In the small conference room of the office building of Shen Huoyi Factory, there were more than a dozen researchers from the two projects, including Yu Niandong and Yi Xiaoyi. Yu Niandong came to coordinate the technology sharing work, and Yi Xiaoyi was already the main member of the new generation of scientific research team of Shen Hoy Factory.

Li Zhan first finished reading the latest improvement plan of the J-16, handed it to Zhu Qingying beside him, raised his chin, looked at Yu Niandong, and then looked at Yi Xiaoyi, the person in charge of the technology of the Shen Hoy Factory, and asked, "So now that your two factories have reached an agreement, the avionics technology of the fourth-generation aircraft will be used in the No. 16 project?" ”

"It is a research and development consortium led by our two factories, and relevant research institutes have also signed agreements." Yu Niandong nodded and said.

Li Zhan nodded slightly, "I personally approve of it." During the test flight, my overall feeling is that the No. 16 aircraft has made great progress compared with the Su-30, especially in terms of avionics technology, but in the long run, the advanced degree of avionics technology of the No. 16 is still doubtful. My opinion is that it is better to extend the service time than to use the advanced technology that has matured as much as possible. ”

Yi Xiaoyi said, "It is precisely because of this consideration that the army cannot accept the situation that it is backward in service, and our manufacturers are not willing to deliver a fighter that will be backward in the near future to the army." Under the coordination of the superiors, the sister factories were willing to share the avionics technology of the fourth-generation aircraft, which solved our biggest problem. ”

After talking for more than ten minutes, Zhu Qingying finished reading the plan, and when she put down the plan, everyone consciously stopped talking and turned their eyes to her. She was not ignored because of her non-active military status.

Zhu Qingying was very serious, she said, "The No. 16 aircraft will be the equipment of the Navy and Air Force in the future, and the characteristics of the Navy and Air Force need to be taken into account, but I do not recommend balancing." ”

"What do you mean?" Yi Xiaoyi asked.

Zhu Qingying said, "I suggest two models, the air force type and the navy shore-based type, and the general rate of parts and components can be appropriately reduced and more targeted." Then on the two basic types of development of the use classification of models, such as the Air Force type, the development of electronic warfare aircraft, fighter-bombers. ”

"I see what you mean." Yi Xiaoyi nodded and said while quickly recording it.

Zhu Qingying looked at Li Zhan and said, "Let's talk about it from HNA." ”

Nodding slightly, Li Zhan said, "Shen Hoy Factory is very experienced in naval fighters, not to mention the rest, I mainly put forward two suggestions, the first is a long range, a larger fuel load, which is very important for the naval aviation troops in the future, and the second point is to make a command aircraft, which can carry air command, and can realize relay communication and target guidance after carrying the pod." ”

"Understood." Yi Xiaoyi recorded it again.

What Li Zhan and Zhu Qingying said was the experience gained at the cost of blood, and every word was extremely precious. Zhu Qingying has never worked in the naval aviation unit, and she has a deeper understanding of the air force.

After the general party made clear suggestions, everyone began to have a heated discussion on the details. The specific installation position and size of the rearview mirror should be seriously and fully discussed. Rich flight experience has made Li Zhan familiar with all the situations of the fighter, and the basic J-16 is the actual combat test flight completed in his hands.

There is no level of such technical seminars, and everyone does not discuss virtual topics, but all flesh and blood dry goods. Although Zhu Qingying has never driven a J-16, her flight hours have reached more than 4,000 hours, which is more than twice that of Li Zhan, and she is richer than Li Zhan in terms of flight experience, except for the experience of handling dangerous situations.

It took three days to finalize the latest improvement plan for the J-16, and then the R&D team still has a lot of work to do, and the engineering plan can only start manufacturing after forming an engineering plan, but these are not things that Li Zhan can interfere with.

Immediately after discussing the improvement plan of the J-15, it should be pointed out that although more than a dozen J-15s have been handed over to the troops, this fighter has not been finalized, and it is unique in the history of military aircraft development.

The J-15 is even more problematic.

