"How is it, Professor Wang?" Tang Hua pulled off his gloves.Over the past three days, more than half of the time has been spent in the laboratory every day. Now the TKN circuit and amplification part have been completely modified by Tang Hua. If the estimation is correct, it will be no problem to fire at the normal engagement distance of the tank gun at night.

"I've finished my research here too." Wang Dayan hasn't done any destructive and violent experiments in the past few days, and spent most of his time checking the manual of TKN and the manual he brought, or measuring the lens with a spiral micrometer. "Well, the position of his second lens is wrong. There will be misfocus."

"Then let's make a new one. Correct this, and the effective detection range of this night vision device can be improved a little bit."

"Now there is no factory in China that can do it, so we have to find a foreign country to order. My suggestion is to go straight to Minde and find Dongcai."

"Kunming, ah no, can the No. [-] Arsenal in Guiyang do it?"

"I'm very familiar with that bad factory, don't count on it." Wang Dayan looked disgusted, "Let's not talk about the grinding accuracy of Factory 53, and even the optical glass is not produced by ourselves."

It is impossible to make domestically produced products, and it will not be possible within three years.Domestic precision optical instruments have to wait for Project 156. Even if they ask the Soviet Union's big brother to build a factory in advance, it will take at least three years to start production.

Tang Hua began to make a list of equipment that must be imported for night vision devices.There is one lead sulfide device, and one optical lens group. The price of this optical lens group is several times more expensive than the lead sulfide device.

Others seem to have no major parts to import.

As a poor rabbit with a perennial shortage of foreign exchange, I can save some foreign exchange if I can.

"Professor Wang, the Ministry of Electronics and Information Industry is now going to build an optoelectronics institute and an assembly plant in Changchun. The assembly plant will definitely be expanded into a precision instrument factory in the future. The factory will be integrated into one, specializing in precision optoelectronic instruments." After the night vision device was completed, Tang Hua started Pull people, "How about it, after Mr. Zhao's laser is finished, go to build the Changchun Photoelectric Institute?"

Wang Dayan: "Wait, shouldn't lasers also belong to the field of optoelectronics?"

"Of course it is within the optoelectronic field system. And after the successful development of the laser, it will soon enter the product project approval. I need these products in a hurry. These lasers and laser products will be developed in Changchun Institute. In the future, we will work on the laser industry. , Tsinghua University is responsible for basic science and breakthroughs in basic technology, Changchun Institute of Optoelectronics is responsible for applied technology and engineering design, and Changchun Precision Instrument Factory is responsible for production.”

Shenyang, Beiling District.

Air Force No.30 Eight Factory.

Seven or eight huge warehouses have been vacated, and Huang Zhiqian took the personnel of the missile manufacturing project from Dalian to Shenyang and settled here temporarily.

The engine of the Hongqi-1 missile is still manufactured in Dalian, and Shenyang manufactures the missile body, radio receiving components, control components, and warhead.The train brought all the machinery and equipment needed for missile manufacturing, and the project team, with the help of the personnel of Factory 38, formed a construction team to seize the time to install and debug the equipment.As for the sleeping place, the dormitory has not been vacated for the time being. Besides, the dormitory is far away from the factory area. In order to save some walking time when going to work, the project team slept on the floor in a heated warehouse.

"Is that Factory 38 over there?" Huang Zhiqian asked looking at a large gray building on the west side of the missile factory.

"Yes, in fact, this is also the scope of Air Force 38 Factory." The local dispatcher in Shenyang replied, "I heard from the factory manager that our factory will be adjusted soon. Our factory will be changed to No. 112 in the future. There are two branch factories. 112A makes aircraft. 112B builds missiles."

"The plane is the most exciting thing." Huang Zhiqian said suddenly.

"Let's be more realistic. How can we develop the aviation industry based on our current industrial foundation? Doesn't that mean that if a child can't walk, we want him to run away?"

"To tell you the truth, I have designed aircraft abroad." Huang Zhiqian said, "I was an employee of the Convair Aircraft Manufacturing Company in 43. I participated in the design and manufacture of the B-24 bomber, and I also did stress for the 240 twin-engine transport aircraft. Analysis. Then went to England and designed jets at Gloucester Aircraft.”

