Rebirth of Military Workers

Chapter 252

Missile engines are fundamentally different from aero engines.

Even if the missile engine withstands higher temperatures during operation than an aero engine, during use, even for an intercontinental strategic missile, the operating time is only half an hour and less than an hour. At the same time, in order to reduce the weight, it is divided into several levels. The propellant of the first stage will be separated after burning, and the engine of the next stage will ignite.

As a result, the service life requirements of the engine are reduced a lot.

Aero-engines are different. They require the engine to work repeatedly, withstanding ultra-high pressure and ultra-high temperature working conditions for a long time, and must have longer durability and higher reliability in such working conditions.

The requirements of civil aviation engines in this regard are even more demanding than military engines.

In a high-temperature and high-pressure environment, the materials fail to pass, and the production process does not pass, the engine produced will not reach the service life.

This is the case with the turbofan eight that is used in the YXT. Even after various tests, it dare not be used for long-term flight.

“What if we want to produce larger missiles?” Zheng Yucheng asked.

“It is not appropriate to discuss this issue at this time.” Xie Kai looked at the people around him and said to Zheng Yucheng.

Zheng Yucheng also woke up.

They went to West Air to understand the status of the imitation work of the bass engine. According to the current situation, if a breakthrough cannot be made, it will be very difficult for them to use domestically-made engines for the fighters they cooperated with the Iraqis.

If you can’t use a domestic engine, you can only wait.

Or, think of a way to get engines from abroad.

Military turbofan engines with high thrust are all embargoed on China internationally.

It will take a few years for Iraqis to be sanctioned by the United States and other brothers in the world. At that time, it will become more difficult to introduce them.

“If your needs are urgent, we can help purchase from the British Rolls-Royce Company…” Tian Rui said to several people when he left.

They are also helpless.

Everyone wants to be able to produce it now.

“Let’s think about it again. After all, it is only a cooperation intention. The specific design and engine required are not completely determined yet.” Zheng Yucheng said.

The horoscope hasn’t been swiped yet.

“Do you really want to engage in fighter planes?” Du Shengfeng asked Zheng Yucheng on the way back. “What the hell does 404 do? It seems that you can intervene in any project!”

“As long as the project is to make money, we all want to do it.” Zheng Yucheng said with a smile.

But they were distressed in their hearts. At West Air, they understood in their hearts how difficult it is to get involved in the fighter jet project.

Everyone has said that there is no shortage of money, which means that it is impossible to count on money to get technology out.

Like a large press, at least it can be produced, and there will be no problem as soon as the funds are in place.

Aero engines are not good.

“Director Du, in the forging equipment production base, I guess you have to arbitrarily support a powder metallurgy manufacturing unit.” Xie Kai said to Du Shengfeng, “Otherwise, our raw materials will not be supplied by a unit.”

“Didn’t West Air and other departments have it?” Du Shengfeng didn’t understand.

Zheng Yucheng knows Xie Kai’s thoughts, “Xie Xie means that a complete industrial chain is formed in the base. From the upper material processing to the subsequent mechanical processing, try to complete the base or the surrounding area.”

Centralized supporting facilities will save a lot of money.

“This has to be communicated with the Materials Research Institute and other units.” As soon as Du Shengfeng said that this matter could not be the master, he had to communicate with other units, which made Zheng Yucheng very dissatisfied.

“Let’s not worry, we can always think of a way.” Zheng Yucheng saw Xie Kai worry and comforted him.

Xie Kai smiled bitterly, “What am I worried about?”(Read more @ wuxiax.com)

Du Shengfeng looked at the two of them and didn’t understand what they meant.

When the group left West Air, they went directly to Qin Fei.

The forging base will be built next to Qin Fei, which is also a plain area. It is more appropriate to build a forging base.

“Director Zheng, are you here?” Ma Fengshan came to greet a few people in person.

“Mr. Ma, aren’t you on Erzhong’s side?” Xie Kai is curious, isn’t Ma Fengshan doing the big press in Erzhong?

When did you come back?

“The institute is organizing the relocation here. The first batch of personnel will come in a few days. Everything must be prepared.” Ma Fengshan explained, “Xiaocheng is over there, so there will be no problems.”

“When will the comrades from the institute come?” Zheng Yucheng asked.

“I will get on the train over there tonight.”

“Mr. Ma, to what extent has our Y-10 prototype been assembled?” Xie Kai was worried about the condition of the aircraft in the workshop of the 5703 factory.

The domestic cooperation with McDonnell Douglas will be signed in May.

After signing the contract, McDonnell Douglas will start to work on the 5703 factory. They must assemble their prototype before this time, and they must also complete ground testing so that the aircraft can fly from Shanghai to Qinfei. Inside the airport.

“I’m working overtime to assemble. It should be possible to complete the assembly by the end of May.” Ma Fengshan looked at Xie Kai and didn’t understand how he asked this now. He reported to Zheng Yucheng a year ago.

