Some of the metal materials involved in Hongling engine are not yet mastered in China, and these materials can be used in aero engines in addition to being widely used in some other civilian fields. Qin Hai's idea is to have experts from the School of Materials and engineers from Plant 43A work together to develop these materials, making full use of Plant 43A's rich experience in aerospace materials to shorten the R&D cycle.

As for the sales after the development of materials, Qin Hai has full certainty, no one knows better than him which departments need what kind of materials, as long as he gives some guidance to the sales staff, there is no need to worry about sales at all.

Qin Hai calculated in his heart that the sales profits of these metal materials were more than enough to compensate for the development investment in the early stage, and such a business was very worth doing.

Regarding the plan proposed by Qin Hai, Lu Hexing did not dare to agree casually. He was silent for a while and said, "I am personally inclined to agree in principle with this matter. But what to do, whether it involves the principle of confidentiality, still needs to be discussed by the party group of the academy to determine, and finally needs to be submitted to the Commission of Science and Technology for approval, so I can't answer you right now. ”

"I totally understand." Qin Hai nodded and accepted Lu Hexing's explanation.

"Okay, let's put this matter here first, does Mr. Qin have any other questions?" Lu Hexing asked.

Qin Haidao: "What I said earlier is just some relatively small cooperation, and I have a bigger idea, I don't know if I should talk about it or not." ”

"Bigger ideas?" The eyes of the room widened. If the sharing of precision machining equipment in the 43A factory is barely a trivial matter, the cooperation between the two sides in the development of engine materials is definitely not a small cooperation.

Among the more than 100 kinds of metal materials required by the Hongling engine, more than 50 kinds need to be developed, and Huang Dongfeng estimated that the development cost may be as high as tens of millions of yuan, which is still a situation in which researchers do not take a detour. If you are not careful. If the idea goes wrong, millions of dollars of R&D funds may be wasted, which is not lacking in precedents in the process of material research.

Such a matter involving tens of millions of yuan, Qin Hai actually said that it was only a relatively small cooperation, so what would the bigger idea he want to say?

All of them stared at Qin Hai. Wait for him to finish. Qin Hai deliberately sank for a moment, and then said with a smile: "Don't look at me like this, it makes me a little nervous." In fact, what I want to say is that since the military order of Hongling Engine is insufficient and cannot support this project, President Lu and Director Yan, have you considered converting it into civilian products for sale? ”

"Poof!"

Hearing Qin Hai's words, in case Feng didn't react much, Lu Hexing and the other three almost spurted out a mouthful of old blood. Qin Hai flickered just now. Let everyone have a sense of appreciation and awe for him, thinking that he is an expert and his words are decent. When he said that he would transform the Hongling engine into a civilian product, the tall image that everyone had built up with great difficulty collapsed all of a sudden.

Please, the engine is not a piece of clothing, you can wear it to whoever you want. The Red Ridge is a military engine through and through, and if it is to be changed to civilian use, how much effort will be put into the middle. Do you know? Besides, China's civil aircraft industry is almost blank. If you change a civilian Hongling engine, who are you going to use it for?

Thinking like this in my heart, it is inconvenient for a few people to say it directly. Lu Hexing looked at Yan Quangen and motioned for him to explain the problem to Qin Hai. Yan Quangen set his sights on Huang Dongfeng again, wanting this nerd to say such offending words. Huang Dongfeng also wanted to push this messenger away, but a room full of people counted him as the lowest. If he is not allowed to do this kind of thing, who can do it?

"Ahem, Mr. Qin, you build yì, uh...... Very novel. However, this has to be turned into a civilian ......" Huang Dongfeng pondered how to explain it to Qin Hai.

Qin Hai smiled, waved his hand, interrupted Huang Dongfeng's words, and said, "Chief Engineer Huang doesn't need to say it, I know what you mean." I didn't say that I want to do civilian aero engines, I mean, can you make a civilian industrial aeronautical aircraft? ”

Aircraft modification? Huang Dongfeng's open mouth couldn't close all of a sudden, and he made trouble for a long time, Qin Hai had this idea.

The so-called aeroderic engine is a aeronautical gas turbine, which is a marine or industrial gas turbine transformed from an aero engine as the parent engine. Marine gas turbines are used as marine power, while industrial gas turbines are mainly used for power generation, and are also used for refrigeration and other fields.

In fact, as early as the beginning of the introduction of Spey engine, the Ministry of Shipbuilding Industry, the Ministry of Aviation Industry and the Chinese Academy of Sciences and other departments have begun to use it to develop marine gas turbines, and have achieved certain results. Since the development of marine gas turbines was not undertaken by Plant 43A, Huang Dongfeng did not know the specific details.