"But, our material foundation is too poor now. We can't do anything if we have talents without machines." The dispatcher is not a novice, and he has also done complex work such as overhauling fighter jets. The overhaul is done well, and when the conditions permit in two years, we will rebuild our own Chinese aircraft.”

Beijing, Nanyuan Airport.

"This trip to the Soviet Union must be modest and prudent. We must explain to the Soviet comrades that our country has no aviation industry foundation and must build from scratch. The scale should be smaller, mainly to meet the needs of repairs and ensure the Korean battlefield. This is because we have just Jianguo is still very poor, and has no strength when it grows big. Our country’s aviation industry has no foundation. In principle, we rely on them when negotiating. We must enlist the comrades of the Soviet Union to help us establish the aviation industry. Send a telegram or phone to the country for instructions."

Nie Shuai, Dong Biwu, Dong Lao, and Air Force Commander Liu Yelou saw off at the airport the delegation going to the Soviet Union to negotiate and assist China in establishing the aviation industry.

Duan Zijun and Shen Hong nodded after hearing Nie Shuai's words.

"Comrade Wang Ruofei is still in Moscow right now. When you arrive, meet him first." Elder Dong said, "Ruofei has been in the Soviet Union for a long time this time, and he has a lot of experience in negotiating with the Soviet Union. You are also in Moscow. You can ask him these questions."

In order to enable the aviation industry to meet the urgent needs of the War to Resist U.S. Aggression and Aid Korea and complete the evolution of the domestic aviation industry from "repair to manufacturing", the Government Affairs Council, after discussing with Soviet consultants, formulated a plan in November 1950, and the start of the aluminum industry was only considered as such. components of the program.

The Air Force can't rely on buying other people's planes.However, China now has an air force first, and is fighting a war in North Korea. A large number of combat aircraft are in urgent need of repair.Therefore, the development path of China's aviation industry still has to be repaired first, then manufactured, and then developed to the path of self-design.The principle is from small to large. When designing a repair shop, it is necessary to consider the arrangement and deployment of the future transformation into a manufacturing plant.

这个航空工业计划的核心内容就是：用5至8年时间，试制成功雅克-18活塞式教练机和米格-15比斯（后改为米格-17）喷气式战斗机。与这两种飞机对应，国内要建立两个飞机制造厂。雅克-18定在南昌，建立南昌飞机制造厂。米格-15比斯定在沈阳，要把空军No.30八厂改为沈阳飞机制造厂（112A厂）。

Chapter 84, Chinese Army, I understand

The aviation industry delegation bid farewell to the vice premier and commander, boarded the plane and went to the Soviet Union for negotiations. When they returned to China in early 1951, they would bring back from the Soviet Union two aircraft factories, a jet engine repair factory and a piston engine repair factory, an aviation instrument factory, and an aviation electrical equipment factory, and China's aviation industry system had just started.At the same time, a new Bureau of Aviation Industry will be established under the Ministry of Heavy Industry, which will later be the Third Ministry of Machinery Industry/Ministry of Aviation Industry.

In the last two months of 1950, many large iron cabinets were placed in the supercomputing hall of the Shanghai Institute of Computer Science. 16 iron cabinets formed a big "X" shape. Lebedev sometimes worked at his desk, and sometimes worked with his assistants Debug software and hardware next to the big iron cabinet. The computing unit of the TC51 supercomputer is different from that of the T50, and the operating system must be modified accordingly—although there are not many Kbytes of code in total.

Still in the Shanghai Institute of Computer Science, another area, the prototype of the T51 general-purpose computer is also being assembled.In fact, the on-site workers, technicians, and even the ordinary staff of the research institute didn't quite understand the underlying design of this computer. Anyway, they just followed the technical information and drawings left by Tang Hua.

The Radar Institute has just handed over the two types of radars for the Hongqi-1 surface-to-air missile. Although they were modified from the Soviet-made small search radar and anti-aircraft gun control radar, the work is really not easy.Now the radar institute is still busy, and the second phase of development tasks has been issued to develop two types of airborne radars.

