Chapter 1116

This is also the reason why people in charge of "Youshang" strongly do not believe that the wd-63zb high-power turboshaft engine of Tengfei group has such excellent performance.

In addition to superstitious belief in American technology, there are also huge benefits hidden behind it. You can live a comfortable life without suffering. Who won't work hard to maintain it?

I wish I were exhausted.

But now, Tengfei group is no longer lifting the table, but openly digging the ancestral graves of "friend merchants", completely killing their children and grandchildren. What's wrong? It's not your fault to fight with Tengfei group.

The question is, do they dare to compete with Tengfei group and the head of the headquarters?

Perhaps before the emergence of wd-63zb high-power turboshaft engine of Tengfei group, these "friends" could still use the so-called "model" of turboshaft to play a tightrope with the head of the headquarters, making the head of the headquarters powerless, and finally had to compromise with them.

But now, the wd-63zb high-power turboshaft engine is blankly there, and they dare not even borrow a hundred courage.

Who dares to push like before? Yes, then don't try to get the list from the headquarters.

What? Your model has good performance? Advanced technology?

How about Tengfei group?

This sentence alone can make "friend merchants" dare not fart.

Therefore, the "friends" who were called together, even if they had not discussed it in advance, still unanimously agreed with the outside world. It was incredible and unbelievable for all kinds of wd-63zb high-power turboshaft engine.

With their superb acting skills, they want to prove one thing to the head of the headquarters, that is, wd-63zb high-power turboshaft engine is not as powerful as claimed.

Even if the power of 3000 kW is high, the power to weight ratio is 9.5.

Who does Tengfei group think it is? American's own son?

The head of the headquarters has long been dissatisfied with these turboshaft manufacturers. Otherwise, they would not support Tengfei group to develop turboshaft engines.

Since it's a catfish designated by the head of the headquarters of the older generation, it should have the appearance of breaking pots and pans and stirring the Lingxiao hall like monkey sun.

Fortunately, in this respect, Tengfei group did not disappoint the senior head of headquarters, nor did it disappoint the current head of headquarters.

In the face of so many complaints and doubts from the responsible persons of turboshaft manufacturers, the head of the headquarters is not used to them. They are directly brought to the national gas power laboratory in the suburbs of Beijing, which is not long built in Hong Kong, because where is the wd-63zb high-power turboshaft engine of Tengfei group conducting a series of data analysis tests.

As a result, it's not too bad. At first glance, a lot of "friends" are completely stupid. Wd-63zb high-power turboshaft engine not only has the power to weight ratio of 9.5, as the head of the headquarters said, but also has better performance than the data released by Tengfei group.

Take the maximum emergency power as an example. What Tengfei group gives is 3267 kW. In fact, the data measured by the national gas and power laboratory is 3406 kW, which is more than 100 kW higher than what Tengfei group announced.

If this is put in other units or research institutions, it will not be blown to the sky. As a result, Tengfei group is very good. It can only maintain the maximum emergency power for 5 minutes, which does not meet the standard of Tengfei group. Therefore, all the data are subject to 3267 kW which can last for more than 30 minutes.

When the "friends" know that Tengfei group's explanation of this domineering exposure, almost no collective crazy.

What's this for?

New rules for turboshaft engine?

The problem is to stand up and get rid of it. Don't make it so scary all at once.

The maximum emergency power lasting for 5 minutes is not included, but only for 30 minutes. If this is adopted as the standard by the headquarters, the maximum power of turbo shaft engines produced by these "friends" will all be reduced by 20% to 35%.

Among them, the model of a factory has even shrunk by 55%.

It's still a grave digging? Obviously, it's just to frustrate them.

You should know that their "friends" are living on these beautiful data. Even if the emergency power of 5 minutes will make the turboshaft engine scrapped directly, the brilliance of this period has been unprecedented.

What's more, the 5-minute maximum emergency power is not an original one in China, but a universal vortex shaft standard in the world. How can you change it?

However, before these "friends" raised questions, a motion from Tengfei group assessed by national gas and power laboratory plunged them into collective fear.

It turns out that Tengfei group hopes to take a series of mature experience in the test run of wd-63zb high-power turboshaft engine as the national standard, so as to promote the whole country and let the relevant manufacturers criticize and correct.

Originally, these "friends" still felt that Tengfei group's modesty was nothing serious. After all, the domestic turboshaft engine test was conducted by the former Soviet Union, and the extensive test situation was basically the status quo of the whole country. Even if Tengfei group broke the sky, could it break through the status quo?As a result, Tengfei group has not only broken through, but also broken through to the sea of stars.

The whole test run time shall not be less than 20000 hours, and the real aircraft flight test shall be conducted for more than 8000 hours.

In addition, 4600 starts and 2300 engine reverse tests are required in 2500 hours of acceleration test.

In flight test, flight envelope, climb, rapid take-off and landing, high impact landing, air start-up, high altitude disease elimination, overall adaptability of plateau, etc. should be evaluated

This next "friend business" is really crazy, to know that their turboshaft engine on the test bench can run even if it is successful, but the standard of Tengfei group can only run the most basic requirements.

The remaining items are not considered as engines, which is a life-long toss.

It's hard for these "friend merchants" to bear.

Even if I can bear it, I can't afford so many resources.

Among other things, the flight test of turboshaft engine needs at least a helicopter, right?

The vast majority of "friends" can't afford to play with this condition alone. You know, helicopters are not cheap. What's more important is that you have to refit your Vortex shaft if you want to go up. Who has the ability?

What's more, according to the standard of Tengfei group, one helicopter is not enough. At least three to five helicopters are needed to play well.

Many "friends" can't even afford to play with one, let alone three or five.

In contrast to Tengfei group, not to mention how powerful they are in the field of helicopters, they can build real helicopters, and they have no shortage of them, not to mention the corresponding modification ability.

So it's not easy for people to play this game, but what about them? That is to push on the last ditch.

Because of this, these "friendly merchants" are called a group of people's indignation. As a result, before they get angry, they are all turned into chicken dung by the words of the head of the headquarters.

"Well, there is more than one standard set by Tengfei group. Come and have a look. These are the key points!"
