"That's nature. Regardless of whether it is done by our country or not, we must be able to use it before we can support it, right? Regarding Yun Fei's words, Ma Fengshan thought so.

Yun Shi's fall made him very strict about research funds, and he could save everything he could. He didn't want to see his big plane project end again because of financial problems. Especially Yun Fei is a private boss, and he can take out a huge amount of money that even the country is unwilling to lose to engage in a handjob project that does not see any profits.

This is inherently commendable, and God knows if he did this project on impulse.

If you see that this research project is like a bottomless pit, you will definitely give up on investing in it because you spend too much money in some places.

"Yes, even if we support domestic production, we must be able to meet our use requirements, otherwise in the end we will not be able to run ourselves, and there will be no funds to provide to them. Since the old man asked us to be the first to eat crabs this time, it is very likely that those military aircraft factories are unwilling to use them or the state is unwilling to invest money. "Cheng knows the industry very well from time to time.

Yun Fei was stunned for a moment: "Two, I didn't mean that......"

"That's what we mean......," said the two old men, almost in unison, and when they had finished speaking, they were both stunned. After glancing at each other, a faint smile appeared on Yan Sù's face.

Only by maintaining a high degree of consistency in these things can we devote all our energy to technical research. Otherwise, in the end, they will drag each other every day, and don't expect any results in the end.

"Xiao Hou, I really didn't expect that you are the director of this 810 Research Institute......" When Yun Fei introduced the director of the 810 Research Institute, Ma Fengshan was suddenly surprised.

"Hehe, Ma Lao, we haven't seen each other for many years...... Hou Mingrui said to Ma Fengshan with a smile on his face, although he was surprised that Ma Fengshan was not dead. But many of their institutes are "dead people". So the surprised Cheng dù was not too high.

Yun Fei really didn't expect that these people actually knew each other.

Doesn't it mean that Hou Mingsong was already in this 810 research institute when it was established? This guy looks like he's just over fifty, right?

Seeing Yun Fei's puzzled face, Huang Qiaosong explained to him with a smile: "At the beginning, Hou Mingrui was only a junior in the turbofan eight project, although Lao Ma did not study aerodynamics. But it also taught him a lot. After all, the propulsion system is only one component of the entire aircraft. ”

Yun Fei really didn't expect that there would be such a relationship between the two sides.

After a pleasantries. Once again, everyone entered the research room at a depth of 100 meters through the Soviet expert building.

When I first came here, I was shocked that this research institute outside of history and China had such technology because I heard the introduction of Hou Mingsong and Huang Qiaosong. Yun Fei really hadn't properly observed this huge space deep underneath.

This is basically just responsible for some research design and calculations, of course, including the final process assembly, as for how these huge engines are shipped out after assembly, no one knows.

"Yanhuang type 1 is a geared turbine engine, a turbofan with a fan diameter of 80 inches, which is divided into three pressure zones, seven groups of impellers in each area, a total of 21 levels, each stage is operated independently, and the JT8D-200 of the noise Pratt & Whitney Company is smaller......" Hou Mingrui's introduction this time is obviously much more professional.

When Yun Fei came two days ago, he didn't introduce these parameters.

"The diameter of this fan is a bit big for a small regional airliner...... "Hearing Hou Mingrui's introduction, Ma Fengshan immediately frowned. Generally speaking, fans with a diameter of more than 80 inches are used on mainline airliners.

GM's GE90 engine was the engine they were going to use on the Yun 20 mainline airliner at the beginning.

The fan is only 90 inches in diameter.

One inch equals 25.4 millimeters, which means that the entire engine is more than two meters in diameter, which is a bit bulky for a small regional airliner.

"This is not too big, the regional airliners used in the European and American markets are almost the same size......," Hou Mingrui said with an embarrassed face, he felt that an expert like Ma Fengshan should not ask such a layman's question.

Cheng shook his head from time to time, and said with a smile: "It's not wrong that their old engine is this size, but the new engine PW6000 series developed by Pratt & Whitney and General Motors specifically for regional airliners has a fan diameter of sixty inches, and of course, they have only started ground tests now......

These things, if it weren't for Yun Fei's proposal to ask for the best engine when he was negotiating with the people from Pratt & Whitney, Blair said that the JT8D-200 was the best engine, and Yun Fei directly reported this model, Blair had no choice but to let his technicians introduce them to this kind of small thrust engine specially developed by them for regional airliners.

