Super military empire

Zhenren Ziyang glared at his subordinates severely, while Liu Yijiu looked at Zhu Hudao with a serious face, but secretly gave him a thumbs up. He was suffering now.

Such people are everywhere, but now they are being scolded by the kind people, I don't know if they will be more honest in the future.

Even the cleaners understand what these officials think is not important. It is not so easy for laymen to guide experts.

Comrades like Johnson are the real good comrades. Didn’t see, Johnson also didn’t understand, didn’t know, and there was no problem at all?Besides, this test is important or not, whether time is wasted, or whatever, the test flight will be carried out tomorrow, and the previous time will not be retrieved.

Before, Liu Yijiu would continue to fight, but now he has not.

Not everyone is like Johnson.

Moreover, some officials, although they say they are not high in status, hold grudges. Once they are treated badly, even if it will not cause too serious consequences and impacts, it is troublesome enough for Liu Yijiu and a waste of time.

"Just ask if you don’t understand, but don’t make a blind assessment on the technical side! You comrades are like this, you have to ask about everything, and don’t be humble..." Seeing everyone staring at him, especially Long Yao Hua and Liu Yijiu, especially Liu Yijiu's little bastard's eyes, the real Ziyang who didn't want to say anything, had to teach the middle-aged people who followed him.

However, this sounded heavy, but in fact it was just like lifting a stick high and lowering it gently.

No one cares, maybe it is this attitude.

In order to make them divert their attention as soon as possible, Zhenren Ziyang restored the topic to its original track, "Honesty comrades, please continue. Tonight, tell us about the importance and role of fighter testing in popular science. In this way, Comrades can also understand the difficulties in their future work, and will not use layman's eyes and thinking to consider problems..."

Zhu Hodao did not start directly, but stared at Liu Yijiu.

Liu Yijiu was so angry that he didn't fight, as if he wouldn't let him speak, is he so cruel?

Immediately he said with dissatisfaction, "Zhou Chief, let me introduce the low, medium and high speed ground taxiing experiment. Although this is very simple for us professionals, there are some complicated things in it and why we should do it like this. They don't know..."

It's okay to explain, so that people who don't understand will come to take care of the profession again to do things that should be professional but not professional.

Zhu Houdao rolled his eyes from Liu Yijiu, feeling distressed in his heart, and stared at the interjecting guy again before beginning to introduce.

"Low, medium and high speed taxiing. Each type of taxiing has different detection content. After the on-board in-loop test is completed, all the problems encountered are resolved, and the low-speed taxiing test is started. The low-speed taxiing is mainly based on the aircraft The flexibility of ground taxiing. In the process of fighter design, the take-off conditions of the fighter need to be considered. Therefore, it is necessary to have requirements for the fighter’s ground taxi capabilities such as turning radius and taxi speed. Low-speed taxiing is used to detect Do these specifications of the fighter plane conform to our design. At this time, our fighter plane is a tricycle. However, our tricycle is more expensive than ordinary tricycles and is worth hundreds of millions..."

These things are definitely not clear in a few sentences.

But they have to explain, Zhu Houdao uses the simplest language to explain the most professional content, but the last metaphor makes many people laugh.

"Your tricycle is too expensive!" Johnson heard this theory for the first time.

Fighters and tricycles, one is the most advanced weaponry in the world, the other is just the most common thing, no matter how advanced it is, it is impossible to fly so advanced.

"The low-speed taxi test has results, until there are no faults and meets our design index requirements, the medium-speed taxi will be carried out. The medium-speed taxi, using a speed in the range of 60-100 km/h, and Every speed has to be tested in order to examine the fighter's rectification ability. This kind of experiment, imitating the f-14 has been carried out 134 times from the beginning to the present, and 228 hidden dangers and design problems have been eliminated..." Zhu Hodao When introducing the medium-speed taxiing test, the important role of this kind of test on the hidden troubles of the entire fighter system was particularly emphasized.

"It was not tested many times at the beginning, why would there be faults? Why didn't it find out before, and it could be checked out during such a test?" Real Ziyang couldn't understand it.

According to his thoughts, or according to everyone's thoughts, the pilots of the fighter jet were allowed to simulate driving in the cockpit at the beginning. Shouldn't all the hidden dangers and malfunctions of the fighter jet be checked out?

