Ziyang Zhenren glanced at Liu Yijiu meaningfully again, and didn't say anything.

Jiang Sen opened his mouth, "Director Liu, are you responsible for so many projects?" Every project requires a lot of energy! ”

There was no sarcasm in his words, but when it reached the ears of some people, it smelled like that.

Liu Yijiu's expression was even more embarrassed, indeed, he did not fulfill the responsibility of the chief designer, because many times, he was mainly responsible for the overall design, and he only appeared when there was a problem, made modifications, and even the double three project only put forward some concepts and performance requirements, and did not interfere too much.

Strictly speaking, he, the chief designer, is unqualified.

"Director Liu is indeed more suitable than us as the chief designer, because all the fighter projects, under the auspices of Director Liu, have saved us a lot of detours......" As soon as he said this, Zhu Houdao was even more resentful.

Although fighter design requires a very high level of talent and experience, Liu Yijiu must not be measured by such a simple thing.

The more people who know him, the more shocked they are, from the most basic firearm design, to the design of conventional heavy weapons such as tanks, to the design of missiles, the guidance of radar, etc., and now to warplanes, as well as warships equipped by the navy, and a series of technologies, I didn't see the technicians of 701 running to Rongcheng every three or five times, in order to need Director Liu's construction?

It's a demon!

If it weren't for a staunch atheist, Zhu Houdao would feel that Liu Yijiu was definitely reincarnated by a certain monster, and it was a future monster who ran to this era.

He has been in the aviation industry for decades, and most of his life has passed, but he has not even made a copy of the fighter that should be entered, if it is not for Liu Yijiu, and even the first flight of this fighter plane is not so fast, how can he not be resentful?

"Alright, let's take a look at the fighters. How well are you preparing? Liu Yijiu heard this. Worried that the other bastards would start to make sycophants, he didn't intend to let them continue.

The fighter is nothing else, and if he does not occupy the position of chief designer, others simply will not get the fighter according to his ideas!

"Yes. Let's take a look at the fighters. Jiang Sen also sensed that something was wrong, and many of the people brought by Ziyang Zhenren looked at Liu Yijiu meaningfully.

Such a thing is definitely a criticism.

"The equipment work before the first flight of the fighter has been completed, and we will do one last inspection before the flight. Check if there are any faults in each part......" Zhu Houdao began to introduce the situation to the group.

The newly assembled imitation F-14, still unpainted, has the most basic metallic luster on the outside, and some of the oxidized titanium alloys are even beginning to show black and gray.

Liu Yijiu suddenly found that the F-14 with a black body is very beautiful.

The only fly in the ointment is that not only titanium alloy is used on this body, but also many other materials, which makes the fighter body black with a lot of other colors, which looks a little mottled, and for assembly, many places have not been erased with paint marks or anything......

It's an ugly warplane!

"And no paint?" The corners of Johnson's mouth twitched. Originally, I didn't plan to ask, but seeing that Long Yaohua, Ziyang Zhenren and others had some twitches on their faces, they couldn't help but ask Liu Yijiu.

Liu Yijiu nodded, "After the first flight, it will be inspected, and many places will be disassembled after coming back. You have to repeat the work, which is not only time-consuming but also costly. ”

Liu Yijiu didn't feel embarrassed about this matter.

Now I didn't go to pit anyone.

"Does it affect flight?" Ziyang Zhenren didn't understand, and he didn't meddle in these things. Long Yaohua and the others know everything, and they don't say anything.

"No, it doesn't affect. Because at the time of the first flight, it was only to test whether the fighter could fly, whether the various systems inside the fighter were faulty, whether there were problems with the assembly, and there would not be too high speed to fly. There won't be any slightly more complicated maneuvers either. Therefore, whether the painting has a big impact, according to the expected plan, the first flight, only 7 minutes of flight, complete takeoff, acceleration in the air, slow climb in the air and turning and other conventional performance tests......" Liu Yijiu introduced the situation to the leaders of the group.

After the completion of the ground test, the fighter is faced with the first flight work.

Originally, if it weren't for the huge pressure on the entire country's national defense now, and the Americans insulting China's defense industry like that, the first flight would have been more cautious and simpler, and they would not even have done these actions of climbing in the air.

"How's the ground testing going?" Ziyang Zhenren obviously made preparations.

