It is not a simple matter to change the engine of a different type of aircraft to an aircraft, whether the engine is installed in the right way, whether the air intake tract is matched, and whether the control system can play to the level it should be? These are all tests of the technical level of aircraft designers.

At the beginning of the project and design, the J-10 was based on the TF41 engine, which is the largest thrust turbofan engine that can be used in China, and the technology is mature.

It's just that the TF41 engine is a modification of Spey, which is almost the ultimate model, and if you want to continue to improve, it will reach 110,000 Nn at most, and in terms of performance, it can't be compared with the F110 engine of the new core machine.

This is also the reason why Pakistan has done everything possible to obtain the technology of the F110 engine, which is the only engine that can support the future Pakistani sky.

Replacing TF41 with F110 seems to be just an idea, and if you want to put it into practice, you must have a lot of work to do, and it can't be completed in two or three years.

However, those present knew that all this was not difficult, because the F110 was designed to be interchangeable with the Tomcat's engine! The position of various receivers and accessories is the same, and it is very convenient to interchange. The design of the air intake can also accommodate two types of fighters.

When Yang Wei and Pakistan jointly developed the flight control of the Tomcat fighter, he already knew the various performances of the F110 well, and the engine was also fly-by-wire, which required the cooperation of the software in the flight controller. Therefore, whether the No. 10 machine can install the F110 depends on whether Yang Wei can rewrite the program that controls the F110 in the flight control software of the No. 10 machine. Join in.

Yang Wei is fully confident, if he installs the F110, he is 100% sure.

Now, Mr. Song has made a decision, and the work that Yang Wei needs to do is to contact the Pakistani side. Ask the other side to provide an F110 engine to be installed in their No. 004 aircraft to prepare for the confrontation drill with the F-16.

At this time, it was already April, and sitting on the train, Song Lao and Tu Lao were in a heavy mood.

If they were to engage in an aerial confrontation, they would be able to achieve absolute superiority, but now the most important thing is to do so. It is to convince the superiors to let them conduct a confrontation exercise!

It's a heavy task, but it must be done.

In the shaking of the train, the two came to the capital, which was already very lively at this time.

Although the two are the general directors of Cheng Fei, they are now impacted by the economic tide. There has been a phenomenon in society that it is better to sell tea and eggs than to engage in an atomic bomb, and Cheng Fei's salary is not high. Many people went to the sea to do business, and they all made a fortune quickly. Now, the driving force that can mobilize all of Chengfei together, give up material needs together, and engage in scientific research day and night is the No. 10 machine! This is a fighter plane that has pinned the dreams of countless aviation people. If this model is abandoned, then Cheng Fei is afraid that it will decline completely, and many of these hard-hit development teams, many of them, are afraid that they will go to society. Do you want to realize your value in another circle?

And every time the two of them go on a business trip, they don't dare to break the bank, and the scientific research funds are limited, so they must invest the limited funds in the development of fighters! So, now the two of them take the train first, then the bus, and come to the third machine department.

(The entire development of the No. 10 machine cost no more than 10 billion yuan, compared to a courtesy car of FAW, which cost tens of billions of dollars to develop, and the difficulty of developing a car is much higher than that of an airplane?) ）

Entering the gate of the Third Machine Department, looking at the front wall, there are a few big words written on the front of the people, Song Lao felt depressed, serving the people, this is definitely not an empty word, but to take real action, not to fight for power and profit for himself, but for the whole country, for the people!

"Minister, here we go again." Song Lao and Tu Lao, who had come all the way over, saw the minister of the Third Machine Department, put on a smiling face, and said to each other.

"Or for the grants, right? The chairman has agreed, and now our focus is on the introduction of the F-16 fighter project, and the allocation of Chengfei needs to be pressed backwards for the time being. The minister said.

Prepared? If you want to get yourself to give up this project, no way! Song Lao said: "Minister, we are not here this time to ask for appropriations, but to issue a war letter. ”

In an instant, the backs of Tu Lao and Song Lao both straightened, this time they came to challenge!

