"This is Director Zhang."
Zhang Deqing, Director of Changchun Automobile Research Institute.
"This is Sigchev, the Soviet chief expert who helped build the factory."
"This is Chief Technologist Kachekov."
"This is Meng, the deputy director of the factory, and the chief engineer of FAW."
Soviet chief expert Sigchov first congratulated the cars produced by FAW for passing the driving test.
The employees of the First Automobile Works began trial production in August last year. With the help of Soviet experts, after nearly a year, thousands of types of process equipment have been adjusted, and all production tools have been recalibrated. Most of the more than 1900 kinds of parts made by the factory are qualified.
"The excellent performance of this kind of car is firstly determined by the performance of its engine. The engine has been inspected and operated, and its quality is good. Various parts, assemblies and assemblies have also been strictly inspected. Therefore, now the trial production The car that comes out meets the design requirements."
"This kind of car is more suitable for the load conditions of China's current roads and bridges. If it is driven on a flat road, it can also tow one or two trailers, which can double the load."
"This kind of car can also be converted into variant cars suitable for various special purposes according to needs, such as buses, engineering cars, dump trucks, lifting trucks, etc."
"Modern automobile industry is not only to manufacture qualified cars, but also to carry out continuous, efficient and high-quality assembly line production to improve the performance of automobiles while reducing production costs. The reason why it took a lot of time. With the passage of time, you will understand that this is necessary, only in this way, China can be considered to have established a modern automobile industry, instead of the old Chinese automobile workshops."
After Sigchov finished speaking, the audience applauded enthusiastically.

Liu Nai: "Huh? What song is that singing over there?"
After the leaders of China and the Soviet Union finished their speeches, the atmosphere of the celebration was very active. Both Tang Hua and Liu Nai heard a song in Russian.
Tang Hua: "A Soviet song, "Ode to Our Country's Factory", the main idea of the lyrics should be like this"
"I walked along the factory path"
"At dawn, sing"
"Dear Tree, Dear Plant"
"Your glory will spread throughout the country".
Rao Bin: "The singer is Jiang Jiang, the director of the power branch factory. He graduated from Shanghai Jiaotong University, went to the Soviet Union for further study, and returned to China in January this year. Their current work in the power branch factory is very good."
Chapter 129, Five pairs of wheels
To the west of Changchun City, Shaoguo Town.
This is a field that is not actually empty, with a lot of wheat planted.However, the arable land in Shaoguo Town is currently being cultivated in rotation, with two years of cultivation and one year of rest, so rows of fallow land are interspersed among the arable land.
Changchun No. [-] Tractor Factory put the test site here.
On one of the rows of fallow land, there are a series of eight targets, each of which is 1.5x1.5 meters in size and 0.5 meters above the ground. The red hearts on the white background of the targets are very conspicuous in the green field.
Another row of fallow land is the tank driving area.The distance between the target and the tank driving area is about 1200~1500 meters.
A Type 55 tank started from a distant road and plunged into the fallow land.If an old tank soldier from World War II is observing, you will find that the turret and barrel of this Type 55 tank are not simple: the driving tank bumps with the uneven ground, and the tank even made a small turn to avoid the mud pit , but the direction of the muzzle remains unchanged.
In 1952, it was determined to build the Changchun No. 1953 Tuo (Tan) La (G) Machine Factory. In 54, an agreement was reached with the Soviet Union to introduce the T-[-]A medium tank.
In 1954, the Soviet Union proposed that a ballistic computer for tanks should be developed, and a digital electronic computer should be overwhelmed by the original mechanical computer of the "Patton" type.The Chinese side stated that we are already developing it, but since the imported T-54A is only equipped with a one-way stabilizer, our fire control computer is also based on a monostable artillery system.
The Soviet Union was crazy. In 1954, the Soviet Union had decided to mass-produce the T-54B, and then the T-54B with a three-defense system (that is, the T-55). China has a ballistic computer for a monostable artillery system. How can this be used? ah.
At the beginning of 1955, China and the Soviet Union signed a supplementary agreement, and Changchun Yituo introduced imitation tanks and upgraded them from T-54A to T-54B.
With this upgrade, the Type 1955, which was originally planned to be mass-produced in the second half of 55, was officially mass-produced in the second half of 1956. The military parade in 55 can't catch up, let's catch up with the one in 56.
Although the mass production time was postponed by one year, the model was not changed, and it was still called Type 1.
