Everyone received the task from Jiang Yan, and after arranging the personnel, under the leadership of Jiang Yan, the design and manufacturing work was officially launched.

The first thing to do is the overall design of the whole vehicle. This protective car should be safe and comfortable in space, so the body size will be relatively large, expected to be 6 meters long, 2 meters wide, 2 meters high, the body, doors and windows, and floors are all made of bulletproof materials, with a thickness of 10 centimeters, which is enough to resist all kinds of small arms attacks, and even to a certain extent, it can resist the attack of small-caliber rocket artillery.

In order to be more resistant to mines and to be able to drive in poor road conditions, the chassis is higher than that of ordinary cars. The tires are bulletproof tires specially developed by Jiang Yan, which can ensure that the vehicle can run limited even if it is broken.

All the information of this tire has been sent to the hands of the big leaders by Jiang Yan's secretary, and they will coordinate the production of the tire factory.

In order to ensure the safety of communication, Jiang Yan also added a high-power walkie-talkie to the car, which can realize calls within ten kilometers, so that people outside can grasp the situation in the car at any time and increase the probability of rescue.

The engine compartment is also fully reinforced with special materials to prevent direct attack, and the surrounding area is wrapped with special materials, which has a fireproof effect to a certain extent.

In addition to the driver's room, Jiang Yan designed a small place to place an ambulance bag in the car, which can provide certain medical protection when injured.

"Just this paralyzed face, don't say it for ten years, you will still be able to recognize it in twenty years."

The fine tradition of the three great masters is inherited by the three mothers quite perfectly, no, at this time, the three mothers are sitting on a small stool at the gate while pasting matchboxes while observing the people who come and go.

"But thanks to our group of old disciples, step by step, we have finally completed the task!" Master Wang smiled arrogantly.

During the design and manufacturing, Jiang Yan repeatedly emphasized to the technicians according to the design drawings that they should achieve both safety and comfort.

The engine and chassis were also manufactured under the supervision of Jiang Yan, and the operation performance was good after testing, and it quickly passed the final acceptance work.

"Not really." Isn't this rain getting married? He Daqing said with a smile: "How can I, the father, not come back?" ”

After a day of verification, the basic performance of this protective car has indeed fully met the design indicators, and all the performance is excellent.

At this time, the big leaders and Minister Zhang who got the news also rushed to check the results.

On the twentieth day of the lunar month, there was a joyful atmosphere in the rolling mill.

Originally, He Yushui's wedding was scheduled for October 1, but Liu Yi had a very important task temporarily, and he couldn't coordinate the time, so it was postponed for two months.

After He Daqing said hello, he stepped directly into the courtyard and walked in the direction of his house.

Since today is Saturday, the country has not yet implemented weekends, and those who have work naturally go to work, and the rest of the people in the yard are basically women, elderly people and children.

Hearing He Daqing say this, the three mothers complained in their hearts.

Jiang Yan obviously does not have such conditions in their research institute, so they can only do some basic tests, for example, to test the spacious and comfortable space in the car, the operation of various equipment, walkie-talkie communication problems, and so on.

It was at this time that He Daqing returned to the courtyard with his own things, and the three mothers were stunned when they saw He Daqing, a little incredulous, and asked tentatively: "Are you... Is it He Daqing? ”

On the twenty-sixth day of the lunar month, He Daqing, who had been on the train for half a day, walked out of the Sijiucheng Railway Station with the flow of people.

"Haha, it's not hard, to see this thing, no matter how hard we work, it's worth it, and it's finally delivered before the year!"

This car requires a large number of relatively precise parts, so Master Wang Sandan is under the most pressure, but fortunately, he completed all the work within the stipulated time.

"My appearance hasn't changed much! It's just that this hair is a little grayer. ”

Through Jiang Yan's more detailed explanation, so that everyone understands the effect achieved by Jiang Yan in manufacturing this car, all departments quickly entered the production preparation stage.

As a result, they conducted a one-day comprehensive basic test of the protective vehicle. After a day of testing, the overall performance of the car is excellent, especially in the case of such a high load, it still runs at a speed that is not less than that of an ordinary car.

Jiang Yan looked at the black protective car parked in the workshop, and couldn't help but smile with relief.

"Little Jiang, how is the vehicle tested?" The two asked expectantly.

He Daqing had cerebral palsy, and a smile on his face that was not much better than crying opened his mouth and said: "Haha~ Brother and sister, why don't you know each other?" ”

Of course, if you want to be truly successful, you need more rigorous tests, such as car body protection ability, engine protection ability, tire protection ability, etc., all need to go to special sites for special tests, and after these tests are passed, the car can be finalized.

"Okay, let's do the final test today to make sure the indicators are up to standard." Jiang Yan said.

After days of intensive preparations, the production can finally be officially launched, and under the personal supervision of Jiang Yan, the production of protective vehicles is in full swing.

The twenty-eighth day of the lunar month was the day of He Yushui's wedding, so He Daqing returned to Sijiu City two days in advance to attend He Yushui's wedding, but no one told him the news of his return.

Jiang Yan personally participated in the selection and testing of materials, and selected them in strict accordance with bulletproof standards. For the bulletproof material, he applied various impact, explosion and other tests until he made sure that its protective performance was fully up to standard. For some key parts such as the engine compartment, Jiang Yan also designed a modular protective structure to improve the convenience of maintenance.

"It's good to be back, it's good to be back." The three mothers nodded.

。

After repeated tests, the protective capacity of the body fully meets the design requirements, and the light weapons cannot penetrate a single bit, and the engine and chassis are also manufactured under the supervision of Jiang Yan, and the operation performance is good after testing.

"Okay, okay" I'll arrange for a professional to conduct the test. Minister Zhang said excitedly.

"According to the report leader, the basic test of the vehicle was relatively successful, and the overall prediction was achieved, but if you want to carry out the production stage, you need to go through more rigorous testing of the system." Jiang Yan smiled.

"No, He Daqing, didn't you go to Baocheng? I heard that I was still married there, did I come back from a divorce? ”

"Yes, it's not easy to meet the protection performance standard." Jiang Yan nodded, "Installing internal equipment is a test of technology. ”

"What, brother and sister, you're busy here first, I still have to go home and have a look, see you later."

"It's not easy, and we've been all night several times!"

"Comrade, hard work! The car was finally completed a year ago!" Jiang Yan patted Master Wang Sandan on the shoulder and said.

Although he has often returned to Sijiu City in recent years, he has not returned to the courtyard once in a while, but he is still quite familiar with the road of the courtyard.

"It's broken, I forgot to tell He Daqing that their family moved." Not long after He Daqing left, the three mothers who came back to their senses patted their brains and spoke.

Just now, she forgot to tell He Daqing that the house in their house was changed with bangs, if she went in coldly, it would be a lot of fun, thinking that the three mothers here didn't dare to delay, and put the things in their hands into the house and ran to the backyard.