In Guangzhou, Huawei is producing remote-control TVs at a leisurely pace—only in the European and American markets, and the shipments are just enough to keep the TV department from starving.Radar displays and night vision displays are the business of the Military Display Department.

In Nanjing, the just-planned Electronic Countermeasures Research Institute is digging ground.

In Changchun, the Institute of Optoelectronics is also under construction. In the former capital of the Puppet Manchukuo, a big house in three provinces and six ministries has been requisitioned as the office building of the Institute of Optoelectronics. Now it is full of messy building materials and equipment.

Tang Hua did not place the Institute of Optoelectronics in Changchun solely for the purpose of replicating the famous Changchun optical machine. There is also a very realistic reason: from the beginning of 1951, the Soviet Union was about to hand over tanks and self-propelled artillery to China. Hand over tanks to China, Changchun is on the rail line into China.In this way, at the beginning of 1951, when Soviet tanks got off the train in Changchun, they could modify the night vision system on the spot.

Throughout the Yangtze River Delta region, Shanghai, Suzhou, Taihu Lake, Xishan Island, Wujiang, Kunshan, and Taicang, there are scattered large or small factories. The products range from iron sheet, steel wire, aluminum plate, copper wire, silicon block, germanium ingot, to transistors, circuit boards, and magnetic cores. Memory; then to the T50 computer, the guidance components of the Air Control-1 bomb, the radar, the walkie-talkie...

In China today, if you ask which industry has the most complete system, it is probably the electronics industry.In a few years, if the heavy industry system can fully support the manufacture of industrial mother machines, then the whole industrial chain will be in hand.

North Korea, Peace Cave.

Nearly a hundred South Koreans and Americans with dejected expressions and dozens of wounded on stretchers were brought to the border of the area controlled by the two armies, which was the agreed place to hand over the prisoners of war.

"Mark Gasol, Private, Company A, 8th Regiment, [-]st U.S. Cavalry Division; Anunoby, Sergeant, Company A; Chris Boucher, Sergeant, Company F; Brissett, Private, Company E; Powell, Lieutenant of Company A, here is Mr. Powell's leg."

The personnel of the volunteer army who came to negotiate held the list and compared the wounded one by one.Poor Norman Powell lay motionless on the stretcher except for the occasional rolling of the eyeballs.The negotiators carried him to the US negotiating team, and handed over his foot, calf, and a small piece of thigh frozen into an ice lump to the US negotiating team.

"To show our sincerity, we have also handed over 30 captives to you," the US negotiators also said.

When Walker learned that the Korean People's Army and the Chinese Volunteer Force offered to hand over the prisoners of war, he was also surprised for a while.His first thought was that "these Chinese really don't want to cause too much trouble", and then Walker felt that the captives should be exchanged back and forth.After reporting to MacArthur for permission, he also selected 30 of the [-] or [-] volunteers captured by them and returned them.People's Army prisoners?No, this exchange of prisoners is to send the Chinese out of the country as a gift, and has nothing to do with North Korea.

"Sergeant Terrence Davis, where were you on the night of November 1950, 11?"

Officers from the 8th Army, the U.S. Army Intelligence Service and the Investigation Service are questioning the returning prisoners one by one.

From the night of November 11st to the morning of November 1rd was a rare moment of disaster in the history of the US Army. A heavily armored mechanized infantry regiment was suddenly devastated—or it could be said to be annihilated. You must know that on the US military battlefield in World War II The largest unit that was wiped out was the regiment (those who surrendered the entire country in the Philippines are not counted).What happened in this day and two nights, the investigation department needs to give a detailed report.

"On the night of November 11, I was at the No. 1 Military Station on the north side of Yunshan City. I manipulated a heavy machine gun on the west wall of the military station. Most of our 8th Regiment and First Battalion are in this military station."

"When did the fighting start?"

"I think it was about 7pm when we suddenly came under shelling."

"Did you observe what kind of artillery the shelling came from? How long did the shelling last?"
