Chapter 357 Beautiful and Dangerous
.
Although the split missile warhead reduces the power of a single warhead. However, for Ding Yiqian, this is also a rare solution for China. Moreover, although the split warhead is destined to be much smaller in size than the single warhead, don’t forget that there are hydrogen bombs. According to the scheduled plan, in one or two months, the world’s first hydrogen bomb will be tested. It has the same design and production concept as the development and production process of the atomic bomb. The first batch of hydrogen bombs were not produced in a single batch, but about three were produced in the first batch, and then gradually accelerated its production speed.
After visiting the rocket assembly workshop, Duan Guoxue and his group also visited the component assembly workshop. Here, the best parts developed and produced by many factories across the country are assembled into components one by one and then transported to the assembly workshop not far away. These parts are specially produced parts. These parts are more stringent than traditional military products, because in a working environment like a launch vehicle with high overload, large vibration and huge temperature difference, any product quality deficiency and negligence will cause unimaginable heavy consequences. Duan Guoxue still remembers that in the later
In the competition between the world, the United States and the Soviet Union, the Soviets relaxed the production quality of the rocket engine in order to save money on the rocket engine. As a result, the rocket exploded directly on the launch frame. Thousands of tons of rocket fuel was a bomb of thousands of tons. The power of the explosion tore the launch center into pieces. The explosion not only destroyed the rocket that the Soviets landed on the moon, but also destroyed the launch platform that took ten years to build. It was because of this that the Soviets took a big detour in rebuilding the launch center and waited for a long time in vain.
With Zhang Deyi's explanation, Duan Guoxue also visited the special fuel supply station 30 minutes away from the Rocket Launch Center.
The spectacular scene of the rocket ignition and flying is dazzling and exciting, but what force makes the huge rocket hold the spaceship and satellites travel in space? The answer is the "blood" of the propellant Rocket. As the most important part of the rocket, the production of rocket propellant is not an easy but comfortable and romantic thing. Here, accompanying the toxicity and danger is a true portrayal of this.
In the special fuel supply station of the rocket, you can see light blue liquid oxygen, colorless and transparent liquid nitrogen, and the liquid hydrogen that seems stable but is actually extremely dangerous. Everything in front of you looks beautiful and beautiful, which makes people feel suffocated. However, they do not know that the rocket propellant is a highly drug and extremely dangerous product. In the special fuel supply station where there is no one living in a radius of five kilometers, there are only staff who are transported here from outside every day, in order to reduce the secondary damage caused by the accident as much as possible once a production safety accident occurs. Therefore, the special fuel supply station of the special fuel supply station is free of charge.
The station appears lonely, and in the special-gas station, you can see slogans like "Serious and meticulous, foolproof." The red slogans appear very dazzling here, in order to remind people working here to be cautious and cautious at any time and anywhere, be careful about the work at hand, and be careful about the site at hand. This is not the site that Zhang Deyi is responsible for. The person in charge here is Qu Shuwen. Under his introduction, the propellant required for the entire process from rocket ignition to satellite space flight, as well as orbit change and landing in normal times, is provided here.
Duan Guoxue and his group walked into the "blood" manufacturing workshop of more than 1,000 square meters of rockets. The scene in front of them was difficult for visitors to associate it with the romance of "Flying Sky". The machines roared, the instruments jumped, and equipment of different sizes and shapes were connected by pipes of different thicknesses, which made people feel suffocated. Chief engineer Chen Jianping pointed to a steel pipe extending outside the factory wall and said to the visitors:
"This walks through the air inlet, it sucks the air in. After compression, separation, purification and other processes, it finally enters a tall low-temperature separation tower. After cooling and liquefaction, liquid nitrogen is obtained at the top of the tower and at the bottom of the tower. In this way, after a series of treatments, the ordinary air entering from the air inlet magically turns into light blue liquid oxygen and colorless and transparent liquid nitrogen in the fractionation tower. In another production workshop today, a large amount of fresh water is there to generate oxygen and hydrogen by electrolyzing water, and then converted from equipment to liquid oxygen and liquid hydrogen.
