Chapter 1201

"This This Isn't this the index of wd-72suv high-power military turbofan engine? " As like as two peas in the head of the Old Navy chief,

, a captain of the air force factory, suddenly showed a look of surprise. It was impossible to tell that the index of WD 62MVP high-power turbofan engine in the master's division was the same as that of the WD 72SUV high-power military turbofan engine, which was considered as a fat meat competition.

What does that mean?

In a word, Tengfei group completely put aside their group of people and did not talk about their own martial arts!

The problem is that they can't say what they are pointing at. Did they spend one cent of your money? Or whatever assistance you need?

There's nothing. It's all products made out of Tengfei group's own pocket. What do you have to say?

What's more, is the wd-72suv high-power military turbofan engine? It's not good at all! The obvious model is wd-62mvp. Even a primary school student knows that there is a difference of 10 numbers between 62 and 72. Can the two be the same?

Even if the wd-62mvp is also a high-power military turbofan engine, it is essentially different from the wd-72suv high-power military turbofan engine. Even if the performance index is exactly the same, the essential difference is inconvenient.

Just like monks and donkeys, they both talk about monks, but there is a difference between a commendatory word and a derogatory word in essence!

It is clear that the inside of the door, the surprised person in charge of the air power plant will be such a euphemistic query, otherwise it will directly scold the Tengfei group for not paying attention to the model.

The problem is that they didn't make wd-72suv, but wd-62mvp!

As for getting the so-called explanation, the person in charge of the aviation development plant had no hope at all. The attitude of the old chief engineer was Sima Zhao's mind. Everyone knew that he was responsible for Tengfei group and Zhuang Jianye was his own son.

You asked the old chief engineer to explain, and with his old man's temper, you said, "can your factory also make a spare aero engine for No. 10 project?" That would be embarrassing.

In fact, this person in charge reminds others, including the deputy director general, that Tengfei group is playing tricks on its models. When we wait for the scene later, when we see Zhuang Jianye and other persons in charge of Tengfei group, don't give advice. We have to unite anyway. Whether it's MVP or SUV, we have to let them join in.

How many stupid people can be responsible for the positions of the responsible persons of various aircraft development plants? Naturally, they understand the person in charge of the aircraft development plant who is surprised. As a result, before they reach an agreement with each other, the old chief engineer has a rare and pleasant explanation: "this comrade said that the index of wd-72suv is the same, indeed, the index data are similar, but according to the data If we say that the wd-62mvp is a variant of the wd-72suv, it is somewhat one-sided. The data of the Russian al-31 and the American f110-ge-129 are similar. Can we say that the al-31 is F110?

The same is true for wd-62mvp and wd-72suv. What is wd-72suv? It's a real high-end thrust military engine. In the early stage, the thrust to weight ratio of the mass-produced engine is set at 8. In the middle stage, the mature engine should reach 10. In the later stage, the development engine should be raised to 15, which will be the main power source of the next generation of combat aircraft.

Therefore, wd-72suv is not a single aero-engine, but a long-term development system. Just because of this, starting from the core aircraft, the standard of the whole project is very high. The third generation of core aircraft with power up to 25MW is needed. Based on this, the advanced aero-engine that can cover the next generation of combat aircraft can be derived. "

After a pause, he immediately pointed to the tnb-19s aeroengine test plane that had landed on the runway of the airport and continued: "the wd-62mvp obviously can't reach such a high standard. In terms of core aircraft, the wd-62mvp is half a grade worse than the wd-72suv. The wd-72suv is expected to use the third generation core aircraft, the wd-62mvp, with a conversion flow rate of 30kgs and a cycle power of 25MW Only the hx-25-17 core machine upgraded from the second generation core machine is used. The converted flow rate is 25kgs, and the circulating power is only 17MW. At most, it is a second generation and a half transition model.

The high-power engine made from such a core aircraft can barely be used in the production type of project 10, and the next generation of combat aircraft can't be expected at all. Otherwise, I can't use this engine as the spare engine of project 10. I really think the limitations of this engine are too great!

It can be seen from the specific index of wd-62mvp that the diameter is 1280 mm, the length is 4982 mm, the engine intake flow is 118 kgs, the bypass ratio is 0.78, the fuel consumption of afterburner thrust is 1.8 kgdan · h, the fuel consumption of cruise without afterburner is 0.6 kgdan · h, and the temperature in front of turbine is 1728 K, that is 1454 ℃At this moment, the general manager embraces his chest with both hands, and his thick white hair is flying in the summer breeze. With his patient and kind face, he has a great family style. His wd-62mvp and wd-72suv are more like the transcendence of the hero of Qingmei boiling wine. With the data of countless families, he really shows the great family style incisively and vividly.

However, in the ears of the deputy director general and a group of directors of the aviation development plant, they looked at the old chief engineer one by one, just like looking at monsters.

How dare you say such data is too limited?

Old chief engineer, did you come back from the future or just returned from Europe and America?

What is the level of domestic high-power military engine? Don't you have a B number in mind?

The indicators of wd-62mvp are not so simple as good. They are good enough to explode. Even to some extent, wd-62mvp has surpassed the Russian made al-31.

Not to mention anything else, just talking about the temperature before the turbine, the al-31 engine is only 1666k, which is equivalent to 1392 degrees Celsius, while the wd-62mvp is 1454 degrees Celsius, which is 62 degrees higher than the al-31 engine. This proves that the potential of wd-62mvp has not been fully realized, and there is still a lot of room for thrust improvement in the future.

After all, the actual fuel consumption of al-31 is 2.3 kgdan · h under the condition of thrust and 0.8 kgdan · h under the condition of cruise without thrust.

It seems that the difference between the values is not big, but if the large base number of tons of fuel in the fighter is weighted up, the difference will be considerable.

This gap gives wd-62mvp more endurance and longer range, which greatly improves the consumption of short-range air combat and long-distance attack combat.

Based on this, many responsible persons of aeroengine manufacturing plants are no longer there. Al-31 is compared with wd-62mvp, and even compared with American F110 aero engine, because wd-62mvp is almost equal to American F110 series engine, and even surpasses some indexes.

You should know that F110 series aeroengine is the core power of F-15, F-16, F-14, B-2 and a series of main fighters, carrier based aircraft and bombers of the U.S. Army, which can be called the classic aeroengine in the world.

Nowadays, wd-62mvp, no less than F110, is placed in front of your old chief engineer. As a result, your old man says that there are limitations. If the old chief engineer doesn't have high moral standards, these people can pull each other's necks and yell: you TM can't see it, give it to me, I want it, I want it!
