Back to the Republic of China to be a editor

……

In the Bureau of Electronics and Information Industry, Tang Hua saw the telegram sent by Lu Xiaopeng from Moscow last week, the wind test report of Model 1.

The report was indeed very long, and after it was transcribed into small print, there were more than ten pages.After reading through the report, I found that the test went well. Lu Gong hardly modified the aerodynamic shape of the model. When he arrived at the Mikoyan Design Bureau, he did the wind tunnel test step by step, and completed the wind tunnel process node by node on time. Then send a telegram.

There are actually many test items. At several typical speeds, the lift conditions of the missile model at different angles of attack should be tested separately. This determines how the missile should fly after it is launched, so that the angle of attack of the missile body can just produce a suitable lift.Then, at several typical speeds, the aerodynamic rudder surface of the missile in the wind tunnel was deflected one by one, and the steering moment generated by the missile rudder surface at a certain deflection angle was recorded.This is related to the control signal of the missile. The value of the rudder steering command output by the computer depends on this set of original parameters.

After reading the wind tunnel test report, Tang Hua immediately sorted out the parameters related to the vector calculation output, and asked Secretary Wu to take it to the computer development team of Liumei Institute.Looking at the time, several comrades from the Aeronautical Engineering Research Office of the East China Military Region should have arrived at the laboratory. Tang Hua also went downstairs to get in the car and walked to the laboratory in the western suburbs.

"Hello, Director Huang." Entering the laboratory, Tang Hua first noticed the highly recognizable square face. This should be Director Huang Zhiqian of the Aeronautical Engineering Research Office of the East China Military Region.

"Hello, Minister Tang!" Huang Zhiqian and the comrades in the Sanming Research Office also noticed Tang Hua walking towards them.

A pair of thick glasses, a square face with a bit of baby fat, and a hairline that has moved up by at least two inches at the age of 36. What does this mean? It means that this brain is extremely smart.

In 37, he graduated from the Department of Mechanical Engineering of Shanghai Jiaotong University with a major in aviation. He first repaired aircraft in the National Air Force. Development of P.45 jet fighter demonstrator. At the beginning of 46, seeing the situation on the battlefield of the Civil War reversed, Lao Huang began to teach himself Russian. At the beginning of 228, he decided to return to China. Without the assistance of China Resources, he took six boxes of materials by boat, changed ships twice through Hong Kong and Incheon, and returned to Tianjin.

It's all right now. In the future, the chief designer of the Qiang-5 and the first chief designer of the J-8 will now all be found by Tang Hua to engage in missiles.

"Director Huang, comrades in the research office," Tang Hua said, "Our Aviation Industry Bureau is still in the preparatory stage, and the construction of the aviation industry system may take a while. But now the Electronic Information Industry Bureau and the Ordnance Industry Bureau There is an equipment development project that needs experts familiar with aviation technology and flight control, so I temporarily transferred you here. This project is actually related to aircraft, but it is not an aircraft, but a weapon specially designed to shoot down aircraft."

Tang Hua walked to the other side of the laboratory and took off the canvas covering a large device there.

A GAZ AAA truck loaded with strange equipment appeared in front of everyone.

"This is a vehicle-mounted low-altitude and short-range anti-aircraft missile. The missile is a 'guided rocket'. Your research laboratory is in East China. You should have read the report on the Air Control-1 guided bomb, which means guidance. This This kind of missile has a maximum range of 8.5 kilometers and a maximum shooting height of 4500 meters. It adopts radar tracking and radio command guidance, and the single-shot hit probability is 75%. Now any aircraft equipped by various countries, as long as it appears within the shooting range of this air defense missile, basically There is no possibility of escape."

After Tang Hua finished speaking, Huang Zhiqian and the other three didn't speak at all, they all opened their mouths wide and looked at Gas AAA.

The rear of the truck has been refitted by Jianxin Company, and a slewing tower is installed on the trailer, which can rotate 360 ​​degrees and pitch from 0 to 85 degrees.The launch tower has four launching guide rails, and the guide rails have installed 4 anti-aircraft missiles (wooden models).The revolving launch tower is at an elevation angle of 30 degrees, and the four missiles are pointed at the sky outside the laboratory vehicle shed.The missile model is painted with gray to gray-black paint, with a sharp warhead, a cylindrical body, 4 X-shaped aerodynamic rudder surfaces at the head, and 4 larger X-shaped stable rudder surfaces at the tail.It is full of suffocating modern industrial precision beauty, but also has the murderousness and majesty of weapons and equipment.

"...Minister Tang, is this developed by our country? Didn't the Soviet Union aid us?" Huang Zhiqian asked Tang Hua after recovering from the suffocation caused by the missile.

"Of course we developed it by ourselves, otherwise I wouldn't have called you to participate in the project. Of course, the trucks were purchased from the Soviet Union. After all, we can't produce our own cars yet." Tang Hua patted the base of the launch tower, " This is produced by Dalian Jianxin Company, the radar and control vehicle over there are also refitted in Dalian, and the radar is being refitted by Shanghai. The missile is actually still a model bomb, and the real live ammunition needs your help to make it.”

