For people from the grassland, both men and women love to drink, so this cup of beer is not much different from boiled water for Wang Xiaoyu.
While drinking and chatting, this way of dating old friends makes people feel relaxed. However, Wang Xiaoyu's heart was still a little strange at this time. Brother Zhenhua came to find Mia. Is it really for the sake of old age?
Friends reminiscing about the past?
This is not in line with his style.
"Qin, I really didn't expect that we would meet again so soon." Mia took a few sips of beer, her face turned red, and her words became bolder: "After returning to Germany, I have always missed you..."
"Cough, cough." Qin Zhenhua coughed twice. He knew that foreigners were very bold and would say it in their hearts. However, this was just thinking, and they would not act properly.
"Mia, I'm here to find you. It's a trivial matter. I want to ask you for help." Qin Zhenhua said: "After all, I'm the only friend here, I can only find you."
Mia smiled on her face: "I know that your motive is impure. If it weren't for my help, I wouldn't want to come to see me at all. Tell me, what's the matter?"
"My wife is doing academic research with her tutor." Qin Zhenhua said: "In their university laboratory, they want to import an optically used four-axis single-sided fine mill."
As soon as these words were said, Wang Xiaoyu felt a sense of gratitude and guilt in his heart. How could he doubt his husband? Although he had not officially gotten married, the two were already engaged. Even if they were a couple, he would go to see his confidante.
, I took me there, not secretly coming out for a try, and the most important thing is to work.
Every time I go abroad for an inspection, there will be corresponding university quotas. Capital Institute of Technology is in the industry, so there are naturally opportunities. By the way, it can also complete some academic exchanges.
Take the current example. The four-axis single-sided fine mill used optically that Qin Zhenhua mentioned is indeed a device they urgently need. When doing scientific research, without this equipment, it will take a lot of time.
Hand grinding, and the accuracy is not guaranteed.
On the way here, everyone sat together and chatted. Wang Xiaoyu remembered that Professor Cao had mentioned this thing. Unexpectedly, Brother Zhenhua remembered it and actually came to Mia to discuss it in person?
Hearing Qin Zhenhua's words, Mia stared at Qin Zhenhua with a smile on her face, looked at her for a long time, and then said, "In the university laboratory, you should have a high demand for spherical finishing mills, right? Plane,
Or four-axis, high-precision, I guess, are you planning to polish prisms?”
Mia was also quite smart and guessed Qin Zhenhua's intention at once. He came here to find a way out for civilian heavy trucks. However, since he came here, he had to do more things to save money from wasting air tickets.
This kind of optical processing equipment, when it comes to Qin Zhenhua's identity, Miya guessed Qin Zhenhua's thoughts at once.
This is to prepare for the new generation of fire control systems!
The earliest fire control system was an optical lens with complex scales on it. Then, according to the target's situation, various launch parameters, wind directions, etc. were bound, and then aimed at shooting.
This fire control system is simple and primitive, and can only be stopped and it will definitely not meet the demand. Later, the turret of the tank gun began to adopt a stable system. Through a certain amount of advance, it has the ability to shoot automatically, and even added
With the automatic metering system, a lot of data is automatically bound.
However, in the era of rapid development of fire control systems, this automatic metering system has long been behind. After the introduction of L7 tank guns from the UK, the relevant disturbed fire control system was also introduced, which is the automatic
Compared with the fire control system installed in the meter, it can measure more error parameters of tank guns, such as the tilt of the cannon, motion state, etc., and eliminate it. In addition, an improved disturbed tank fire control system was introduced from the UK, which uses electrical synchronization methods to realize the artillery.
It is automatically synchronized with the aiming line, thereby improving the response speed and accuracy of the fire control system.
However, this is still the simplest fire control system. The simplicity of it is that the fire control system belongs to the artillery. Wherever the turret turns, the fire control system will turn, and then search the target and aim.
In actual combat, this method is not good. The better solution is to search for the target first, and then the artillery points to the target. The fire control system commands the artillery. This is the command ritual fire control system.
The aiming line of this fire control system is independently stable with a gyroscope, and the gunner looks outward from the aiming line and does not move to the background, so it is also called a stable image fire control system.
Now, if the country wants to develop new tanks in China, the fire control system is also a difficult problem to overcome. For a first-machine factory, it only needs to make requirements to the following supporting manufacturers, but this efficiency is very low. Now, our own tanks are developing,
Qin Zhenhua also paid attention to the issue of fire control system, and the team led by Professor Cao is one of the backbone forces in the research and development of this fire control system.
Of course, I have to try my best to help.
Although they are all called stable image fire control systems, there are also differences between upper and lower counters. For example, the sight follow-up system of the Leopard 2 main battle tank is stable with the upper reflector, with a large stable field of view and good optical performance, but for the device
The requirements are high. Based on the domestic situation, the first thing to overcome is the stabilization solution of the light mirror. The 120-degree prism in the gyro-directed stabilization scope is used. The structure is relatively simple, and the cost and cost are relatively low. Among them, the 120-degree prism is
, which is directly related to the quality of the entire fire control system.
Of course, the trans fire control system can only solve the problem of existence or not. This fire control system is simple in structure and has its disadvantages: when the artillery moves faster or the angle is larger, the error increases rapidly.
A disadvantage, in fierce battles, it will drag down the gunner's operation. Another important reason is that it cannot connect the night vision system images, that is, during night combat, the gunner can only retreat.
In the past, the steady-line mode, that is, the stabilization of the aiming line rather than the image, will greatly reduce the practicality.
There are two main schools of domestic optical equipment. Before the war, it was imported from Germany. After the war, it was mainly imported from the Soviet Union. After the war, the accuracy of the Soviet equipment has begun to deteriorate after years of use and cannot meet the needs.
When I was overcoming the difficulties in equipment manufacturing in China, I imported an urgent use from Germany, which was a small purpose for this trip abroad.
After all, Germany is still the first in optical equipment.
"Well, prisms and plane mirrors can be polished in anything." Qin Zhenhua said.
"So, what's the use of finding me? Just look for manufacturers. First-class manufacturers include Raul Company, Leica Company, and the equipment there is ready-made." Mia continued to ask.
