The MiG-29 fighter, the third generation fighter of the Soviets, is a medium-sized aircraft, about the same size as the F-16, but it does not use a high-thrust engine like the F16, but uses two medium-sized engines, these two medium-sized engines, give the MiG-29 a strong thrust-to-weight ratio.

When he first went to the Soviet Union, Qin Feng had seen the MiG-29 with his own eyes, and when this kind of aircraft took off, the smoke coming out of the tail was impressive, and not only in the Soviet Union, the current MiG-29 has begun to appear at large-scale air shows, and every time it appears, the thick black smoke of the MiG-29 is the most criticized.

However, this does not hide the advanced nature of this engine, its smoke is only due to the use of a backward combustion chamber, which is also a principle of the Soviets, not too advanced, as long as it meets the needs.

This outstanding RD-33 turbofan engine was developed by the famous Klimov Design Bureau of the Soviet Union, with a two-shaft, low bypass ratio, and a unit structure with a total of 11 units. The maximum thrust of a single unit is 50 kN, and the afterburner thrust is 81.4 kN, which can be seen that the thrust of the F404 engine is about the same.

However, the other performance of this engine is worse, for example, the thrust-to-weight ratio of this engine, even in dry mass calculation, is only 7.87, according to the delivery quality of 6.62.

The thrust-to-weight ratio of the engine of the third-generation aircraft should ideally reach 8, but the level of the Soviets cannot do this, their weapon system has always been crude and heavy, in addition to the heavier engine, its life is also very problematic, compared to the F404's life of thousands of hours, the life of this engine is only a few hundred hours.

This is also caused by the different ideas of the two sides, Qin Feng secretly thought in his heart.

During this period of time, he got into the data room of the test flight institute between the test flights to study the data of the MiG-29, because this aircraft has begun to be exported to the outside, so it is not difficult to find its information, Qin Feng began to sigh a little after repeated research.

This is completely the result of the Soviet system, although the engine is stupid and coarse, but the work is stable, surge rarely occurs, and, even if it encounters air parking, there is no flight envelope restriction, you can restart at will, this kind of engine, is really a good and excellent engine, it is really suitable for your own side, you know, the domestic industry, has always inherited the Soviet model.

After relations with the West turned cold, relations with the Soviet Union began to ease, which is called the unpredictable world!

One day a few months later, Qin Feng finished flying a test flight subject, stepped off the plane, and saw a familiar figure.

"Old Song!" Qin Feng couldn't help shouting, in the blink of an eye, he hadn't returned to Chengdu for a long time, and he hadn't seen Song Lao, Qin Feng almost forgot that he was originally a test pilot reserved for Project 10, and he had always looked forward to the test flight of the J-10 fighter, but unfortunately, this plane was still on paper until now.

"Well, Qin Feng, it's a pleasure to see you, how does it feel about this plane?" Song Lao asked towards Qin Feng.

Qin Feng nodded: "Very good, the engine is stable, and the performance of the fighter is excellent, but this plane is too big, it can only fly steadily, and it can't do any maneuvering." ”

Song Lao nodded: "Although this is called a fighter-bomber, however, the main task is bombing, and if you want to use it as a fighter, it is impossible." ”

"Old Song, why do you have time to come here?" Qin Feng asked curiously, "You won't be looking for me, will you?" ”

The latter sentence is obviously full of doubts, he is a test pilot, if Song Lao comes to find him, is he going to start a test flight? That's too fast, right?

This must be impossible, he touched his nose, forget it, don't dream about it, Song Lao must have come for other things, just come by the way to see himself.

"You guessed it, I'm here this time, and it's really related to you." Song Lao said: "We have already reported to our superiors, our new J, will be a three-axis and four-degree fighter, and the previous control, completely different, in order to better grasp the essentials of the test flight, to prevent problems, so, we decided, send a few test pilots, to the United Kingdom, fly their stabilizer." ”

Go abroad to learn test pilots and communicate with foreign counterparts! Hearing Song Lao's words, Qin Feng was very happy, of course this is great!

When Shenyang was studying ACT technology, he fell on the plane, and the main reason was that the test pilots were not familiar with the operation mode of fly-by-wire.

"But it's going to cost a lot of money, right?" Qin Feng asked.

The country is not rich, and it is absolutely astronomical to go abroad to train test pilots, even if they fly at home, test pilots are quite valuable.

"You don't have to worry about that." Song Lao said: "This time I came, I was going to discuss with you, and a few other comrades, if you are willing to go, I will send you there, it's strange, I came here, I thought you would be entangled in the separation of the two people, who would have thought that you would be entangled in the problem of money first, this temper must have been learned from Lao Tu." ”

Tu Lao has begun to take the road of marketization, thinking about money everywhere, even if it is now cooperating with Grumman Company in the Super Seven project, the expenditure mainly comes from the initial 500,000 US dollars given by Pakistan, although he has gone abroad many times and used it for several years, but they are quite saving, so up to now, this money is still surplus.

Qin Feng also often runs with Tu Lao, and it is inevitable that he will be contaminated with this kind of thinking, whatever happens, the first thing that comes to mind is money.

Hearing Song Lao's words, Qin Feng's eyes suddenly dimmed.

Yes, at such a time, I left my family behind again.

Once there is a task, Qin Feng always wants to be the first to go, but when the task is issued and he has to be separated from his family, he will think of Tingting's difficulty, and only then will he think of the loneliness of Xiaohutou, during this time, with his lover and children, Qin Feng feels quite happy, Tingting is also very happy, and she walks with a small tune.

He really hoped that this life could continue, who would have thought that after only a few months, they would be separated again?

How do you talk to Little Tiger Head? I promised the little tiger head, and I want to be an incompetent father again!

Qin Feng's expression was seen by Song Lao, and Song Lao smiled: "Now, we are still in contact, and it may take a while to go out specifically, after all, the current environment is not too good." ”