Otherwise, Ma Fengshan and Cheng would not know from time to time.

These things are not to say that they are kept secret from Chinese, they are kept secret from everyone, although there are three companies competing in the aero engine market, and Pratt & Whitney cannot even compete with GE and Rolls-Royce, and the newly developed strategic engine will naturally not be disclosed to anyone.

Whoever takes the lead will occupy the market.

This is something that everyone understands.

"Ma Lao, we have such a design here, but because there is no research funds and the materials are not up to standard, it has always been in the drawing stage......" Hearing the other party's words, Huang Qiaosong spoke directly.

Although he said this to Ma Fengshan, his eyes were fixed on Yun Fei.

As soon as Yun Fei saw this Huang Qiaosong, the old thing, he was crying for money, and he was immediately angry: "I said Lao Huang, don't look at me, I am also a landlord now, and there is no surplus grain, I want money, I want to die......"

Now that he can't even borrow money, Yun Fei naturally won't promise research funds when he is not sure whether the engine of the 810 Research Institute can meet their needs, you must know that Huang Qiaosong's face is definitely thick enough, as long as Yun Fei opens this opening, he will come to the door immediately, and he will not give up if he doesn't get the money.

It was under such circumstances that J-10 succeeded several years earlier than the original world.

And now the 132 factory is engaged in the annihilation of 20 without too much financial allocation from the state, and the funding gap is even greater, Huang Qiaosong has found Yun Fei many times for this matter, but Yun Fei has never let go. What's more, if the engine of the 810 research institute meets their use, they have to invest in building a factory or something, which is not a small amount of money.

"What about you?" When Huang Qiaosong heard Yun Fei say this, he immediately rolled his eyes.

Under the gags of the two, it turned out that the embarrassment caused by Cheng saying from time to time that the aircraft of the 810 Research Institute was too large and bulky was gone.

"What about the design performance of a 60-inch diameter engine?" Ma Fengshan ignored Yun Fei and Huang Qiaosong, but asked Hou Mingrui directly.

"The thrust is about 12,500 pounds to 14,500 pounds, if it is only used for regional airliners with a range of 600-1,200 kilometers, this is not much of a problem......" Hou Mingrui heard Ma Fengshan's words, his eyes immediately lit up, they have not yet carried out prototype production, used for testing, just stay in the drawing stage, whether there is a problem with using computer simulation of this design, all because of lack of money.

And Ma Fengshan has enough say in Yun Fei's large aircraft project, so as long as he uses this to impress Ma Fengshan, Yun Fei has to pay for it if he doesn't want to pay it.

"Moreover, it is preliminarily estimated that the cost of the production test samples from 300 hours to 10,000 hours of long test, and finally 1,000 hours of continuous long test, will not exceed 500 million, and the budget should be controlled tightly, which should be enough at about 420 million......

Cost performance is the way to survive a product, especially a product that has not been introduced to the market and has been tested by the market, or even just a theoretical design, if you want investors to take out the money in their pockets, they must tell him how much research money he needs to invest.

As for the market situation, it is naturally a matter for investors to consider for themselves.

"Ma Lao, if the engine of the eighty-inch diameter fan can be used, use it first. There is no problem in carrying out new engine research and development tests at the right time, we have to save the emergency ...... now" Yun Fei saw that Ma Fengshan heard the figures reported by Hou Mingrui, and was about to agree to this matter, so he immediately spoke out to stop Ma Fengshan.

420 million, that's a theory!

If there is a problem with the design or something, three or four hundred and twenty million may not work, not to mention that even after these engines are put on the market, they must continue to be studied.

It's not that Yun Fei doesn't believe that the 60-inch aircraft engine of the 810 Institute can't be made within 500 million, but he really doesn't have confidence in this. If the other party is quoting two billion or billion, his confidence may be a little more sufficient.

"Also, let's go through the test numbers of these engines first." Ma Fengshan immediately understood what Yun Fei meant, and he didn't even see the rabbit, so he let the falcon out, and waited until the falcon was tired of flying to find the rabbit, and the rabbit might not be able to catch it at that time.

As China's own technology researcher, Ma Fengshan has little confidence in his own projects, let alone in others.

"When do you have time? Let's go to the Great Gobi in the northwest to see the high-altitude platform engine test over there. As long as that test is completed, the next step is the flight test......" On this, Huang Qiaosong did not force Yun Fei. (To be continued......)
