Chapter 1119

We have to have a brain failure, let alone stay on the spot, because on the noisy test bench, the column of turboshaft engine fuel consumption rate shows 0.28.

This value can become a fuel-saving miracle at 0.35. For domestic turboshaft engine industry, it is not a miracle, but a miracle.

To increase the take-off fuel consumption rate by 0.28 means that in the helicopter take-off stage, which requires the most engine power consumption and is also the stage with the largest fuel consumption of turboshaft engine, the fuel consumption per kilowatt hour is only 0.28 kg.

That is to say, when wd-63zb high-power turboshaft engine runs at full load of 3000 kW for one hour, the required aviation fuel is 840 kg.

It seems very scary. After all, zhi8plus is equipped with three wd-63zb high-power turboshaft engines. If they all come like this, what is it if they are not oil tigers?

On the other hand, the turboshaft 8e engine equipped with zhi-9, which is imitated from the French ahye turboshaft engine, will not consume 276kg of fuel even if it runs for one hour with 522kw of take-off power.

It is much less than that of wd-63zb high-power turboshaft engine, even though the maximum take-off fuel consumption of turboshaft 8e is 0.53.

If we compare it like this, we will not talk about martial arts.

We should know that the wd-63zb high-power turboshaft engine is a high-power turboshaft engine; the turboshaft 8e is just a low-power turboshaft, even if the power is full, it will not reach the fuel consumption of the wd-63zb high-power turboshaft engine.

But does this mean that the fuel consumption of vortex shaft 8e is low?

Obviously not. On the contrary, the fuel consumption of turboshaft 8e is quite high, even twice that of wd-63zb high-power turboshaft engine.

Because the wd-63zb high-power turboshaft engine consumes only 146 kg of fuel per hour at 522 kW, almost half of that of the turboshaft 8e.

It can be seen that the real oil tiger is vortex shaft 8e.

It is true that the fuel consumption of vortex shaft 8e is too high, which leads to the fact that the domestic zhi9's range is always less than that of the original French goods, which makes the army's attitude towards zhi9 quite complicated.

Equipment, straight 9 can't install too much, not to mention, short legs, unable to carry out high-intensity military tasks, a complete chicken.

If we don't have equipment, we can't afford to lose money after investing so much money in more than ten years.

It is the repeated hesitation of the army in Zhi 9 that gives Tengfei group Zhi 12 a chance to cut in.

Even though the previous generations of zhi-12 also pull the crotch, all kinds of problems emerge in endlessly, but the wd-43z turboshaft engine equipped on zhi-12 has a fuel consumption rate of 0.4, which can meet the army's minimum demand for the voyage under the condition of full load. Only in this way can zhi-12 endure all kinds of problems and hold its nose to support.

In this way, the two helicopters did not have the worst, only worse than rotten process, zhi9 and zhi12 both got orders from the army.

For zhi12, it's a complete survival. For zhi9, it's also a relief. At least their public relations strategy is to use the right routine.

Yes, zhi-9 has also been improved. It's just that it's not an improvement in technology and technology, but an improvement in running departments, finding leaders and lobbying public relations.

Doesn't it mean that the fuel consumption of vortex shaft 8e is high?

Just change the value. The maximum take-off fuel consumption is determined by the daily maximum power at the time of take-off. The engine will explode just a few seconds before takeoff. What's the universality?

If you want to use it, you need to use the daily cruise fuel consumption rate, which is the most commonly used and true.

What is cruise power of vortex shaft 8e? 350 kW.

As a result, the fuel consumption of vortex shaft 8e immediately dropped from 0.53 to 0.4.

This is to take care of the face of Tengfei group. Otherwise, according to their internal test results, the fuel consumption rate should be 0.38 to 0.39, making it the only high-performance turboshaft engine with fuel consumption rate below 0.4 in China.

At that time, there was no measurement standard for the fuel consumption rate of a turboshaft engine in China. The superior department accepted the reliable maximum fuel consumption rate of take-off of Tengfei group and the daily cruise fuel consumption rate of a turboshaft manufacturer.

As a result, according to the official media reports, the fuel consumption rate of wd-43z turboshaft engine and turboshaft 8e are both 0.4.

In addition, the power difference between the two engines is not bad, and each index is similar, so it gives people the feeling that the performance of the two engines are almost the same. Some people even think that the turboshaft 8e will be a little bit better. After all, the turboshaft 8 is an imitation product of France. The European technology is better than that of China. Of course, the turboshaft 8 is better than the pure domestic one.

With the pearl jade of vortex shaft 8e in front, can other vortex shaft transmitter factories still play like this? What kind of R & D is there? Is it easier to focus on digital games?

Don't the money saved be used as bonus and welfare for employees?

For a time, the performance index of domestic turbo shaft transmitter is in such a mess that foreign media who do not know the truth all exclaim that China has become a powerful country in R & D and production of turbo shaft transmitter overnight.But actually? The quality of the turboshaft transmitters equipped by the army is worse than before.

If not, he would not have developed any turboshaft industry standard by using wd-63zb high-power turboshaft engine to test in the national gas power laboratory.

It is to set up a model and at the same time kill the unhealthy tendencies in the industry.

"How's it going? everybody? The maximum take-off fuel consumption rate of wd-63zb high-power turboshaft engine is 0.28. Listen well, it's not the daily cruise fuel consumption rate, let alone the low load fuel consumption rate. It's the maximum take-off fuel consumption rate. 0 Tengfei group has achieved below 0.3... "

When people in charge of "friend business" were looking at the value of 0.28 and their expressions were wonderful, the head of the headquarters took the microphone and said, "what's the concept? The daily cruise fuel consumption of the turboshaft engine produced by you is 0.12 higher than the fuel consumption index with the largest fuel consumption? Do you want me to elaborate on other aspects? "

As soon as the voice fell, the head of the headquarters looked solemn, and his tone suddenly became sharp: "I still said that, Tengfei group can do it, how can you not do it?

Is it because of the lack of funds or policies? Even if you want to find a partner, you have to pay 20 million from the headquarters to help solve the problem. What about Tengfei group?

At that time, I was still buying popsicles and ice-cream, not to mention comparing with you, but I couldn't compare with a branch of your company, but now?

Others of Tengfei group have achieved the world advanced level of domestic turboshaft engine by themselves. What about you?

Who gave you the courage to introduce so many foreign technologies that you didn't do as well as the original ones? Don't be cheeky, his grandfather, don't you want to be cheeky? "

To their surprise, the head of the headquarters would be in a rage at this time, and they were immediately shocked into silence.

The head of the headquarters looked around the crowd with a gloomy look, and then said in a deep voice: "in the future, the technical standards of turboshaft engines will all refer to wd-63zb high-power turboshaft engines. If anyone is not convinced, he will make me a 3000 kW high-power turboshaft. I will naturally use your standards, otherwise Hum Let's wait for it to go out of business! "

Before the voice fell, the head of the headquarters threw the microphone to the staff and walked away without looking back