“Can the assembly be completed before May? You must have the ability to take off!” Xie Kai was a little anxious. “The cooperation between McDonnell Douglas and the country is now at the final stage of negotiations. If nothing happens, a cooperation agreement may be reached in May. The two sides have talked for too much time.”

“So fast?” Zheng Yucheng looked worried.

When McDonnell Douglas came in, it was absolutely unkind.

“I haven’t heard, but during the period before the New Year, the leaders of the 5703 factory and the supervisors of the Shanghai stock market took a long time to go to the capital. The people from McDonnell Douglas visited the assembly plant again.” Ma Fengshan also wrinkled. Frowned.

“Why, what’s the contradiction between you and McDonnell Douglas?” Du Shengfeng listened confused.

What does McDonnell do?

“The contradiction is gone, you can say that you don’t share the sky!” Zheng Yucheng said bitterly, “If it weren’t for them, why would we have to borrow Qin Fei’s assembly workshop and workshop?”

“What does McDonnell Douglas do?” Du Shengfeng really didn’t know McDonnell Douglas.

“Macdonald Douglas Aircraft Manufacturing Company, they have come in, and they are transporting ten to make room for them…” Xie Kai briefly explained to Du Shengfeng.

He didn’t explain to him because Du Shengfeng was a leading cadre, but had a purpose.

“Director Du, what’s your relationship with the railway system?” Xie Kai’s question spans too wide, and for a while, several people are a little confused about his purpose.

“It’s okay. If you want to transport something, there is no problem with several freight train batches. If it is wagons, it is better to say, all over the country, as long as the train can arrive, you can speak.” Du Shengfeng boast.

As the director of the National Defense Science, Technology and Industry Commission in charge of a region, he must have a good relationship with the railway system. After all, many military materials need to be transported by rail.

“Do you want to move all the related equipment of Yunshi before McDonnell Douglas comes in?” Zheng Yucheng understood the purpose of Xie Kai.

Ma Fengshan couldn’t comment on this matter.

“Move the factory?” Du Shengfeng asked.

“Yes, the Yunshi production line and the equipment in the 5703 factory are all invested by the state. Many of Yunshi’s supporting equipment are dedicated to such large aircraft as Yunshi, and Qin Fei does not have it here. New Yunshi will be assembled later. Ten, or replace the key parts of the previous prototype, which needs to be re-produced…” Xie Kai nodded and said.

The Yunshi production line cannot be used for McDonnell Douglas production at all.

McDonnell Douglas came in, and the fate of these production lines was to be abandoned, piled aside and rusted or something.

“If you do this, will something happen?” Ma Fengshan was a little worried.

“Mr. Ma, you should be clear that once they both sign the contract, everything in the 5703 factory will belong to the new joint venture company! When the contract is not signed, it belongs to the Yunshi project. We relocate and no one can say anything ! Of course, no one knows better.” Xie Kai said.

From the very beginning, I was going to leave an empty shell for McDonnell Douglas. Xie Kai didn’t think this thing would be unnatural.

McDonnell Douglas had no peace of mind when he came in. If they came to help China develop the civil aviation industry, they would probably not believe it.

“You will be ready at that time. When will the train need it, call me three days in advance.” Du Shengfeng licked his lips and said to Xie Kai and Zheng Yucheng, “Is the equipment moved here?”

Xie Kai looked at him with a weird face, feeling that this guy helped out because of this.

“Do we have other places to put those equipment? The first Yunshi has been grounded…” Xie Kai sighed.

Ma Fengshan on one side also looked embarrassed.

With sufficient funds, Yunshi dare not fly casually. Now, every time it flies, a more comprehensive and detailed inspection must be made to ensure that the aircraft will not disintegrate at an altitude of 10,000 meters during the next flight.

“This thing is really arrogant.” Zheng Yucheng said.

Ma Fengshan saw that they both stared at him, “Speed ​​up, the assembly will be completed by the end of March, and the ground test can be completed within 20 days, as long as there are no major problems…”

“When the assembly is completed, some equipment that is no longer needed is ready to be packaged and transported gradually. Mr. Ma, the leaders of the 5703 factory, have to rely on you to say hello to them…” Xie Kai said.

“I’ll find a time for this matter. After all, it’s not a trivial matter.” Seeing Ma Fengshan’s embarrassment, Zheng Yucheng took the initiative to take the matter over.

He is best at doing this kind of cheating and self-interest.

“This matter needs to be kept low-key.” Xie Kai reminded Zheng Yucheng.

Evacuate the 5703 factory and take away a group of skilled workers. Once these things are discovered, they will definitely cause great disturbances.

“In the early days, we can get skilled workers here first.” Zheng Yucheng said, “Assemble a transport ten, not many people. Gradually, workers resign and go to the sea. No one can stop it? It’s not easy to get caught. Find……”
