Now that the purpose of Wang Dazhi's trip has been understood, and the performance of the "tay" MK1110 engine of COMAC Group looks really good, then the next thing is simple, the soldiers are all cheerful people, in the afternoon meeting, after a few simple greetings, He Xun went directly to the topic, and asked Wang Dazhi: "General Manager Wang, let me ask, the 'tay' MK1110 engine that you are going to reequip the Il-76 transport aircraft this time is with your company' What does the engine in the Tay' series have to do with it?"

This issue is also the issue that several commanders of the aviation division are most concerned about.

Wang Dazhi bowed slightly: "Division Commander He, Political Commissar Hong, Deputy Political Commissar Qin, it's like this, the 'tay' MK1110 turbofan engine is a common military and civilian model in the 'tay' series of aero engines, and it is also the model with the largest thrust so far in the 'tay' series of engines, with a maximum thrust of 110KN,"

After a pause, Wang Dazhi added: "According to our development plan, it is to push the thrust of the 'tay' series engine to about 150KN. ”

He Xun and Hong Jianzhong were taken aback when they heard this.

In their impression, an engine corresponds to a thrust range, for example, the D-30KP-2 engine on the Il-76 in their division is only a member of the D-30 engine series, and the D-30 series engine has a model adapted to the Tu-154M, a model for the civilian version of the Il-76 (the cannon installed in the tail is canceled), and a model adapted to the military version of the Il-76 (tail organic turret), according to the different models of adaptation, the engine manufacturer can make some fine-tuning of the power, but the power output range of this engine of the COMAC Group is too wide, can it cover from more than 60 thousand Ox to 110 Thousand Niu?

And listening to the meaning of Wang Dazhi's words, it seems that their commercial aviation group is ready to cover up to 150 kN?

It's scary!

He Xun hurriedly asked: "Mr. Wang, can the thrust coverage of an engine be so large?"

"It's really possible," Wang Dazhi nodded with a smile: "Take the RB211 engine as an example, the RB211-535C equipped on the Boeing 757-200 has a maximum thrust of only 166 kN, and the RB211-524H-T equipped on the Boeing 747-400 has a maximum thrust of 270 kN, do you think this coverage is scary?"

He Xun, Hong Jianzhong, and Qin Ming couldn't help but smack their tongues when they heard this: There is a thrust range of hundreds of thousands of cattle? This is really terrifying.

Speaking of this, Wang Dazhi continued: "Of course, in order to achieve such a wide thrust coverage, in addition to relying on new materials and new technologies, we must also take into account the needs of future engine upgrades from the beginning, and reserve enough upgrade space for the engine at the beginning of the design. The first Royce aero engine designed with a modular concept, which means that the engine has a good foundation, so it can achieve thrust coverage of up to 150 kN.

Of course, 150 kN thrust is what we are working towards, but now, our civilian version of the 'Tay' series engine can already achieve 128 kN thrust. ”

He Xun, Hong Jianzhong and Qin Ming glanced at each other, and their eyes couldn't hide their surprise: Is this COMAC Group so powerful?

It's no wonder that they think so, but back to what we said earlier, although the middle and senior officers of these air force units have more or less heard of COMAC, their daily work is too busy to have time to learn as much as military fans...... Isn't it good to have this kung fu of COMAC and ponder how to improve its combat effectiveness?

Hong Jianzhong pondered for a while and said: "Mr. Wang, your COMAC Group is the largest civil aircraft manufacturing group in our country, I believe it is impossible for you to talk nonsense, but this ...... Wouldn't there be compatibility issues with replacing the engines of the Il-76 transport aircraft with yours?"

As soon as Hong Jianzhong said this, He Xun and Qin Ming stared at Wang Dazhi together, and they actually had this question in their hearts: Aircraft, especially large military aircraft, are highly complex and sophisticated equipment, not to mention that your "tay" MK1110 engine is a European and American product, and the D-30KP-2 on the Il-76 transport aircraft is a Soviet-based product.

"In the early stage, there will definitely be some compatibility problems," to the surprise of the three of them, Wang Dazhi actually admitted it, he nodded and said: "But in fact, the problem is not as serious as you think, for example, the Tu-204 passenger aircraft developed by the former Soviet Union is equipped with two models, PS-90A and Rolls-Royce RB211 engines, so there may be some problems in compatibility, but it should not be difficult to solve......"

Speaking of this, Wang Dazhi smiled slightly and said: "Moreover, the three leaders, if our modification can be completed this time, I believe you understand the great significance of this, then compared to this huge meaning, what is the difficulty encountered in the modification process?"

Seem...... That's the same thing......

The three of them glanced at each other, and had to admit that what Wang Dazhi said made sense: if this modification can be successful, the significance is too great, at least in the engine of the Il-76, we don't have to be controlled by others.

Thinking of this, He Xun finally spoke: "Mr. Wang, what you said makes sense, but we still need to discuss it...... Otherwise, let's talk about this first?"

"Good. ”

Wang Dazhi smiled and nodded.

He understood that Hexun was moved, but this matter had to be decided collectively.

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

Sure enough, after Wang Dazhi got up to leave, Hexun immediately expressed his attitude: "Lao Hong, Lao Qin, I think you can consider it." ”

In fact, he was already moved, but he was still a little worried, but with Wang Dazhi's explanation, the worries and doubts in Hexun's heart had reached the level of "I think I can go and see".

"If the situation is really as Wang Dazhitong said, I also think it is worth considering," Hong Jianzhong's thoughts were similar to Hexun's, and he immediately said: "But I think we should transfer a few technical leaders from the division to the COMAC Group for inspection and inspection, and if the engine of the COMAC Group is really fine, we will jointly write a report to the leaders with the COMAC Group." ”

In these years, who is more stupid than whom, even if it is a soldier, although the personality is straightforward, but can do this position, it can not be a tendon, just for the "engine to achieve independent supply, and excellent performance, in fuel consumption, easy maintenance, life and other key indicators far beyond the original engine, while the price is cheaper", as long as the thing is done, it is a great achievement.

Not to mention that such a thing is sent to the door on the initiative, even if it is not delivered to the door, you have to find a way to get in the car.

Qin Ming also followed suit: "That's what I mean. ”