"War letters? What war book? The minister asked, "Sit, sit down." ”

"Yes, it's the war book." Tu Lao said: "We want to have an aerial confrontation, using our No. 10 aircraft, to confront the F-16!" ”

The smile on the minister's face froze suddenly: "You use the tenth machine to fight? Not okay? The No. 10 aircraft has not yet been finalized, there are all kinds of problems, such an aircraft, not to mention combat, even take-off and landing, are full of all kinds of unknown risks, so forget it. ”

"No, we have developed our own fighters, and we know in our hearts that all our performance is completely suppressed by the F-16!" Song Lao said: "We only want a confrontation exercise to confirm the excellent performance of our fighters!" If we fail, we willingly stop Project 10! If we win, it means that the performance of our fighters will surpass that of the F-16! ”

Song Lao's words were loud, and the minister of the Third Machine Department frowned slightly, followed Shu, and said: "Okay, since you have this kind of confidence, we can consider it, you better go back first, we need to discuss this matter and make a decision." ”

Coming out of the Third Machine Department, the expression on Song Lao's face was still solemn, and he said to Tu Lao: "Old Tu, although the Third Machine Department has won against us, but the answer is ambiguous, I think, maybe it is just perfunctory to us, even if it drags on for a few months, and when the assessment is over, it will be difficult to deal with it if it really pays the United States." ”

"yes, I'm worried about that, too, maybe the Third Machine Department will really do this." Tu Lao said: "We have to think of something else. ”

"Look, how about we go to the commander of the Air Force?" Song Lao said suddenly.

Commander of the Air Force! You know, the first object of equipment for these fighters is the Air Force, followed by naval aviation, after all, the Air Force is the user, although the current system has decided what aircraft the aircraft factory produces, and the Air Force will equip it, but, after all, the Air Force still has a certain right to speak, if the Air Force does not look down on the F-16 and repeatedly reiterates its position to the chairman, the chairman will consider it.

Cheng Fei, the relationship with the Air Force is quite harmonious, Cheng Fei produced the J-7 fighter, the Air Force is more welcome, in contrast, Shen Fei produced J-8, frequent failures, Leng does not admit that it is a design problem, is the pilot's flight action problems, until there is an accident, I have to admit it, pull back to improve.

"Let's go, let's go to General Wang, the commander of the Air Force!" Tu Lao said.

At this time, the commander of the Air Force is still Wang Hai, an old pilot who once shot down four enemy planes and damaged five on the Korean battlefield! Such a person is very upright, attaches more importance to equipment, and will not have a bureaucratic style! Moreover, General Wang visited Chengfei several times to inspect and attached great importance to the leadership of Project No. 10.

"Let's go!" With the belief in the persistence of Project 10, the two went to the Air Force Command.

At this time, it was already afternoon, and the two got off the train, and they hadn't eaten much, so they could only nibble on the steamed buns brought by them on the bus, drink a few sips of water in the glass glass, and look at the building, where the Air Force Headquarters arrived.

In the past few days, the fatigue of the journey has made their spirits a little sluggish, after all, both of them are already over sixty years old, but they still have to run for the No. 10 project.

After getting out of the car, the guards at the door saw the two of them, looked at the documents, and immediately let them go.

"General Wang, the two of us are coming to you with a thick old face." Seeing Wang Hai, Tu Lao said with self-deprecation.

The three of them are about the same age, Wang Hai's hair is already a little white, looking at the two of them, Wang Hai said: "Lao Tu, Lao Song, you are still for the matter of Project 10, right?" I've already reported to my superiors, but the report has been suppressed. ”

Wang Hai is very concerned about the No. 10 project, after all, Huaxia needs a self-developed fighter too much, and it can buy all kinds of advanced fighters, but it definitely can't buy the strength of the Air Force!

However, only his support is not enough, the performance of the American F-16 fighter is indeed good, it has participated in many wars, and the performance of this fighter has been tested, and Huaxia's self-developed No. 10 project, everything is still unknown, so the call for support for F-16 is also very high.

"yes." Song Lao said: "General Wang, our current fighter development has entered the test flight stage, and all kinds of problems exposed by the test flight have been improved, this fighter is an excellent fighter, and its performance is definitely above the F-16, and it is on the F-16/79 that we are about to introduce." So, now we want to speak with facts, hold a confrontation exercise, and in the confrontation, defeat the F-16! ”

General Wang's eyes suddenly lit up: "Your plane is still in test flight, and now you can conduct a confrontation drill with the F-16?" ”

"Yes!" Song Lao said loudly: "We are confident! ”

"Okay, since you have confidence, I will report to my superiors, and within us, we will first conduct a confrontation exercise to see if the Americans' F-16s are more advanced than the fighters we have built!" General Wang said.

With the impetus of the Air Force, it is impossible for even the Third Aircraft Department to come out and obstruct this confrontation exercise! (To be continued......)
