Back to the Republic of China to be a editor

"President Truman solemnly stated that he hoped that the situation in the world would never warrant the use of atomic bombs. The President told the Prime Minister that he also wished to keep the Prime Minister informed of developments which might alter this situation."

The Anglo-American joint communique, while denying that the United States would use the atomic bomb, um, also sued for peace.

……

The first stop, Changchun; the second stop, Shenyang; the third stop, Dalian.

Returning from the 50 center, you have to go around and go back to Beijing.

"Minister Tang, the main equipment of Factory 112B has been installed, and more than half of the equipment has been debugged. Production preparations can be completed by the end of this month."

In the east area of ​​Air Force No. 112 No. 30 Factory, which has been designated as Factory [-]B by default, Huang Zhiqian introduced the equipment installation and commissioning situation of the factory area to Tang Hua.

Punching machine, planer, milling machine, grinding machine, sawing machine

Thread processing spline processing gear processing engraving machine...

I went over the stockpiled aluminum materials, steel bars, copper wires, rocket engines and fuze warheads from Dalian, which were prepared for official production.But Tang Hua didn't get off the car in Shenyang specifically for a routine production inspection. "Old Huang, you just need to continue working in the east area of ​​Factory 38. How about we go to the west area to see new guys now?"

The west area of ​​Factory 38 is where the main workshop of the original aviation repair factory is located.In addition to dense workshops and warehouses, there is also a 2000-meter airstrip.After all, in the aircraft overhaul factory, the aircraft that leave the factory must undergo a test flight before returning to the army.

A few months ago, Tang Hua asked the Air Force for two Tu-2s, and for a few more gliders to be converted into towed target aircraft for live ammunition target shooting tests of anti-aircraft missiles.Liu Yelou frowned. Although he agreed in principle, he still expressed concern about the safety of the main machine that towed the target.

When Tang Hua came back to think about it, he also felt that there were some problems.Naturally, the fire control radar of the air defense missile system will not make mistakes. With a 1000-meter-long cable, the distance between the target aircraft and the parent aircraft is 1000 meters. Within 8 kilometers, the radar is still relatively easy to distinguish.

But what if the operator made a mistake and the radar pointed directly at the mother machine?

In addition to operator mistakes, there is another problem, that is, missile mistakes.Live ammunition shooting will often have a missile trailing the target aircraft, if the missile tail chases the target aircraft, and the radio proximity fuze is not triggered by the electromagnetic signal feedback of the target aircraft, the missile surpasses the target aircraft and continues to fly forward, then it can drill near the parent aircraft went.

Or an unmanned remote control drone is the safest.

After sending a telegram to Huang Zhiqian, asking if there were any second-hand goods stocked by the Japanese devils in the warehouse of Air Force No. target drone.

The car drove into the west area of ​​Factory 38, and the gate of a hangar had been opened.

"This is... Isn't this the Nakajima Type 91 fighter jet?" Tang Hua looked at the unmanned target drone in the hangar with joy.

Nakajima Type 91, a high-wing fighter developed by the Japanese Army in 1928. Although it evolved from a biplane to a monoplane, its flight speed is only 300 km/h.

From 1931 to 1934, Japan produced a total of 320 Nakajima Type 91s. In the early 30s, many of them were assigned to the Kwantung Army, and all of them were suddenly retired in 1937. Therefore, finding a few Nakajima Type 91 engines in Shenyang’s aircraft repair shop should be It is not difficult.In fact, what Huang Zhiqian found was not only the Nakajima Type 91 engine, but also a lot of broken Nakajima Type 91 fighter fuselage components in bulk. After mobilizing workers, the first target drone was built.

"We found the most waste parts for this kind of aircraft in Factory 38," Huang Zhiqian said. "Based on the results of treasure digging so far, a total of three Nakajima Type 91 unmanned target drones can be assembled. In addition, we can also assemble A Mitsubishi Type [-] reconnaissance plane and a Kawasaki Type [-] fighter jet."

This is fun. They are all old antiques from the early 30s. Since Huang Zhiqian said he could do it, the assembled plane will definitely be able to fly again.The only problem is that these target drones are a bit slow, with a maximum flight speed of two to three hundred kilometers per hour. It is also common for American jet fighters to fly at low altitudes at speeds of six to seven hundred kilometers per hour.But because it's crude and simple, I don't care so much.

In order to develop unmanned target drones, Huang Zhiqian applied for the establishment of an unmanned aircraft research room in Factory 38. This is also the first aircraft (including target drone) development and design department of Factory 38/Shenfei.

"The automatic take-off control system is made according to your design concept drawing."

"Remote control. The antenna on the ass of the plane is a radio receiver."

"Semi-automatic flight stability control system."

Tang Hua looked at the system one by one, and the unmanned target drone of this era is a remote-controlled model airplane, a large model airplane.

In order to shorten the development cycle and actually simplify the design, Tang Hua told Huang Zhiqian not to engage in the landing system, but to directly recover with the rope net.After all, the fastest speed of these three target drones is only 300 km/h, and their minimum take-off/landing speed can reach about 100 km/h, and the weight is a little over 1 ton, and the rope net is directly caught.This has continuously shortened the development cycle of at least one month, and it can also make the target drone much cheaper.Landing gear and landing remote control circuits can be worth a lot of money.