Everything that appears before the visitors looks beautiful, but they don’t know that rocket propellants are highly drugs. Working here is called “a dance on the cliff. Since the site was established, the officers and soldiers working here have been working hard for more than ten days, silently making contributions to provide tens of thousands of tons of high-quality “blood” for satellites, rockets and other scientific research and testing tasks launched by China.
In the workshop, staff wore anti-static clothing and kept checking various facilities and equipment. Deputy stationmaster Zhangrui introduced to everyone: The freezing point of liquid oxygen is 18 degrees Celsius, and the boiling point is 180 degrees Celsius. As long as it is higher than this temperature, a high concentration of oxygen can be formed. If there is an electrostatic spark similar to wearing and taking off clothes, it can cause an explosion.
Hearing this, all the visitors couldn't help but feel a little nervous. After that, they were careful when walking every step in the workshop, lifting up and lowering each step, for fear that they would give their lives here with one step. Although the short visit was not long, after coming out from here, everyone's back felt wet. Everyone felt huge mental pressure in this short time, but look at the officers and soldiers who were still at work, they had to work here every day, and the production of rocket propellants had been
It is very dangerous, but what is even more dangerous is to escort these rocket propellants. The work of escort rocket propellants is like sitting on a crater. Once a spark is encountered, it will cause violent explosions. Pedestrians come to the propellant storage and transportation area of the special-fuel station, and a faint fishy smell hits the face. Huang Haihua and Liu Junpeng, the non-commissioned officers in protective clothing, are carrying out propellant transfer operations. When the accompanying reporter was about to step forward to take their work photos, they were immediately pulled five meters away by the accompanying staff because the propellant emitting this fishy smell was highly toxic.
Warehouse Director Zhao Guangrui said: It is difficult to carry propellants and has great risks. It is like sitting on a "crater". Once you encounter a spark, it will cause a violent explosion. Every time you escort, the leader of the special-gas station leads, and Director Zhao of the warehouse himself has escorted four times. At present, there are still six groups of personnel performing escort tasks outside.
The visitors then had a discussion with the escort veterans and listened to many of their little-known stories.
Before a rocket was launched, these veterans transported propellant to Jiuquan Wei Er, and the refrigeration compressor suddenly stopped rotating on the road. This made the escort:, 2 nervous: If the temperature of the propellant transported in the car rises too high, it will gasify, and then cause an accident, and the consequences will be unimaginable. After two days and nights of continuous inspections of all lines and contacts, the fault was finally found: due to the turbulent train running, the escort team members hugged each other tightly. This was not the cry of joy when the soldiers struggled back from the brink of death, but it could ensure that the rocket launch mission was completed on time. For this pound and target, the soldiers who were transported had already put their life and death aside.
During another escort mission, the escort propellant arrived at the Xichang Satellite Launch Center. On the way, the escort team members conducted routine inspections and found that the propellant leaked out of the sampling tube. Once sparks were encountered, it would cause a violent explosion. Other treatment measures were too late. Team member Xu Zhiming immediately put on rubber gloves to tightly block the leakage, and the leakage stopped. Then, he asked his comrades to tie his hands tightly to the sampling tube and persisted in the pungent carriage until the destination.
As soon as he got off the car, he was admitted to the hospital for a full half year.
What makes these escort officers and soldiers most uncomfortable is the loneliness of long-distance escort. Since the escort is extremely dangerous explosives and highly drugs, the vehicles along the way will avoid the living area as much as possible. In order to avoid major casualties and construction damage, most vehicles are secretly escorted at night. This stop-and-go will inevitably extend the delivery time.
Sometimes these escort officers and soldiers left for more than three months, and the magazines they brought were broken, and the newspapers and magazines could be memorized. However, no matter how long the parking time was, no one could leave the station. Facing the bustling city that the convoy passed by, famous mountains, these escort officers and soldiers could only "look at the sight and sigh that there was once, when the escort propellant special train passed through Ganqi Tanjiajing Station, the 4-month-old wife of the non-commissioned officer in Kangzhou rushed from home to the station, waiting for the arrival of peanuts and sweet potatoes in her hands. However, in order to stagger the passage time of other trains, the special train stayed for a short time. His wife and mother Caiwang met Kangpa and said goodbye with tears.
