But even so, the naval technical department still used it to conduct a large number of experiments, and finally successfully achieved underwater launch, but this did not solve the problem of its launch complexity.
So the development of new submarine-launched missiles has become a top priority, especially since the Navy has included ballistic missile nuclear submarines in the plan.
“But if a solid engine is used, the range may not be able to meet the Navy’s demand for range. The thrust of the solid engine is small. Even the American Polaris has a launch weight of only 12 tons and a range of only more than 2,000 kilometers. "
As the most authoritative rocket engineer in Nanyang, Eugene Gesang is very clear about the performance advantages and disadvantages of liquid rocket engines and solid rocket engines. The former can easily become bigger and stronger, but the latter But it's impossible.
"Let's take it step by step. According to the requirements of the Navy, the missile length cannot exceed 10 meters. This means that if we want to increase the range, we can only make a fuss about the diameter of the missile and the material of the missile body. The first is to reduce the weight of the missile body as much as possible. , I already have a plan for this, that is, the shell of the second-stage rocket is made of glass fiber, and the second is to increase the width of the projectile appropriately..."
After introducing his ideas one by one, Qian Fu Kang turned his attention to Eugene and said:
“But the most critical thing is the solid rocket motor,”
Facing Qian Fukang’s gaze, Eugene thought for a while and replied .
“Now our 15t-class solid rocket is under development, and the technical problems have basically been solved. If everything goes well, we will probably be able to produce samples in the middle of the year.”
Eugene's answer made Qian Fukang fall into thinking. He silently took out a cigarette and smoked it for a while, then said:
"15 tons is still a bit too small. The maximum range of this range is only 3000km. We are still far away from the Navy's requirements. Can we think of another way? Even a few hundred kilograms would be good. After all, for missiles, even a distance of one or two hundred kilometers is very important."< br>
Regarding this request, Eugene shrugged helplessly and said:
“There is really no way to do this, at least until the high-performance propellant is successfully developed, there is no way. For now, you can only make a fuss about missiles. ”
What kind of fuss can you make about missiles?
Of course, we need to further optimize the missile body design, and use new materials. Of course, it is also possible to design a self-guiding system that weighs less.
Although there are many solutions, none of them are easy to solve. Therefore, for Qian Fukang, there are many problems that need to be solved next.
"The best way is to increase the length of the missile..."
Despite what he said, Qian Fukang knew that this was impossible. After all, ballistic missiles now Nuclear submarines are being manufactured, and the size of the missile is limited by the size of the submarine.
“It’s really a pity...”