At the discussion meeting, Li Zhan said, "In general, the biggest problem of the J-15 is the engine. The thrust of the engine used now is not enough, and there is a big gap compared with the international advanced level. Another is the durability of the engine in bad weather. ”

Yi Xiaoyi said, "Mr. Li, the new engine has been in the final stage of tackling key problems, and the power institute has made it clear that it will be able to be tested on the machine this year, and it will not be far from being installed at this step." ”

"The second problem is also very serious." Li Zhan's expression was very serious, and the scene of Zhang Xueyang blocking the landing and encountering a flight control failure appeared in front of him, and his fingers tapped on the table and said, "The flight control system of the J-15 must be replaced." The failure of the old flight control system has caused a number of serious accidents, which are far more fatal than the poor thrust of the engines. ”

These words made the technicians of Shen Huoyi Factory full of shame, and they really didn't have any confidence when they wanted to refute it. After Zhang Xueyang suffered a flight control failure, the Shen Huo Yi factory was severely approved by the superior competent unit, requiring that the hidden danger be solved as soon as possible.

However, there are certain laws in the study of science and technology, which cannot be changed by administrative orders. There is no other way, Shen Hoy Factory and related research institutes can only work hard, and use whatever resources they want, regardless of the cost.

If the problem of the flight control system is not solved for a day, the J-15 will not be finalized for a day, and the failure to be finalized means that it cannot be delivered to the troops, and the factory can only continue to invest funds, which is very stressful. The dozen J-15s delivered in front were produced with the advance money of the troops, but it was impossible for the troops to continue to allocate funds when the fighters were not finalized.

Yi Xiaoyi knew that when it came to the J-15 project, he would definitely be severely criticized by Li Zhan, although he was mentally prepared, but at this time, when he saw Li Zhan's cold gaze, he was still very flustered, and said hard, "Mr. Li, we have decided to solve the problem of the flight control system regardless of the cost, and with the help of brother factories, we will overturn and restart and build a set of J-15 flight control system with independent intellectual property rights." ”

At this time, Yu Niandong, who rarely spoke in the J-15 project, smiled and helped speak, "Mr. Li, Yi Gong is right, we have concentrated our forces together, and we also use the avionics technology of the fourth-generation aircraft to derive, or it will take a lot of time to come up with a reliable and advanced J-15 flight control system." ”

Li Zhan said in a deep voice, "I often tell my soldiers that taking off is like stepping on the ghost gate, and every pilot must be mentally prepared to sacrifice at any time when taking off the plane. We are not afraid of sacrifice, but we hope that the comrades of military research and development can make our sacrifice more valuable! ”

Very heavy topic, very heavy pressure.

No one wants to make sacrifices, but it is useless to think about it, the cause of Zhang Xueyang's accident is the failure of the flight control system, and the responsibility lies with the manufacturer, which they must accept in its entirety.

Li Zhan did not continue to put pressure on them, took out a thick flying experience and handed it over, and said, "My experience of using the J-15 is all here, there are data and feelings, suggestions and opinions, praise and criticism, and specific suggestions for improvement." ”

"Great!" Yi Xiaoyi can be regarded as relieved.

Obviously, Li Zhan will not just put pressure on them, and Yi Xiaoyi is very aware of the value of these materials written by Li Zhan. What kind of plane makes Li Zhan fly like that, no matter how hidden the hidden dangers and problems will be exposed, it is more powerful than the ace test pilot.

Li Zhan did the actual combat test flight of the J-16 and submitted a detailed test flight report at the beginning, so this time he did not specifically write about the flight experience of the J-16, and for the J-15, he has too much to write.

For the J-15 project, Li Zhan and Zhu Qingying stayed at the Shen Hoy factory for more than half a month.

In April, the four-month tour of the investigation finally ended, and the little life in Ying Wanjun's belly had been more than five months at this time.

Zhu Qingying and Li Zhan piloted the business jet to land at the Fertile Naval Flight Training Base, and after stabilizing the plane, Zhu Qingying breathed a sigh of relief after uncovering the seat belt, and said to Li Zhan, "I'll send you here." ”

Li Zhan, who was about to get up, was stunned for a moment, sat down again, looked at Zhu Qingying and said, "Senior sister, stay here for a few days, I'll take you around." ”

Zhu Qingying looked at Li Zhan and smiled softly, "Li Zhan, we may not meet again in the future." ”

The feeling in my heart has finally been verified. In fact, when he set off from Fuzhichang Station more than four months ago, Li Zhan felt that something was wrong with his senior sister. Although he was indeed ordered to visit various military units together, Li Zhan always felt that his senior sister was sentimental, talked more, and her temper improved, and the whole person changed.

It's finally here.

"I can't ask where you're going or ask you to stay, I'm really sad." Li Zhan said with a deep sigh.