After the final assembly of the fighter and the assembly of various systems, the fighter also needs to undergo a series of ground tests.

The two turbofan afterburner engines of the disassembled F-14 that were originally used for research were used in this imitation prototype.

It is mainly used for low-speed, medium-speed, and high-speed taxiing on the ground on the runway.

In the course of these tests, a lot of problems and faults with the fighter itself will be discovered.

With no experience, no references, the only thing that can be done is to do more experiments. So, both engines have always been on this prototype.

"The static test and the static failure test are very good, this imitation aircraft number 03 is the first prototype for flight tests, as long as the first flight is successful, there is no problem, we will produce 4 more prototypes for flight tests...... Ground tests, from the real yàn on the plane to the low, medium and high-speed runway taxiing, have been at least 100 times ......"

"What is on-board in the ring yàn? Why do you do it so many times? "Ziyang Zhenren is very incomprehensible.

Although the performance requirements of the fighter are carried out and the production and manufacturing are complicated, the ground test should be far less important than the air test.

Of course, this is for those of them who do not understand the importance of aviation aircraft, especially prototype testing, ground testing before the first flight.

Liu Yijiu didn't bother to explain these professional technical issues to these leaders, anyway, it was useless for these leaders to know these things, and besides, they were so busy that even if they explained it now, they couldn't remember how long, and it was a pure waste of time to explain to them.

When the chief was ashamed to ask, he couldn't just not explain, so he directly handed over this task to Zhu Houdao.

As the deputy chief designer, I naturally need to do these things.

After getting Liu Yijiu's signal, he began to explain the content and role of the ground test work of the fighter to these technical novices: "Chief, the so-called on-board in the ring is real, that is, after our fighter is produced, the fighter is connected to the power supply, and the hydraulic pressure is applied, so that the whole fighter is no different from before the flight, and the test pilot is in the cockpit, and there is a display screen in front of the plane that simulates the flight of the aircraft. The content of reality is no different from the various actions of a fighter plane in the air......"

"What does this do? Always flying on the ground, it doesn't have much effect, right? No wonder your first flight work has been postponed again and again, it's not that your fighter planes are not ready, but that you have wasted your time......" A middle-aged man next to Ziyang Zhenren said with a frown.

When Liu Yijiu heard this, the corners of his mouth twitched, he looked at the man, and didn't say anything.

Such an idiot is really a bit annoying.

And the other people next to him also had the expressions of the people of the Ninth Academy wasting their time.

Zhu Houdao was so angry that he almost spurted out a mouthful of old blood.

However, in the end, there was no seizure, and he understood why Liu Yijiu gave him this matter, not so that he could show his face in front of the chief, but so that he could bear the disgust of those ignorant officials.

He immediately took a deep breath and said to the man very solemnly, "The ground test of the fighter plane, the critical range dù even exceeds the air test of the fighter!" Because if the ground test cannot be passed, it is impossible for the fighter to go to the sky, otherwise, as soon as it reaches the sky, the situation encountered is to fall down...... During the on-board ring test, the pilot pulls the steering stick in the cockpit, and because of the hydraulic pressure, the rudder surface will be deflected according to the design rules as if it were flying in the sky, and the scenery such as the sky and the earth line displayed on the display screen will also change accordingly. It's equivalent to a pilot sitting in the cockpit and flying according to the vision in front of him! This kind of test is used to test whether the aircraft can be controlled normally. If you can't control it here, when it actually flies, no matter how powerful the pilot of this fighter is, you can't control it! These things are clear even to the cleaners in their assembly shop! There is time that should be wasted, and it is absolutely impossible not to waste it! ”

When he said the end, Zhu Houdao was even a little angry.

That's the most basic thing.

If you don't understand, don't ask about these professional and technical things, just come here and see if the fighter can fly.

You have to pretend to know technology very well, or be kind and studious, but you don't know that you can only be despised.

With these basic tests, even the assembly workers in the final assembly workshop know what they are used for! Even if these leaders knew, what could they do? Are they still doing these jobs, and they can do it?

Although he complained in his heart, he didn't show anything on his face.

At first, the middle-aged man who said that they were wasting his time, and when he heard Zhu Houdao's sarcasm, especially when he said that he was not even as good as a cleaner, his face turned red, but he couldn't say anything......
