The design team of the OKB-52 Design Bureau—I don’t know if it will be named Rainbow Design Bureau in the future—went to the Central Aero Engine Research Institute with Tang Hua, because OKB-52 led the Eagle Strike-2 and Eagle Strike-3 The task of the anti-ship missile Soviet design team.

The chief designer of the Soviet design team is Vladimir Nikolaevich Chelomi. In fact, he has been working on P-5, P-6 and P-7 heavy anti-ship missiles for the past two years.

Tang Hua: "The second-generation heavy anti-ship missile? Very good."

Chelomi: "Actually, it was split into two schemes. The P-5 is a traditional heavy anti-ship missile, and the P-6 is a nuclear warhead scheme. The P-7 is an improved version of the P-5 with an extended range design. "

"If the P-5 is a redesigned missile with a completely different aerodynamic and power system from the 590, then its range may be too far, beyond the limit of what the Soviet military's current combat system can support." Tang Hua said , "This is the most difficult problem to solve. If the nuclear warhead solution is used for land attack, there is no such problem."

Chelomy: "If your trip to the Soviet Union is not too intense, maybe you can come to Reutov. The P-5, P-6 and P-7 project teams are there."

If the estimates are correct, these three missiles are what NATO calls the SS-N-3 "Saddock".Because the launch tubes of the three types of missiles are common, the Americans regard the three types of missiles as one type.

The successor of SS-N-3 "Sandock" is SS-N-12 "Sandbox", and the successor of SS-N-12 is the famous SS-N-19 "Granite", the legendary aircraft carrier killer.

Tang Hua: "Some problems cannot be solved by the design bureau. Moreover, this kind of missile is not suitable for China."

"China is also facing the oppression of the US Grand Fleet."

Tang Hua: "The problem is, China doesn't have any large warships and large submarines...it won't be for a long time in the future."

"Good morning, Comrade Kononenko," "Good morning, Comrade Svechev."

"First of all, there is good news. The new solid rocket motor completed its flight test in the Black Sea two days ago. The same test in the Bohai Sea is expected to start a week later." Kononenko said.

In the projection hall, the aerial images of the aircraft completely recorded the whole process of a missile from boosting takeoff to cruising flight and finally running out of fuel.

If everything is normal, then this missile should be the test missile of Yingji-2.

"After switching to the new propellant and the new solid rocket motor, all the flight indicators of the missile have improved," said Kononenko. "The original range was 30 kilometers, and the test of the new missile flew 45.5 kilometers in the air. , If the 7% remaining fuel is retained as the standard, the design range of this missile should be 42 kilometers. The flight speed was increased from Mach 0.78 to Mach 0.85, and the missile made three turns according to the procedure during the flight. "

Tang Hua: "The range of the next-generation missile can be significantly improved. But this time we are mainly concerned about the advance research progress of the engine of the next-generation missile."

Svechev, who was in charge of this project, had a bright forehead and scratched his head after hearing what Tang Hua said. "The technical indicators are very demanding. At present, the design of the engine principle model has been completed, and that's all."

On the drawing is a small turbojet engine.With a diameter of more than 300 mm and a length of 600 mm, it is one size smaller than the "small engine" previously considered by the Central Aero Engine Research Institute.Before the YJ-3 pre-research plan was put forward, the Central Aviation Engine Research Institute always felt that the engines used in the P-5 and P-6 were already considered small aero engines.

The P-5 is 11.75 meters long, has a projectile diameter of 0.98 meters, a wingspan of 5.0 meters, and a projectile weighing 5 tons...

Still about the size of a fighter jet.

The engine of the YJ-3 will be changed from a solid propellant rocket engine to a small jet engine.

After all, subsonic anti-ship missiles are still flying at low and ultra-low altitudes. Solid propellants are equivalent to containing fuel and oxidizers. If they do not use the oxygen available everywhere in the air, it is a waste of the weight index of the missiles.

Tang Hua set the design goals for the volume, weight, fuel consumption rate, and thrust of the missile-borne small jet engine, and then told the Central Aviation Engine Research Institute that this kind of engine only needs to work for one hour to complete the job-the engine's full life is one hour. , you figure it out.

"How long will it take from the principle model to the land bench test?" Tang Hua asked.

Chapter 34, T54 launches trade-in campaign

In February 1951, Tang Hua came to the Soviet Union to do a T2 promotion meeting. Three Russian phrases were written on the display board: "Go to communism! Go to the future! Go to T51!"

Then for two years there was either no time to come to the Soviet Union, or not to come in February. Both T2 and T52 were issued by the staff of the embassy in the Soviet Union.