Liu Nai and Zhang Jue each watched the first parking spot from the sheltered observation post with an artillery mirror. The Type 55 tank was driving at a medium cross-country speed of 25 km/h. It braked suddenly before the first stop. The chassis of the tank shook back and forth twice. Just after the shaking stopped, "Boom!" The main gun fired at the target .
The 100mm high-pressure cannon blew up ripples on the wheat field in front of the muzzle of the tank, and the small piece of wheat closest to the muzzle even fell a little bit.Ripples quickly passed through the 900-meter-wide wheat field, and then - the first target in the target area was shattered.
Zhang Jue: "The first shot hit."
"The hit is certain. It's too unreasonable for such a tank to be missed by a gun of this level," Liu Nai said. "Aiming time?"
"3.76 seconds." Lao Hong, the commander of the test site behind, put down the phone and replied.
After hitting the first target, the Type 55 tank restarted and put into gear. After walking about 150 meters, it stopped suddenly.
Liu Nai: "To be honest, I am not worried about the fire control computer and the fire control system. What I am worried about is the brakes and gearbox of this car."
Lao Hong: "Don't worry, our factory manager cares more about the reliability of the walking system than anyone else. This year's November, the Type 55 will pass Tiananmen Square to be inspected by the chairman. The 20 tanks participating in the military parade are almost watched by the factory manager the whole time. There is no sloppiness in the final assembly. After leaving the factory, all 20 cars have to run laps and do a full set of tests.”
When the three of them were talking, the Type 55 had completed the first 4 shots—short-stop shooting at fixed targets.All four hits.
After the four shots, the tank moved forward for another 300 meters and stopped. This time, it had to stop and shoot at 4 fixed targets at different distances. The shortest distance was 1150 meters, and the longest distance was 1800 meters.
With the assistance of the ballistic computer and the laser rangefinder, another 4 rounds were hit.

"This kind of missile is good everywhere, the only problem is... it's too expensive."
Wang Dayan patted the model of the Air-to-Surface-2 missile on the stand.
Tang Hua: "Essentially, this is a mobile self-stabilizing TV camera system with a coverage of 40 kilometers. There are only four TV stations in our country, and Beijing TV is the only one with a mobile TV camera car."
The United States is indeed ahead of China in the development of TV-guided air-to-surface missiles.The air-to-ground-2 missile has just produced a prototype of the guidance system, and the AGM-12 in the United States has completed the phase-2 test launch.
Air-ground-2 is now a tentative name. What will be the name after it is officially installed? We still have to wait for the Air Force to decide whether to develop a new series of "light tactical air-to-ground missiles".
If Oldford could get a peek at the KL-2 model, he wouldn't be offended "the Chinese stole my idea" because the missile looks nothing like the AGM-12.In fact, it is a bit like the AGM-65 "Maverick", but the AGM-65 has not yet been made.
The missile has a total length of 2.55 meters, a body diameter of only 30 centimeters, a maximum range of 22 to 24 kilometers, and a warhead of only 60 kilograms, while the AGM-12 is 100 kilograms.
But there is one thing that Americans must be very surprised. The warhead of the Airland-2 is a shaped armor-piercing warhead, and AGM-12 is still struggling with whether to change the high-explosive warhead into an armor-piercing warhead.
"Has Dalian Jianxin Company started designing the armor-piercing warhead to be used?" Tang Hua asked.
Wang Dayan: "It's probably started. But I don't think the armor-piercing warhead is important at all. The bullet diameter of this thing is 30 cm, and the diameter of the drug-shaped cover is 27 cm. I design a conical copper cover with a compass curved plate. It can easily break through 500mm homogeneous steel armor. Now the main thing is to wait for the 112B to blow out the aerodynamic control parameters, and try to build a sample bomb to see."
Tang Hua: "Maybe the frontal defense capability of tanks will be [-] or [-] millimeters in the future."
……
The development of the optical contrast searcher is equivalent to the completion of the research on the core technology of the Air and Ground-2. Next, we do not plan to set up a finalized research team. The model of intensive work and testing to complete the missile within a few months is suitable for wartime Or when the war is approaching, it is unnecessary now, and the step-by-step development can reduce project costs and save staffing.
The way to reduce the manufacturing cost of Void-2 is to increase the output of TV cameras and reduce the operating expenses of the factory.To increase the output of TV cameras, it is necessary to increase the number and coverage of TV stations.
