Chapter 544

Around and back again.

With the efforts of Qin Guan last year, the North heavy truck factory had advanced CNC machine tools and machining accuracy, which has reached the world advanced level. At the same time, it must be the most cutting-edge in China.

The fire control radar for processing plate gaps also needs the most cutting-edge processing technology. The breakthrough of airborne radar equipment in Han Dynasty is inseparable from the breakthrough in antenna processing technology.

When it comes to antenna processing technology, you have to mention a person, Zhang Gong.

Zhang Gong was born in 1938, an era of war. After that, he entered a famous university in the South and graduated from machinery manufacturing.

After graduation, he entered the 114 Research Institute of the Ministry of electronic industry. After the 11471 radar project was launched, she became the overall process director of 11471 mechanical fire control radar.

Her tasks are the technology of radar high-frequency components and the technology of mechanical fire control radar flat slot antenna.

Yes, it's her. She is a lesbian in her forties. She is at the most energetic time in her career. Now she is very excited after she comes into contact with advanced radar. The flat radar antenna has light weight and large radiation energy, which is the development direction of radar, and the problem of how to produce is left to her.

Planar slot radar antenna is an antenna formed by slotting on the conductor surface, also known as slotted antenna. The typical gap shape is a long strip with a length of about half a wavelength. The slot can be fed by a transmission line across its narrow edge, or by a waveguide or resonator. At this time, RF electromagnetic fields are excited on the gap and radiate electromagnetic waves into space.

Only half a wavelength is quite short. This processing technology must be improved, and there can be no burr!

In this way, Zhang Gong naturally thought of using CNC machine tools for processing. In this way, he immediately found the best CNC machine tools across the country.

As soon as I looked for it, I found the North heavy truck factory.

Now the North heavy truck factory has become a leading enterprise in the heavy truck industry. In the open space next to the factory, the phase II project is under construction in full swing, and the phase I plant is also operating at full power.

The number of workers has doubled. On the one hand, the factory starts to work day and night, and the 24-hour production line does not stop, so as to maximize the production capacity. On the other hand, it can also reserve workers for the factory in phase II. Once phase II is completed, it will be put into operation immediately.

Although there are North heavy truck factories and factories in old revolutionary base areas, the total output of those three factories is less than that of North heavy truck factory. At the same time, the reputation of North heavy truck factory has come out in the market.

We would rather wait a few months to place an order in the North heavy truck factory. Last year, even the deputy factory director of the North heavy truck factory was sued because of quality problems. With such strong efforts, the environment of the factory is quite good, there is no corruption and bribery, and the product quality is quite high.

Now, when Zhang Gong came here, it was such a scene that he had been stopped at the gate of the factory.

"I'm an engineer from institute 114. I want to come here for help. This is my letter of introduction." Zhang Gong said to the security guard at the door.

The security guard checked several times and looked at several people behind Zhang Gong.

Zhang Gong didn't come alone. Behind her, there were four young men carrying their luggage.

Generally speaking, the luggage is carried by everyone. It's a long way. They came by train. Now they all look very tired. But this luggage, like carrying a sedan chair, is carried over. It looks like a big box.

"I have to check your luggage," said the security guard. "This is our process."

What if it's an empty box when you go in and full of things when you come out?

In the factory, the biggest worry is theft. Many parts are valuable, some are aluminum and some are copper. If you steal one, you can pay a month's salary.

In this era, those factories with lax management, almost the workers of any factory, have such a method. They do it from top to bottom. Finally, the factory collapses and the workers lose their jobs.

The inspection here is very strict.

"No, what we have here is related to state secrets," Zhang said.

State secrets? If it's a state secret, why don't you even have a car? How many people are carrying it like this? State secrets, police cars have to open the way!

"If you don't allow inspection, you can't go in." the security guard is not wrong. He must strictly abide by the discipline of the factory.

Zhang Gong pushed his glasses. She knew that such a stalemate was not the way. When she came, 114 Institute originally planned to send a car to send them over. However, the journey was too far and the cost was too large. After all, the country was in transition. The funds of 114 key research institutes were also limited, so they came by train.

The railway station is very close to the factory. It's OK to walk, but now it's in a dilemma.

What should I do?

"Can you ask your factory director to come out?" Zhang continued.

If you want to avoid divulging state secrets, you can only invite the other party's factory director. The factory director should know, otherwise how can they process them?

"Our factory director manages everything every day. I'm afraid he doesn't have time like you," said the security guard.

Just as he was saying this, he heard a clattering sound in the distance, which was the unique roar of the high-pressure oil pump. Hearing this sound, the security guard was stunned: "you're lucky. Our factory director went out for a test drive and just came back."

Test run?

Inside the plant, there is a special testing ground, that is, the former tank testing ground. Now, it has been changed into a testing ground for ex factory heavy trucks. After each heavy truck goes offline, it needs to drive a few kilometers for testing, and then it can stop at the delivery area.

However, for a newly developed vehicle, in addition to repeated testing in the testing ground in the plant, it still needs to be tested out. Now, it is a newly developed vehicle.

Everyone was surprised when they saw the car. What kind of car is it? It's like lying on the ground!

In fact, it is very high, but it is wider than its height. In this way, it looks like lying on the ground. The tires of this kind of car are quite large, which brings a high ground clearance. It is even higher than the truck, with a large angle of approach angle and departure angle.

The roar came from its V8 diesel engine. At this time, several people in the car were shaking with the car.

This car is the second product developed by northern industrial company, Mengshi military off-road vehicle! This car is almost a perfect imitation of the Hummer.