Huang Zhiqian spread out materials and drawings on a small table in the laboratory. "Oh, rocket engine propulsion. Soviet PR2. Technology transfer has been agreed... 40 engines for comparative tests and preliminary tests. X-shaped aerodynamic control surface at the nose of the missile. The radio receiving antenna is on the tail and body...Don Minister, is the radio signal to control the missile given by the missile controller? Where is the missile controller?"

"The control signal of the missile is obtained by calculating the velocity vector by the computer on the radar and the control vehicle. There is no missile controller, only the radar controller."

Huang Zhiqian looked at the blueprint, then looked up at GAZ AAA, "What should we do if all 4 missiles are fired?"

"The smallest unit of the air defense missile system includes 5 vehicles, a radar and control vehicle, two launch vehicles, and two loading vehicles, each carrying 8 spare bombs. The loading vehicle has also produced a prototype, so you don't need to worry about it." Tang Hua said, "The aerodynamic shape of the missile was tested in a wind tunnel by the Mikoyan Design Bureau of the Soviet Union. There is no problem with the aerodynamics. Your job is to design the internal parts and structures of the missile. The aerodynamics remain unchanged. The weight, mass and center of mass of the warhead Keep within the required range, and then design the basic control function of the missile, achieve the maneuverability index, and the radio transceiver function."

……

Under the leadership of Huang Zhiqian, the team formed by the research office devoted itself to the design work.According to the schedule formulated by Tang Hua, after the design is basically completed, they will be sent to Dalian together with the design results, where parts will be produced and the first batch of anti-aircraft missile samples will be assembled.Then, take the sample bomb back to Beijing's missile test site for test firing.

The first batch of sample bombs were tested for uncontrolled flight, that is, they were shot out as a rocket.

The second batch of sample bombs was tested for self-control bombs.

The third batch of sample bombs is used for remote control testing to see if the radio command system can work normally.

In the fourth stage, fixed floating balloons will be played.

In the final stage, the Tu-2 must tow the target drone to do live ammunition shooting.

It is hoped that the construction of the missile test site of the Ming Tombs can be completed quickly, preferably within two months.Today, Huang Zhiqian and the other 3 members of the design team are full of enthusiasm. Maybe the first batch of sample bombs will be produced in advance by them. When the sample bombs come out and the test site is not completed, the progress is blocked by this small problem. That would be too bad.

Mikoyan Design Bureau.

"What is this? Another big rocket?"

Director Mihai of the wind tunnel management department watched Lu Xiaopeng push a long and large wooden model in and asked curiously.

Director Mihai had dealt with Lu Xiaopeng for more than half a month before. When the No. 300 model was being tested, Lu Xiaopeng came every day, and when he came, he occupied a wind tunnel for most of the day.The first two days were dominated by a wind tunnel with a speed of 3 kilometers per hour, followed by a wind tunnel with a speed of 600 kilometers per hour for three days, and then wind tunnels with a speed of 900 kilometers per hour and 1300 kilometers per hour respectively.Lu Xiaopeng also expressed regret, saying that it would be nice to have a wind tunnel with twice the speed of sound, but unfortunately, now we can only use the value of the 1300 km/h wind tunnel as the basis, and then use the equation to calculate the aerodynamic parameters of twice the speed of sound.

"Yes, a big rocket," Lu Xiaopeng told Director Mihai through an interpreter, "Davarish, this big rocket only needs to do 300, 600 and 900 wind tunnel tests, which is a little easier. , 300, and 600 each have two rounds of tests."

Lu Xiaopeng walked to the side of the wooden model, and with a little force, the wooden model was divided into two pieces.

This is a long cylinder with a round head, and three sets of X-shaped airfoils are set on it, and the sizes are not the same.The X-shaped airfoil at the front of the cylinder is the largest, the X-shaped airfoil near the tail of the cylinder is the smallest, and the X-shaped airfoil at the very tail of the cylinder is of medium size.After Lu Xiaopeng separated the wooden model, the X-shaped airfoil and a small section of cylinder at the end were separated.

"This... booster, this bullet, in the overall state of the booster and the state after the booster has fallen off, each test should be done in one round."

Chapter 58, the password head went to Shanghai

"Since the founding of New China, the great cause of unifying the country is entering the final stage. We have liberated most of the country except Taiwan and Tibet. However, the surrounding area of ​​China is not peaceful. The wars in Korea and Vietnam are ongoing. The United States is not only China provoked wars around China and at the same time invaded the Taiwan Strait to prevent us from liberating Taiwan....The founding of New China has provided a relatively stable environment for the development of our national defense technology and weaponry, and it is possible to accelerate the modernization of national defense and the military.”

……

"First, adhere to the principle of independence, self-reliance, and foreign aid as a supplement. China has a population of 5 million. If it cannot produce most of the weapons used by the army, but has to rely on imports, this is unacceptable. In the next few years In [-], rapidly advancing the country's industrialization, establishing a relatively complete industrial system, and building a relatively complete military industry on this basis should be the main tasks of my country's heavy industry sector."

