The time has entered 1998, and with the continuous development of the test flight project, the first flight is just around the corner.

Early in the morning, Song Lao walked slowly in the direction of the conference room along the familiar path, and when he passed by the training equipment venue, he saw several test pilots doing their daily routine training there.

As a test pilot, you must keep training to make your physical fitness reach the most standard state in order to meet various challenges in flight.

Now, it is Qin Feng who is constantly rolling, Qin Feng has never relaxed his physical training over the years, and now, after completing three sets of training, he came down from above and saw Song Lao.

"Old Song, come and try?" Qin Feng asked with a smile.

Song Lao hurriedly shook his head, I can't stand this thing, in the early years of the development of the aircraft, the engineer was the test pilot, but with the continuous development of flight technology, the engineer's body is absolutely unable to stand the overload of the aircraft, and a special test pilot is required.

Qin Feng wiped his sweat with a towel, and then jogged all the way, following Song Lao, Song Lao looked at the runway in the distance while walking, and said, "Do you know the situation in Shenyang?" ”

"Over there in Shenyang? You know, if nothing else, they should be able to roll off the assembly line this year with the first localized J-11 fighter, right? ”

The experience of buying the Su-27 for the first time is still vivid, and the first batch of 24 Su-27 was finally bought, because of insufficient funds, it was still bartered, but the second batch of 24 purchases, the country's pockets have been bulging, all settled in foreign exchange, and in recent years, the country's economic development has been quite rapid.

After the completion of the second batch of purchases, the country began to discuss the introduction of technology production, at the beginning, Russia was not willing to continue to sell the whole machine, but the domestic attitude is very resolute, that is, to buy the production line, their own production.

After a series of negotiations, Russia finally agreed, signed an agreement for the production of 200 aircraft, although it is produced on the production line in China, but they still have to provide a lot of materials, and they can still make a profit.

For example, the first batch, that is, the way of assembling the parts, they produced the parts, handed them over to China, assembled them domestically, and then, step by step, increased the proportion of domestic parts, and finally reached complete independent production, but the Russians still kept a hand.

Even if it is an engine, no matter how they negotiate, they will definitely not authorize China to produce its own engines in China.

In the past, all kinds of fighters introduced to the Soviet Union were all in full sets, including the fuselage and engine, but only when the Su-27 was introduced, this convention was broken, and the engine was not introduced simultaneously.

In this way, if you want to produce in China, you always have to turn to the Russian side, without their engines, your own aircraft will not be able to go to the sky, and on the other hand, the domestic turbofan ten engines are continuing to be developed, so there are replacement products in China, and in this way, the engine was not introduced in the end.

On the one hand, Shenyang is closer to the Russian Far East, and the parts produced from Komsomolsk are easy to transport, on the other hand, it is the domestic military aircraft research and development institutions, Chengdu is already busy with the J-10 project, although Shenyang keeps saying that the J-8 is enough, the Air Force is not at ease, so the localization task of the Su-27 was handed over to Shenyang, and the localized Su-27 was named J-11.

In recent years, the domestic military aircraft have been developing rapidly, and the fleet of third-generation aircraft has been expanding.

He's under a lot of pressure.

After the agreement was signed, Shenyang began to improve their production equipment to prepare for the production of the Su-27, and now, they are in full swing preparations, and the first batch of localized J-11 is expected to come out at the end of the year.

"In the army, the call for the Su-27 is very high." Old Song said to Qin Feng.

"Well, I know." Qin Feng nodded.

Song Lao left, Qin Feng looked at Song Lao's back, and really didn't know what Song Lao's intention was when he said this.

After finishing the exercise, taking a shower, having breakfast, and entering the conference room, Qin Feng finally understood.

The pressure was so great that even Song Lao himself couldn't bear it.

Last time, it was Zhou Lao, the chief pilot of the test flight, who asked for a conservative counterweight for the first flight, and this time, Song Lao, who was full of white hair, took the initiative to put it forward.

"Our first flight was scheduled for March, as you know, it's not been a few days, for the sake of insurance, I think we can use counterweights, we can be more secure. After all, our first flight must not go any way. ”

Su-27 has begun to be produced in China, for the Air Force, this aircraft has been operating for several years, more and more convenient, now, the research and development of J-10, more and more attention is being paid to it, if something happens to the first flight, the J-10 project, may be gone.

After Song Lao finished speaking, he looked at Qin Feng with apologetic eyes, obviously, this is closely related to Qin Feng, and Qin Feng is resolutely against doing this, Song Lao took the initiative to bring it up because the pressure was too great.

"No, Old Song, I have the same opinion as before, and I firmly oppose it." Qin Feng said: "I oppose this, mainly for three reasons. ”

During this time, everyone expressed their opinions and argued a lot, Qin Feng also thought about it repeatedly, and now, he can clearly and methodically say all his thoughts.

"First of all, Mr. Song, you also said that our time is very tight, and there are only a few days left, can we complete the first flight of adjusting the center of gravity? Moreover, the test flight scheme of gradually reducing the counterweight in the future will require a long period to adjust to the actual state, which our development cycle does not allow for this! We have the pressure of J-11, and under this pressure, we have to race against time, rather than wasting time in this aspect! ”

"Second, it's expensive. Since the construction of this aircraft, all our experiments on the ground have been carried out in accordance with the normal state of the center of gravity, if the first flight is carried out in the state of the center of gravity forward, in this case, it is inconsistent with the state of doing experiments on the ground, and many ground experiment results have lost their meaning, and we have to make up for it again; Will it be in time for the first flight in March? Perhaps, J-11 has made its first flight, and we are still doing ground tests here, we have already postponed the first flight three times, and we can't postpone it any longer! ”

"Finally, and most importantly, it's risky. We all know that the risk of the first flight is very high, as the chief test pilot, I am not afraid of taking risks, now this is actually for me to take two risks, first to the front center of gravity of the aircraft for the first flight, after the end of the year I have to return to a state of unrest to make the first flight again, rather than taking two risks like this, it is better to let me take a risk! ”

Qin Feng looked at Song Lao with a firm gaze: "Old man, I have confidence in our telex system!" ”
