(Although the gourd is no longer anti-theft, but I hope that the ability is still subscribed, after not anti-theft, the subscription does drop greatly, and it will not be anti-theft in the future, but the subscription is low, it is definitely impossible to have too much power code words, not to mention the explosion.) ）

"If you want to build it, you have to build a larger, complete and well-equipped engine production plant! This is an aircraft engine, not the kind of small motorcycle engine that Factory 132 matched to Jialing Factory...... "The Management Committee of the Ninth Academy has more enthusiasm than Liu Yijiu imagined in this matter.

Wang Shunyi and others very much hope to be able to build a good power plant by themselves.

"The original Air Force No. 4 Station Factory, now only produces some supporting airport sweepers, nitrogen-filled vehicles, etc., for us, there is no need to make a factory at the beginning, just put it directly on the 541 base, it is really not possible to integrate into the workshop, and the area around that area is also ......large."

Wang Yueshan is very concerned about being able to set up a power workshop outside.

In this way, a group of people from the mountains can be migrated.

At the same time, in the mountains, although all kinds of supporting facilities are perfect, it is not as convenient as in the city, especially the narrow terrain in the mountains, which cannot meet their development at all. Helicopter assembly requires a huge area, and the manufacture of power equipment also requires a huge area.

"Not only aero engines, but also gas turbines can be produced on our side, of course, this matter is best cooperated with Dongqi...... Liu Yijiu's ambition is obviously not small.

republic for decades to come, coal power. Natural gas power plants, oil power plants are very numerous.

A huge number of gas turbines are required.

"That's fine, that's it. Comrade Wang Yueshan will be responsible for the matter. Xiao Liu is still mainly focused on the production of turbofan-8, and he must get this engine out in one go, formulate a perfect production process, and inspect it in the production process. Whether the republic's new generation of fighters can soar in the air depends on this engine project...... "Long Yaohua is also here.

The military was very concerned about the turbofan-8 that had already come out.

Especially in the third-generation advanced fighter Panda F-14, which imitates the US imperialists, is working smoothly, but the engine has become a big problem, how can we not let them get angry in a hurry?

Even the Air Force of the Republic could not procure much. At the very least, it has to be able to produce it.

The current J-8 II and J-7 have too small combat radius and too small bomb load.

"There's no problem with that. After all, we have experience in producing turboshaft engines and other things. "Zone 1 is already in charge of power and helicopter technology. Originally, the entire Ninth Academy did not have the technical reserves of fighter jets or other aircraft, because the third-line factory had established several aircraft factories in the Qinling Mountains and the Rongcheng Plain.

Liu Yijiu didn't pay attention to these things, and once again put his energy into the production of engines.

Now production is very critical, whether it can solve these problems. It is related to whether the imitation Panda fighter can fly into the sky. It is even more related to the success of the first domestically produced third-generation fighter -- the Jian-10.

Nothing else is a problem, although the large use of titanium alloy has increased a lot of costs, processing is also a huge difficulty, and now we are working to solve these problems.

The construction of the power plant will make the research work of the Ninth Academy and even the whole of China in power technology faster.

From the very beginning, high-temperature and high-pressure powder metallurgy manufactures the blanks of various components of the engine, and then to forging, heat treatment, and machining. Director Liu can be seen at all times in various processes, dealing with front-line technicians and grassroots workers. Liu Yijiu learned a lot of things.

Originally, he would have thought that the problem of the turbofan-8 engine would appear in the assembly process, after all, in order to ensure the performance of the entire engine, it is necessary to ensure the assembly accuracy, and the 21-level fan impeller must ensure that the coaxiality is within 0.001 after assembly. This places higher demands on the assembly process.

What's more, the current assembly is mainly manual assembly, and automated mechanical equipment does not have much effect in the assembly work at all.

In order to ensure the accuracy, the Ninth Institute and the 132 factory have mobilized the top eighth-level and nine-level fitters, even if the 21-level fan impeller cannot reach the accuracy of 0.001 mm after assembly, at least it cannot exceed 0.005 mm, otherwise, the performance and service life of the engine will be affected, how serious, I don't know for the time being.

However, what Liu Yijiu didn't expect was that before the assembly process arrived, there was a problem again.

The welding of the impeller, as well as the welding of other parts of the engine, there is simply no way to guarantee consistent quality!