Three years later, Tang Hua came to promote T54.

There was only one sentence written on the display board this time:

"компьютер всех стран,соединяйтесь!"

Chinese means: Computers all over the world, unite (connect) together!

……

Computers all over the world are still not connected.Even the computers in the entire Soviet Union are now difficult to connect.

This time, it is the office LAN solution that is promoted together with T54.

"Human society is developing at an unprecedented speed. Today's human world is called the Cold War era by some, and the nuclear energy era by others. If we use a more approachable term to describe it, perhaps we should say that we have entered the computer age. "

"Data has filled your daily life. Every day you take out coins to ride the bus, the coins are data; when you walk into the office, you are exposed to data; at lunch, how much food is on the plate is data; if you I also ordered a newspaper, so the information in the newspaper is also data.”

"From T50 to T54, computers have become more and more excellent in the fields of data calculation, data processing and data storage. But from today, computers will not only be a tool for data calculation, processing and storage, it will also be used for communication and completely Subvert all means of communication!"

The curtains on the left and right sides of the exhibition board are retracted.Two T54 computers are displayed in front of the audience.Tchaikovsky's "Slavic March" sounded.

Then, one left and one right T54 computer started up one after another, and the marquees on the two cabinets swished and rolled.

...Don't ask why integrated circuits have appeared and still promote T54 in such a fancy way, just ask to make money.

"Since the beginning of human civilization, the development of communication technology can be divided into three stages. The first stage is the stage of physical movement to transmit information. People use walking, riding, boating, carrier pigeons, etc. to transmit macroscopic objects carrying information. The second stage is the stage of electromagnetic wave transmission of information. Morse’s telegraph in 1837, Bell’s telephone in 1875, and Marconi’s wireless telegraph in 1895, they allowed the speed of information transmission to exceed the speed of motion of macroscopic objects, reaching speed of light."

"The third stage begins today. The world enters the stage of transmitting digital information, which is the stage of computer data communication."

USSR, State Planning Commission office building.

"In 1953, China's industrial output value increased by 20.1% over the previous year. Among the major industrial and agricultural products, the output of grain was 1.63 million tons, the output of cotton was 130 million tons, the output of cloth was 38.3 billion meters, the output of steel was 197 million tons, and the output of coal was 7300 million tons. , 77 billion kilowatt-hours of power generation, and 43.6 tons of oil output. Among them, steel production increased by 1952 tons compared with 52."

The Chief Accountant communicated with Maxim Sabrov, Chairman of the State Planning Commission of the USSR, on the implementation of China's First Five-Year Plan in the first year.

"Comrade Deputy Prime Minister," said Sabrov, "I want to make sure that you are using the November statistics to estimate the annual growth rate?"

Chief Accountant: "No, the statistics we use are the complete figures for the 12 months of the year in major central cities. Of course, we may need to check again for complete verification, but the error will not be too large; small cities and Rural is using mid-December statistics to make full-year estimates."

Sabrov: "It was originally planned to discuss the implementation of the First Five-Year Plan with the Chinese side in mid-March, but now it is early February. You came to the Soviet Union and proposed to start discussions, and then gave an almost accurate full report. annual data?"

The chief accountant nodded with certainty.

"How did you do it?"

"In July 1953, our country began to conduct the first national census. From September to October, we built a computer communication line connecting Beijing to five major regions of the country, which was exclusively used by the government for government affairs. When transmitting demographic data At the same time, government affairs data is also transmitted from the five regional cities to the capital, so we get survey data on the national economy faster than before."

Sabrov: "There are computers in the State Planning Commission of the Soviet Union, and there are quite a few of them. I remember that there were more than [-] computers last year. How to make computers use communication lines?"

The chief accountant looked at his watch: "I think at this moment, Tang Hua is explaining how this is done in the academic lecture hall of Moscow University."

……

"There is no doubt that the computing speed of the T54 computer will continue to grow. Its computing speed is 53% faster than that of the T40, and it can handle more heavy data processing and computing services. But data storage and data communication capabilities are the key The greatest revolutionary advance in the T54 computer."

"On the T54 computer, for the first time, we built a new kind of random access memory - the hard disk."

"As we all know, from T50 to T53, these four generations of computers use magnetic core memory, which is an expensive random access memory. Although it can allow the computer system to read data in any part of its storage area at any time, it is expensive and has a large capacity. Small. I believe that if you use computers for government information processing, you will often encounter the problem of insufficient storage capacity, and tape drives have become a very common data backup tool.”