The low-speed taxiing behind is to test the performance of the fighter.

Shouldn't the performance be tested for moderate speed taxiing?

"It is indeed to test the performance. This is to test the correcting ability of the fighter. The difference between the medium-speed taxiing and other taxiing tests is that after the fighter is started, it begins to taxi on the airport runway. During the entire taxiing process, the pilot does not Do any operations on the fighter plane, place the fighter plane on the runway and taxi forward only by the thrust of the engine. If the plane deflects to one side and cannot walk in a straight line, it means that there is a problem with the fighter plane! There are many factors that cause deviation, which may be the shape. Asymmetry leads to asymmetrical aerodynamic forces; it may also be a problem with the landing gear-including the landing gear installation position, brakes, etc., may cause the aircraft to deviate. It must be improved to allow the fighter to run in a straight line, and a long straight line In order to enter the next high-speed taxi test."

Hearing all the kind explanations, many leaders did not take a breath.

They knew that the development of fighter aircraft was very complicated and difficult, but they never thought of it to such an extent.

Just the ground test before the test flight, there are so many doorways.

Moreover, during these tests, it is also a process of making subtle modifications to the entire design plan. The entire project team does not end up with the production unit after the design drawings are completed.

"The problem of deviation has always troubled us for a long time, and the progress has been delayed for about half a year. It is because of this test that our first flight work has to be pushed back again and again..." Liu Yijiu sighed and explained to Long Yaohua and Zhenren Ziyang.

In the entire world, it is estimated that China has conducted the most experiments in this area.

"This is not caused by our lack of design capabilities. Of course, there are also factors in this area. It is more caused by our poor industrial foundation, insufficient processing and manufacturing precision, and insufficient assembly capabilities. Therefore, we are developing fighter production. In the process, we must also solve the problems of production supporting various top-level processing and manufacturing equipment and even materials."

A fighter is not only related to design and production, it is a high degree of integration of the entire industrial system.

The reason why Liu Yijiu said these words is to tell the bosses above that if you want to have better weapons and equipment, you can’t just let this project run, but you have to make the same improvement in various basic industries related to this project. Row.

"Industrial foundation is very important, and we all know this. Comrade Xiao Liu, our fighters are now ready for the first flight. Does this mean that our related supporting industries have also been upgraded?" The real Ziyang people care about industry most. basis.

If it were not for China's poor industrial base, would the Americans dare to say that?

"Relatively speaking, it is a little improvement. Chief, although we can manufacture it, it does not mean that our foundation is already very good. The United States and the Soviet Union have a good industrial foundation, and their fighters can be mass-produced in a short time. Equipment, hundreds of aircraft may be produced a year, and even if we do it, because our talent pool is not enough and the industrial base is insufficient, the number we can produce will not exceed 25 each year..." Liu Yijiu was helpless.

The truth in this is really too deep.

For the heads above, they cannot figure it out, at least, in a short time.

It is enough to tell them the influence or importance of the industrial base on these advanced manufacturing industries.

Then Liu Yijiu asked Zhu Houdao to continue to talk about the problem of the high-speed taxi test.

"The high-speed taxiing experiment is used to determine the degree of agreement between the aerodynamic force of the fighter and the design value. Only the fighters that completely match can dare to carry out the flight test!" Zhu Houdao explained the role of the final ground test before the test flight.

Without the high-speed taxi experiment, the fighter plane would never fly!

"Under the requirements of aerodynamic force, it is necessary to carry out the experiment of raising the front wheels and then lowering them during the high-speed taxiing phase. That is to say, the pilot pulls up his head after taxiing to a certain speed. At this time, the aerodynamic force of the aircraft should be able to raise the front wheels. Then push the stick again, the front wheels of the aircraft can return to the ground. Then take back the aerodynamic parameters recorded by the relevant equipment on the aircraft and compare them with the data from the wind tunnel, and correct the calculation model. Make the first flight. At present, all these tasks have been completed, and all the results have reached the best level of design. Our imitated f-14 is just waiting to fly!"

Indeed, for this day, they conducted various experiments for more than two years.

Even now, the fighters parked in the assembly workshop are still undergoing operational tests of various parts.

In order to make the Chinese giant panda soar into the sky!
