Whether it is okay or not, data is the last word, so he opened the data and continuously observed the inside of the engine through terahertz scanning. There are three requirements for www.biquge.info engine, the first of which is working stability. The second is the technique of the vector nozzle, and the third is the working time. In the first ground test, this engine had to work stably for at least a few hundred hours before it could pass the acceptance.

It's just that the Chinese New Year is approaching, how can Zhao Heng have so much time to play happily with them? The Chinese New Year is the most important festival in China, so he has to stop all work during the New Year.

It's a pity that the miniature sixth-generation turbofan engine died down after two minutes, but fortunately it was a minor problem. Solved in less than ten minutes.

"The sixth-generation aviation engine blades are hollow blades, can you use dim sum when installing? The afterburner cylinder needs air from an outer duct for cooling! What do you guys think about blocking that vent in the duct! Think the blades don't creep fast enough? Or think that the service life of the blade is too long! And all of them are doctoral students! ”

He scolded loudly, in fact, he didn't blame the doctoral students for this, this was Zhang Qiming's intention, he just deliberately blocked the eye of the storm to find trouble for Zhao Heng. Too many people's theoretical knowledge is suddenly confused, and they are blind when it comes to practical operation, which is a typical high-level talent and imbecilability.

Zhao Heng is obviously not this kind of person, he tinkers with experiments every day, even if there is no Xiao Hei and no terahertz, he can also understand the trick here. This made Zhang Qiming very relieved.

You can rest assured that the task will be handed over to Zhao Heng, because there are too many parts and components on the engine, and it is too precise. In other places, Zhang Qiming couldn't do it if he wanted to. So you can only do it in the eye of the storm.

He originally wanted to make a fuss about the binary convergence-expansion vector nozzle, but it turned out that it would affect the performance of this engine, so he gave up. To try a person, you have to start from all aspects.

Project Tornado isn't just one of the Wind Shadow experimental models. There are many, many models, many, many aspects to be carried out, so he saw that this person could suppress his subordinates and solve scientific research problems.

He was relieved, so that he could live out his old age with peace of mind, and he should have retired a long time ago. Twenty years ago, it would have been time to unload and return to the field. It is still on the front line of research and development. It's because there's no one available.

The runaway that he cultivated before, he can't use it, he can't use it, and it's barely a person who can use it or a two-five boy, he doesn't know what will happen if he hands over 611 to that two-five boy, but he doesn't have to worry about it now. The guy in front of you is pretty easy to use, isn't it?

Zhao Heng was targeted like this, and Xiao Hei couldn't detect people's hearts no matter how powerful he was. Terahertz can scan no matter how much it is true, and it doesn't know what is going on in the deepest part of the human heart. So he didn't know that he had been targeted by Zhang Qiming.

"The combustion chamber is a little unqualified, the sound of this engine, and the tail flame spray is not normal! With the double-layer floating wall design, the gap between the outer and inner riveted thin plates is too small to expand freely. It was originally a super long time of 5,000 hours, but you knocked out 4,000 hours of life, and when you do it in the future, can you grow snacks! Yes! His angry scolding was still echoed in the workshop.

They were all busy, the doctoral students were taking notes, and even two little girls were scolded and cried. Zhao Heng is accustomed to the control of the robotic arm in experiments, and accuracy is his minimum requirement, and these researchers are not so advanced, so they will have such and such problems.

"The engine is the lifeblood of the aircraft! Do you understand the fate gate! This is a joke with the life of a pilot! What is the most important thing to do your research! Constantly improve something! Do you know how to keep improving? Suddenly turned off in the sky, do you expect our sixth-generation turbofan engine to achieve a second ignition in the air like the AL-31F! After Zhao Heng finished speaking, he felt that something was wrong, so he quickly shut up, but unfortunately the doctors laughed.

And the confidential staff was inexplicably next to him, and he laughed out loud like this when he was scolded?

There is also an allusion in this, when they were still in college in the ivory tower, the professors would tell a joke, in the space engine, only the AL-31F is not afraid to stall, why is this? This thing AL-31F, this old Maozi's engine often makes awkward noises in the sky, and when it is awkward, it turns off.

What is the concept of an airplane going out in the sky? But this problem was simply solved by the fighting nation Lao Maozi. A liquid oxygen chamber was added to both sides of the engine, and the flame was not afraid to turn off, and the second ignition would be fine. This is a classic joke of the fighting peoples on the aero engine. So when he said it, it caused a lot of laughter. Because Lao Maozi is used to the industrial roughness and leaves.

Zhao Heng waved his hand, it's good to laugh at this joke, after all, this engine is still the engine on many main combat aircraft, although it has been changed by my dynasty, but it still can't change the fact that it is shoddy.

"Alright, alright, stop laughing. They have that national character. We turned back to the turbofan engine in front of us, mounted on the Wind Shadow. I almost went down the old way, the shoddy old way. Don't laugh at the doctoral student in charge of riveting and welding to write a 10,000-word written report at night, don't use electronic files, but write them by hand. ”

The face of the doctoral student in charge of riveting and welding changed abruptly, and the 10,000-word written report is not a review? How old are you still writing a review! I haven't written it since I was a child!

The friends in the same industry are all smiling happily, most of the domestic scientific research is the ability to break through the sky on paper, many things are designed, but they can't be done. Weak hands-on ability is a common problem for my researchers.

They cherish this opportunity to practice, the miniaturized turbofan engine, only time, if you don't consider that aviation kerosene is too expensive, put it on the car, can make the car fly!

"The thrust is normal, the technology of vector thrust still needs to be improved, and it is a waste to still use binary vector!" He complained, counting the engine's data in detail in the database.

Xiao Hei uses accelerated simulation to expose many problems. Then make corrections.

Most of the accessories for this cutting-edge engine can be replaced off-site. Otherwise, just dismantle one engine and dismantle it until next year. It's all modular. The top-of-the-line design can reduce the number of tools used to 11. Quite convenient and quick.

"The maximum thrust is 70 kN, the intermediate thrust is 45 kN, the total pressure ratio is 35, the bypass ratio is 0.3, the pre-turbine temperature is 1577-1600 °, and the thrust-to-weight ratio is 10.2."

A group of data was reported to Zhao Heng, Zhao Heng nodded with satisfaction, better performance than F119, it is close to the data of F135, and the most critical thing is miniaturization! That's the biggest point of this engine.

"Stop." Zhao Heng ordered, which made this group of doctoral students wonder for a while, ground tests are generally more than 1,000 hours. And Zhao Heng actually announced that it would stop.

Seeing that no one was moving, he shouted loudly, "Stop! Don't burn money! I still think that burning the engine can keep you warm, deliberately! ”

The engine burns jet fuel, so that the whole workshop is hot and baked. He's right, you can really keep warm with the engine on.

"Shut down." The doctoral students shouted in a hurry and went to turn off the engine.

"This batch of engines is considered to be acceptable. Most of the problems have been solved. Want to know why I say that. I'll wait until you eat for a few more years. "He deliberately concealed the importance of the simulation experiment.

This is deliberate, Zhao Heng understands very well that he is telling them that it is simulated now, and they will not believe it.