Two years ago, when he was attending a meeting in the system, he had heard that the ship power research department in Bingcheng had built a prototype of a "Speygai" marine gas turbine, and passed the test run. Unfortunately, like the fate of the Red Ridge Engine, this marine gas turbine could not find a ship to match itself, so it was also shelved.

"Based on the technical specifications of the Hongling engine, I think this engine can be converted into an industrial gas turbine with a power of 8 to 12 megawatts, suitable for small and medium-sized oil-fired power plants, especially as a power generation, heat and power and combined heat and power unit in oil fields. There are so many oil fields in our country, and in the next few years, there may be a severe power shortage in various places, and this kind of medium-sized industrial gas turbine will definitely have a huge market. Qin Hai introduced to everyone unhurriedly.

"Xiao Huang, do you think what Mr. Qin said makes sense?" Lu Hexing was moved by Qin Hai's thinking, as a leader in charge, of course he had heard of the concept of aircraft modification, but he had not touched the idea of civilian use. Now hearing Qin Hai say this, he suddenly felt that it seemed to be a good way out to engage in civil aviation reform, so he couldn't help but ask Huang Dongfeng to help make an assessment.

Huang Dongfeng frowned, gently tapped the coffee table next to him with his fingers, and said slowly: "Engage in industrial aviation reform...... It is indeed a way out. The original British factory also has a gas turbine modified by Spee, but the mother engine model they use is RB168-66, our model is MK202, the intrinsic flow is about 18% smaller than RB168, and the power will be significantly smaller than the former in the case of the same initial gas temperature. In addition, the MK202 has a five-stage fan, which is difficult for the top-cutting scheme......"

Lu Hexing anxiously interrupted his deduction: "What you said is too professional, you can sue me, can you change it, as for how to change it, this is a question that you will study after you go back." ”

"It can definitely be changed." Huang Dongfeng nodded categorically, "Bingcheng's side has succeeded in changing the navigation to the marine machine, and the difficulty of the industrial machine is less than that of the marine machine, so it must be able to be changed." ”

"That's good." Lu Hexing said, he turned his head to Qin Hai and asked, "Mr. Qin, do you think there is really a market for industrial aviation modification?" ”

"There's definitely a market." Qin Hai replied without thinking, "Gas turbine power generation is the future development trend, at present, we are still very backward in the design and manufacture of gas turbines in China, if we can seize this technological peak, we will definitely be able to make a profit." If the income is less than 1 billion a year, I can make up for it for you out of my own pocket. ”

Medium-sized gas turbines have lower technical requirements than aero engines, but are still high-tech products. As soon as something is stained with the word "high technology", it can basically be used as a synonym for a cash cow. At that time, the price of a 10-megawatt industrial gas turbine reached more than 10 million yuan, and the cost could not be used even one-third, which was definitely a profiteering product. The point is that there is almost no domestic gas turbine in this field, most gas turbines have to rely on imports, if the 43A plant can develop industrial gas turbines, countless units lacking foreign exchange will line up to send money.

As Qin Hai said, the two collaborations he mentioned earlier are all petty fights, and only the gas turbine project is the real big deal. If it can be done, the annual operating income of billions is not a problem at all.

"Mr. Qin's vision and courage are really breathtaking." Lu Hexing was sincerely convinced, "Hearing what Mr. Qin said, we know that we have been asking for rice with a golden rice bowl all along. Xiao Yan, after you and Xiao Huang go back, immediately make a feasibility report and submit it to the party group of the hospital. If this can really be done, we must persuade the Commission of Science and Technology to agree to our development of industrial aviation modification aircraft. ”

"Then I'll wait for good news." Qin Hai said with a smile.

"No problem, once the Science and Technology Commission gives us an answer, I will immediately send someone to inform Mr. Qin, and we will do it together." Lu He said righteously.

In fact, Lu Hexing can't do it if he wants to be righteous, although the technical forces to engage in industrial aviation reform are all in the 43A factory, but if they leave Qin Hai's support, they have no funds and no market experience, and this promising thing may have to be messed up. After communicating with Qin Hai, Lu Hexing also figured out that what he lacked here was not technology, but a market-oriented business philosophy, which was precisely Qin Hai's strength.

After saying this, Qin Hai didn't have anything else to say. Lu He's mood was so high that he insisted on pulling Qin Hai to drink, and claimed that he would not return if he was not drunk. Helplessly, Qin Hai could only call the sunspot and put down Lu Hexing and his party one by one.

This trip to the 70X Institute brought unexpected joy to Qin Hai because of the appearance of Lu Hexing and others. He made an appointment with Lu Hexing to meet in the future, and then together with Kuroko, he bid farewell to the 70X Institute and boarded a flight to the capital. (To be continued......)