"Although I'm unknown, I feel it's pretty when I see the rockets take off." The escort veteran Kangzhou shyly told these senior Chinese leaders about his true feelings in his heart.
Next to the propellant storage warehouse, a glass column equipment attracted many people's attention. Under the introduction of the warehouse manager, everyone knew that although its structure was not complicated, it could solve a very big problem.
This is a device composed of twelve glass columns with a diameter of 50 mm and a height of 4 meters. When Li Delin curiously asked about its name and purpose, Lei Jianjun, a senior engineer at the special fuel station, proudly said: "This is called the "Ding-like propellant photolysis purification device""
Because among liquid rocket propellants, the more commonly used ones are nitrous tetraoxide stress dimethyl hydrazine, methyl pong, pong, liquid ammonia oil, liquid hydrogen and liquid oxygen, etc. The specific impulse value of hydrazine fuel is very good. Although propellants and combustion products are highly toxic, they are highly reliable. Even in later generations, they are mostly used in the first generation of strategic missiles and aerospace launch vehicles. However, hydrazine propellants are very likely to turn yellow during storage and transportation. The common method in later generations is to abandon or return to the factory to deal with it, causing a great waste of manpower, financial resources and time. After years of research, Li Peng, the former head of the special gas station, found an effective solution.
On this basis, Lei Jianjun and his colleagues solved several problems and developed this device that can handle ten tons of yellowed and deteriorated corpus propellants every day, saving a lot of valuable funds for the country.
The research and facilities won the first and second prizes of the military's scientific and technological progress respectively.
However, today's launch vehicles are still very traditional liquid propellants, but one of the negative effects of liquid propellants is that they need to inject fuel from the rocket propellers before each launch. This process takes one to three hours. In the army, such a long time will inevitably cause delays in fighter jets. Therefore, as a more advanced solid rocket, it has become the first choice for the army's future missiles. Only solid fuel launch vehicles can be launched at any time, fast, accurate, and fully integrated attacks. Remember that half a year ago, a modified upgraded submarine launched a missile with a range of 4,000 kilometers from the South China Sea to the center of Jiuquan satellite on the sea surface? It is inseparable that such a long range is closely related to these people.
The reason why Duan Guoxue made great efforts to put the shellless bullets in advance was that he needed to use the plasticized rubber base project in the chemical industry to drag China's overall chemical industry. There is a saying that goes.
If the machinery industry is the father of modern industry, then the chemical industry is to support the mother of the development of modern industry. Whether it is the use of chemical methods to reduce impurities in steel or the most intuitive production and development of chemical industrial products such as plastics and nylon, the lag of the chemical industry will inevitably drag down the development of other industries.
In later generations, China's first generation submarine-launched missile, Gioro-Roy 1, had a range of only 2,000 kilometers. This number is very short and helpless, because the entire Chinese chemical industry started late at that time, and the lag of chemical products dragged down the growth of rocket range. However, after entering the reform and opening up, China's current production industries have greatly improved, and the chemical industry has also achieved corresponding long-term development. The range of the second generation Gioro-Roy 2 missile has increased by four times to 8,000 kilometers. According to the rumors, the improved range of the Gioro-Roy 2 missile will be as high as tens of thousands of kilometers, but here
In space and time, Duan Guoxue used the prophet's strategy to prioritize the development of a number of industrial systems and key educational systems. The results of the development of a number of industrial systems and key educational systems were revealed twenty years later. At the same time, it was able to produce plasticized rubber-based products that only Chinese people in the world could produce, which greatly improved the production level of China's chemical industry. The missile launched by the submarine that time was still named the Julang missile, but the range of this missile was definitely not the short foot in later generations, but reached a thousand kilometers with the perfect performance of the specially made special propulsion fuel developed in a special factory workshop.
Although the production of special supplies will certainly not be large, the missiles carried by these submarines are enough for these few missiles to be used,
