Set sail1992

Chapter 550
Two days later, Konstantin Antonov and Sergey Izotov came to Zhang Qihang's office together with their work report, or project development plan.

After exchanging pleasantries, Sergei Izotov said to Zhang Qihang: "Zhang, I have discussed with Antonov. My side is still focusing on heavy oil piston aero engines and taking students. The helicopter side, As for the position of chief designer of the helicopter, I think Comrade Antonov is more suitable."

"Is that so?"

Zhang Qihang nodded, then turned to look at Konstantin Antonov.

"Yes," Konstantin Antonov nodded, and continued: "I need 10 assistants here, and everyone needs a computer. In addition, if possible, it is best to allocate it to our project team. A dedicated medium-sized computer."

After finishing speaking, probably worried that his requirements were too high, Konstantin Antonov added: "If these conditions can be met, I promise to make a prototype within half a year."

The reason why Konstantin Antonov has such strong confidence comes from his strength. Although he was not the chief designer or even the deputy chief designer of any type of helicopter during his time at the Miri Design Bureau, he participated in The multiple helicopter projects of the Miri Design Bureau are indispensable members of the entire design team, and their abilities are naturally leveraged.

Konstantin Antonov's words made Zhang Qihang a little surprised: "Make a prototype in half a year? Are you sure?"

"Half a year is enough. Frank Robinson was able to make the Robinson R22 in his garage for two and a half years. We have such a mature team and such good working conditions. If we can't make a prototype within half a year, We don't even have the face to take your salary."

Konstantin Antonov said confidently, in fact, in Konstantin Antonov's view, if he didn't need to be familiar with the technical indicators and safety standards of the China Civil Aviation Administration for helicopters, he would have spent half a year No, because the working conditions of Huateng Industrial Group are too satisfying to be satisfied.

After Konstantin Antonov and Sergey Izotov and other experts from the former Soviet Union came to Huateng Industrial Group, in order to reassure everyone—of course, it can also be understood as showing the company to the old men. The hardware strength——Zhang Qihang took everyone to visit the technology research and development center of the group.

To be honest, before the visit, these old men were really worried about the hardware level of Huateng Industrial Group in terms of scientific research. After all, in the eyes of most Soviet experts, the level of technology and research and development of Huaxia was still very backward. Some people even worry that after arriving in China, they won't have to do paperwork again in the 60s, right?
But after visiting the design and R&D center of Huateng Industrial Group, all the former Soviet experts, including Konstantin Antonov and Sergey Izotov, simply dropped their jaws: but just In terms of the level of scientific research hardware, the strength of Huateng Industrial Group is even higher than that of its work unit in the former Soviet Union!
How high is it?

So high that in the scientific research center of Huateng Industrial Group, everyone has a 386 computer, and all the computers have realized local area networking!
In addition, in order to improve the computing power of the scientific research center, Huateng Industrial Group even equipped several medium-sized computers. Although there are no large-scale computers, these medium-sized computers were bought only last year. In other words, it doesn't even belong to the mainframe of 10 years ago!

Looking at these personal computers and mid-range computers, even former Soviet technologists like Konstantin Antonov and Sergey Izotov couldn’t help drooling: Good stuff, really It's a good thing.

Although the Miri Design Bureau and the Klimov Design Bureau have also realized the computerization of research and development, but to be honest, the computers of the Klimov Design Bureau and the Miri Design Bureau are still domestically produced in the Soviet Union in the early 80s. The level of technology was not bad at the time, but it has not been updated in these years, and the performance is naturally not comparable to these computers and medium-sized machines of Huateng Industrial Group.

If you didn't see it with your own eyes, who would dare to believe it?
"10 people, no one is equipped with a computer? Of course no problem," Zhang Qihang nodded happily and agreed: "The medium-sized computer is also no problem, what about the funding? How much is the funding required?"

"This one……"

Konstantin Antonov thought for a while, and said: "I'm not familiar with the purchasing power of China's RMB, so I can't give you an accurate answer for the time being, but if it is calculated in 1990 rubles, I think that in addition to In addition to the engine, a fund of 100 million to 200 million rubles is enough, after all, your requirements are too low."

It is not clear what the dialogue ratio between the ruble and RMB was in 1990, but it is certain that it will never exceed 1:2, that is to say, the top three 400 million research and development funds.

So Zhang Qihang readily agreed: "That's it, no problem, um... In this way, we will ask the finance department to allocate 100 million to you first, and then allocate it later if necessary. In addition, for the convenience of obtaining evidence for the next test flight, Let's make 3 prototypes directly, do you have any questions?"

"No problem, of course no problem."

Konstantin Antonov did not hesitate at all. For him, it made no difference whether to build one prototype at a time or three prototypes.

Zhang Qihang nodded, then turned to look at Sergei Izotov: "Mr. Izotov, you should be familiar with the modular concept, right?"

Modular concept?
Sergey Izotov laughed, nodded and said, "It's okay, I know more or less."

Zhang Qihang nodded, and he didn't believe that Sergei Izotov didn't understand the concept of modularization. You must know that the concept of modularization was first born in the military field. Repair the damaged equipment quickly. As the second chief designer of the Klimov Design Bureau, Sergei Izotov would be a big joke if he didn't understand the modular concept.

"It's like this," Zhang Qihang said, "If possible, I hope you will adopt a modular approach when designing and developing our aviation kerosene piston engine, such as the displacement of each cylinder, bore, and the number of valves. The parameters and other technical indicators are constant, and different power requirements can be realized by increasing the number of cylinders in the later stage, and during maintenance, the generalization of parts can also be realized as much as possible.”