Put a little oil on the Nakajima Type 91 unmanned target drone, and the workers of Factory 38 dragged the target drone out of the hangar and to the take-off point of the runway.Start it with the crank, and wait for the aircraft engine to "chug and chug", and the workers evacuate quickly.Huang Zhiqian pressed the remote control and directed the classic machine to accelerate into the air.After turning around in the sky for a few times, using a telescope, you can see that the light on the target drone used to indicate the amount of oil changes from flashing green to yellow and then to red, indicating that the oil is almost burned out.Huang Zhiqian, who remotely controlled the plane at the end of the runway, let the plane come down and plunged into the rope net used for landing deceleration.

"Old Huang, we will leave on January 1, after New Year's Day, so please remember the time."

The shooting range is in the Ming Tombs in Beijing. Of course, all the target drones must be boxed and packed, and transported to Beijing by train for assembly.

Shenyang makes target drones, but the next batch of missiles for target shooting and testing is not yet produced in Shenyang, but in Dalian.

Speaking of which, Liu Nai has been squatting in Dalian for more than two months, and may continue to squat.With the fierce fighting on the Korean front, Dalian's military production was under too much pressure.

"Minister Tang, from December onwards, the production capacity of 12 fires and 40 fires can basically meet the needs of the frontline. Do you have any new weapons you want to make this time?"

Tang Hua: "This... I don't have an idea yet. Why don't we see the feedback from the commanders and fighters fighting on the front line?"

I just want to see if the last batch of target-shooting test bombs for anti-aircraft missiles are ready...

"What else can there be in the feedback? It's all applauded. Those who went to the War to Resist US Aggression and Aid Korea are veterans of many battles. They have used a lot of guns. When compared, the pair of 40 fire and 108 fire can only be praised. But let's talk about ideas... the front line The commander doesn’t have one, but I have one on my side...” Liu Nai rubbed his head, “Just this rifle. Is there any way to make the rifle more accurate?”

"You mean a rifle that shoots far and accurately?" Tang Hua was surprised, but after thinking about it, he thought it was reasonable.One of the most famous things that Liu Nai did in the arsenal in the base area was led by Li Qiang. He actually made the Bayi-style horse rifle in a small workshop repair factory in the base area.So Liu Nai is actually a gun fan?

"To tell you the truth, brother, my marksmanship is still good. I work part-time as a gun tester in the arsenal in the base area. I have to fire three rounds of the guns I repair and build before leaving the factory."

"That's great, this is interesting." Tang Hua smiled, "Okay, let's do this! But, not so fast."

As we all know, in 1950, China did not have the production capacity of optical instruments, even military binoculars could not be produced.Fortunately, there is also a great socialist family, as well as Dongcai—Zeiss Jena, the East German branch of Zeiss Company that was split into two because of World War II.

Tang Hua feels that he or China's heavy industry department has become a major customer of Dongcai. In the early 50s, I went to order the sights for the radio-guided bomb system, followed by the optics for the night vision/infrared system, which were bought in bulk, and now I have to add the scope for the sniper rifle.

I simply wrote a specification request form for an 8x optical sight, specifically mentioning the need to customize a 20mm-width horizontal groove nut tightening device, and send it to Beijing first, and let Zhou Kuan take it to Wang Dayan for refinement, and then hand it over to the Ministry of Foreign Trade Send an order.

What caliber to use for the sniper rifle... In fact, there is no choice.

12.7毫米子弹不考虑。虽然大连建新公司在生产美式12.7X99弹，可能要转产苏式12.7X108弹，但现在唐华还没有信心把12.7毫米步枪的重量降低到人力可以方便携带的程度。

8~9mm ammunition is not available now.It can only be selected from the traditional standard rifle ammunition of 7~8mm.

7.92. The 57X6.5 projectile is too heavy, and the initial speed catches the chicken.The Japanese 7.7 and two [-] bombs are more slag, so they are directly excluded.

The American 7.62X63 is quite good, but it is not the model of our army's mass-produced equipment.

Only Soviet-style 7.62X54R can be selected.

There is nothing else to do next, probably let Liu Nai keep an eye on the newly established Soviet-made 7.62X54R bullet production line to see if there are any outstanding skilled workers who can be drawn out.The rest will wait for Dongcai's goods to arrive in a few months.

Chapter 98, Is overselling to the Soviet Union?

Moscow, Bowman Institute of Engineering.

Oleg, a professor at the School of Aeronautical Engineering, hurried from his office to the computer room.As he approached the door, he saw two of his graduate students hurrying out of the computer room with their schoolbags in their arms.

"What happened?" Oleg asked confused.

"Professor, you will find out when you go in and have a look. Oh, Aunt Tatyana is also inside."

Oleg slapped his head, it's too bad.

"Tania, why did you bring so many people here to borrow computers?"

Tatiana, the wife of Professor Oleg, was the head of the domestic economic census and survey department of the Central Statistical Bureau of the USSR.It is already mid-December, and the routine economic statistics at the end of the year will begin again.The planned economic system of the Soviet Union, which has been in operation for more than 12 years, must rely on comprehensive statistical surveys of national conditions. At the end of each year, various departments and departments of the Central Bureau of Statistics have to face piles of data.Professor Oleg saw that his wife was so busy recently that she not only worked overtime for two hours a day, but sometimes she had to bring a pack of information forms back home and fill them out while doing calculations. He told his wife that their college bought an "electronic computer" in September this year. Seems to speed up calculations.

On a Sunday afternoon, Oleg took Tatyana to the academy, turned on the computer and asked Tatyana to perform some "simple calculations" using the work the computer gave her.

The next day, Monday, Tatyana took all six employees of the department and occupied Oleg's computer.