Zhu Qingying said softly, "It was once difficult for the sea to be water. We've been through a lot of things that others can't, and you say the days ahead will be like. Wonderful, uninteresting, or The Walking Dead. Rong Ma will eventually unload his armor and return to the field in his life. You're still young, but I'm not young anymore. ”

Li Zhan was silent.

In the past so many years, Zhu Qingying would disappear, sometimes for several months, sometimes for a year or two, no matter how long it was, she would always appear. I'm afraid I'll never see you again this time.

"Alas, the feeling of parting is really unpleasant." Li Zhan shook his head and said.

Zhu Qingying stretched out her hand and gently stroked Li Zhan's face, saying, "It means that you are still young, and when you reach my age, you will have another feeling when you encounter the same thing again." Go ahead and live your life well. Although we won't see each other again, I want to know that your situation is easy, you know. ”

"Okay."

Li Zhan got up and left the cockpit, and he didn't look back.

The hatch slowly closed, and the business jet taxied to the take-off position, and soon began to slide, climbing lightly on wheels, and soon disappeared into the far side of the sky. Zhu Qingying wiped away her tears and flew westward.

Li Zhan stood there for a long time without moving, slowly raising his right arm and saluting in the direction of his senior sister's departure, completely sending away the last trace of the old army.

He knew it was time for him to go.

In the following month, the Flying Shark unit no longer arranged for Li Zhan to fly, and Li Zhan concentrated on compiling training materials. He rationally integrated all the experiences and methods and compiled training materials and training outlines for carrier-based fighter pilots. This was his last contribution to the Flying Sharks.

As early as more than a month ago, Dai Wenming and Li Zhan had a phone call, and the Air Division had reached an agreement with the Sea Division that in view of the fact that the training of the Flying Shark unit was on the right track, the Air Division needed Li Zhan to return to the Air Force to participate in the test flight of the fourth-generation aircraft. The test flight of the fourth-generation aircraft has entered the stage of tackling tough problems, and Li Zhan is very important to this work.

Although he was extremely reluctant, Hai Si still considered the matter from the perspective of the overall situation, promised to return Li Zhan to the Air Force, and at the same time reached an agreement with the Air Force that the naval forces could make a short secondment when Li Zhan was needed, of course, the premise was to first ensure the test flight mission of the fourth-generation aircraft.

My comrades-in-arms are here.

Zhang Xueyang, Han Hongjun, Cheng Da, Niu Yaoyang, Cao Fufei, and all the officers and men of the Flying Shark Unit, who had already been discharged from the hospital, even the pilots who were training on the aircraft carrier returned to the scene to participate in the event in order to see Li Zhan off. Mr. Zhang, who has retired, attended the farewell party in full costume, and the leaders of the old flying shark troops such as Lao Chen Tou, Mo Ren'an and so on attended.

Revolutionary soldiers are bricks, where they are needed, they are moved. Everyone understands the truth, parting happens every day, and many times it is even too late to say goodbye, which everyone can understand very well. But Li Zhan, who is regarded as a spiritual pillar, is leaving, and everyone's mood is very uncomfortable.

The farewell party was also a commendation party, and Haiji decided to give Li Zhanji a first-class merit in recognition of his outstanding contributions during his service in the navy. Li Zhan received his tenth first-class merit.

He made a brief speech, looked at the hundreds of HNA athletes, and said in a calm voice: "Comrades, in the past year or so, we have created a new era of the People's Navy together, and we have witnessed history together. I am very touched and honored to stand with you. We are about to usher in a great era, and you who stand at the forefront of the tide will eventually be remembered by history. All our efforts are for the sake of those who come after us to better push up the combat effectiveness of the troops. Everything we do will be significant. It is the mission of our generation to resist the enemy thousands of miles away. I will continue to work hard with you in my new position! I hope that you will continue to climb the heights and continue to contribute to the building of a strong people's navy! Finally, I wish you all a safe take-off and a safe landing! ”

When it was time to say goodbye one by one, one counted as one, no matter how old or what level, when saying goodbye, holding Li Zhan in pain, the good Chinese sons and daughters who stood up to the sky cried like children, and that scene made Mr. Zhang and other leaders cry all over the place.

At the end of the farewell, Li Zhan saluted his comrades and told everyone loudly: "I am proud to be able to fight side by side with you!" Brethren, there will be a time later! ”
