This seems to be off topic again...
After solving the problem of the remaining workload of the KL-2 missile project, Tang Hua also went to Shaoguo Town to watch the excitement.
"After two years in Changchun Mao, the Type 55 fire control system has been completed, which is not a small achievement." Tang Hua said to Zhang Jue.
Zhang Jue: "I used to have a little foundation in making missile fire control computers, but at least 70% of the computers used in tanks are brand-new concepts. When I first took over, I was stunned for two months. Thanks to the five-member team brought over They are all capable, stumbled and walked the right path.”
Tang Hua laughed and said: "You may have been too busy to pay attention to the outside world in the past two years. If you look at the tanks of the same generation in other countries, you will know what a great piece of equipment you have made. In 1957, the academic committee was elected It's about to start. The development of the fire control system and the ballistic computer has come to an end. Please sort out your materials and the materials of this project and send them to the General Office of the Chinese Academy of Engineering. Remember that it is the Second Secretariat of the General Office of the confidential project. "
Currently a member (academician) of the Department of Electronic Information Engineering, Huang Kun and Xie Xide are in the integrated circuit project; Wang Dayan is in the optoelectronics project; Lebedev and Wang Shoujue are in the Shanghai Institute of Computer Science/Communications.Beijing Computer Institute/Communication Institute... Zhang Jue has not been on the Internet for 55 years.
The Shanghai Institute is far away, and Tang Hua will not squat there all year round. Usually, he will give Wang Shoujue a general direction and encourage him to do it by himself, or work together with Lebedev.Zhang Jue... In the first few years, he was always regarded as a tool man by himself.
But now he is no longer a tool man. The fire control system and ballistic computer of the Type 55 tank are basically independently developed by Zhang Jue. In addition, the encrypted computer Zhang Jue is also a major participant in the early and mid-term.
With these two world-leading projects in hand, Zhang Jue could be a member of the academic department in 57.

"In the test this morning, the static-to-dynamic hit rate of the Type 55 tank is infinitely close to the static-to-static short-stop shooting, that is to say, it is not less than 1500% within 90 meters, which is a bit impressive," said Deng Jiatai, deputy chief of staff of the armored forces. "It is not an exaggeration to say that if this system is used on the battlefield, in a plain area like Europe, as long as there is not too much difference in the number of the two sides, it is impossible for 'Patton' and 'Century' to defeat Type 55, T54B."
Tang Hua: "Looking at the items of the test and assessment, the moving target moves in a straight line at a constant speed. If the target moves in a straight line with variable speed, or even a variable speed and line motion, then the hit rate should not be so high."
Deng Jiatai: "The hit rate will decrease, but at this time we have to rely on the gunner's training level and operating experience to predict."
Tang Hua: "No, this shows that the fire control system still has a lot of room for improvement. In the future, the computer will learn the gunner's combat experience and prediction methods."
Deng Jiatai: "...Minister Tang, you are making the training director of the armored force lose his job."
Tang Hua pointed to Zhang Jue and asked him to talk to Deng Jiatai about the technical development route.
Zhang Jue: "The next step in the development of tank fire control systems and computers is to firstly integrate day and night, the second step is to strengthen sports shooting capabilities, and the third step is to increase the hunting-killing function and automatic tracking system. The automatic tracking system involves image recognition. , is the most complex and tests the capabilities of computer hardware, which will likely be developed in the third phase."
Tang Hua: "This means that the training director will continue to work for another 10 years, so things are not that bad."
……
For the current Type 55 tank, the main gun shooting method recommended in the training manual is stationary or short-stop shooting during the march. The hit rate of these two combat methods is relatively guaranteed.
However, after being equipped with bistable and first-generation electronic fire control systems, the Type 55 tank has limited on-the-go shooting capabilities, but the hit rate cannot guarantee that it will destroy targets within a common combat distance within a limited time.
Although shooting on the move was not the main item of the assessment, it was still conducted today.
"Is the driving speed still 25 km/h?" Tang Hua asked.
Deng Jiatai: "Yes."
Tang Hua: "If it is reduced to 15 km/h, the hit rate can actually be slightly improved."
Zhang Jue: "That's it. Sports shooting is a simple test. It doesn't matter how many shots you hit."
The Type 55 tank was still driving in a straight line on the fallow land as it was a few days ago, with the muzzle pointing at the target area.The gunner felt that he had almost aimed, and opened fire.The tank shook suddenly, and the tracks slipped slightly to the left.
The first shot flew.
"It seems to be about the same!"
"Looking at the smoke and dust rising from behind, the point of impact is about two meters behind, a distance of 1200 meters. This is very good, and it is not a random hit."
The second shot flew.The third shot hit.The fourth shot went flying.
The total hit rate is 25%.Except for the fact that the second shot was a little too far, and directly blasted a large area of wheat between the target area and the driving area, the first and fourth shots were actually quite accurate.
