Wang Dazhi frowned and thought for a while, and asked Fang Zhiqiang: "Old Fang, where is the progress of 'Tay'-3??

"Tay"-3, that is, the third generation of engines developed on the basis of the "Tay" series of engines.

If the "tay" series engine with a thrust of 60KN installed on the Fokker F100 is the first generation of "tay" series engines, then the "tay" series of engines with thrust from more than 70 kN to 110 kN introduced by COMAC and jointly developed with Rolls-Royce Group is the second generation, and the so-called third-generation "tay" series engine is based on the second-generation "tay" engine, and the combustion chamber is re-optimized. A new generation of engines with a large bypass ratio design and digital zone safety control technology.

Because the foundation is still the "tay" series of engines, compared with the two competitors of V2500 and CFM56, "tay"-3 still has some gaps with the mainstream products in terms of fuel economy and easy maintenance, which is unavoidable, but as long as the "tay" can be successfully made, at least the gap between COMAC and competing products in terms of engines is not so big, and it also has the basis for developing 200-seat short-range narrow-range trunk aircraft.

"The problem now is that we thought we had eaten the 'tay' well, but in fact we found that we hadn't eaten it well," Fang Zhiqiang said with a wry smile: "For example, we have assembled a technical verification machine before, and all the technical indicators are normal during the ground test, and I have reported this to you." ”

"That's the case," Wang Dazhi nodded: "I remember when you were going to conduct a high-altitude platform test...... next time" Speaking of this, Wang Dazhi's expression changed: This means that this engine was not going well when it was conducting a high-altitude platform test?

Seeing Wang Dazhi's suddenly changing face, Fang Zhiqiang knew that Mr. Wang had realized that something was wrong, and hurriedly explained: "When the high-altitude platform test was carried out, the engine did not have any faults, but the technical indicators were a little worse, and we are still analyzing what the specific problem is." ”

Wang Dazhi was immediately depressed: What is this called?

When the test was carried out on the ground platform, all the technical indicators were normal, but when it came to the high-altitude platform, there was a gap between the technical indicators and the indicators given at the time of design, which must be a problem.

But Wang Dazhi knows that unlike the "TAY"-2 stage, it was jointly developed by COMAC and Rolls-Royce Group, and there was a problem, as the original design unit, Rolls-Royce quickly got it, and the current "TAY"-3 is completely COMAC's own way, and this problem is more troublesome.

The problem is that Wang Dazhi is not from a technical background, and he can't do anything about this situation, so he frowned and asked Fang Zhiqiang: "Old Fang, how long do you think it will take to solve the problem?"

"This ......"

Fang Zhiqiang hesitated, not daring to give a clear figure: if he said that he couldn't do it, he would be responsible.

But Fang Zhiqiang's hesitation fell in Wang Dazhi's eyes, but it became a manifestation of not taking responsibility: at the critical moment when the company needs you, you can't stand up?

Fortunately, everyone has worked together for so many years, Fang Zhiqiang has been conscientious all these years, and Lao Fang will retire in more than a year, and at this time, Fang Zhiqiang will be brought down, and everyone's faces are not good-looking, so he took a deep breath and said: "Since you didn't find the problem, didn't you think about asking Mr. Vadim to help you take a look?"

Fang Zhiqiang's face turned red with a "......", and he squeaked: "Uh...... This ......"

"Okay, you don't need to say it," as soon as he saw Fang Zhiqiang's appearance, Wang Dazhi knew that it was a small departmentalism again, after encountering a problem, Fang Zhiqiang didn't think of asking Vadim Rabinovich, the deputy chief designer of the former Soviet Union's Ivchenko Design Bureau, for help, but arched forward by himself, and the reason for his doing so was very simple: I ask you for help, and if you will have achievements in the future, whose credit is this? He interrupted Fang Zhiqiang's words, and he didn't care so much, and directly criticized: " Comrade Fang Zhiqiang, you are also an old comrade, how should you work, do you still need me to tell you?"

Wang Dazhi's words were almost merciless criticism, and Fang Zhiqiang's face instantly turned red like a red cloth!

But his family knows his own family affairs, and as he gets older and closer to retirement, he knows best what his attitude at work is, Fang Zhiqiang wants to use his old qualifications to make trouble, but Wang Dazhi's stern expression made him suddenly feel a thrill - he understood the warning in Wang Dazhi's eyes!

"Yes, Mr. Wang, there is a problem with my work, I will review it with the group," Fang Zhiqiang, who suddenly realized how annoyed Wang Dazhi was by his previous actions, hurriedly made a self-examination to Wang Dazhi: "I will ask Mr. Vadim to come to us and help us do a consultation." ”

Wang Dazhi's expression softened at this time: Everyone has been an old colleague for so many years, and if possible, he also hopes that everyone will do well. Hearing Fang Zhiqiang say this, he nodded: "Old Fang, you have to remember one thing, when it comes to technical strength, there is still a big gap between our commercial aviation and Boeing and Airbus competitors, and the reason why we have been able to occupy a place in the domestic civil aviation market over the years depends on the support of the country and these domestic civil aviation companies.

I hope that comrades will not regard the support of the state as glory, let alone the idea that "anyway, with the support of the state, the country will never allow COMAC to collapse, so it doesn't matter if we are a little lazy", because with the support of the state and fraternal units, we should be more ashamed and courageous, and be right for the support of the country. ”

Speaking of this, Wang Dazhi paused slightly and said: "I will then report today's situation to Chairman Chen, and I hope that Chairman Chen can give a guiding suggestion on the current situation of the group...... Comrades, I found out that after Chairman Chen didn't care much about the affairs of the group, everyone's work attitude began to gradually go wrong. ”

Want to report to Chairman Chen?

And do you want to let Chairman Chen give guiding suggestions?

As soon as Wang Dazhi's words came out, many people's faces suddenly changed, and some people were expressionless, but they didn't know what they were writing in their notebooks.