This is the modular concept of a car engine. In the end, each cylinder has a displacement of 500CC. The inline four-cylinder is exactly 2.0, and then one cylinder is cut off to become a three-cylinder...

"Understood, no problem," Sergei Izotov nodded cheerfully: "If it is the early stage, how many engines are needed?"

"Two types," Zhang Qihang said: "One meets the needs of the two-seater helicopter we are developing. In addition, in the future planning, the group is also planning to develop an ultra-light four-seater piston-powered helicopter... …well, the Robinson Corporation of Millikin is also designing such a helicopter, called the R44, powered by a 245 hp Lycoming IO-540 flat-six engine."

Zhang Qihang even mentioned the reference object and the engine used by the reference object. What else does Sergey Izotov not understand?What Huateng Industrial Group wants is a four-cylinder gasoline engine that can meet the power requirements of a two-seater helicopter, and an engine with a power of around 245 horsepower that can meet the needs of a four-seater helicopter?
"These two engines were the main ones in the early stage, right? No problem," Sergey Izotov responded, "Then what about the cooling method and cylinder layout of the engine? Do you have any suggestions?"

Zhang Qihang pondered for a while. For now, the piston aero engines of Lycoming, ROTAX, and Continental almost all choose the air-cooled, horizontally opposed structure, but Zhang Qihang knows better. In the future, ordinary supercharging will no longer be able to meet the demand. Piston-type aero-engines will even use two-stage supercharging to increase the flight altitude. Regardless of the heat dissipation requirements of the engine, liquid cooling with higher efficiency will be the mainstream of piston aero-engines in the future. Therefore, Zongshen Hangfa and Haery Power, established in 2014, almost without exception chose liquid cooling. Since there are such good His reference object is in the front, so he naturally has no reason to continue to insist on air cooling.

It’s just that in terms of the basic structure of the engine, whether to choose a V-shaped structure or a horizontal confrontation, Zhang Qihang was a little undecided for a while. However, in view of the fact that the most successful piston-type aeroengines during World War II: the British "Merlin" series engines were V800 liquid-cooled, Zhang Qihang pondered for a while, and finally decided: "My personal suggestion is a V-type, full-aircraft engine. Liquid cooling, and there may be an increase in the second level in the future, Mr. Izotov, do you have any suggestions?"

"V-type, the whole machine is liquid-cooled, and there may even be a second-stage supercharger in the future?" Sergey Izotov pondered for a while, then nodded: "I have no problem, just follow your wishes."

For Sergei Izotov, no matter what structure and cooling method is used, he doesn't care much. In fact, in his eyes, compared with the turbine, the piston machine is really too simple.

Sergey Izotov gave himself full respect, and Zhang Qihang was also very happy. After thinking for a while, he continued: "I know that compared with gasoline engines, the technical difficulty of kerosene-powered piston engines lies in the fuel consumption. Atomization technology, the structure and shape of the living combustion chamber, I have no advice for you about the combustion chamber, but for the atomization of fuel, I suggest that you refer to the technology of inkjet printers. Very small handwriting can be printed very clearly."

Zhang Qihang can’t remember when he read a piece of information, probably when a certain domestic company was developing a piston aircraft engine fueled by aviation kerosene, how to atomize aviation kerosene became an obstacle. Many methods failed to solve this problem. Later, when printing documents, someone saw that the inkjet printer of the unit could print very small fonts clearly, and suddenly came to inspiration, thinking that the nozzle of the inkjet printer could be I learned from the technology, but I didn't expect that not only was it successful, but the effect was also very good. The atomization effect of kerosene was much more ideal than imagined.

Now that there is a ready-made reference object in front of him, Zhang Qihang naturally can't go any further.

Hearing Zhang Qihang's words, Sergei Izotov, who has been thinking about how to do a good job with this kerosene piston engine for the past few days, his eyes lit up, and he nodded immediately: "Inkjet printer? Okay, I I’ll take a closer look when I get back.”

........................

When Sergei Izotov and Konstantin Antonov had brought their teams and students into their work, Deputy Manager Tang of AVIC in Beijing frowned and went to the office of the head office The director asked: "Old Ren, if I remember correctly, the group of Russian experts invited by Shandong Province has already arrived, especially Mr. Sergei Izotov from the Klimov Design Bureau. It's been so long, I haven't heard the news?"

Aeroengines are our country's biggest shortcoming in the field of national defense and military industry. As the second-generation chief designer of the Klimov Design Bureau, he presided over the design of various turbofans, turbofans and turbofans such as RD-33 and TV3-117. Even though Sergei Izotov is almost 70 years old now, with limited energy and can no longer enter the front line of work, the knowledge in his mind is still an extremely precious wealth. His arrival can greatly It has greatly improved the scientific research level of AVIC in aero-engines, so Sergei Izotov, the second-generation chief designer of the Klimov Design Bureau, AVIC actually attaches great importance to it. Sergey Izotov's family's small villa has already been prepared, but it's time. Sergey Izotov should have been here for more than a week. Why hasn't anyone come to report to him? What about Izotov?
Deputy manager Tang was a little unhappy.

Director Ren was stunned for a moment, and then quickly said: "Manager, I have been paying attention to the movement from Lu Province, but we have not received a call from Lu Province."

"Didn't receive the call?" Deputy Manager Tang was also stunned. He frowned and thought for a moment, then nodded and said, "Okay, it's okay, you can go out."

Calculating the time, Sergei Izotov has definitely come to Huaxia. Under such circumstances, the comrades in Langya area and even Lu province have never contacted AVIC. Deputy Director Tang already has a judgment in his heart: it must be Something went wrong.