"Director Liu, it's not that we don't work hard, we use the same tooling and the same method every day, but the quality of the welds processed is inconsistent...... "Huang Ying, as the most skilled person in the entire welder, she can't control the processing quality of the weld.

"Is there an analysis of the problem?" Liu Yijiu asked with a frown.

Since the start of the last selection, welding in the pressurized cabin has started directly.

In the past few days of welding, there are more parts of the welds for comparison, so that the people inside have found that although these welds are much better than the quality of argon arc welding outside, but for the quality supervision personnel, it is simply not enough.

They wanted to be able to achieve a more consistent quality and thus determine the manufacturing process.

"According to our analysis, the main problem may be that the purity of argon is not enough......," Qi Hai said with some embarrassment.

"The purity of argon is not enough, so let them improve the purity, you can't let me solve everything, can you?" Liu Yijiu's brows furrowed even tighter. "Is there something wrong with it?"

"Director Zheng said that their technical level is ...... like this"

Liu Yijiu rolled his eyes when he heard this.

What does Zheng Hao want to do now?

Didn't he just not agree to let him continue to expand production?

"We can't do anything about this problem, we don't have too strong technical capabilities, and argon is originally a by-product of the production of oxygen, and it is not too easy to extract...... Zheng Hao also has difficulties.

Liu Yijiu glanced at him, "I don't care so much about you, anyway, no matter what the inside story of this matter is, or what difficulties there are, I will mention it to me in the future, I must improve the purity problem within a week, even if the cost increases, there is no problem!" ”

High purity argon gas can ensure high-quality welds.

"Maybe there's a problem with your pressurized chamber!" Zheng Hao said dissatisfiedly.

But this reminded Liu Yijiu.

When the work compartment was filled with argon, the air inside was not exhausted, and the workers waited outside the pressurized chamber, but the air was also not exhausted. At the same time, some of the exhaust gases generated by the high temperature during the welding of the material are also in the pressurized chamber.

"We must detect the change in the density of argon in the cabin, and at the same time, we have to find a way to extract the argon in it every once in a while for purification, otherwise, the quality problem will not be solved at all!" Zheng Hao's complaint was originally unintentional, but Liu Yijiu remembered it.

After checking the quality of argon in the pressurized chamber and the working chamber, it was found that the purity of argon gas, which was not pure enough, was even worse.

"The purity of argon produced in the oxygen production workshop of the four station factories must reach 99.99%, and the purity of argon in the working cabin must be guaranteed to be 99.9......%.

After replacing the high-purity argon, while ensuring the purity of the argon inside, the effect is obvious at once, and the welded weld can at least ensure that the weld welded by each worker is consistent.

After solving these problems, Liu Yijiu once again put his energy into the assembly of the engine.

The problems of the processing process cannot be solved in a short period of time.

When the technical strength has not been improved, the experience has not been accumulated enough, and the development of material technology is not in place, it is absolutely impossible to develop a machining tool that can improve efficiency in a very short period of time.

In the current situation, it can only take time to slowly pile up these parts and products.

Even the United States and the Soviet Union, which have strong processing capabilities, are helpless in the face of difficult-to-process materials such as titanium alloys, otherwise the United States imperialists will not finally let the F-15 and F-16 and F-18 replace the F-14, and the F-14 with a large number of titanium alloys not only has high maintenance requirements, but also increases too much processing costs.

The 80 F-14s sold by US imperialism to Iran were sold for $80 million!

Although, the cost of production will be much lower.

The manufacturing cost of an F-14 must be at least more than 30 million US dollars, or even higher!

Su-27, the performance is actually not as good as the F-15 and F16, but the manufacturing cost of each aircraft is more than 23 million US dollars, and the export price is 33 million US dollars.

It is not an easy task to produce a fighter.

Now producing an engine makes Liu Yijiu feel big.

Compared with their era of advanced technology and strong manufacturing capabilities, there is no need to think about these problems at all.

Especially the current assembly, it is even more head-catching.

The turbofan-8 has a low service life when it is tested on the air platform, and another reason is that the assembly of the engine cannot achieve accuracy, and the detection means are not up to par!

Liu Yijiu also discovered the problem after going deep into these tasks.

If we do not solve the problem that the assembly accuracy cannot be guaranteed, and do not solve the problem of testing the assembled engine, the turbofan-8, even if it is manufactured, cannot reach a service life of 500 hours, and it can exceed a hundred hours, which is a miracle.
