Donald's help to the 132 factory, is quite moved, if there is no 132 factory, the current 011 base, I am afraid it will have to be abandoned, tens of thousands of workers, I am afraid they will have to be laid off, and look for a new way out again, now, we have a new project, is on this project, just struggle, and strive to complete the key project at hand as soon as possible!

Looking at the wing of this J-7III, Qin Feng was also excited, at the beginning, Qin Feng participated in the introduction of the MiG-21MF together, and in Egypt, he also became good friends with Mustafa, and now, so much time has passed, this aircraft codenamed J-7III, there is still no follow-up.

Now, will the troops look at the J-7III again?

It is estimated that it is enough to choke, the domestic aviation industry, is also in continuous development, the J-7 M developed by their own side, has been selected by the Air Force, the Air Force has also ordered a batch, and now, the new J-7 CP project, has also won the attention of the Air Force and the Navy Department, this aircraft, even if it is manufactured, I am afraid it will face a backward situation.

"Why hasn't our current J-7III started its test flight yet?" Qin Feng couldn't help but ask.

Hearing Qin Feng's question, Donald's face was also helpless: "The main reason is that our engine, the mapping and mapping imitation turbojet-13, has not been going smoothly and cannot reach the delivery state, so since there is no qualified engine, the final assembly of the aircraft is hopeless, in fact, the Air Force has placed a batch of orders, and we have produced these parts according to the order, but there is no follow-up, we are waiting for the engine to be hungry." ”

"Isn't our Turbojet-7 already mature?" Qin Feng hadn't paid attention to this aircraft recently, and now he couldn't help but feel a little strange when he heard Tang Lao talk about the engine.

To be precise, the turbojet-13 is not directly related to the turbojet-7, the turbojet-13 is a completely mapped imitation of the MiG-21MF engine, however, this engine is still improved from the previous model, the biggest feature is to change the compressor.

The compressor improves the intake flow rate and increases the total pressurization ratio, so that more air can be poured in the back, and more oil can be burned, and the natural power will be greater.

The high-pressure compressor has been increased by 2 stages, the pressure ratio has been increased to 9, and at the same time, in order to reduce the weight, a large number of titanium alloys are used to make the blades of the compressor, and there are many improvements in the combustion chamber and so on.

Because there is no experience in China, we can only completely copy the cat and draw the tiger, and carry out surveying and mapping imitation, and in the imitation of the engine, we have encountered many technological problems.

Tang Lao knew very well that this engine was copied by surveying and mapping at the Liyang Factory in Guizhou.

"If you want to know, I can take you to the Liyang factory to have a look." Donald said.

In the 011 base, there is also a special aero engine manufacturing enterprise, which is the Liyang plant, the internal number of the 460 factory, and the 410 factory in Shenyang, which is the main factory for the production of turbojet engines.

The mapping of this engine was mainly handed over to the 460 factory, and now, the progress is only known internally.

Qin Feng had been to the 410 factory before, and the 410 factory at that time was developing the turbofan six, but unfortunately, after the project was announced to be finalized and tested, it was discontinued.

"By the way, is the imitation of the Turbojet-15 also in our 460 factory?" Qin Feng asked.

The engine of the new J-15 is intended to be solved by using the turbojet-15, and in the era when the Western world has begun to make great strides towards the turbofan, the other side is still using the backward turbojet, which is also helpless.

However, now it seems that the situation is not good, a simple turbojet-13, it has been used for three or four years, and it still hasn't been made, so what about the completely different turbojet-15? Can this turbojet engine be imitated?

It's really a question mark, if this engine can't be made, it means that your new fighter will face serious heart problems.

As a test pilot who joined in the design stage of the new J, Qin Feng was quite concerned about this aircraft, so Qin Feng nodded: "Okay, anyway, the current aircraft has not completed all the assembly, take time, I can go to Factory 460 first to see how our engine is." ”

Aero engines are the laurels of industry, and being able to produce aero engines is a sign of a great power, especially turbofan engines, which have complex technology and must have sufficient industrial strength if they want to get out.

Even if all the design drawings are placed in front of you, there is no processing technology, no process, and it will never be produced.

Qin Feng knows this, even if it is an American, when he is engaged in the F100, he also falls on his heels, this kind of engine has been equipped with troops for several years, and it has been grounded in a large area because of technical problems.

Heart problems, I don't know how long it will take to solve them in China! Qin Feng thought to himself in his heart.

After going around the whole factory, it was time for dinner, after dinner, I fell asleep, and the next day, Qin Feng asked to go to Factory 460 to have a look.

Originally, I planned to assemble it with my comrades, but looking at the enthusiasm of the engine factory, Qin Feng still didn't stop.

The 212 was finally repaired, and today's Qin Feng took the car specially prepared for him in the factory and went to the 460 factory.

Although they are all in Guizhou, the area of Guizhou is still very large, especially in the mountainous areas, the road is difficult to walk, and it was not until the afternoon that Qin Feng finally entered the gate of the 460 factory.

When Qin Feng walked into the door, unexpectedly, he saw another team of people coming over, and when he saw that familiar face, he couldn't help but shout: "Old Song! ”

"Hey, why are you here?" Song Lao was also very strange, all the way over, the journey was tiring, his eyes were a little bloodshot, revealing a surprised expression.

"I'm here to fly Jianjiao VII, and I heard that the mapping and imitation of the Turbojet-13 here has not yet been completed, so I came over to take a look, why are you here?"

Qin Feng is also very strange, why is Old Song here?

"Like you, in addition to the Turbojet-13, there is also the Turbojet-15." Song Lao said: "It's just right, let's go in together." ”

Song Lao looked preoccupied, Qin Feng said to Song Lao as he walked: "I've gone to see, the wings made for us here have all come out, but because there is no turbojet-13 engine, the J-7III has just stopped." ”

Song Lao nodded, in his hand, the J-7III was the first model to go through the entire process, but it ended up stuck on the engine, otherwise, it would have been able to make its first flight last year, or even the year before last!

With the change of the situation, the prospect of this aircraft has gradually dimmed, fortunately, they have obtained the research and development authorization of the No. 10 project, and the comrades of the 611 Institute are now working hard to get this new project down.

It's just that the imitation of the turbojet-13 is full of difficulties, and this turbojet-15 is probably even more difficult.
