Tang Hua talked a lot about the fire control system. In fact, the fire control computer and the matching sighting system have not been tested on any tank in China.

In today's terminology, it is called "White Wolf with Empty Gloves".

Even the few pages of information handed to Admiral Poluboyarov were a very brief summary of the future development of the fire control system.

This is also because the Soviet comrades suddenly threw out a spy blueprint of the M47 tank, and advanced the matter of the fire control system. Originally, they only planned to mention the matter of the tank fire control computer, so that the Soviet army felt that this direction was very promising. , Aroused their interest in developing a new generation of fire control systems.

In this negotiation at the beginning of 1954, Tang Hua's big cake for Poluboyarov did achieve some results.Poluboyarov said that the tanks being developed by the Soviet Union will be equipped with bi-stabilization, and then Tang Hua said that the imitation model scheduled for the tank factory under construction in Changchun is T-54A, without bi-stabilization.It would not be cost-effective for China and the Soviet Union to develop a version of the fire control system each.

However, the Soviet Union considered that the output of T-54B would be large, and it also planned to develop further improved models. It believed that T-54B must be equipped with a fire control computer.

T-54B之后就是T-55——或者说T-55其实就是T-54B加了三防系统。这不是重点。唐华说的话其实在暗示能不能让给长春厂T-54B的图纸而不是T54A，但这事儿波卢博亚罗夫做不了主，得国防委员会拍板。

In the end, the temptation to earn foreign exchange overwhelmed other factors. The Chinese side and the Soviet side initially agreed to develop a fire control computer that could match the bistable system at the end of 1954, but from the middle of 1954, Lower Tagil would work closely with Changchun to get it done. The linkage between the fire control computer, the sighting system and the artillery system.

"It is necessary for the Soviet Union to remind us about the construction of China's aviation industry and the introduction of models."

Artyom Ivanovich Mikoyan, younger brother of member Mikoyan of the Presidium of the CPSU and chief designer of the Mikoyan Design Bureau, discussed with the Chinese delegation the introduction of fighter jets.

"Whether it is the MiG-15 or the MiG-15bis fighter, it is already behind. Even if the trial production is successful, it will be behind the times and it will be difficult to meet the needs of China's air defense operations. In July 1951, we discussed the fighter project with you When it was introduced, the MiG-7bis was still the most advanced fighter, so you set the target of imitation on the MiG-15bis, but not now. It is already 15, you should introduce and imitate the MiG -1954."

唐华：“沈阳的松陵机械厂（112A厂）最近两年的主要工作都是大修米格-15和米格-15比斯，当然新建的飞机总装厂、零件制造厂等等都只限于制造米格-15比斯。仿制生产米格-17需要对生产流程和工艺图纸做若干调整，因此这事的关键是你方能提供多大程度的帮助。”

Mikoyan: "Before your delegation came to the Soviet Union, I exchanged opinions with the Ministry of Aviation Industry, and the Ministry of Aviation Industry agreed in principle. After the approval of the Ministry of Aviation Industry and the National Defense Committee, we can make a copy of the full set of MiG-17 drawings. It will be provided to Shenyang soon."

Tang Hua: "Comrade Mikoyan, why do I suddenly have a feeling: the MiG-17 is no longer your most advanced fighter jet."

Mikoyan: "Well, this one"

Tang Hua: "Old Mi, Uncle Mi, your design bureau bought a lot of our computers. You bought two T50s, two T52s, and three T53s. Just let me know, and you can get a discount on T54s this year."

Mikoyan: "Huh heh heh heh"

Mikoyan did not answer directly.

Tang Hua also knows that if he doesn't answer, the MiG-19 should have made the first flight of the prototype of the final design not long ago.If Mikoyan leaked that he did have one, then Tang Hua could still congratulate him at the venue—this was the first Soviet supersonic fighter.

Soon after the MiG-17 entered service with the Soviet Homeland Defense Air Force, the Soviet army discovered that the aircraft's flight speed and altitude were not enough to intercept the British Canberra-3 and the American RB-57D high-altitude reconnaissance aircraft.Another serious problem is that the night bombing tactics of the U.S. B-29 and B-36 are becoming more and more proficient, and whether it is the MiG-17 or the MiG-17PF, the combat efficiency is not high during night operations.

Although the S-1951 anti-aircraft missile was in service at the end of 25, this large fixed anti-aircraft missile can only defend Moscow. Perhaps deploying a set in Leningrad can also defend Leningrad. To carry out air defense operations for the entire country, there is no Fighter still doesn't work.

Therefore, the Mikoyan Design Bureau took the task of developing a higher and faster fighter.

The MiG-17 is already a high-subsonic fighter, and it will be supersonic soon.Since the Soviet Union hadn't developed a turbojet engine for high-thrust fighter jets at this time, Mikoyan simply installed two engines on the new fighter jet.

先设计了I-340（SM-1）方案，接着米高扬又设计了一个更奔放的I-360（SM-2）方案，再发展成SM-2B。

The SM-2B is pretty much what the MiG-19 looks like.