Deng Jiatai: "The current fire control of the Type 55, sports shooting is actually a bit useful. Have you ever thought that in cities, villages or similar close-range encounters, the distance between the two tanks is less than 500 meters, or even less than 300 meters? At this time, the sports shooting can actually hit the enemy tanks."
……
The Type 55 tank continued to be tested in Changchun, and Tang Hua directly handed over full authority to Zhang Jue for the fire control system/ballistic computer, so he didn't have to worry about it.
I have traveled a lot this year. I have gone to the Soviet Union twice since New Year’s Day. I have traveled a total of 4 kilometers by train. Now it’s time to go to Beidaihe Zhai for a month.
Wuliang Suhai.
Today the test site is used by the Ballistic Missile and Launch Vehicle Research Center.
On the launch pad is a rocket that is much thicker than Dongfeng-1/TK-3.
But it is not Dongfeng-2, to be precise, it is the first level of Dongfeng-2.The rocket engine is a 67-ton liquid rocket engine, and the fuel tank and oxidizer tank are also designed according to the design.But there is no second-stage engine, but a counterweight; the original 2.2-ton warhead is also a counterweight.
Therefore, the design length of this test bomb is much shorter than that of the full version of Dongfeng-2, with a total of 17.5 meters.
"5, 4, 3, 2, 1, launch!"
The first-stage rocket engine of Dongfeng-2 spews orange-red flames downward, which is much larger than that of Dongfeng-1.After the engine works stably, the flames ejected become incandescent and glowing orange, and the rocket rises slowly. When its tail leaves the upper edge of the launch pad, it is actually about the same speed as a person riding a bicycle, but the acceleration is getting faster and faster. After half a minute, the people at the scene can only look up at the little bright spot in the sky.
Four radars are tracking the missile. This time, the Dongfeng-2 first-stage test missile hits a high trajectory. The rocket will not fly too far, and will eventually land on the edge of the western area of Uliangsuhai, but it will fly very high.
“100公里”“150公里”“180公里”“200公里”“240公里……”
Ren Xinmin supervised the battle at the test site.Listening to the report in the command center, I first estimated the working condition of the missile engine in my heart.
"Old Feng, what is the maximum tracking height of the radar?" Ren Xinmin asked.
Commander Feng: "In terms of the ultimate tracking altitude, it must be the Alxa tracking radar station that is far away from us. At the maximum elevation angle, it can track targets at a height of 400 kilometers. Why, is this not enough?"
Ren Xinmin: "Enough is enough... this time is enough."
Chapter 130, Karlovy Vary International Film Festival
Returning to Beijing from Changchun, Tang Hua began to want to get off in Shenyang to see the progress of Anshan this year.
How about Anshan Iron and Steel's production-technology research and development management reform from the rolling mill? Is the continuous rolling mill in sight?
However, Anshan Iron and Steel's production-technical research and development innovation should not be so fast. Reform-try-readjust-try again in production will give them an environment to explore by themselves.As for the continuous rolling mill, that is not my field of expertise, so let the research station of the General Iron and Steel Research Institute in Anshan figure it out.
In addition, Angang No. 8 blast furnace opened in August, with an annual output of 75 tons.Anshan Iron and Steel's previous annual output had reached 250 million tons, and when the No. 300 blast furnace opened, Anshan Iron and Steel has entered the world-class large iron and steel enterprise club of [-] million tons.
Not only has the output increased by 300 million tons, but the total number of employees at Anshan Iron and Steel is now 20300. Since 1953, it has been improving job efficiency, and the number of employees only increased by 9 when the No. 270 blast furnace was added.Moreover, these 2 employees have already included more than 1000 repeated positions, serving as talent seeds for new steel plants in other places.
Carrying out cost accounting, Angang Steel's current steel cost price is about the same as that of US Steel.However, if the wages of 2 workers are converted according to the employee wage standard of the U.S. steel company, the cost price of steel is 1955% of that of similar products in the U.S. steel factory in 160...
It's so far behind.Hmm, something seems wrong.It's the wrong exchange rate.
It is now mandatory to exchange 5.5 RMB to 1 US dollar, which is actually overvalued (to facilitate imports). Taking into account the average price of various industrial products, and referring to the black market price in Hong Kong, the reasonable exchange rate for this period should be 7 RMB to 1 US dollar.Calculated in this way, the cost price of Anshan Iron and Steel is 125% of that of the US steel plant, which is still a little bit worse.
However, considering that Anshan Iron and Steel uses low-quality iron ore, and iron ore and coal are transported by relatively expensive railways, this needs to be cut by 10% to 15%. The cost price of Anshan Iron and Steel is 110% to 115% of that of American steel mills.
The conclusion is: In terms of Anshan Iron and Steel itself, the labor productivity should be close to that of American steel mills in the same period.