"[-]. Immediately start to improve the production and development system of tactical weapons, and at the same time formulate a long-term plan for the development and equipment of strategic weapons. Strategic weapons, that is, nuclear weapons and equipment that can transport and release nuclear weapons remotely, such as the combination of nuclear weapons and ballistic missiles, nuclear weapons and heavy-duty weapons The combination of bombers and other forms. Tactical weapons are the sum of non-nuclear weapons used in conventional wars and conflicts, and they are also the main body of military equipment in various countries."

"Third, pay attention to the systematization, standardization, serialization, and generalization of weaponry and equipment. We should not look at a certain piece of weaponry and equipment from an isolated and fragmented point of view, but put it in the equipment system of the entire army, and think about its ability to Can it maximize its own combat capability? Can it enhance the overall combat effectiveness of the troops? Can this kind of equipment form a series of equipment and continuously improve its combat capability? One weapon can meet the equipment needs of two or more military branches at the same time? It is suggested to set up an equipment planning bureau under the leadership of the Ministry of National Defense to review and discuss the weapons and equipment to be approved.”

"Fourth, establish a research system for cutting-edge defense technology and equipment. In general, the weapons, equipment, and scientific and technological level of Western countries are currently ahead of ours, but there are exceptions. The use of guided bombs in the Penghu Battle and the export of domestic electronic computers to the Soviet Union are all It proves that under certain special conditions, China's single technology and equipment can be ahead of other countries in the world. In the hands of a powerful army, under proper tactics and command, China's cutting-edge equipment can be ahead of its opponents. To maximize the effectiveness on the battlefield, to a certain extent, enable us to gain an advantage on the battlefield. In order to carry out the planning and research and development of such cutting-edge equipment, it is recommended to set up a secret, dedicated to research, outside the Equipment Planning Bureau of the Ministry of National Defense. An organization with cutting-edge and forward-looking technology and equipment, from a top-level perspective, plans and develops next-generation weapons and equipment that can change the battlefield situation."

After writing the proposal to the Prime Minister (and forwarded to the Chairman and Commander-in-Chief), Tang Hua breathed a sigh of relief and asked the confidential secretary to stamp it out.

It is now September 1950.On the Soviet side, the order for the second batch of T9 computers has been counted, which is more than last month, 50 sets, and more than 20 million rubles.This is probably because Moscow University was among the first customers, who bought a computer that then caused a stir in academic circles throughout Moscow and the Soviet Union.

There were still four months left in 1950. According to this momentum, if estimated optimistically, 50 T1950 computers could be sold in 100, which was more than 5000 million rubles and more than 1000 million US dollars.

It took more than two months for the chairman to visit the Soviet Union, and the result was a loan of 3 million US dollars with an annual interest rate of 1%, 3000 million US dollars per year.If 100 T50 and T51 computers can be sold to the Soviet Union every year, it is equivalent to the newly established new China, and the annual disposable foreign exchange has increased by 1/3.Coupled with the extra money that China Resources took from the pockets of the imperialists, it should be said that the construction project can be accelerated a lot.

"Minister Li," Tang Hua was about to call Li Kenong in the office, "the research and development of the supercomputer and the code-breaking system have been completed, and I think we can organize a team of code-breaking to conduct a trial run. I mentioned it to you last time, didn't I?" Let Comrade Wang Yongjun lead the deciphering team..."

"Oh, Section Chief Wang has already gone to Shanghai with the letter of introduction. Calculating the time, he should have arrived at the Shanghai Institute of Computer Science."

Tang Hua's hand holding the phone froze in the air.Um?Is it too self-conscious?

The life experiences of Wang Yongjun and Grandpa Erlei are similar. He first worked as a radio operator in the national army. He was captured in a battle in 1933 and joined the Red Army. He became an instructor of the team's report training class, and then specialized in deciphering the enemy's codes.During the period of the Red Army, he had conquered about 60 kinds of ciphers in total, including about 30 kinds of ordinary ciphers, 25 kinds of intermediate ciphers, and 5 kinds of high-level ciphers... The ciphers used by the enemy troops around the Hunan-Jiangxi Soviet area were basically all by him. broken.After the Long March arrived in northern Shaanxi, Wang Yongjun began to study it in the autumn of 1938. After a year of hard work, he broke the new codebook used by the Zhongtong. In 1941, the password for attacking the military system was broken at the end of 1941.Since then, Wang Yongjun has been called the "crypto head" in the party.

"In that case, I'm going to go to Shanghai too." Tang Hua said.

North Korea.

After the August offensive, the situation for the People's Army was already very serious.The enemy's solid defense is in front, and the elite of the People's Army has been exhausted, and the logistics cannot keep up. Although 30 migrant workers have been mobilized to transport, the supply line is too long. Started short, even started eating only one meal a day.There are even more terrifying things that the People's Army has not grasped due to insufficient intelligence capabilities: the reinforcements of the US military continue to strengthen.As of September 9, the ratio of troops between the two sides was 1:98000. Although the People's Army is still besieging the Pusan ​​defensive circle, the enemy forces in the defense circle are almost twice that of the People's Army. The army was flat.