Calculating the time, not only the MiG-19 has entered the flight test process, but the MiG-21 is also under design.

Tang Hua: "Comrade Mikoyan, is it... supersonic?"

It was another question that Mikoyan could not answer, but it suffocated him.Even though I am so powerful, I developed the first supersonic fighter in the Soviet Union, and it flew to Mach 1.2 a week ago, breaking the supersonic monopoly of the Western aviation industry, but now I can't say a word, it's too uncomfortable.

"I will soon have a Gold Star (Socialist Labor Heroes Medal)." Mikoyan flaunted a bit insincerely, and changed the subject and said, "Chinese comrades, the development of the aviation industry must be gradual, after all, your foundation is too weak .Learn to make the MiG-17 first, and if you understand it thoroughly, you will also master the basic skills of modern aviation manufacturing. It would be even better if you can also master the manufacturing methods of modern aircraft engines during this process. At that time, the Soviet Union will definitely continue to support you, and you will be able to produce more advanced fighter jets."

What Mikoyan said was actually reasonable.Shen Fei is evolving from an overhaul factory to an aircraft manufacturing factory. The engineers and technicians sent to the Soviet Union to study are all learning from the MiG-15 and MiG-17. After returning to China, they will start the MiG-17 production line for a few years , Transition to a new model after getting started, so the insurance factor is higher.

……

Tupolev also has new orders. This time China will buy another 12 Tu-4s, all of which are in stock.

As an air-to-ship missile launcher, as the first-generation platform for future early warning aircraft and maritime patrol aircraft, Tu-4 is still qualified.But if the aviation industry system takes shape in the future, it is still necessary to develop a universal platform for auxiliary models equipped with four turboprop engines (Picture 4 is a piston engine).

In addition to buying things, there are also selling things.Air-to-ship missile fire control computer & missile fire control system scheme.The Soviet Union did not intend to change the Tu-4. The information provided to Tang Hua was another medium-range bomber, but the model name was erased.

Erasing is the same as not erasing, look at the speed, the range ceiling, and other features, who else can have it except Tu-16.

"When can we make this?" Tang Hua's question was simple.

……

Tu-16 also did not want to.

Unlike the MiG-19, the Tu-16 is now close to entering service.The serial production models are almost leaving the factory, and the first Tu-16 will enter service with the Soviet Air Force in about two months.But bombers are much more sensitive than fighters. After all, the Tu-16 is intended to bomb Europe.The first lasagna hydrogen bomb tested by the Soviet Union in August last year, now the only suitable carrier aircraft is the Tu-8.

"Some things are not easy to buy from the Soviet Union, so let's develop them ourselves," said the chief accountant. "We can make missiles, or several kinds of missiles. Self-reliance should also be able to build up the aviation industry."

Tang Hua: "It's just too slow. Aviation technology is developing very fast in this era. If we build our own factories and train engineers and designers, it will take many years. We must use all available methods to reduce detours. .”

By 1954, the layout of the aviation industry in the country had just begun.

The 112A factory was established in Shenyang, which is a fighter-oriented aircraft factory-jet engine factory-design bureau consortium.

The Harbin Aircraft Manufacturing Factory wants to build a bomber-oriented complex. The current progress is worse than that of Shenyang. It can overhaul the Tu-2 and Tu-4, and is tinkering with the imitation production of the Il-28.

When the Nanchang Aircraft Manufacturing Factory was first built, it planned to manufacture primary propeller trainers.But it is also built in the model of an aircraft factory-jet engine factory-design bureau consortium.

Chengdu is rather strange now. The jet engine factory and aircraft engine research institute were built first, and the aircraft factory has not had time to consider.

Categories that are still poor include:

There is a lack of a second fighter factory, or a design and production complex for small combat aircraft such as fighters and attack aircraft;

There is a lack of a design and production complex for transport aircraft and large service auxiliary aircraft;

There is still a lack of at least one passenger aircraft design and production complex, one of which may be merged with the transport aircraft in one city;

Lack of design and production complexes for one or two helicopters;

Then, there is a lack of a Central Aero Engine Research Institute.This is the Engineering Research Institute linking up with the National Defense Advanced Technology Research Institute. After the Higher Institute has made breakthroughs in basic technology and basic design, the Central Aero Engine Research Institute is responsible for implementing these technologies and entering into model development.

After discussing the exchange and cooperation of military technology, the embassy celebrated the Spring Festival on the second day of the Lunar New Year in the evening.

The hair on Lev Landau's head is still like a bird's nest, and the hairline seems to have receded from two years ago.

"My research in the last year has mainly focused on quantum electrodynamics."

Tang Hua asked Landau about his current research direction, and Landau answered this way.

"I have three papers that have been completed and submitted, and they will be published one after another this year. The first is the topic of eliminating infinity in quantum electrodynamics, the second is the asymptotic expression of the electron Green's function in quantum electrodynamics, and the third is Still a paper on the asymptotic expression of Green's function, but on photons in quantum electrodynamics."

Tang Hua maintained a polite smile, pretending that he was very familiar with the fields of these papers...
